How should I take BuSpar?

Take BuSpar 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 BuSpar with or without food but take it the same way each time.

Some BuSpar 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 BuSpar 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.

Buspirone 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 BuSpar.

Store at room temperature away from moisture, heat, and light.
