About Isosorbide Mononitrate and its cost
What is this medication? Isosorbide mononitrate is a prescription medication belonging to a class of drugs called nitrates. It works by relaxing and widening the blood vessels, which allows blood to flow more easily to the heart muscle. By improving blood flow and reducing the amount of work the heart must do, this medication is primarily used to prevent chest pain, also known as angina, in patients with coronary artery disease.
This medication is intended for long-term, daily use to manage chronic heart conditions rather than for immediate relief of sudden symptoms. It is important to understand that isosorbide mononitrate will not stop an angina attack once it has already begun. Patients are typically advised to follow a specific dosing schedule to ensure the medication remains effective over time and to help prevent the body from building up a tolerance to its effects.
Isosorbide Mononitrate is made by Lannett. 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 Isosorbide Mononitrate?
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 Isosorbide Mononitrate?
No — federal law (the Anti-Kickback Statute) prohibits manufacturer copay cards on Medicare, Medicaid, TriCare, and VA prescriptions. But Lannett has a separate Patient Assistance Program for Medicare beneficiaries. Check the options above.
Does my Medicare Part D plan cover Isosorbide Mononitrate?
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 Angina pectoris?
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.
