Gefitinib is used to treat non-small cell lung cancer that has spread to other parts of the body in people with certain types of tumors. Gefitinib is in a class of medications called kinase inhibitors. It works by blocking the action of a certain naturally occurring substance that may be needed to help cancer cells multiply.
Gefitinib comes as a tablet to take by mouth. It is usually taken with or without food once a day. Take gefitinib at around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take gefitinib exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
If you are unable to swallow the tablets, you may dissolve them in water. Place one tablet in 4 to 8 ounces (120 to 240 mL) of plain, noncarbonated drinking water. Stir with a spoon for about 15 minutes until the tablet is dissolved. Drink the mixture right away. Rinse the glass with another 4 to 8 ounces (120 to 240 mL) of water and drink the rinse water right away to be sure that you swallow all of the medication.
Your doctor may delay or permanently stop your treatment if you experience certain side effects. Be sure to tell your doctor how you are feeling during your treatment with gefitinib.
Before taking gefitinib,
- tell your doctor and pharmacist if you are allergic to gefitinib, any other medications, or any of the ingredients in gefitinib tablets. Ask your pharmacist for a list of the ingredients.
- tell your doctor and pharmacist what prescription and nonprescription medications, vitamins, and nutritional supplements you are taking or plan to take. Be sure to mention any of the following: anticoagulants ('blood thinners') such as warfarin (Coumadin, Jantoven); antifungals such as itraconazole (Onmel, Sporanox) and ketoconazole (Nizoral); metoprolol (Lopressor, Toprol XL, in Dutoprol); phenytoin (Dilantin, Phenytek); and tricyclic antidepressants such as imipramine (Tofranil) and amitriptyline. Many other medications may interact with gefitinib, so be sure to tell your doctor about all the medications you are taking, even those that do not appear on this list. Your doctor may need to change the doses of your medications or monitor you carefully for side effects.
- if you are taking an antacid or an H2 blocker medication for indigestion, heartburn, or ulcers such as cimetidine (Tagamet), famotidine (Pepcid), nizatidine (Axid), or ranitidine (Zantac), take them at least 6 hours before or 6 hours after taking gefitinib.
- if you are taking a proton pump inhibitor medication for indigestion, heartburn, or ulcers such as esomeprazole (Nexium), lansoprazole (Prevacid), omeprazole (Prilosec), pantoprazole (Protonix), or rabeprazole (AcipHex), take it at least 12 hours before or at least 12 hours after taking gefitinib.
- tell your doctor if you have or have ever had pulmonary fibrosis (scarring of the lungs) or other lung or breathing problems, eye or vision problems, or liver disease.
- tell your doctor if you are pregnant or plan to become pregnant. Gefitinib may cause infertility (difficulty becoming pregnant) in females. However, you should use birth control to prevent pregnancy during your treatment with gefitinib and for at least 2 weeks after you stop taking the medication. If you become pregnant while taking gefitinib, call your doctor. Gefitinib may harm the fetus and increase the risk of pregnancy loss.
- tell your doctor if you are breastfeeding. You should not breast-feed while you are taking gefitinib.
Unless your doctor tells you otherwise, continue your normal diet.
Take the missed dose as soon as you remember it. However, if it is less than 12 hours before your next dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).
Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.
It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org
In case of overdose, call the poison control helpline at 1-800-222-1222. Information is also available online at https://www.poisonhelp.org/help. If the victim has collapsed, had a seizure, has trouble breathing, or can't be awakened, immediately call emergency services at 911.
Keep all appointments with your doctor and the laboratory. Your doctor will order certain lab tests to check your body's response to gefitinib.
Do not let anyone else take your medication. Ask your pharmacist any questions you have about refilling your prescription.
It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
