About Sulfamethoxazole and Trimethoprim and its cost
What is this medication?
Sulfamethoxazole and trimethoprim is a combination antibiotic used to treat a wide variety of bacterial infections. This medication consists of two different drugs that work together to block the production of folic acid in bacteria, which eventually stops their growth and reproduction. Because it targets bacteria, this treatment is effective for conditions such as middle ear infections, urinary tract infections, and respiratory issues like bronchitis. It is important to remember that this drug only treats bacterial infections and will not work for viral illnesses like the common cold or the flu.
Sulfamethoxazole and Trimethoprim is made by Sun. Like most brand-name drugs, it's priced at a high list price — but patients rarely pay that list price. The options above are the real paths most people use to get it affordably.
Common questions
What's the cheapest way to afford Sulfamethoxazole and Trimethoprim?
It depends on your insurance. On Medicare, apply for the manufacturer's Patient Assistance Program (PAP) — it gives the drug free if you meet income requirements. With private insurance, the manufacturer copay card usually drops your copay to $0-$25. Uninsured patients should compare the PAP with Cost Plus Drugs cash price.
Can I use a copay card with Medicare for Sulfamethoxazole and Trimethoprim?
No — federal law (the Anti-Kickback Statute) prohibits manufacturer copay cards on Medicare, Medicaid, TriCare, and VA prescriptions. But Sun has a separate Patient Assistance Program for Medicare beneficiaries. Check the options above.
Does my Medicare Part D plan cover Sulfamethoxazole and Trimethoprim?
Part D coverage varies by plan. We query the CMS Prescription Drug Plan file to show you what percentage of plans cover it and at what tier. For your exact copay, pick "Medicare" above and check your plan's Summary of Benefits, or log in to Medicare.gov.
How long does a Patient Assistance Program take?
Most PAPs take 2-6 weeks from application to first fill. Ask the manufacturer about a "bridge supply" — many will ship 30 days free while your application is being reviewed so you don't go without the drug.
What if I have a high-deductible plan?
For generics, Cost Plus Drugs cash price is often cheaper than your deductible-phase copay. For brand names, the manufacturer copay card almost always wins. A GoodRx coupon can be a last resort for uncovered drugs, but it doesn't count toward your deductible.
Are there charity grants for Chronic Bronchitis?
Charities like HealthWell Foundation, PAN Foundation, Good Days, and the National Organization for Rare Disorders provide copay help for specific conditions. Funds often run out mid-year — apply early. We list the specific grants for your condition in the options above.
