Before using this medication, tell your doctor or pharmacist your medical history, especially of: kidney problems, liver problems, stomach/intestinal problems (such as ulcers, diverticular disease), eye disease (such as severe dry eyes, keratitis), use of contact lenses.

This drug may cause blurred vision. Do not drive, use machinery, or do anything that needs clear vision until you are sure you can perform such activities safely. Limit alcoholic beverages.

This medication may make you more sensitive to the sun. Limit your time in the sun. Avoid tanning booths and sunlamps. Use sunscreen and wear protective clothing when outdoors. Tell your doctor right away if you get sunburned or have skin blisters/redness.

Before having surgery, tell your doctor or dentist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).

Tell your doctor if you are pregnant or plan to become pregnant. You should not become pregnant while using afatinib. Afatinib may harm an unborn baby. Ask about reliable forms of birth control while using this medication and for at least 2 weeks after the last dose. If you become pregnant, talk to your doctor right away about the risks and benefits of this medication.

Since this drug can be absorbed through the skin and lungs and may harm an unborn baby, women who are pregnant or who may become pregnant should not handle this medication or breathe the dust from the tablets.

It is unknown if this drug passes into breast milk. Because of the possible risk to the infant, breastfeeding is not recommended while using this drug and for 2 weeks after the last dose. Consult your doctor before breastfeeding.

Side Effects

Mouth sores, pain/redness/swelling of lips, dry/itchy skin, acne, nose bleed, runny nose, nausea/vomiting, or loss of appetite may occur. If any of these effects last or get worse, tell your doctor or pharmacist promptly.

Remember that this medication has been prescribed because your doctor has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

Diarrhea is a common side effect. Drink plenty of fluids as directed by your doctor to reduce your risk of dehydration. Your doctor may prescribe anti-diarrhea medication (such as loperamide) to control your symptoms. Tell your doctor right away if you develop: diarrhea that is severe or doesn't stop, symptoms of dehydration (such as unusual decreased urination, unusual dry mouth/thirst, fast heartbeat, or dizziness/lightheadedness).

Tell your doctor right away if you have any serious side effects, including: signs of eye disease (such as vision changes, eye redness/pain, light sensitivity, eye discharge), signs of low level of potassium in the blood (such as muscle cramps, weakness, irregular heartbeat), signs of bladder infection (such as burning/pain when you urinate, urgent or frequent urination, fever), signs of skin infection around nails/toenails (such as skin irritation/redness around the nail, change in nail color).

Get medical help right away if you have any very serious side effects, including: symptoms of lung problems (such as trouble breathing, chest pain), symptoms of heart failure (such as shortness of breath, swelling ankles/feet, unusual tiredness, unusual/sudden weight gain).

Afatinib may rarely cause serious (possibly fatal) liver disease or tear in the stomach or intestinal wall (perforation). Get medical help right away if you have symptoms such as: nausea/vomiting that doesn't stop, loss of appetite, dark urine, stomach/abdominal pain, yellowing eyes/skin.

Afatinib can commonly cause a rash that is usually not serious. However, you may not be able to tell it apart from a rare rash that could be a sign of a severe reaction. Get medical help right away if you develop any rash.

A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.
