I am allergic to penicillin G per the blood test. Augmentin (amoxicillin and clavulanate) caused the reaction. Is Augmentin (amoxicillin and clavulanate) , penicillin "G" ? Ty

Similar: The amoxicillin in Augmentin (amoxicillin and clavulanate) and Penicillin share a common core structure and thus people allergic to Penicillin are almost always allergic to amoxicillin. On the other hand, not all people reacting to amoxicillin are allergic to penicillin when the reaction is a skin rash. ...Read more

Very allergic to sulfa drugs, took 1 Bactrim (sulfamethoxazole and trimethoprim) 800 in error. What should I do?

Very allergic to sulfa drugs, took 1 Bactrim (sulfamethoxazole and trimethoprim) 800 in error. What should I do?

Antihistamine helps: In such a situation, one can take antihistamines such as Benadryl, (diphenhydramine) Claritin, Allegra, or Zyrtec (all over-the-counter) and call her primary care doctor. What the doctor might do will likely depend on the type of reaction the patient has had in the past, how severe the reaction was, how fast the reaction happened, etc... Immediate, severe allergic reactions require an injection (EpiPen) and 911. ...Read more

Took IV rocephin (ceftriaxone) and was ok, on 3rd day dosage raised, broke out in rash. Did high dosage cause reaction or just allergy in general? 38 F

Took IV rocephin (ceftriaxone) and was ok, on 3rd day dosage raised, broke out in rash. Did high dosage cause reaction or just allergy in general? 38 F

Either is possible: rashes from antibiotics can occur even after you have taken it before. Did you just have a rash, or did you get fever and or hives too? Did you feel any shortness of breath? It is very possible that it was only the higher dose that triggered the reaction. The only way to tell is to cautiously try it again, but you should discuss with your doctor so s/he is fully aware and can gage the risk to y ...Read more

Allergic to pcn since a baby. Use ees (erythromycin ethyl succinate) instead.?

Yes: Macrolide antibiotics like ees (erythromycin ethyl succinate) will be safe. But if your allergic reaction was some time ago, you may want to consider seeing an allergist for pcn testing. Skin testing is now very accurate. You may have outgrown your pcn allergy, or may have even been misdiagnosed, which happens often. ...Read more

With Cefzil & rocephin (ceftriaxone) I get hives.Should I take penicillin shot for syphilis treatment.This is a 3rd infection. Used doxycycline for first 2.

With Cefzil & rocephin (ceftriaxone) I get hives.Should I take penicillin shot for syphilis treatment.This is a 3rd infection. Used doxycycline for first 2.

Condoned: Penicillin is still the first line treatment for syphilis. The most effective treatment for syphilis is not to get it, use a condom. The more often you get it, the greater your risk for antibiotic resistance. Also, with this being your third episode, you are now at high risk of contracting chlamydia and HIV. You need to get tested for those too. Stop playing Russian roulette with your life. ...Read more

Yes: If you feel you still need it, but don't exceed recommended daily dose for diphenhydramine from all sources (300 mg /day), depends on the reaction too was it a local or whole body reaction? keep taking the benadryl for the next 24 -48 hours every 4-6 hours as needed 25- 50 mg , don't drive, and take the medicines prescribed at ER, if it was a whole body reaction, see an allergist, take care ...Read more

I have anaphylaxis from Benadryl (diphenhydramine) (documented by ED mds), is chlor trimeton ok to take instead?

I have anaphylaxis from Benadryl (diphenhydramine) (documented by ED mds), is chlor trimeton ok to take instead?

No guarantee: Chlortimeton is a different chemical compared to benadryl (diphenhydramine) (Alkylamine vs Ethanolamine derivatives) so in theory it should be ok.Actual anaphylaxis reaction to antihistamines is not only rare, but every case report, there have been other drugs involved (co-ingested). Consider specific allergy testing because anaphylaxis is life-threatening and if it wasn't the benadryl (diphenhydramine) you need to know absolutely. ...Read more

Was tested with GO in Sept. Prescribed 2x Cefixime 200mg & 2x Zithromax 500mg. In Dec, still tested +tive. Can i still take them at an increased dose?

Go to ID doctor: Persistent infection after treatment may be due to reinfection or resistance/treatment failure. Make sure parter(s) are treated. If the cultures for gonococcus are positive, isolates should be submitted for resistance testing. Advise IM ceftriaxone plus high dose oral Azithromycin. Gemifloxacin or IM gentamicin if resistance to cephalosporins is suspected. Retest 14 days after retreatment. ...Read more

I'm allergic to Erythromycin-anaphylaxis 
Clindamycin- anaphylaxis
Bactrim- rash
Sulfa drugs- rash can I use polymyxin b sulfate eye drops?

Yes: Polymyxin is an effective anti-bacterial. You could use it without the allergies popping up as it has with others. However: are you sure you need this drop? It seems as if you are using an antibiotic for every eye inflammation, most of which are probably not bacterial. And in so doing you have sensitized yourself to antibiotics that you might need for an actual infection. ...Read more

Help please! is epipen (epinephrine) jr auto injectors used for all allergic reactions or just emergency reactions?

Help please! is epipen (epinephrine) jr auto injectors used for all allergic reactions or just emergency reactions?

Limited use: The value of an Epipen (epinephrine) is its ability to help block a tragic evolving allergic reaction and provide time for a person to reach urgent followup care.It's effect is relatively short (hour or so).If you simply break out in hives as a food reaction, it could help some, but since the food will be processed in your body for days, a longer agent like Diphenhydramine or citirazine would be more benificial. ...Read more
