Drug interactions

Moderate drug interactions

Moderate:

lapatinib lonapegsomatropin

Applies to: Tykerb (lapatinib) and lonapegsomatropin

Talk to your healthcare provider before using lonapegsomatropin together with lapatinib as lonapegsomatropin may alter the blood levels and effects of lapatinib. The importance of this interaction may be higher in certain patients, depending on what lapatinib is being used to treat. You may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications. Contact your healthcare provider if your symptoms worsen or your condition changes during treatment with these medications. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Food/lifestyle interactions

Moderate food/lifestyle interactions

Moderate:

lapatinib Food/Lifestyle

Applies to: Tykerb (lapatinib)

Take lapatinib on an empty stomach 1 hour before or 1 hour after a meal unless otherwise directed by your doctor. This will make it easier for your body to absorb the medication. The lapatinib dose is administered once daily and should not be divided. The usual dose of lapatinib is equal to 5 tablets. You may swallow each tablet one at a time, but take the entire lapatinib dose at the same time each day. If you are receiving therapy with lapatinib you should be advised to avoid grapefruits and grapefruit juice. Grapefruit can raise the levels of lapatinib in your body and lead to dangerous side effects.
