What is the dosage and how should it be used?
Trimethoprim comes as an oral tablet and solution.
The usual dose is 100 mg every 12 hours or 200 mg every 24 hours for 10 days. As with all antibiotics, it is important to complete the entire course of trimethoprim even if your symptoms start to improve before the infection is completely treated.
Persons with kidney diseases may need to receive lower doses. (Diseased kidneys may not eliminate trimethoprim adequately from the body, and levels of trimethoprim may increase in the body and lead to side effects.)
Take this drug exactly as directed by your physician. If you do not understand these instructions, ask your pharmacist, nurse, or doctor to explain them to you.
Trimethoprim may be taken with or without food, and preferably with a full glass of water.
