What are the side effects of Tepotinib Hydrochloride Hydrate?

Tepotinib Hydrochloride Hydrate is a medication used to treat non-small cell lung cancer (NSCLC) that carries specific genetic mutations, particularly involving MET exon 14 skipping alterations. While its targeted approach offers hope to many patients, it is essential to be aware of the potential side effects associated with its use. Understanding these side effects can help patients and healthcare providers manage and mitigate the risks effectively.

One of the most commonly reported side effects of Tepotinib is peripheral edema, which is swelling usually in the lower limbs. This condition occurs due to the accumulation of fluid in the tissues and can cause discomfort and mobility issues. In some cases, the edema can become severe and may require medical intervention to manage.

Another frequent side effect is nausea. Patients might feel queasy or have an unsettled stomach, which can sometimes lead to vomiting. Managing diet and using prescribed anti-nausea medications can help alleviate this symptom. Alongside nausea, diarrhea is also a commonly reported issue. This can lead to dehydration and electrolyte imbalances if not appropriately managed.

Fatigue is another significant side effect that patients may experience. This is not just ordinary tiredness but a persistent feeling of exhaustion that can interfere with daily activities and overall quality of life. Ensuring adequate rest and engaging in light physical activity as tolerated can help manage this symptom.

Liver function abnormalities are also a concern with Tepotinib. Elevated liver enzymes detected through blood tests can indicate liver inflammation or damage. Regular monitoring of liver function tests is crucial to detect any issues early and to take appropriate actions, such as dosage adjustments or, in severe cases, discontinuing the medication.

Interstitial lung disease (ILD) is a less common but serious side effect. This condition involves inflammation and scarring of the lung tissue, which can lead to breathing difficulties. Symptoms such as a persistent cough, chest pain, or shortness of breath should be reported to a healthcare provider immediately for further evaluation and treatment.

Additionally, Tepotinib can cause low levels of albumin in the blood, a condition known as hypoalbuminemia. Albumin is a protein that helps maintain fluid balance in the body, and low levels can lead to complications like edema and increased risk of infection.

Other side effects include decreased appetite, rash, and musculoskeletal pain. While these are generally less severe, they can still affect a patient's comfort and quality of life. Consulting with healthcare providers for symptom management strategies can be beneficial.

In summary, while Tepotinib Hydrochloride Hydrate offers a promising treatment option for patients with specific genetic forms of NSCLC, it is accompanied by a range of potential side effects. Awareness and proactive management of these side effects are essential to optimize treatment outcomes and maintain the patient's quality of life. Regular monitoring and open communication with healthcare providers can help navigate these challenges effectively.
