Edit list (add/remove drugs)

Interactions between your drugs

Major

simeprevir fedratinib

Applies to: Olysio (simeprevir) and fedratinib

Using simeprevir together with fedratinib is not recommended. Combining these medications may significantly increase the blood levels of simeprevir. This may increase the risk of serious side effects such as skin rash and skin reactions to sunlight (photosensitivity), which may be severe enough to require hospitalization. Your doctor may be able to prescribe alternatives that do not interact. 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.

Drug and food interactions

Moderate

simeprevir food

Applies to: Olysio (simeprevir)

Food significantly increases the absorption of simeprevir. You should take each dose of simeprevir with food. Taking it on an empty stomach may lead to inadequate blood levels and reduced effectiveness of the medication.

Moderate

fedratinib food

Applies to: fedratinib

Grapefruit juice can increase the blood levels of fedratinib. This may increase the risk of serious side effects such as Wernicke's encephalopathy, a potentially fatal condition of the brain associated with thiamine (vitamin B1) deficiency; low blood cell counts, which can lead to anemia, bleeding, and infections; severe diarrhea, nausea, and vomiting; problems in the liver or pancreas; and development of other cancers. You should avoid the consumption of grapefruit and grapefruit juice during treatment with fedratinib. You may take the medication with or without food, but taking it with a high-fat meal may help reduce nausea and vomiting. Talk to your doctor or pharmacist if you have questions on how to take this or other medications you are prescribed. 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.
