Is meloxicam a sulfa drug?

Medically reviewed by Drugs.com. Last updated on April 7, 2022.

I took one 7.5mg meloxicam and had severe abdominal cramps and pain. Is this a sulfa drug? I have an allergic reaction to Macrobid which I believe is a sulfa drug. I took the meloxicam with food as suggested an was up all night with bad pain. I am trying to figure out if I had an allergic reaction or the drug is just hard on the intestines?

Meloxicam does contain sulfa, although not the typical sulfonamide structure which typically occurs in those with sulfa allergies.
If you are experiencing unwanted side effects, the best thing is to see your doctor.
