Penicillin allergy what other antibiotics to avoid

Why is there this discrepancy? One reason is that having an infection, such as a freezing or cough, can be a common trigger for developing hives. If you developed hives while taking penicillin for an illness it can be hard to determine whether the trigger is due to an allergy to penicillin or due to the illness itself. Another reason is that people often error side effects of amoxicillin, such as nausea or diarrhea  for symptoms of an allergic reaction. Finally, 80% of patients with true penicillin allergy lose their sensitivity after 10 years.

If an adult was told to always avoid penicillin due to a reaction in childhood, it is likely the allergy is no longer present.


Important information

Do not use this medication if you are allergic to penicillin V or to any other penicillin antibiotic, such as amoxicillin (Amoxil), ampicillin (Omnipen, Principen), carbenicillin (Geocillin), dicloxacillin (Dycill, Dynapen), or oxacillin (Bactocill).

Before using penicillin V, tell your doctor if you are allergic to cephalosporins such as Ceclor, Ceftin, Duricef, Keflex, and others, or if you own asthma, kidney disease, a bleeding or blood clotting disorder, a history of diarrhea caused by taking antibiotics, or a history of any type of allergy.

Penicillin V can make birth control pills less effective, which may result in pregnancy.

Before taking this medicine, tell your doctor if you use birth control pills. Take penicillin V for the entire length of time prescribed by your doctor. Your symptoms may get better before the infection is completely treated.

Penicillin V will not treat a viral infection such as the common freezing or flu. Do not give this medication to another person, even if they own the same symptoms you do.

Antibiotic medicines can cause diarrhea, which may be a sign of a new infection. If you own diarrhea that is watery or has blood in it, call your doctor. Do not use any medicine to stop the diarrhea unless your doctor has told you to.


Antibiotic allergic reactions

Around 1 in 15 people own an allergic reaction to antibiotics, especially penicillin and cephalosporins.

Penicillin allergy what other antibiotics to avoid

In most cases, the allergic reaction is mild to moderate and can take the form of:

  1. coughing
  2. wheezing
  3. a raised, itchy skin rash (urticaria, or hives)
  4. tightness of the throat, which can cause breathing difficulties

These mild to moderate allergic reactions can generally be successfully treated by taking antihistamines.

But if you’re concerned, or your symptoms don’t get better with treatment, call your GP for advice. If you cannot contact your GP, call NHS 111.

In rare cases, an antibiotic can cause a severe and potentially life-threatening allergic reaction known as anaphylaxis.

Initial symptoms of anaphylaxis are often the same as a mild allergic reaction.

They include:

  1. a quick heartbeat
  2. confusion and anxiety
  3. clammy skin
  4. feeling lightheaded or faint 
  5. wheezing
  6. breathing difficulties – such as quick, shallow breathing
  7. collapsing or losing consciousness

There may be other allergy symptoms, including an itchy, raised rash (hives), feeling or being ill, swelling (angioedema), or stomach pain.

Anaphylaxis is a medical emergency and can be life-threatening.

Dial 999 immediately and enquire for an ambulance if you ponder you or someone around you is experiencing anaphylaxis.

“We used to tell nine out of 10 people who report a penicillin allergy are skin-test negative. Now it looks more love 19 out of 20,” said Dr. David Lang, president-elect of the American Academy of Allergy, Asthma and Immunology and chairman of allergy and immunology in the respiratory institute at the Cleveland Clinic.

Patients can get mislabeled as allergic to penicillin in a number of diverse ways.

They may experience bad drug reactions love headaches, nausea or diarrhea, which are not true allergic reactions but are misinterpreted. Alternatively, they may develop a symptom love a rash, which is indicative of a genuine allergic reaction but could be caused by an underlying illness and not by the drug.

And numerous people who own avoided penicillin for a decade or more after a true, severe allergic reaction will not experience that reaction again. “Even for those with true allergy, it can wane,” said Dr. Kimberly Blumenthal, the review’s senior author, who is an allergist and an assistant professor at Harvard Medical School.

“We don’t really understand this, but once you’ve proven you’re tolerant, you go back to having the same risk as someone who never had an allergy” to penicillin.

It’s a excellent thought to discover out if your allergy is genuine or not because penicillin antibiotics, which are part of a group of drugs called beta-lactam antibiotics, are among the safest and most effective treatments for numerous infections. Beta-lactams are the treatment of choice for Group A Streptococcus, which can cause pneumonia, toxic shock and other syndromes; Group B Strep, which causes meningitis; Staphylococcus aureus and other pathogens. Beta-lactams are used prophylactically to prevent infections during surgery, and studies own found that patients with penicillin allergies who are given second-line antibiotics before surgery had a substantially greater risk of a surgical site infection.

Beta-lactams are also the first line treatment for syphilis and gonorrhea.

Substitutes love fluoroquinolones, clindamycin, vancomycin and third-generation cephalosporins are available, but they are often both less effective and more expensive, and numerous are broader spectrum antibiotics, which can lead to the development of resistant organisms and other side effects, experts tell. Studies own shown that patients with penicillin allergies are at increased risk for developing serious infections love Clostridium difficile, methicillin-resistant Staphylococcus aureus (MRSA), and vancomycin-resistant enterococcus.

Don’t challenge yourself to penicillin on your own, experts warn.

Patients who own been told they’re allergic to penicillin should talk to their doctors, who should take a careful history and review the symptoms of the reaction.

If the past reaction to penicillin included symptoms love headache, nausea, vomiting and itching, or the diagnosis was made based on a family history of the allergy, the patient is considered low risk and may be capable to take a first dose of penicillin or a related antibiotic, such as amoxicillin, under medical observation.

If the past reaction included hives, a rash, swelling or shortness of breath, patients should own penicillin skin testing, which involves a skin prick test using a little quantity of penicillin reagent, followed by a second test that places the reagent under the skin if the first test is negative.

If both tests are negative, the patient is unlikely to be allergic to penicillin, and an oral dose may be given under observation to confirm.

Keep this medication in the container it came in, tightly closed, and out of reach of children.

Penicillin allergy what other antibiotics to avoid

Store the tablets at room temperature and away from excess heat and moisture (not in the bathroom). Hold the oral solution in the refrigerator, tightly closed, and dispose of any unused medication after 14 days. Do not freeze it.

It is significant to hold every medication out of sight and reach of children as numerous containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately put the medication in a safe location – one that is up and away and out of their sight and reach.

Up and Away

Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication below the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to study about take-back programs in your community. See the FDA’s Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not own access to a take-back program.

No large deal, right?

What is the large deal if one has a possible penicillin allergy? There are numerous other antibiotics out there, right?

Unnecessarily avoiding penicillin could actually cause more harm than you would ponder. Broad-spectrum antibiotics are often used as alternatives to penicilllins. These antibiotics are typically more expensive, are more likely to cause significant side effects, and can increase the risk of antibiotic resistant infections.

Your provider at Colorado Allergy and Asthma Centers will assess your history of reaction to penicillin and if appropriate, order penicillin skin testing and oral challenge to determine if you are indeed allergic or if you are capable to safely take this medication in the future. Book your appointment today!
