Keytruda, a medication produced by Merck & Co. for the treatment of various forms of cancer, can be quite expensive. However, there are assistance programs available to help offset the cost of this drug.

Merck's patient assistance program, known as Merck Helps, offers eligible patients Keytruda at no cost. This program is designed for patients who do not have prescription drug coverage and meet certain income requirements. More information about Merck Helps can be found on Merck's official website [1].

Another resource for patients seeking assistance with Keytruda costs is the Partnership for Prescription Assistance (PPA). The PPA is a comprehensive database of patient assistance programs, including those for Keytruda. Patients can search for programs based on their medication and personal situation [2].

Additionally, DrugPatentWatch.com provides information on drug patents and their expiration dates. Keytruda's patent is set to expire in 2028 [3]. This information is important for patients as the expiration of patents often leads to the availability of generic versions of the drug, which can be less expensive.

In summary, patients seeking assistance with Keytruda costs can utilize Merck Helps, the Partnership for Prescription Assistance, and keep track of Keytruda's patent expiration date through DrugPatentWatch.com.
