Can Keytruda Cause Long-Term Side Effects?

Understanding Keytruda and Its Mechanism of Action

Keytruda, also known as pembrolizumab, is a medication used to treat various types of cancer, including melanoma, lung cancer, and breast cancer. It is a type of immunotherapy that works by blocking the action of a protein called PD-1, which helps cancer cells evade the immune system. By blocking PD-1, Keytruda allows the immune system to recognize and attack cancer cells more effectively.

Common Short-Term Side Effects of Keytruda

Like all medications, Keytruda can cause side effects. The most common short-term side effects of Keytruda include:

* Fatigue
* Muscle or joint pain
* Nausea and vomiting
* Diarrhea
* Rash
* Itching
* Hives

These side effects are usually mild to moderate and temporary, and they often resolve on their own once treatment is completed.

Long-Term Side Effects of Keytruda: What We Know So Far

While Keytruda has been shown to be effective in treating various types of cancer, there is growing concern about the potential long-term side effects of the medication. According to a study published in the Journal of Clinical Oncology, up to 30% of patients treated with Keytruda may experience long-term side effects, including:

* Endocrinopathies: Keytruda has been linked to the development of endocrinopathies, such as hypothyroidism, hyperthyroidism, and adrenal insufficiency.
* Neurological toxicities: Some patients may experience neurological toxicities, such as seizures, encephalitis, and peripheral neuropathy.
* Gastrointestinal toxicities: Long-term use of Keytruda has been linked to gastrointestinal toxicities, including colitis, diarrhea, and abdominal pain.
* Cardiovascular toxicities: There is a risk of cardiovascular toxicities, including hypertension, cardiac arrhythmias, and cardiac failure.

What Do the Experts Say?

According to Dr. Jedd Wolchok, a medical oncologist at Memorial Sloan Kettering Cancer Center, "While Keytruda has been shown to be effective in treating various types of cancer, we need to be aware of the potential long-term side effects of the medication. As we continue to use Keytruda in clinical practice, we need to monitor patients closely for signs of long-term toxicity."

What Can Patients Do to Minimize the Risk of Long-Term Side Effects?

Patients taking Keytruda can take several steps to minimize the risk of long-term side effects:

* Monitor your health closely: Patients should monitor their health closely and report any side effects to their healthcare provider.
* Follow treatment guidelines: Patients should follow treatment guidelines carefully and attend regular follow-up appointments with their healthcare provider.
* Stay hydrated: Patients should stay hydrated by drinking plenty of water and other fluids.
* Avoid strenuous activities: Patients should avoid strenuous activities and get plenty of rest.
