Trimethoprim

Trimethoprim is an antibiotic medication primarily used to treat bacterial infections. It works by inhibiting the production of folic acid in bacteria, which is essential for their growth and reproduction. This action helps to stop the spread of the infection in the body. Trimethoprim is commonly used to treat urinary tract infections (UTIs), bronchitis, and other bacterial infections. It is often used alone or in combination with other antibiotics for more comprehensive treatment. It is important to use Trimethoprim exactly as prescribed by a healthcare provider to ensure its effectiveness.

Uses of Trimethoprim

• Treats urinary tract infections (UTIs)
• Helps manage bronchitis and other respiratory tract infections
• Treats ear infections caused by susceptible bacteria
• Effective in treating traveler's diarrhea caused by bacteria
• Used to prevent and treat Pneumocystis jirovecii pneumonia in immunocompromised patients

How Trimethoprim Works

Trimethoprim works by blocking the enzyme dihydrofolate reductase, which is necessary for bacteria to produce folic acid. Folic acid is crucial for bacterial DNA synthesis and cell division. By inhibiting this process, Trimethoprim prevents the bacteria from multiplying and spreading, helping to clear the infection. This selective action against bacteria makes Trimethoprim effective in treating a variety of bacterial infections.

Benefits of Trimethoprim

Trimethoprim is typically taken orally in tablet or liquid form. The dosage and duration of treatment depend on the type and severity of the infection. It is important to complete the entire course of treatment as prescribed by your healthcare provider, even if symptoms improve before the medication is finished.

If you miss a dose, take it as soon as you remember, but skip the missed dose if it's almost time for the next one. Do not double the dose to make up for a missed one.
