EXPECTATIONS YOU MUST let go of IN YOUR 20s

 


 EXPECTATIONS YOU MUST let go of IN YOUR 20s


1.    You’re meant to be extraordinary.
Extraordinary people are just that—rare. Recognizing this doesn’t mean you’re giving up on your potential, it means you’re dissolving the illusions you have about what it means to be your whole self and live your best life. We tout the “one in a billion” success story as though it’s the natural end goal of working hard and actualizing yourself. It’s not. The real question is what work are you willing to do even if nobody claps? What will be worthwhile if it goes unacknowledged? How will you feel loved by a few people if you aren’t recognized by many? Finding the exceptional in the ordinary is the real extraordinary.

2.    You’re at the beginning of your life.
Some of you reading this will not make it through your 20s. Others won’t make it past midlife, or even past this year. Keep a skull on your desk if you must—nobody assumes they’ll die young, but that doesn’t mean they don’t.

3.    Your faults are more forgivable, and your attributes are more exceptional.
Believing that you’re less responsible for your misgivings and that you’re more exceptionally skilled at your strengths is the mindset to which many people default, but it ultimately just keeps you small. If you don’t acknowledge the magnitude of the poor choices you’ve made, you’re bound to justify doing them again; if you live and act as though you can slide by because you’re ever so slightly better than everyone else, you’ll never actually try.

4.    You can literally be whatever you want.
If you don’t have the IQ of a rocket scientist, you cannot be a rocket scientist. If you don’t have the coordination to be a professional dancer, you won’t be a professional dancer. Wanting something badly enough doesn’t qualify you to have it.
You cannot be whatever you want, but if you work hard and don’t give up and happen to be born to circumstances that facilitate it, you can maybe do something that crosses your abilities with your interests. And if you’re really smart, you’ll figure out how to be grateful for it, even on the difficult days.

5.    You can outsmart pain.
You cannot think your way out of pain. You cannot predict it, or avoid it, or pretend you don’t feel it. Doing so is living a fraction of the life you were meant to, and it will make you a fraction of the person you’re supposed to be.

6.    Love is something other people give you.
 
People cannot transmute emotions, which is interesting to consider when you realize how utterly consumed the human race is with the concept of getting other people to love us. This is because when we think other people love us, we give ourselves permission to feel love. It’s a mind game, one in which we rely on everyone but ourselves to allow us to feel what’s already inside us. (If you think love is something that exists anywhere but within your own mind and heart, you will never have it.)

7.    Feeling something deeply means it’s “meant to be.”
The intensity with which you experience something (or someone) does not equate to how “destined” it is. Many people deeply feel they’re called to be famous in their field, but they do not have the skills or the grit to make it; most people who get married feel deeply they’re in the right relationship, but that doesn’t mean it won’t end in divorce someday.
Breakups are meant to be. Job losses and hurt feelings and disappointments are, too. How do we know this? Because they happen often, they are the most pivotal redirects. Forget the final picture you want your life to amount to. It will never exist the way you think it should, and in the meantime, it will only ensure that you waste what you do have in the moment. There’s only one final destination here—the only thing you’re rushing toward is the end of your life.

8.    If you work on yourself enough, you won’t struggle anymore.
If you work on yourself enough, you’ll understand what the struggle is for.

9.    You can control what other people think of you.
You can control how you treat people, but you cannot actually control what they think. The idea that behaving a certain way will elicit a certain response is a delusion that will keep you puppeteering through your life. It will distance you from the person you want to be and the life you want to live. And for what? People are going to judge, criticize, condemn, love, admire, envy, and lust based on their own subjective perceptions regardless.

10.    Hard work guarantees success.
If you’re looking for any one particular outcome as the end goal of your hard work, you’re most likely going to end up disappointed. The point of hard work is to recognize the person it makes you, not what it "gets" you (the former you can control; the latter, you can’t).

11.    Your thoughts will change themselves when your circumstances change.
Most people assume that when their lives change, their thoughts will change. When they have someone who loves them, they’ll think they’re worthy of love. When they have money, they’ll have a different attitude about it. Unfortunately, the opposite is true— when you adopt a new mindset about money, you’ll start behaving differently, and then you’ll be in a different fiscal position, for example. Your mind creates; it is not created.

12.    Other people are responsible for your feelings.
The only place you have complete control over what’s said to and around you is in your home. Otherwise, you exist in a diverse world of many people and opinions of which are likely to “offend” you at some point or another. If you want to assume you are the focal point of everyone’s life and ascribe meaning to every passing comment and idea that
 
doesn’t soundly resonate with your own belief system, you’re going to live a very difficult life. Changing how other people think and treat you is not a matter of how outraged you get, but how willing you are to explain, teach, and share. Defensiveness never precedes growth, it stunts it.

13.    Emotional  intelligence  is  infallible  composure;  self-esteem  is  believing  you  are supremely, completely “good”; happiness is a product of not having problems.
Emotional intelligence is the ability to feel, express, and interpret your feelings productively; self-esteem is believing you’re worthy of loving and being loved despite not being supremely, completely “good” all of the time; happiness is a product of how you cope with your problems and whether or not you see them as the opportunities they are.

14.    The right person will come at the right time.
You will not be ready when the love of your life comes along. You also probably won’t be ready when you see the listing for your dream job, or to buy a house or maybe have a kid or maybe quit that job and try to write the book you keep thinking about or get sick or lose a relative or die yourself. If you wait on the feeling of “readiness,” you’ll be waiting forever, and worse, you’ll miss the best of what’s in front of you.

15.    You can postpone your happiness or save it up like money in a bank.
People postpone their happiness to keep themselves safe. They dig for another problem to have to solve, another obstacle to overcome, another passageway until they can feel the happiness they know is in their lives. You cannot save up your happiness; you can either feel it in the moment, or you miss it. It’s that simple. It’s temporary regardless. The only variable is whether or not you ever felt it in the first place.

16.    Anxiety and negative thinking are pesky irritants you just have to learn to thwart.
Anxiety is one of the main driving forces that has kept you—as well as our entire species
—alive. Struggling with a crippling overabundance of it usually means you’re not listening to it, or there’s some major issue in your life you refuse to address or take action on. The power of negative thinking is that it shows us what matters and how we need to respond to our lives.

17.    Focusing solely on your own needs will make you happiest.


Despite what many corners of the Internet would have you believe, self-sufficiency is just a precursor to happiness. It is the foundation. It is crucial, but it is not the connectedness on which human beings thrive. Committing, sacrificing, trying and trying again for the people you love and the things you believe in are what make a life feel worthwhile. Meeting your own needs is the first step, not the ultimate goal.

The Ways Your Personality Can Get in the Way of Your Success, According to Psychology

 


If you know what’s holding you back, you’ll be better placed to change.

When a team led by Nobel Prize-winning economist James Heckman combed through data on thousands of people to discover what factors matter most for success in life, they found that IQ mattered a minuscule 1 or 2 percent. What mattered a whole lot more? In a word, personality. 

Which might sound pretty terrifying to those who worry they don’t have the right personality to get ahead in life. But it shouldn’t. If research is pretty clear that character plays an outsized role in life outcomes, it’s also clear that personality can change. Measure what psychologists call the Big 5 personality traits — extroversion, neuroticism, agreeableness, openness, and conscientiousness — when someone is 14 and then do it again when they’re 75, and the two tests will bear basically no resemblance to each other. What’s more, studies show that with a little bit of effort, it’s possible to consciously change your personality if you so desire.

So to sum up, your personality can make or break your chance of success in life, and your personality is, at least to some degree, under your control. And this raises the obvious next question: Which personality traits should you try to influence?

The 7 biggest personality pitfalls

While that question will always be somewhat personal — if your definition of success is building a billion-dollar business then you’ll presumably need a different personality than if you dream of becoming a beloved local librarian — but psychology can still help answer it.In a recent Psychology Today post University of Massachusetts, Amherst professor Susan Krauss Whitbourne explains how psychologists figured out what personality traits hold people back from success. While diagnostic checklists have long existed for various clinical mental health problems, up until recently no test or inventory claimed to be able to tell you whether you had a “maladaptive” personality that was likely to keep you from fulfilling your dreams. So a team led by researcher Michael Boudreaux set out to create one.

Whitbourne’s post lays out their approach in detail, but the important takeaway for the layperson is that they claim to have succeeded. Sifting through the data the team homed in on seven clusters of problematic personality traits that were consistently associated with lower life satisfaction, worse social functioning, and other problematic behaviors like drug and alcohol use. Here they are:

Emotion dysregulation (difficulty managing stress and intolerant of frustration)
Internalizing (sadness and self criticism)
Will to achieve (lack of direction and distractibility)
Externalizing (acting out in risky behavior)
Scrupulousness (rigidity and perfectionism)
Fantasy proneness (getting lost in fantasies)
Apathy (lack of enthusiasm or strong emotions)
Reading this list, one or more of these areas might immediately pop out at you as something you struggle with, but if not, Whitbourne offers a simple 26-question assessment to help you decide if any of these personality problems apply to you. Shining a spotlight on your personality flaws might not sound fun, but as the article points out, facing up to your weaknesses can actually be empowering.

“Gaining insight into your tendencies to thwart your own chances of success is an important first step in short-circuiting a self-defeating vicious cycle. You may never be able to solve all your intrapersonal problems, but gaining insight into their effect on your life can help you be that much more likely to gain long-term fulfillment,” Whitbourne concludes.

Be bold enough to take a clear eyed look at how your personality is holding you back and you’ll be much better placed to overcome any shortcomings and actually achieve your dreams.

Patient information: Anaphylaxis symptoms and diagnosis

ANAPHYLAXIS OVERVIEW — Anaphylaxis is a potentially deadly allergic reaction that is rapid in onset. It is most often triggered by foods, medications, and insect stings. There are many other possible triggers.

Anaphylaxis is an unpredictable condition. Many people who experience it have a known allergy and some have had one or more milder allergic reactions previously. Others, who are not even aware that they have an allergy, can suddenly experience severe anaphylaxis. Even the first episode of anaphylaxis can be fatal.

The severity of anaphylactic reactions can be minimized by recognizing the symptoms early, having proper medication available for self-treatment, and seeking emergency medical care promptly. This topic reviews the symptoms and diagnosis of anaphylaxis. Treatment and prevention of anaphylaxis are discussed separately. A separate topic discusses how to use an epinephrine autoinjector. (See "Patient information: Anaphylaxis treatment and prevention" and see "Patient information: Use of an epinephrine autoinjector").

ANAPHYLAXIS SYMPTOMS — Symptoms of anaphylaxis generally begin within minutes to an hour of exposure to a trigger. Less commonly, symptoms do not develop for several hours.

The most common symptoms of anaphylaxis are hives (urticaria) and swelling of the skin (angioedema), which occur in 80 to 90 percent of reactions. Respiratory symptoms occur in about 50 percent of reactions, and are especially common in people who also have asthma or another chronic respiratory disease. Extremely low blood pressure, causing lightheadedness, dizziness, blurred vision, or loss of consciousness (passing out) occurs in about 30 percent of reactions.

Anaphylaxis can cause symptoms throughout the body: Skin: Itching, flushing, hives (urticaria), or swelling (angioedema) Eyes: Itching, tearing, redness, or swelling of the skin around the eyes Nose and mouth: Sneezing, runny nose, nasal congestion, swelling of the tongue, or a metallic taste Lungs and throat: Difficulty getting air in or out, repeated coughing, chest tightness, wheezing or other sounds of labored breathing, increased mucus production, throat swelling or itching, hoarseness, change in voice, or a sensation of choking Heart and circulation: Dizziness, weakness, fainting, rapid, slow, or irregular heart rate, or low blood pressure Digestive system: Nausea, vomiting, abdominal cramps, or diarrhea Nervous system: Anxiety, confusion, or a sense of impending doom

A severe form of anaphylaxis causes sudden collapse without other obvious symptoms, such as hives or flushing. This form of anaphylaxis occurs most commonly after a person is given a medication into a vein or is stung by an insect.

Up to 20 percent of people with anaphylaxis have biphasic (two-phase) or protracted (prolonged) anaphylaxis. A person with biphasic anaphylaxis has a reaction that resolves and then recurs hours later without further exposure to the trigger. The late phase reaction usually occurs within eight hours, but may occur up to 72 hours after the initial symptoms. A person with protracted anaphylaxis has signs and symptoms that persist for hours or even days despite treatment, although this is rare.

ANAPHYLAXIS TRIGGERS — The trigger for a person's anaphylaxis may be obvious or it may be difficult to identify.

Common anaphylaxis triggers can include: Foods: In children, hen's eggs, cow's milk, peanuts, tree nuts, fish, wheat, and soy are the most common food triggers.

In teens and adults, peanuts, tree nuts, fish, and crustaceans (shellfish such as shrimp) are the most common triggers.

Any food, including fruits and vegetables, and some spices and food additives, can cause anaphylaxis. Medications, especially certain antibiotics (such as penicillin or amoxicillin), medications for pain and fever (such as aspirin or ibuprofen), some x-ray dyes (also called radiocontrast media), and others Venom from insects, including bees, hornets, wasps, and fire ants Latex from natural rubber, found in some latex gloves, balloons, condoms, sports equipment, and medical products Allergen immunotherapy ("allergy shots"), such as those given for the treatment of allergic rhinitis (hay fever) Exercise, either by itself, or after eating certain foods (eg, wheat, celery, seafood), medications (eg, aspirin), or exposure to cold air/water Less common triggers include exposure to airborne allergens (such as horse dander), human seminal fluid, and cold temperatures.

Sometimes a specific trigger cannot be identified, even after a thorough evaluation. This condition is called idiopathic anaphylaxis. (See "Patient information: Anaphylaxis treatment and prevention").

IgE mediated anaphylaxis — In most people, anaphylaxis is caused by the presence of proteins called immunoglobulin E (IgE) antibodies. IgE antibodies are normally produced in the body for the purpose of fighting certain infections. In people with allergies, however, IgE is made in response to non-infectious substances, such as foods, medications, or insect venoms. This IgE then sticks to the outside of mast cells and basophils, a type of white blood cell.

If a person with IgE antibodies to a specific allergen is exposed to that allergen again, the cells may suddenly become activated. The activated cells release large amounts of inflammation-causing chemicals (including histamine) into the blood stream, causing anaphylaxis.

The chemicals released from the cells cause the signs and symptoms typical of anaphylaxis. (See "Anaphylaxis symptoms" above). The allergic reaction can be so strong that it becomes life-threatening; for example, sudden severe swelling in the throat can lead to suffocation.

In some people with anaphylaxis, the reaction is caused by a process that does not involve allergens and IgE. However, the symptoms and treatment are the same.

ANAPHYLAXIS RISK FACTORS — Some people are more likely than others to experience anaphylaxis or to develop severe symptoms during anaphylaxis, for example, those who have one or more of the following: Previous sudden severe allergic reaction involving the whole body — People who have had allergic reactions to a particular substance in the past are at increased risk of anaphylaxis. However, the severity of past allergic reactions does not reliably predict the severity of future reactions; people with mild reactions in the past may experience severe anaphylactic reactions in the future. Asthma — People with asthma are more likely to have more severe respiratory problems during anaphylaxis. The combination of food allergy (especially to peanuts and tree nuts) and asthma seems to put people at risk for life-threatening episodes of anaphylaxis. Other diseases — People with chronic lung disease, especially older adults with chronic obstructive pulmonary disease (COPD) or emphysema, are at increased risk of complications during an anaphylactic reaction. People with coronary artery disease and other heart diseases are also at greater risk of developing complications during an anaphylactic reaction.

ANAPHYLAXIS DIAGNOSIS — The diagnosis of anaphylaxis is based upon symptoms that occur suddenly after being exposed to a potential trigger, such as a food, medication, or insect sting.

Is it anaphylaxis or another problem? — A number of other heath problems can cause symptoms that are similar to those of anaphylaxis. These include a severe asthma attack, a heart attack, a panic attack, or even food poisoning. Evaluation by a specialist can help to clarify the diagnosis.

Tryptase is a protein that is released into the blood during an anaphylactic reaction. An increased amount of tryptase can sometimes be measured in a blood sample collected during the first three hours after anaphylaxis symptoms have begun. Unfortunately, tryptase levels are normal in many people with anaphylactic reactions. For example, it is seldom elevated in food-induced anaphylaxis

Patient information: Allergy to penicillin and related antibiotics

PENICILLIN ALLERGY OVERVIEW — Serious allergies to penicillin are common, with about 10 percent of people reporting an allergy. However, about 90 percent of people who believe they are allergic can take penicillin without a problem, either because they were never truly allergic or because their allergy to penicillin diminished and resolved over time.

People who have a remote history of allergic reaction to a medication may become less allergic as time passes. Only about 20 percent of people will be allergic to penicillin 10 years after their initial allergic reaction if they are not exposed to it again during this time period.

WHAT IS PENICILLIN? — Penicillin is one of the most commonly prescribed antibiotics. It is part of a family of antibiotics known as beta lactams. Penicillins can be classified into the following categories: Penicillin G (also known as benzylpenicillin) Anti-staphylococcal penicillins (nafcillin, oxacillin, cloxacillin and dicloxacillin) Broad spectrum penicillins

- Second generation (ampicillin, amoxicillin and related agents)
- Third generation (carbenicillin and ticarcillin)
- Fourth generation (piperacillin)


Anyone who is allergic to one of the penicillins is allergic to all penicillins. One of the major differences among the penicillins is the range of bacteria against which they are active. Penicillin G and the anti-staphylococcal penicillins treat a small number of specific bacteria. On the other hand, the second, third, and fourth generation penicillins are capable of treating a wide range of bacteria, and are therefore called "broad spectrum".

REACTIONS TO PENICILLIN — A variety of unexpected reactions can occur after taking penicillin.

Adverse reactions — "Adverse reaction" is the medical term for any undesirable reaction caused by a medication. Allergic adverse reactions are less common than non-allergic adverse reactions. Stomach upset and diarrhea are examples of non-allergic adverse reactions.

It is important to distinguish non-allergic adverse reactions from true allergic reactions. Some people report that they are allergic to penicillin when actually they have had a non-allergic side effect. As a result, the person may be treated for a particular infection with a less-effective or more toxic antibiotic. This can lead to antibiotic failure or resistance, which can be costly and prolong illness.

When reporting past problems with antibiotics, it is important to provide as much detail as possible about the reaction. Anyone who is uncertain if a past allergic reaction was truly caused by allergy should avoid the antibiotic until they have discussed the situation with their healthcare provider.

Rashes — Several different types of rashes can appear while people are taking penicillin. Rashes that involve hives (raised, intensely itchy spots that come and go over hours, show picture 1) suggest a true allergy.

However, some people, especially young children, can develop flat, blotchy rashes that spread over days but do not change by the hour (show picture 2). These rashes typically start after several days of treatment. This type of rash is less likely to indicate a dangerous allergy, although it can be difficult to distinguish between different types of rashes that occurred in the past. Taking a photograph of a rash is always helpful.

Allergic reactions — An allergic reaction occurs when the immune system begins to recognize a drug as something "foreign". Several different symptoms can indicate that a person is allergic to penicillin. These include hives (raised, intensely itchy spots that come and go over hours) (show picture 1), angioedema (swelling of the tissue under the skin, commonly around the face), wheezing and coughing from asthma-like reactions (narrowing of the airways into the lungs).

A past history of these types of reactions is important because the person might develop a more severe reaction, such as anaphylaxis, if they were to take the antibiotic again. Mild to moderate allergic reactions to penicillins are common, occurring in 1 to 5 percent of people.

Anaphylaxis — Anaphylaxis is a sudden, potentially life-threatening allergic reaction. Symptoms include those of an allergic reaction, as well as very low blood pressure, difficulty breathing, abdominal pain, swelling of the throat or tongue, and/or diarrhea or vomiting. Fortunately, anaphylaxis is uncommon. (See "Patient information: Anaphylaxis symptoms and diagnosis").

PENICILLIN ALLERGY TESTING — In some situations, it is necessary to determine with certainty if a person is allergic to penicillin. Testing for allergy is recommended in the following situations: People who have a suspected penicillin (or closely related antibiotic) allergy and require penicillin to treat a life-threatening condition for which no alternate antibiotic is appropriate. People who have frequent infections but have suspected allergies to many antibiotics, leaving few options for treatment. Penicillin skin testing is suggested for anyone with a history of penicillin allergy (when penicillin skin test solutions become commercially available again). Because 90 percent of people will test negative, this type of evaluation can decrease medical costs and reduce the use of unnecessarily strong (ie, broad-spectrum) antibiotics.

Penicillin skin testing does not provide any information about certain types of reactions. This includes anyone who has experienced a severe reaction with extensive blistering and peeling of the skin (Stevens-Johnson syndrome or toxic epidermal necrolysis), a widespread sunburn-like reaction that later peeled (erythroderma), or a rash composed of small bulls-eyes or target-like spots (erythema multiforme),
People with these types of reactions should never again be given the medication that caused the reaction. This applies to all situations since a second exposure could cause a severe progressive reaction and even death.

Skin testing — Skin testing is the most reliable method to determine the risk of a serious, sudden onset allergic reaction in a person with a history of allergy to penicillin.

Several different types of penicillin preparations are required for skin testing. These preparations can be manufactured commercially but are not currently available in the United States. Thus, the most reliable type of skin testing for penicillin allergy cannot be performed in the United States at this time. It is expected that the preparations will be available again within the next 12 to 24 months.

Until skin tests are available, options for people who may be allergic to penicillin include: Take an different antibiotic Undergo a challenge test (See "Challenge testing" below) Undergo desensitization (See "Penicillin desensitization" below)

Skin testing procedure — Skin testing should be done by an allergist in an office or hospital setting. Testing usually takes less than one hour to complete. The skin is pricked with weak solutions of the various preparations of penicillin and observed for a reaction. This may cause discomfort due to itching, but it is not painful. If there is no skin reaction, slightly stronger solutions are then used.

A positive skin reaction is an itchy, red bump that lasts about half an hour and then resolves. The testing is stopped if a skin reaction occurs since this indicates that the person is truly allergic.

If the patient completes the skin testing without a positive reaction, a single oral dose of full strength penicillin is commonly given. This confirms that the patient does not have an allergy to the medication. The oral dose is given since there is a very small risk of false negative results (when the skin test is negative although the person is actually allergic).

Interpreting results — Medical tests, including skin testing, are rarely 100 percent accurate. Most people with a positive penicillin skin test will experience an allergic reaction if given penicillin or a related antibiotic (as would be expected). However, 3 percent or less of people with a history of penicillin allergy and a negative skin test will experience an allergic reaction. These reactions are always mild, and anaphylaxis in this situation is rare.

If a person has a negative skin test and has no reaction to an oral dose of the antibiotic, no future precautions are necessary.

Challenge testing — Because skin testing is not currently available in many places, a healthcare provider may recommend a challenge test. However, this is only recommended if the person requires penicillin, no other antibiotic is available, and the chances of a true allergy are small (eg, last reaction was at least 10 years ago or allergic reaction symptoms not likely caused by true allergy). If the chances of a true allergy are high, desensitization is generally recommended.

Challenge testing is usually done in an office setting, starting with a very small dose of the antibiotic given by mouth. If the person tolerates the smallest dose, a larger dose is given every 30 to 60 minutes until he/she has signs of an allergic reaction or the full dose is given. If the person tolerates the full dose, he or she is not allergic to the antibiotic.

PENICILLIN DESENSITIZATION — Desensitization can be done for people who are truly allergic to penicillin but require treatment with it or a closely related antibiotic. Desensitization refers to a process of giving a medication in a controlled and gradual manner, which allows the person to tolerate it temporarily without an allergic reaction.

Technique — Desensitization can be performed with oral or intravenous medications, but should always be performed by an allergy specialist. There are different techniques for desensitization. Some patients undergo desensitization in an outpatient clinic under supervision while others are treated in an intensive care unit.

Limitations — While usually successful, desensitization has two important limitations. Desensitization does not work and must never be attempted for certain types of reactions (Stevens-Johnson syndrome, toxic epidermal necrolysis, erythroderma, and erythema multiforme). Desensitization also does not work for other types of immunologic reactions to antibiotics, such as serum sickness, drug fever, or hemolytic anemia. Desensitization is temporary. A person is unlikely to have an allergic reaction to the medication during treatment, after undergoing desensitization, as long as the antibiotic is taken regularly. However, once the antibiotic is stopped for more than 24 hours (times differ slightly for different medications), the person is again at risk for a sudden allergic reaction. Repeat desensitization is required if the same medication is needed again.

OTHER ANTIBIOTIC ALLERGIES — Reliable skin tests are not commercially available for some antibiotics. Thus, determining if a person has an allergy to these antibiotics is more difficult, and is mostly based on the history of the reaction. Skin testing with other antibiotics is sometimes performed, but the results are much less certain than those of penicillin testing.

Cephalosporins — Cephalosporins are a class of antibiotics closely related to penicillin. There are a number of cephalosporin medications available, a few of which include cephalexin (Keflex®), cefaclor (Ceclor®), cefuroxime (Ceftin®), cefadroxil (Duricef®) , cephradine (Velocef®). cefprozil (Cefzil®), loracarbef (Lorabid®), ceftibuten (Cedax®), cefdinir (Omnicef®), cefditoren (Spectracef®), cefpodoxime (Vantin®) and cefixime (Suprax®).

People with a history of penicillin allergy have a small risk of having an allergic reaction to cephalosporins. If possible, penicillin skin testing should be performed in these individuals. Since testing will be negative in about 90 percent of these people, a negative test will allow them to take cephalosporins safely. People with a positive skin test to penicillin have a small risk of an allergic reaction to cephalosporins and may require more caution in terms of how the cephalosporin is administered.

Allergic reactions to cephalosporins are less common than reactions to penicillin. In addition, skin testing to evaluate cephalosporin allergy is not as accurate as penicillin skin testing. If a cephalosporin is required, then there are several options: Take an different antibiotic Undergo a challenge test (See "Challenge testing" above) Undergo desensitization (See "Penicillin desensitization" above)
