Below are answers to some common questions about cephalexin and cost.

Does the price of cephalexin capsules depend on the strength I use (250 mg, 500 mg, or 750 mg)?

Maybe. Cephalexin is available in different dosing forms and strengths. Your cost may depend on the form and strength of your prescription as well as whether or not you have health insurance.

Cephalexin is available in the following forms and strengths:

  • capsule
    • 250 milligrams (mg)
    • 500 mg
    • 750 mg
  • tablet
    • 250 mg
    • 500 mg
  • suspension
    • 125 mg per 5 milliliters (mL)
    • 250 mg per 5 mL (available in 100-mL and 200-mL bottles)

The cost of different strengths of cephalexin capsules may be the same if you have insurance. This may also apply to the other forms of cephalexin. You can contact your insurance provider to find out more.

If you don’t have insurance, your cost may differ based on the forms and strengths of cephalexin available to you. (For instance, your cost without insurance may be higher for 750-mg capsules than other strengths.)

Your doctor will prescribe the form and strength that is best to treat your type of infection.

Your pharmacist can tell you the exact cost of your cephalexin prescription.

How much does cephalexin cost without insurance?

How much your cephalexin prescription costs depends on several factors. These include:

  • the form of the drug (suspension, capsule, or tablet)
  • how often you take cephalexin
  • the number of days of your treatment

If you need help paying for your cephalexin prescription, talk with your pharmacist or doctor. Also, see “Can I get help paying for cephalexin?” below for more information.

Can my cost for cephalexin be different from one pharmacy to another without insurance?

Yes. If you don’t have insurance, your cost for cephalexin may differ depending on the pharmacy you use. It’s a good idea to contact a few pharmacies to check the cost of cephalexin in your area.

Remember, all generic versions of cephalexin prescriptions are equally effective. So, if you don’t have insurance, you can use whichever pharmacy will charge you the least for this drug.

The generic drug cephalexin comes as a brand-name version called Keflex. A generic drug is an exact copy of the active drug in a brand-name medication. The generic is considered to be just as safe and effective as the original drug. And generics tend to cost less than brand-name drugs.

To find out how the costs of Keflex and cephalexin compare, talk with your doctor, pharmacist, or insurance provider.

If you’ve been prescribed cephalexin and you’re interested in using Keflex instead, talk with your doctor. They may prefer one version over another. You’ll also need to check with your insurance provider since it may only cover one drug or the other.
