Interactions between your drugs

Major

quiNIDine miFEPRIStone

Applies to: Quinidex Extentabs (quinidine) and Mifeprex (mifepristone)

Talk to your doctor before using quiNIDine together with miFEPRIStone. Combining these medications may significantly increase the blood levels of quiNIDine, which may increase the risk and/or severity of side effects. Your doctor may be able to prescribe alternatives that do not interact, or you may need to briefly stop using quiNIDine while you are being treated with miFEPRIStone. In addition, because miFEPRIStone is cleared slowly from the body, the interaction may occur even after you have stopped taking it for a while. 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 increases the blood levels of this medication. If you are only receiving one or two doses, you may take it without regard to meals.

Avoid consuming grapefruit or grapefruit juice during treatment, as it may increase blood levels of the medication to undesirable levels and increase the risk of side effects, including headache, dizziness, fatigue, nausea, vomiting, cramping, diarrhea, hypokalemia (low blood potassium), fluid retention, swelling, and high blood pressure. Talk to your doctor or pharmacist if you have questions on how to take this or other medications you are prescribed.
