Drug and food interactions

Moderate

busPIRone food

Applies to: buspirone

You should avoid the use of alcohol while being treated with busPIRone. Alcohol can increase the nervous system side effects of busPIRone such as dizziness, drowsiness, and difficulty concentrating. Some people may also experience impairment in thinking and judgment. Patients receiving busPIRone should preferably avoid the consumption of large amounts of grapefruits and grapefruit juice. If this is not possible, the busPIRone dose should be taken at least 2 hours before or 8 hours after grapefruit or grapefruit juice. Large amounts of grapefruit and grapefruit juice may cause increased levels of busPIRone in your body. This can lead to increased adverse effects such as drowsiness.
