How does this medication work? What will it do for me?
Dacomitinib belongs to the group of cancer-fighting medications known as antineoplastics. Specifically, it belongs to the class of medications called tyrosine kinase inhibitors. It works by recognizing certain types of cancer cells and blocking the action of chemicals that cause them to divide and grow. This may slow down or stop cancers from growing and dividing.
Dacomitinib is used in adults to treat non-small-cell lung cancer that cannot be removed by surgery or has spread to other parts of the body. It is not appropriate for all types of non-small cell lung cancer. It will only interfere with the growth of cancer cells that have a particular mutation (a change) in the "epidermal growth factor receptor". Your doctor should test your cancer for this change in the "EGFR" receptor before starting this medication.

Are there any other precautions or warnings for this medication?
Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Birth control: Use effective birth control while using this medication, as this medication may harm the baby if used during pregnancy. Both men and women should use effective birth control (e.g., condoms, birth control pill) during treatment and for at least 2 months after treatment is finished. If you or your partner become pregnant while taking this medication, contact your doctor immediately.
Diarrhea: Dacomitinib commonly causes diarrhea, which, if it is severe, can lead to dehydration because of fluid loss. While you are taking dacomitinib, make sure you are drinking plenty of fluids. If you experience diarrhea, talk to your doctor. Severe dehydration can cause rapid loss of kidney function and is a medical emergency. If you experience symptoms of dehydration such as decreased tears, sweating, urine production, constipation, headache, or muscle cramps, seek medical attention.
Eye problems: You may experience changes in vision while taking this medication. Tell your doctor if you experience eye pain or redness, or any vision disturbances, such as flashes of light, blurry vision, or double vision.
Liver function: Dacomitinib may reduce liver function and can cause liver problems. Your doctor will monitor your liver function with blood tests while you are taking this medication. If you have liver problems, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
If you experience symptoms of liver problems such as fatigue, feeling unwell, loss of appetite, nausea, yellowing of the skin or whites of the eyes, dark urine, pale stools, abdominal pain or swelling, and itchy skin, contact your doctor immediately.
Lung inflammation: Some people taking this medication have experienced lung inflammation (interstitial lung disease) causing difficulty breathing. This complication can be serious and sometimes fatal. If you experience new or worsening shortness of breath or cough (with or without fever) at any time while you are taking dacomitinib, contact your doctor immediately.
Nail changes: Dacomitinib can cause infection of the skin surrounding the fingernails or toenails. It is important to keep your hands and feet clean and dry, be gentle when trimming your nails and avoid injury to the nails or finger tips. Use gentle soaps and nail products, avoiding harsh soaps and detergents with chemicals. If you experience symptoms of an infection of the nail or nailbed, such as redness, swelling, heat, or pain, contact your doctor as soon as possible.
Skin changes: Dacomitinib can cause changes to the skin, making it dry or red, and can cause acne and peeling. Blisters may form on the palms of the hands and soles of the feet. Applying a good moisturizer to the skin from the time you start taking dacomitinib may help to reduce how severe these effects become. If you experience blistering or peeling skin, report this to your doctor as soon as possible.
