Common side effects and prevention and treatment methods of Erlotinib/Tarceva

Erlotinib (Erlotinib), as an EGFR-targeting drug, plays an important role in the treatment of non-small cell lung cancer. Although it is less toxic and more convenient to administer than traditional chemotherapy, it still causes some typical side effects. Understanding common side effects and how to prevent and treat them can help patients better adhere to treatment and improve their quality of life.

The most common side effect is skin reaction. Most patients will develop an acne-like rash after taking the medication, often distributed on the face, chest and back. This rash is often a sign that the medicine is working, so there is no need to worry too much. Mild rashes can usually be improved by keeping the skin clean, avoiding strong sun exposure, and using mild skin care products; if the symptoms are obvious, antibiotic ointments or oral medications can be used under the guidance of a doctor to relieve the symptoms.

Digestive system reactions are also common problems. Some patients may experience diarrhea, nausea, loss of appetite, etc. Prevention and treatment methods include dietary adjustments, such as avoiding greasy and irritating foods, increasing the intake of easily digestible foods, and paying attention to hydration to prevent dehydration. If diarrhea is severe, antidiarrheal drugs can be used under the guidance of a doctor.

In addition, some patients may develop mouth ulcers, paronychia, or dry eyes. Most of these symptoms can be relieved through local care, such as using mouthwash to maintain oral hygiene, avoiding wearing tight shoes to reduce paronychia, and using artificial tears under the guidance of a doctor to relieve eye discomfort when necessary.

Less common but noteworthy side effects include liver function abnormalities and interstitial pneumonitis. The former can monitor liver function through regular blood tests. Once abnormalities are found, the doctor will adjust the dose or suspend the medication. Although the latter is rare, if the patient has persistent coughing and shortness of breath, he should seek medical treatment immediately to rule out drug-related lung injury.
