  • Overview

    What is Trimethoprim?

    Trimethoprim is a course of antibiotic tablets designed to alleviate the symptoms of cystitis to eventually clear the infection completely. Many people find symptoms significantly lessening within three days and clearing completely by the end of the course. Trimethoprim can be used for many bacterial infections but it's most popular use is for UTIs, in particular cystitis.

  • How does Trimethoprim work?

    Being an antibiotic, Trimethoprim can treat and cure bacterial infections such as cystitis. It works by hindering the production of folic acid (folate) so the bacteria cannot replicate its DNA and multiply. By stopping this progress, Trimethoprim halts the spread of infection, allowing your immune system to take over, killing the bacteria.

  • How do I use Trimethoprim?

    For uncomplicated lower urinary tract infection (cystitis) you must take ONE tablet twice daily for 3 days.

    • All tablets to be taken with water, with or without food

    If you forget a pill, take it as soon as you remember unless it is near to your next dose. If this is the case, miss completely and continue to finish the dosage. Never take a double dose to make up for a missed pill.
