Interactions between your drugs
rilpivirine encorafenib
Applies to: dolutegravir / rilpivirine and encorafenib
Consumer information for this interaction is not currently available.
CONTRAINDICATED: Coadministration with potent inducers of CYP450 3A4 may significantly decrease the plasma concentrations of rilpivirine, which is primarily metabolized by the isoenzyme. In 16 study subjects given rilpivirine (150 mg once daily) with the potent CYP450 3A4 inducer rifampin (600 mg once daily), mean rilpivirine peak plasma concentration (Cmax), systemic exposure (AUC) and trough plasma concentration (Cmin) were reduced by 69%, 80% and 89%, respectively. The pharmacokinetics of rifampin and its metabolite, 25-desacetylrifampin, were not significantly altered.
MANAGEMENT: Given the risk of reduced viral susceptibility and resistance development associated with subtherapeutic antiretroviral drug levels, concomitant use of rilpivirine with potent CYP450 3A4 inducers is considered contraindicated.
Drug and food interactions
encorafenib food
Applies to: encorafenib
You should preferably avoid consumption of grapefruit and grapefruit juice while taking encorafenib. Grapefruit and grapefruit juice can significantly increase the blood levels of encorafenib. This may increase the risk of serious side effects such as bleeding complications, eye and vision problems, liver problems, irregular heart rhythm, and development of new skin cancers. 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.
rilpivirine food
Applies to: dolutegravir / rilpivirine
Food significantly increases the absorption of rilpivirine. You should take each dose of rilpivirine with a meal. Taking it on an empty stomach may lead to inadequate blood levels and reduced effectiveness of the medication. Grapefruit juice can also increase the absorption of rilpivirine and should preferably be avoided.
