About Trimethoprim sulfate and Polymyxin B sulfate and its cost
What is this medication? Trimethoprim sulfate and polymyxin B sulfate is a prescription ophthalmic solution used to treat superficial bacterial infections of the eye, such as acute conjunctivitis. By combining two different antibiotics, this medication provides broad-spectrum coverage against several types of bacteria that commonly cause eye irritation, discharge, and redness. It is typically administered as drops directly into the affected eye to target the site of infection and reduce clinical symptoms.
The combination works by inhibiting the growth and reproduction of bacteria. Polymyxin B alters the bacterial cell membrane to increase permeability, while trimethoprim blocks the production of folic acid, which bacteria need to survive and multiply. It is essential to use this medication only for bacterial infections, as it will not work for viral or fungal eye issues. Patients should complete the full duration of the prescription as directed by their healthcare provider to prevent the infection from returning or the bacteria from becoming resistant to the treatment.
Trimethoprim sulfate and Polymyxin B sulfate is made by Allergan. 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 Trimethoprim sulfate and Polymyxin B sulfate?
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 Trimethoprim sulfate and Polymyxin B sulfate?
No — federal law (the Anti-Kickback Statute) prohibits manufacturer copay cards on Medicare, Medicaid, TriCare, and VA prescriptions. But Allergan has a separate Patient Assistance Program for Medicare beneficiaries. Check the options above.
Does my Medicare Part D plan cover Trimethoprim sulfate and Polymyxin B sulfate?
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 Blepharoconjunctivitis?
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.
