What is the most important information I should know about sulfamethoxazole and trimethoprim?
You should not use this medication if you are allergic to sulfamethoxazole or trimethoprim, if you are pregnant or breast-feeding, or if you have anemia (lack of red blood cells) caused by folic acid deficiency.
Before using this medication, tell your doctor if you have kidney or liver disease, a folic acid deficiency, asthma or severe allergies, a thyroid disorder, HIV or AIDS, porphyria, G6PD deficiency, or if you are malnourished.
Take this medicine for the full prescribed length of time. Your symptoms may improve before the infection is completely cleared. Skipping doses may also increase your risk of further infection that is resistant to antibiotics. Sulfamethoxazole and trimethoprim will not treat a viral infection such as the common cold or flu.
Antibiotic medicines can cause diarrhea, which may be a sign of a new infection. If you have diarrhea that is watery or has blood in it, call your doctor. Do not use any medicine to stop the diarrhea unless your doctor has told you to.
Avoid exposure to sunlight or tanning beds. This medication can make you sunburn more easily. Wear protective clothing and use sunscreen (SPF 30 or higher) when you are outdoors.
