We have several programs that offer information about product access, co-pay assistance, and medicines or vaccines free of charge for eligible patients in the United States.

Merck Access Program

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


Merck provides coupons to help eligible privately insured patients with a prescription afford the out-of-pocket costs of certain Merck products. Eligibility restrictions and terms and conditions apply.

Patient Assistance Programs

The Merck Patient Assistance Program* provides certain medicines and adult vaccines free of charge to eligible individuals who, without assistance, could not afford the prescribed Merck products they need.
