It should be noted, however, that there are little clinical data on the use of sulfamethoxazole and trimethoprim injection in serious systemic infections due to Haemophilus influenzae and Streptococcus pneumoniae.
Pneumocystis Carinii Pneumonia Sulfamethoxazole and trimethoprim injection is indicated in the treatment of Pneumocystis carinii pneumonia in children and adults.
Cough, shortness of breath, and pulmonary infiltrates are hypersensitivity reactions of the respiratory tract that have been reported in association with sulfonamide treatment.
The sulfonamides should not be used for the treatment of group A beta-hemolytic streptococcal infections.
Sulfamethoxazole and trimethoprim are also contraindicated in pregnant patients and nursing mothers, because sulfonamides pass the placenta and are excreted in the milk and may cause kernicterus.
Sulfamethoxazole and trimethoprim are contraindicated in infants less than 2 months of age.

PLEASE READ THE DISCLAIMER CAREFULLY BEFORE ACCESSING OR USING THIS SITE. The stability of the various dilutions listed above must be based on the actual amount of drug added to the various solutions above.FATALITIES ASSOCIATED WITH THE ADMINISTRATION OF SULFONAMIDES, ALTHOUGH RARE, HAVE OCCURRED DUE TO SEVERE REACTIONS, INCLUDING STEVENS-JOHNSON SYNDROME, TOXIC EPIDERMAL NECROLYSIS, FULMINANT HEPATIC NECROSIS, AGRANULOCYTOSIS, APLASTIC ANEMIA, AND OTHER BLOOD DYSCRASIAS.SULFONAMIDES, INCLUDING SULFONAMIDE-CONTAINING PRODUCTS SUCH AS SMX AND TMP INJECTION, SHOULD BE DISCONTINUED AT THE FIRST APPEARANCE SKIN RASH OR ANY SIGN OF ADVERSE REACTION.The presence of 10 mg percent sulfamethoxazole in plasma decreases the protein binding of trimethoprim by an insignificant degree; trimethoprim does not influence the protein binding of sulfamethoxazole.Excretion of sulfamethoxazole and trimethoprim is primarily by the kidneys through both glomerular filtration and tubular secretion.PCP: 15-20mg/kg/day (based on TMP component) divided q6h.
