The price you pay for tamsulosin can vary. It may depend on your treatment plan, your insurance coverage (if you have insurance), and the pharmacy you use. To find out how much you’ll pay for tamsulosin, talk with your doctor, pharmacist, or insurance provider.

Note: If you have insurance, you may need to get prior authorization before your insurance provider will cover tamsulosin. This means your insurer and your doctor will discuss the drug in regard to your treatment. Then the insurance company will determine whether it’s covered. If tamsulosin requires prior authorization and you don’t receive it before you start treatment, you could pay the full cost of the drug.

Be sure to ask your insurance company whether tamsulosin requires prior authorization.

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

Tamsulosin comes as the brand-name drug Flomax. To find out how costs of Flomax and tamsulosin compare, talk with your doctor, pharmacist, or insurance provider.

If you’ve been prescribed tamsulosin and you’re interested in taking Flomax 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 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 tamsulosin 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 tamsulosin if approved by your insurance company. This could reduce your number of trips to the pharmacy and help lower the cost of the drug. If you’re interested in a 90-day supply of tamsulosin, talk with your doctor, pharmacist, or insurance provider.

Use a mail-order pharmacy to get your medication. Using a mail-order pharmacy might help lower your cost for tamsulosin. 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. If you don’t have health insurance, talk with your doctor or pharmacist. They may be able to suggest online pharmacy options that could work for you.
