Patient Education

Co-trimoxazole Injection


Co-trimoxazole injection is used to treat certain infections that are caused by bacteria such as infection of the intestine, lungs (pneumonia), and urinary tract. Co-trimoxazole should not be used in children younger than 2 months of age. Co-trimoxazole injection is in a class of medications called sulfonamides. It works by killing bacteria. Antibiotics such as co-trimoxazole injection will not work for colds, flu, or other viral infections. Taking antibiotics when they are not needed increases your risk of getting an infection later that resists antibiotic treatment.
