What causes an antibiotic allergy?

What causes an antibiotic allergy?

Immune activation: The body recognizes foreign substances as invaders at time and will immunologically react against them. Antibiotics, especially in certain categories, will unite with bodily chemicals and become more likely to generate an immune response. When this happens, an allergy sets up. This would only be annoying except the reaction can be extreme and even shut down the lungs. ...Read more

I was diagnosed with an antibiotic allergies at a young age. Recent testing failed to prove if I'm really allergic. Can an oral challenge test help?

I was diagnosed with an antibiotic allergies at a young age. Recent testing failed to prove if I'm really allergic. Can an oral challenge test help?

Drug allergy: Most of the time there is no true allergy to a certain drug, rather an adverse drug reaction interpreted as an allergy, yet we cannot speculate. I'm not sure what kind of allergy testing you had that failed, and why do you want to go for an oral challenge if there is a safer antibiotic alternative that you aren't allergic to. If necessary, consult an allergist, check aaaai. Org for one in your area ...Read more

Can you test for antibiotic allergies?

Yes.: Yes, however it is somewhat limited. The only fda approved antibiotic that we can skin test for is penicillin. It is tested in small amounts by scratch testing and then small amounts are injected, in increasing doses. Finally if these are negative a small oral dose is given. It is important to test for possible pencillin allergy as this is still an effective, inexpensive antibiotic. ...Read more

Antibiotics allergies are how common?

Tricky question: Not as often as people think. Studies have shown that up to 80% of people reporting a medication allergy and not actually allergic to that medicine. Often with antibiotics the rash is actually due to the underlying infection being targeted with medication and not the medication itself. Talk to an allergist. ...Read more

Coughing green yellow mucus for months. Saliva very thick. Have had all tests done. Normal pft. Been on antibiotics. Allergy test fine. What is it?

Complex problem: Your problem is rather complex that needs a thorough evaluation and examination to see what it is. Based on limited data that you provide, chronic cough with colored mucus may be associated with either chronic bronchitis or chronic sinusitis. A normal pft is normal if it is read by an allergy/asthma or lung specialist. Only about 60% of chronic sinusitis associated with allergy. ...Read more

Will an antibiotic allergy go away on its own? I got hives from Hydrochlorothiazide on my face & chest. I've been using Benadryl (diphenhydramine) & water gels for pain

Will an antibiotic allergy go away on its own? I got hives from Hydrochlorothiazide on my face & chest. I've been using Benadryl (diphenhydramine) & water gels for pain

Yes: But the time it takes for remission to occur (if it goes away at all) depends on the medication. People with sulfa allergy almost never loses the allergy but those with penicillin allergy tend to lose it in 5-6 years. Do note that hydrochlorothiazide is not a common allergen and you should consider seeing an allergist to document this allergy. Benadryl (diphenhydramine) gel for pain? Does it work? ...Read more

My doctor prescribed antibiotics for allergy-caused tonsilitis. Is that okay?

My doctor prescribed antibiotics for allergy-caused tonsilitis. Is that okay?

Not really: Allergy symptoms will not improve with antibiotics. If a person has tonsillitis, it is helpful to have a throat culture to determine if a bacterial infection (like strep) is present, then antibiotics would be appropriate. While there is generally low risk with most antibiotics, inappropriate use can lead to resistant bacteria, side effects and even drug reactions. ...Read more
