What is Buspirone?

Buspirone is an anti-anxiety drug that affects chemicals in the brain that may be unbalanced in people with anxiety.

Buspirone is not an anti-psychotic medication and should not be used in place of medication prescribed by your doctor for mental illness.

Buspirone is used to treat symptoms of anxiety, such as fear, tension, irritability, dizziness, pounding heartbeat, and other physical problems.

This medication 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 to use Buspirone

Take buspirone exactly as it was prescribed for you by your doctor. Follow all directions on your prescription label. Your doctor may occasionally change your dose to make sure you get the best results from your treatment. Do not take this medicine in larger or smaller amounts or for longer than suggested.

Some buspirone tablets are scored so you can break the tablet into 2 or 3 pieces in order to take a smaller amount of the medicine at each dose. Do not use a tablet if it has not been broken correctly and the piece is too big or too small.

If you have switched to buspirone from another anxiety drug, you may need to slowly decrease your dose of the other medication rather than stopping suddenly

This medication can cause false positive results with certain medical tests. You may need to stop using the medicine for at least 48 hours before your test. Tell any doctor who cures you that you are using 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.
