How should I take Tykerb?
Take Tykerb exactly as prescribed by your doctor. Do not take in larger or smaller amounts or for longer than recommended. Follow the directions on your prescription label. Tykerb comes with patient instructions for safe and effective use. Follow these directions carefully. Ask your doctor or pharmacist if you have any questions. Be sure to also read the medication guide or patient instructions for capecitabine (Xeloda) or letrozole (Femara). Take Tykerb on an empty stomach, at least 1 hour before or 1 hour after a meal. The usual dose of Tykerb is equal to 5 or 6 tablets given at one time. The number of tablets you take will depend on your condition and whether you are also taking capecitabine (Xeloda) or letrozole (Femara).
Do not crush a Tykerb tablet. Swallow the pill whole. The medicine from a crushed or broken pill can be dangerous if it gets on your skin. If this occurs, wash your skin with soap and water and rinse thoroughly. You may swallow each Tykerb tablet one at a time, but take the entire dose (all 5 or 6 tablets) at the same time each day. Tykerb is usually taken together with capecitabine (Xeloda) in a 21-day cycle. Tykerb is given once daily for all 21 days in a row, and capecitabine is given twice daily for only the first 14 days of the cycle. This 21-day cycle is then repeated until your doctor decides that Tykerb is no longer an appropriate treatment for your condition. Follow your doctor's instructions. Capecitabine (Xeloda) must be taken with food or within 30 minutes of eating. Tykerb is usually taken together with letrozole (Femara) daily for as long as you continue to take letrozole. Take Tykerb for the full prescribed length of time. This medication is usually continued unless your condition gets worse or you have serious side effects.
Your heart function will need to be checked before you start treatment with Tykerb. To be sure this medication is not causing harmful effects, your liver function will need to be checked every 4 to 6 weeks. Visit your doctor regularly.
