Sulfamethoxazole/Trimethoprim 200/40 mg Bactrim – Antibiotic

Bactrim 200/40 mg – Sulfamethoxazole/Trimethoprim

Bactrim 200/40 mg contains two antibacterial active ingredients, sulfamethoxazole and trimethoprim. Together, these medicines are known as co-trimoxazole and work by interfering with different stages of bacterial folate metabolism. This combined action helps prevent susceptible bacteria from producing substances they need for growth and reproduction.

Bactrim may be prescribed by a healthcare professional for certain bacterial infections when the responsible bacteria are susceptible to the medicine. It is not effective against viral infections such as the common cold or influenza.

Key Benefits

• Contains two complementary antibacterial ingredients.
• Works against certain susceptible bacteria.
• Interferes with bacterial folate metabolism.
• May be prescribed for selected bacterial infections.
• Available as an oral tablet formulation.

How It Works

Sulfamethoxazole and trimethoprim act at different points in the bacterial folate pathway. By blocking this pathway, the combination limits the bacteria's ability to make essential components required for growth and reproduction.

How to Use

Take Bactrim exactly as directed by your doctor or pharmacist. The appropriate dose and duration depend on the type and severity of infection, age, kidney function, and other individual factors.

Take the medicine with sufficient water and follow the prescribed treatment schedule. Do not change the dose or stop treatment early without professional advice.

Possible Side Effects

Seek medical attention promptly if you develop a severe skin reaction, difficulty breathing, swelling of the face or throat, unusual bruising, severe diarrhea, or other serious symptoms.

Precautions

Tell your healthcare professional if you have a history of allergy to sulfonamide medicines or trimethoprim, kidney or liver problems, blood disorders, or if you take other medicines.

Bactrim can interact with certain medications, so provide your doctor or pharmacist with a complete list of medicines and supplements you use.
