What is erlotinib?

Erlotinib is used to treat non-small cell lung cancer or pancreatic cancer that has spread to other parts of the body (metastatic).

Erlotinib is usually given after other treatments have failed.

Erlotinib may also be used for purposes not listed in this medication guide.

How should I take erlotinib?

Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose. Use the medicine exactly as directed.

Take erlotinib on an empty stomach, at least 1 hour before or 2 hours after eating.

If you have diarrhea while taking erlotinib: start taking anti-diarrhea medicine such as loperamide (Imodium) to quickly treat diarrhea. Drink extra fluids and call your doctor if you have severe diarrhea.

You may need frequent medical tests to be sure this medicine is not causing harmful effects. Your cancer treatments may be delayed based on the results.

Store at room temperature away from moisture and heat.

What happens if I miss a dose?

Take the medicine (on an empty stomach) as soon as you can, but skip the missed dose if it is almost time for your next dose. Do not take two doses at one time.

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.

Overdose symptoms may include severe diarrhea or severe skin rash.

What should I avoid while using erlotinib?

Avoid smoking. It can make erlotinib less effective.

Grapefruit may interact with erlotinib and lead to unwanted side effects. Avoid the use of grapefruit products.

Avoid taking an antacid within several hours before or after you take erlotinib. Ask a doctor or pharmacist before taking any medicine to reduce stomach acid, such as cimetidine (Tagamet).

Avoid taking an herbal supplement containing St. John's wort.

Avoid exposure to sunlight or tanning beds. Erlotinib can cause skin rash, dryness, or other irritation. Wear protective clothing and use sunscreen (SPF 30 or higher) when you are outdoors.

Avoid using skin products that can cause dryness or irritation, such as acne medications, harsh soaps or skin cleansers, or skin products that contain alcohol.
