Interactions between your drugs
fenfluramine lumefantrine
Applies to: fenfluramine and artemether / lumefantrine
Consumer information for this interaction is not currently available.
MONITOR: Coadministration with lumefantrine may increase the plasma concentrations of drugs that are substrates of the CYP450 2D6 isoenzyme. In vitro, lumefantrine significantly inhibits the activity of CYP450 2D6 at therapeutic plasma concentrations. Adverse effects of drugs that are primarily metabolized by CYP450 2D6 may be increased; however, clinical data have not been reported.
MANAGEMENT: Caution is advised if lumefantrine is used concurrently with medications that undergo metabolism by CYP450 2D6, particularly those with a narrow therapeutic range. Dosage adjustments as well as clinical and laboratory monitoring may be appropriate for some drugs whenever lumefantrine is added to or withdrawn from therapy.

Drug and food interactions
fenfluramine food
Applies to: fenfluramine
Using fenfluramine with alcohol can increase the risk of cardiovascular side effects such as increased heart rate, chest pain, or blood pressure changes. In addition, you may also be more likely to experience nervous system side effects such as dizziness, drowsiness, depression, and difficulty concentrating. You should avoid or limit the use of alcohol while being treated with fenfluramine. Do not use more than the recommended dose of fenfluramine, and avoid activities requiring mental alertness such as driving or operating hazardous machinery until you know how the medication affects you. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medication without first talking to your doctor.
lumefantrine food
Applies to: artemether / lumefantrine
Each dose of lumefantrine should be taken with food such as milk, infant formula, pudding, porridge, or broth. Food helps the medication get absorbed into the bloodstream, so the medication may not work as well when taken on an empty stomach. If unable to be swallowed whole, lumefantrine tablets may be crushed and mixed with one to two teaspoons of water in a clean container and consumed immediately after mixing. The container should then be rinsed with more water and the contents consumed. This should be followed by eating as soon as possible. Avoid drinking grapefruit juice during treatment with lumefantrine. Grapefruit juice can cause too much of the medication to be in the blood. 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.
