Description
What Is Trimethoprim?
Trimethoprim is an antibiotic used to treat bladder cystitis and urinary tract infections (UTIs). The drug helps relieve the burning pain, itching, and discomfort that comes with UTIs. Trimethoprim helps women, who are more prone to UTIs than men, to manage their symptoms. It is advisable to maintain cleanliness and sexual hygiene to prevent UTIs from recurring. Taking a three-day course of Trimethoprim will clear most bladder and urinary tract infections. Trimethoprim is recommended where nitrofurantoin is unsuitable for treating cystitis due to side effects.
How Does Trimethoprim Work?
Most cystitis originates from the gut, known as E.coli. Trimethoprim does not kill E.coli. It works by stopping bacterial DNA synthesis, meaning that the bacteria cannot replicate. This allows your immune system to destroy the infecting bacteria until they get eradicated and your infection gets resolved. The bacteria gets out of the body through the urinary tract when urinating. Symptoms including high temperatures and pain improve with 24-48 hours of taking Trimethoprim. However, you should complete the entire course to avoid bacterial resistance to the drug.

- You are allergic to Trimethoprim.
