Sulfamethoxazole/Trimethoprim

Product Overview

Co-Trimoxazole is a combination antibiotic medication containing Sulfamethoxazole and Trimethoprim as active ingredients. Available in tablet form, this dual-action antibiotic works by preventing the growth of bacteria that cause various infections. It is commonly prescribed for treating urinary tract infections, respiratory infections, middle ear infections, traveler’s diarrhea, and specific pneumonia types.

Uses

This medication is effective against numerous bacterial infections caused by susceptible strains, including Escherichia coli, Haemophilus influenzae, Staphylococcus aureus, and Streptococcus pneumoniae. While it treats bacterial infections effectively, it’s important to note that Co-Trimoxazole doesn’t work against viral infections like colds or flu.

How to Use

Take Co-Trimoxazole tablets whole with a full glass of water, preferably with food or milk to minimize stomach upset. Follow your doctor’s prescribed dosage, typically one or two tablets every 12 hours for the recommended treatment duration. Never crush or chew the tablets. If you miss a dose, take it when remembered unless it’s nearly time for the next dose – in which case skip the missed dose.

How it Works

The medication works through a dual mechanism, blocking two key enzymes (dihydropteroate synthetase and dihydrofolate reductase) in bacterial folate production. This disruption of folic acid synthesis prevents bacterial growth and reproduction, effectively eliminating susceptible bacterial infections.

Dosage and Administration

Dosage varies based on infection type/severity, patient age, weight, and kidney function. Always follow your doctor’s specific instructions. Never exceed prescribed doses or treatment duration without medical advice. Your doctor may conduct bacterial tests to determine the most effective antibiotic treatment.

Warnings

Inform your doctor about all medical conditions, allergies, and current medications before use. Co-Trimoxazole may interact with blood thinners, diuretics, and other antibiotics. Use cautiously in patients with kidney/liver impairment or folate deficiency. Avoid during pregnancy/breastfeeding and in infants unless specifically prescribed.
