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

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

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

Do not use buspirone if you have taken an MAO inhibitor in the past 14 days. A dangerous drug interaction could occur. MAO inhibitors include isocarboxazid, linezolid, methylene blue injection, phenelzine, rasagiline, selegiline, and tranylcypromine.

Buspirone is not FDA-approved for use by anyone younger than 18 years old, but this medicine has been used in children and adolescents under close medical supervision and at the appropriate dosage.

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

You may take buspirone with or without food but take it the same way each time.

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. Follow your doctor's instructions about how much of the tablet to take.

If you have switched to buspirone from another anxiety medication, you may need to slowly decrease your dose of the other medication rather than stopping suddenly. Some anxiety medications can cause withdrawal symptoms when you stop taking them suddenly after long-term use.

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 treats you that you are using buspirone.

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature, away from light, excess heat, and moisture (not in the bathroom).

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org

Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.
