Keytruda, a medication produced by Merck & Co. for the treatment of various forms of cancer, gained approval from the U.S. Food and Drug Administration (FDA) in 2014. Specifically, the FDA approved Keytruda for the treatment of advanced melanoma in September 2014 [1]. Since then, Keytruda has received additional approvals for treating other types of cancer, further expanding its therapeutic applications.

Keytruda, also known as pembrolizumab, is a type of immunotherapy that works by blocking a protein called PD-1, which helps to keep cancer cells hidden from the immune system. By blocking PD-1, Keytruda enables the immune system to recognize and attack cancer cells more effectively [2].

It's important to note that while Keytruda has been a significant development in cancer treatment, it is not without potential side effects. Common side effects include fatigue, cough, nausea, itching, rash, and decreased appetite [3]. Additionally, Keytruda can have serious side effects, such as immune-mediated side effects, which occur when the immune system attacks healthy cells [3].

In summary, Keytruda received FDA approval in 2014 for the treatment of advanced melanoma and has since received additional approvals for other types of cancer. While Keytruda has been a significant development in cancer treatment, it is important to be aware of its potential side effects.
