In patients receiving sulfamethoxazole, adequate fluid intake is necessary to reduce the risk of crystalluria; the daily urine output should be 1200 to 1500 mL or more.

Treatment with sulfonamides should be discontinued immediately a rash appears because of the danger of severe allergic reactions such as the Stevens-Johnson syndrome.
Sulfamethoxazole should be given with care to patients with renal or hepatic impairment and is contra-indicated in patients with severe renal or hepatic failure or with blood disorders. Dosage reduction may be necessary in renal impairment. Complete blood counts and urinalyses with microscopic examination should be carried out particularly during prolonged therapy. Sulfamethoxazole should not be given to patients with a history of hypersensitivity to sulfonamides as cross-sensitivity may occur between drugs of this group.
