Interactions between your drugs

Moderate

quiNIDine pemigatinib

Applies to: Quinaglute Dura-Tabs (quinidine) and pemigatinib

Consumer information for this interaction is not currently available.

ADJUST DOSING INTERVAL: Coadministration with pemigatinib may increase the systemic exposure of orally administered drugs that are substrates of the P-glycoprotein (P-gp) efflux transporter. The pharmacologic effect and toxicity of the substrate may be increased. Pemigatinib has been shown in in vitro studies to be a P-gp inhibitor in vitro. However, no pharmacokinetic data are available from drug interaction studies.

MANAGEMENT: Caution is recommended with the concomitant use of pemigatinib with medications that are substrates of P-gp, particularly those with a narrow therapeutic range. The manufacturer advises that if concomitant use is required, pemigatinib should be administered either 6 hours before or after the P-gp substrate.

Drug and food interactions

Major

pemigatinib food

Applies to: pemigatinib

Pemigatinib may be taken with or without food. Do not consume grapefruit, grapefruit juice, or any supplements that contain grapefruit extract during treatment with pemigatinib unless directed otherwise by your doctor. Grapefruit juice can increase the blood levels of pemigatinib. This may increase the frequency and severity of serious side effects such as elevated phosphate levels in the blood (which can eventually lead to low blood calcium levels; calcium deposits in the skin, muscles, and other tissues; anemia; muscle cramps; seizures; and irregular heart rhythm), eye and vision problems, joint pain, mouth sores and inflammation, hair loss, diarrhea, nausea, vomiting, and constipation. 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.

Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
