Warnings
WARNINGS The sulfonamides should not be used for the treatment of group A betahemolytic streptococcal infections. In an established infection, they will not eradicate the streptococcus and, therefore, will not prevent sequelae such as rheumatic fever and glomerulonephritis. Deaths associated with the administration of sulfonamides have been reported from hypersensitivity reactions, agranulocytosis, aplastic anemia and other blood dyscrasias. The presence of such clinical signs as sore throat, fever, pallor, purpura or jaundice may be early indications of serious blood disorders. The frequency of renal complications is considerably lower in patients receiving the more soluble sulfonamides. CONTRAINDICATIONS Sulfadiazine is contraindicated in the following circumstances: Hypersensitivity to sulfonamides. In infants less than 2 months of age (except as adjunctive therapy with pyrimethamine in the treatment of congenital toxoplasmosis). In pregnancy at term and during the nursing period, because sulfonamides cross the placenta and are excreted in breast milk and may cause kernicterus.
