Montelukast is a generic drug. This means it contains an exact copy of the active drug in its brand-name version. A generic is considered just as safe and effective as the original drug, but usually costs less.

Montelukast comes as the brand-name drug Singulair. To find out how the costs of Singulair and the various forms of montelukast compare, talk with your doctor, pharmacist, or insurance provider.

If you’ve been prescribed montelukast and you’re interested in taking Singulair instead, talk with your doctor. They may prefer that you take one version instead of the other. In addition, you’ll need to check with your insurance provider, as it may only cover one version of the drug or the other.

Why is there such a cost difference between brand-name drugs and generics?

Years of research and testing are needed to ensure that brand-name drugs are safe and effective. This testing can make the drugs expensive. The drugmaker of a brand-name drug can sell the drug for up to 20 years. After that, other drugmakers can create generic versions. This competition in the market can lead to lower costs for generics. And because generics have the same active ingredients as brand-name drugs, they don’t need to be studied again. This can also lead to lower generic costs.

If you take montelukast long term, you may be able to lower your costs in the following ways:

Look into getting a 90-day supply of your medication. You may be able to get a 90-day supply of montelukast if approved by your insurance company.

Use a mail-order pharmacy to get your medication. Using a mail-order pharmacy might help lower your cost for montelukast. Plus, you could get your medication without leaving home. Some Medicare plans may help cover the cost of mail-order drugs. You may also be able to get a 90-day supply of the drug through mail order.
