What SEPTRIN is used for
SEPTRIN is used for the treatment of a variety of bacterial infections, including bronchitis and infections of the ear, sinus, kidney, bladder, stomach, bowel, skin and wounds.
Trimethoprim and sulfamethoxazole (the active ingredients in SEPTRIN) belong to a group of medicines called "anti-infectives". They work in slightly different ways to stop the growth of bacteria causing the infection.
If you have any questions about why you are taking SEPTRIN, ask your doctor or pharmacist. Your doctor may have prescribed it for another reason.
There is no evidence that this medicine is addictive.
SERENACE is only available with a doctor’s prescription.
