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.
