Drug Interaction Report

Using verteporfin together with imatinib may cause an increase in photosensitivity reactions, which could cause your skin to burn when exposed to light. Check with your doctor to see if you should temporarily withhold any of your medications before and after treatment with verteporfin. You should avoid exposure of skin or eyes to sunlight or bright indoor lights (examination lamps, operating room lamps, tanning beds, lights at close proximity) for 5 days after treatment with verteporfin. If you must go outdoors in the daylight during this 5-day time frame it is important to protect your skin and eyes by wearing protective clothing and dark sunglasses, even if you cannot see the sun (e.G., cloudy day). Exposing your skin to normal indoor lighting is helpful as it will help your body get rid of verteporfin more quickly, so you do not need to stay inside in the dark. Talk to your doctor if you have any questions or concerns. 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.

Grapefruit juice may increase the blood levels of certain medications such as imatinib. You should avoid consumption of grapefruit and grapefruit juice during treatment with imatinib. However, if you have been regularly consuming grapefruit or grapefruit juice with the medication, then it is advisable for you to talk with your doctor before changing the amounts of these products in your diet, as this may alter the effects of your medication. Contact your doctor if your condition changes or you experience increased side effects. Orange juice is not expected to interact.
