Indications & Uses
Pharmacology
Cotrimoxazole is a broad-spectrum bactericidal agent effective against a wide range of gram-positive and gram-negative bacteria, as well as some protozoa. It combines Trimethoprim and Sulphamethoxazole in a 1:5 ratio, which together produce their bactericidal effect by sequentially blocking two bacterial enzyme systems involved in the microorganism's biosynthesis of folinic acid.

Side Effects
Sulphamethoxazole-Trimethoprim is generally well tolerated. Rare but reported side effects include crystalluria, allergic reactions, haemolysis, thrombocytopenia, neutropenia, and agranulocytosis. Milder effects such as malaise, headache, nausea, and vomiting may occur, but these are usually temporary and do not usually call for stopping treatment.
Cautions & Contraindications
Warnings & Precautions
Prolonged treatment with full doses of sulfamethoxazole-trimethoprim can lead to macrocytic anaemia, since the combination interferes with the conversion of folic acid to folinic acid. Should this occur, giving folinic acid will reverse it. In diabetic patients on a sulphonylurea drug, Sitrim should be used with caution, as it may potentiate the sulphonylurea's action.
Contraindications
Hypersensitivity to trimethoprim or to sulphonamide medicines rules out this drug, as does a confirmed diagnosis of megaloblastic anaemia caused by folate deficiency. It should also be avoided in patients with marked liver damage, blood disorders, severe kidney impairment, or glucose-6-phosphate dehydrogenase (G6PD) deficiency.
Pregnancy & Breastfeeding
Pregnancy and while breastfeeding: sulphonamides cross the placenta and pass into breast milk, and may cause kernicterus.
⚠️ Talk to your doctor before taking any medicine during pregnancy or while breastfeeding.
Storage
