I am not aware of a drug called arthromycin. (I am a licensed pharmacist, so if it existed, I would know.) Do you mean azithromycin (brand name Zithromax) or erythromycin? Neither of those drugs contain "sulfa". If you have a sulfa allergy, you will be fine with these medications.
yes, it is a sulpha drug
yes, they belong to different classes of drugs
Per my pharmacist, no it is not a sulfa drug!
Is Cosopt eye drops a sulfa drug
Penicillin is not a sulfa drug.
Nope. Acyclovir is an antiviral drug. Sulfas are antibiotics.
No
For anyone who is has a sulfa allergy, it is important to know which prescription or non-prescription medications are sulfa-based. If you are suffering from any type of bacterial infection, be sure to tell your doctor about your allergy. The reason is that one of the popular options, the Zithromax z-pak, is sulfa-based and may cause a severe allergic reaction.
yes
No
Celebrex is not a sulfa drug, it a NSAID or a non-steroidal anti-inflammatory drug. It is used to treat pain from arthritis and menstrual cramps.
no, sulfate is a salt, like a prefix to a word (like "ed" or "ing") sulfa is short for sulfonamide antimicrobials
cranberries do contain sulfa. Sulfa is used in anti-biotics. Cranberry juice contains sulfa which is also a drug used in the manufacture of anti-biotics
