Drug Interaction Report

You may experience reduced absorption of halofantrine in the presence of food. Halofantrine should be taken on an empty stomach at least 1 hour before or 2 hours after food. This will make it easier for your body to absorb the medication. Also, while taking halofantrine, you should avoid grapefruits and grapefruit juice. Grapefruit can raise the levels of halofantrine in your body and lead to increased adverse effects. Do not increase or decrease the amount of grapefruit products in your diet without first talking to your doctor.

Alcohol can increase the nervous system side effects of dantrolene such as dizziness, drowsiness, and difficulty concentrating. Some people may also experience impairment in thinking and judgment. You should avoid or limit the use of alcohol while being treated with dantrolene. Do not use more than the recommended dose of dantrolene, and avoid activities requiring mental alertness such as driving or operating hazardous machinery until you know how the medication affects you. Talk to your doctor or pharmacist if you have any questions or concerns.
