At Merck, we believe that no one should go without the medicines or vaccines they need.

That is why the company provides certain medicines and adult vaccines for free to people who do not have prescription drug or health insurance coverage and who, without our assistance, cannot afford their Merck medicine and vaccines. This is consistent with Merck's long-held values and traditions of putting patients first.

If you or someone you know needs help paying for medicines or adult vaccines, the Merck Patient Assistance Program, Inc., may be able to help.

Merck is a proud participant in the Medicine Assistance Tool.

Medicines or adult vaccines distributed through the Merck Patient Assistance Programs are free of charge to all eligible patients.

Merck is not associated with any individuals or organizations that may charge patients a fee to assist them in completing enrollment forms for our programs. These individuals or organizations are acting independently of Merck, and do not have Merck's consent.

These programs are not insurance.
