About Sulfameth/Trimeth-DS and its cost
What is this medication? Sulfamethoxazole/trimethoprim DS is a combination antibiotic medication often sold under brand names such as Bactrim DS or Septra DS. It contains two active ingredients that work synergistically to block the production of folic acid in bacteria, which effectively stops them from multiplying. This medication is classified as a sulfonamide antibiotic and is designed to eliminate various types of bacterial infections throughout the body.
Healthcare providers typically prescribe this drug to treat conditions such as urinary tract infections, middle ear infections, and respiratory issues like bronchitis. It is also effective against certain intestinal infections and can be used to prevent or treat specific types of pneumonia in patients with weakened immune systems. Because it is an antibiotic, it will not be effective against viral infections like the common cold or influenza.
Sulfameth/Trimeth-DS 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 Sulfameth/Trimeth-DS?
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 Sulfameth/Trimeth-DS?
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 Sulfameth/Trimeth-DS?
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.
