What Sulfamethoxazole/trimethoprim is

Two antibiotics in one pill, a sulfa drug and trimethoprim. Together they block bacteria from making folate, which they need to grow.

What it’s for

Bladder infections, skin infections including MRSA boils, and some gut and lung infections.

How it’s taken

By mouth, usually twice a day for 3 to 14 days, with a full glass of water.

Good to know

Don’t take it with a sulfa allergy. Rarely it causes a severe skin reaction: blistering, peeling or a rash with mouth sores needs emergency care. It can raise potassium and boosts the effect of warfarin. It’s usually avoided late in pregnancy.
