Bactrim and Septra (co-trimoxazole, a combination of sulfamethoxazole and trimethoprim) are antibiotics used in multiple sclerosis for urinary tract infections treatment and prevention.1

Bactrim treats different types of infection caused by bacteria. Due to their established effectiveness, low cost, and relative lack of toxicity, this group of antibiotics (sulfonamides) remains a first choice drug for conventional treatment of acute, uncomplicated urinary tract infections caused by susceptible organisms.

The recommended oral dose (tablets, suspension) of Bactrim for mild to moderate infections is 2 grams initially, followed by 1 gram twice daily. For severe infections, the recommended dose is 2 grams initially, followed by 1 gram three times a day.

These types of medications must be used for the full prescribed length of time, even if the symptoms improve before the infection has completely cleared.

Common Bactrim side effects include nausea, vomiting, loss of appetite, and mild itching or rash.

There are generics available rather than the brand-name drugs.
