Trimethoprim-sulfamethoxazole (TMP-SMX, generic for Bactrim, and also abbreviated SMZ-TMP) is an antibiotic. It can be used to treat urinary tract infections and skin infections, and can be used to treat infections caused by MRSA (Methicillin-resistant S. aureus) bacteria.
TMP-SMX is known to cause birth defects and should not be used by pregnant women. TMP-SMX may cause your skin to be more sensitive to sunlight. Avoid the sun while taking this medication.
Avoid if allergic to sulfa drugs. TMP-SMX can cause rare but fatal reactions including life-threatening types of rash (Stevens-Johnson syndrome, toxic epidermal necrolysis), liver failure (fulminant hepatic necrosis), and life-threatening low blood counts (aplastic anemia and thrombocytopenia). TMP-SMX can cause severe diarrhea (including C. difficile diarrhea). Stop taking TMP-SMX at the first sign of any rash.

Only your Duration Health provider can decide, based on your medical history and other factors, whether it is medically appropriate for you to receive prescriptions. We do not sell prefabricated bags of pharmaceuticals. Each Duration Health Med Kit that contains prescription medications is custom assembled, tailored to each individual patient's needs.
Duration Health is not a pharmacy, is not a nonprescription retailer, and does not sell medications directly. To be able to deliver a customized kit of medications, Duration Health has partnered with a third-party mail order pharmacy. You may request that any prescriptions be sent to an alternate pharmacy. Duration Health charges an administrative convenience fee for its services, but Duration Health does not sell prescription or over-the-counter ("OTC") drugs, mark-up the cost of prescription or OTC drugs, or retain any portion of the fees our affiliated pharmacy charges to you. Nor does Duration Health provide medical advice about or prescribe OTC medications. In states where Duration Health’s physician consultation services are not offered, Duration Health only offers OTC products and does not provide clients with access to obtain a physician consultation. Clients are free to purchase OTC medications of their choice as an OTC-only kit.
