I suppose everyone knows that victrelis and incevek are not new drugs but were used for HIV prior to being used for HCV. With some hiv drugs it says do not ear grapefruit as it will interfere with the drugs efficacy. Although I have not seen this on the list of drug interactions for victrelis or incevek, I was just wondering if anyone knows or has been told by their doctor not to eat them while on treatment. I have had them several times while on treatment, and would like to continue since they are so healthy for you, but I do not want to impede treatment at all. thanks
Research about the interaction of grapefruit juice with drugs suggests that compounds in grapefruit juice, called furanocoumarins (for example, bergamottin), may be responsible for the effects of grapefruit juice. Researchers believe that furanocoumarins block the enzymes in the intestines that normally break down many drugs. One glass of grapefruit juice could elicit the maximum blocking effect, and the effect may persist for longer than 24 hours. Since the effects can last for such a prolonged period of time, grapefruit juice does not have to be taken at the same time as the medication in order for the interaction to occur. Therefore, unlike similar interactions, where the interaction can be avoided by separating the administration of the two interacting agents by a couple of hours, administration of grapefruit juice with susceptible drugs should be separated by 24 or more hours to avoid the interaction. Since this is not practical for individuals who are taking a medication daily, they should not consume grapefruit juice when taking medications that are affected by grapefruit juice.
The grapefruit juice-drug interaction can lead to unpredictable and hazardous levels of certain important drugs.
These are medications with which grapefruit juice should NOT be consumed unless advised by a doctor:
Statins (cholesterol drugs): lovastatin (Mevacor), atorvastatin Lipitor, simvastatin Zocor, simvastatin/ezetimibe (Vytorin)
Antihistamines: fexofenadine (Allegra), (terfenadine (Seldane), taken off the U.S. market
Calcium channel blockers (blood pressure drugs): nimodipine (Nimotop), felodipine (Nitrendipine, Plendil), nisoldipine (Sular), nicardipine (Cardene), verapamil (Verelan)
Psychiatric medications: buspirone (BuSpar), triazolam (Halcion), carbamazepine (Tegretol), diazepam (Valium), midazolam (Versed), sertraline (Zoloft)
Intestinal medications: cisapride (Propulsid) taken off the U.S. market
Immune suppressants: cyclosporine (Neoral), (tacrolimus) Prograf
Pain medications: Methadone
Impotence drug: (erectile dysfunction): sildenafil (Viagra)
HIV medication: saquinavir (Invirase, Fortovase)
