What is buspirone used for?
Buspirone is commonly used to treat anxiety. It may help you think more clearly, relax, worry less, and take part in everyday life. It may also help you to feel less jittery and irritable, and may control symptoms such as trouble sleeping, sweating, and pounding heartbeat.
Buspirone is a medication for anxiety (anxiolytic) that works by affecting certain natural substances in the brain (neurotransmitters).
How should I take buspirone?
Take this medication by mouth, usually 2 or 3 times a day or as directed by your doctor. You may take this medication with or without food, but it is important to choose one way and always take it the same way so that the amount of drug absorbed will always be the same.
Buspirone may come in a tablet that can be split to get the correct dose for you.
Limit the amount of grapefruit you may eat or drink (less than one quart a day) while being treated with this medication unless your doctor directs you otherwise. Grapefruit may increase the amount of buspirone in your bloodstream. Consult your pharmacist or doctor for more information.
Dosage is based on your medical condition and response to therapy. Use this medication regularly in order to get the most benefit from it. To help you remember, use it at the same times each day. When this medication is started, symptoms of anxiety (e.g., restlessness) may sometimes get worse before they improve. It may take up to a month or more to get the full effect of this medication.
