Does dacomitinib/dacomitinib affect the heart?

Dacomitinib/Dacomitinib (Dacomitinib) is a targeted therapy drug mainly used to treat malignant tumors such as non-small cell lung cancer. However, like many other drugs, dacomitinib can have a range of effects on the patient's body, including on the heart.

Dacomitinib does have the potential to cause certain effects on the heart. Some studies indicate that this drug may increase the risk of irregular heartbeats and heart failure. Arrhythmia refers to an abnormal rhythm of the heartbeat, which may cause patients to feel palpitation, chest tightness and other discomforts; while heart failure is a condition in which the heart cannot effectively pump blood to meet the needs of the body, which may lead to symptoms such as fatigue and difficulty breathing.

For patients being treated with dacomitinib, if they experience chest pain, palpitations, shortness of breath and other heart-related discomfort symptoms, they should seek medical treatment immediately and inform the doctor of the drugs they are using. Depending on the patient's specific situation, the doctor may need to conduct heart-related tests such as electrocardiogram to evaluate heart function and adjust the treatment plan as needed.

In addition to heart problems, dacomitinib may cause other adverse effects. For example, diarrhea, rash, paronychia (infection of the nail bed), stomatitis (inflammation of the mouth), dry skin, decreased appetite, and nausea are all common side effects associated with dacomitinib treatment. Although these side effects may cause some discomfort to the patient, they can usually be controlled with supportive care, such as the use of skin moisturizers, antidiarrheal medications, and oral rinses.

While using dacomitinib, patients should pay close attention to their physical condition, especially heart-related symptoms. At the same time, communicate with the doctor regularly and provide timely feedback on any discomfort so that the doctor can promptly adjust the treatment plan to ensure the safety and effectiveness of the treatment.
