Keytruda is a medication used for the treatment of various types of cancer, including melanoma, lung cancer, and head and neck cancer. The cost of Keytruda can vary depending on factors such as the dosage and duration of treatment, as well as the patient's insurance coverage.

According to the Drug Patent Watch [1], Keytruda's patent is set to expire in 2028. This means that currently, Keytruda is only available as a brand-name medication, which tends to be more expensive than generic drugs.

However, there are financial support programs available for patients who need help paying for Keytruda. The official Keytruda website [2] offers information on financial assistance programs for eligible patients. These programs include co-pay assistance, patient assistance, and free drug programs.

In terms of insurance coverage, Medicare does cover Keytruda for certain types of cancer [3]. However, coverage may vary depending on the patient's specific plan and other factors. Patients should consult with their insurance provider to determine their coverage and out-of-pocket costs for Keytruda.

In conclusion, the cost of Keytruda can vary depending on a variety of factors, including dosage, duration of treatment, and insurance coverage. Patients who need financial assistance can explore the various programs available through the official Keytruda website. Medicare does cover Keytruda for certain types of cancer, but coverage may vary depending on the patient's specific plan. Patients should consult with their insurance provider to determine their coverage and out-of-pocket costs for Keytruda.
