The price you pay for allopurinol can vary. Your cost may depend on your treatment plan, your insurance coverage, and the pharmacy you use.

To find out how much you’ll pay for allopurinol, 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 allopurinol. This means your insurer and your doctor will discuss allopurinol in regard to your treatment. Then the insurance company will determine whether the drug is covered.

If allopurinol requires prior authorization and you don’t receive it before you start treatment, you could pay the full cost of the drug. So be sure to ask your insurance company whether allopurinol requires prior authorization.

Below are answers to some frequently asked questions about allopurinol and cost.

Is the price of allopurinol 100-mg tablets less expensive than the 300-mg tablets?

If you have insurance that covers prescription drugs, ask your insurance provider for information about the cost of allopurinol. If you don’t have insurance, your doctor or pharmacist can let you know how much you’ll pay for this drug.

Where can I buy allopurinol for the lowest price?

If you’re looking for the lowest price for allopurinol and you have insurance, you might want to contact your insurance provider. Some insurance providers have preferred pharmacies, and your medication may cost less at these pharmacies.

If you don’t have insurance coverage for prescriptions, ask your pharmacist what the cash price is for allopurinol. That’s the amount you’ll pay without any discounts.

Allopurinol is a generic drug. This means it’s an exact copy of the active drug in a brand-name medication. A generic is considered to be just as safe and effective as the original drug. And generics generally cost less than brand-name drugs.

Allopurinol comes in brand-name versions called Aloprim and Zyloprim. To find out how the costs of these drugs and allopurinol compare, talk with your doctor, pharmacist, or insurance provider.

If you’ve been prescribed allopurinol and you’re interested in using Aloprim or Zyloprim 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. This is because 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 allopurinol tablets 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 allopurinol if approved by your insurance company. This could reduce your number of trips to the pharmacy and help lower the cost of allopurinol. If you’re interested in getting a 90-day supply of this drug, 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 allopurinol. 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.
