Can bactrim cause vomiting?

Started taking Bactrim tablets a couple of days ago for a UTI. Today, after lunch, I felt really sick and ended up throwing up. Does this medicine cause vomiting, or should I be worried about something else?

Yes, Bactrim can be very harsh on an empty stomach and cause vomiting. I suggest eating a simple, non-spicy meal like khichdi before taking it, but if you still throw up, you must talk to your doctor about alternative treatments.

When my father was prescribed this at the hospital, the doctor clearly warned us about vomiting as a side effect. You should call your doctor and ask if you need to stop the medicine or if they can add an anti-vomiting tablet.

Vomiting from a medicine will dehydrate you quickly and ruin your workout recovery. If you are on Bactrim and throwing up, stop exercising, rest, and consult your doctor immediately to get hydrated and change the medicine.

Ah, the wonders of modern medicine where the cure makes you feel worse than the disease! Bactrim definitely made me vomit back in the day. Don't play hero, call your doctor and get a medicine that actually stays in your stomach.

I can only share what happened to me, but Bactrim made me severely nauseous and I threw up within an hour of taking it. My doctor had to stop it and give me a different antibiotic. It is best to contact your healthcare provider.

Bactrim is a very affordable medicine, but if it causes vomiting, you might end up paying more for doctor visits and IV fluids due to dehydration. It is practical to call your clinic early and ask for a suitable, affordable alternative.

Bro, yes! I was prescribed Bactrim for a skin issue and I threw up twice on the very first day. It is super strong. I had to call my clinic and they changed the prescription instantly, so don't just suffer through it.
