We’re here to help you get the information you need to guide you on your health journey.

Everything that motivates us starts with you.

We work hard to bring you the medications and vaccines that help fight some of the most serious health concerns facing all of us.

And we know it’s sometimes hard to know where to look for help.

Do you need help paying for your medications?

We understand that many things can add to the stress of medical treatment. If you are unable to afford your prescribed medications, we may be able to help you. See what programs are available to eligible patients in the U.S.

Looking for coupons on Merck products?

Select Merck brands offer coupon programs to eligible, privately-insured patients to save on their out-of-pocket costs. To see if a coupon is available, please go to the product brand website. Coupons are not available for patients who are uninsured or patients with Medicare or other Government Program insurance. Other eligibility restrictions and Terms and Conditions apply.

Have a question about your insurance coverage or financial assistance options?

The Merck Access Program may be able to help patients and health care providers answer questions related to insurance coverage and financial assistance options for certain Merck products.

Unable to afford your prescription?

Merck Patient Assistance Program provides certain medicines and adult vaccines for free to people who qualify.

What is a clinical trial?

A clinical trial is a research study in human volunteers that helps determine whether investigational vaccines, medicines, or new uses for existing vaccines and medicines are safe and work well.

Medical advances can only happen through the efforts of many people, especially the patients who volunteer for clinical trials. They are our partners in research.
