Uses

USES: Trimethoprim is an antibiotic used to treat bacterial infections. It works by stopping the growth of bacteria. This antibiotic treats only bacterial infections.

How to use TRIMETHOPRIM SOLUTION - ORAL

HOW TO USE: Measure the dose out carefully with a medication spoon/cup. Take this medication by mouth on an empty stomach at least 1 hour before or 2 hours after a meal as directed by your doctor. It may be taken with food if stomach upset occurs. Dosage is based on your medical condition and response to therapy. For the best effect, take this antibiotic at evenly spaced times. To help you remember, take this medication at the same time(s) every day. Continue to take this medication until the full prescribed amount is finished, even if symptoms disappear after a few days. Stopping the medication too early may allow bacteria to continue to grow, which may result in a relapse of the infection. Inform your doctor if your condition persists or worsens after several days.
