Bactrim: Uses, Dosages, and Side Effects
Bactrim is a widely used antibiotic medication known for its effectiveness in treating a variety of bacterial infections. It is a combination of two antibiotics, sulfamethoxazole and trimethoprim, which work together to inhibit the growth of bacteria.
What is Bactrim?
Bactrim is a prescription antibiotic used to treat different types of bacterial infections such as urinary tract infections, respiratory infections, and certain types of diarrhea. It works by preventing bacteria from producing the folic acid they need to grow and multiply.
Mechanism of Action
The combination of sulfamethoxazole and trimethoprim in Bactrim works synergistically to block two consecutive steps in bacterial folic acid synthesis. This dual action makes Bactrim particularly effective against a wide range of bacteria.
Indications for Use
Bactrim is commonly prescribed for:
– Urinary Tract Infections (UTIs)
– Pneumocystis jiroveci pneumonia
– Traveler’s diarrhea
– Shigellosis
– Acute exacerbations of chronic bronchitis
Dosage and Administration
The dosage of Bactrim varies depending on the type and severity of the infection, as well as the patient’s age and kidney function. It’s essential to follow the doctor’s prescription exactly. Here’s a general guideline:
| Condition | Dosage |
|---|---|
| Adults | 1 Bactrim DS (double strength) tablet every 12 hours |
| Children | Based on body weight, typically 40 mg/kg of sulfamethoxazole and 8 mg/kg of trimethoprim per day, divided into two doses |
Always take Bactrim with a full glass of water and maintain hydration throughout the treatment to prevent kidney stones.

Like all medications, Bactrim can cause side effects, although not everyone experiences them. Common side effects include:
