How to Take Buspar
The following information reflects FDA-approved prescribing information for Buspar (buspirone). Always follow your prescriber's specific instructions:
- Per FDA-approved prescribing information, typical adult dosing: Most adults start with 7.5 mg twice daily, taken about 10–12 hours apart. Your clinician may adjust slowly, often toward a range of 15–30 mg per day divided into 2 or 3 doses.
- Per FDA-approved prescribing information, take it consistently with or without food: Choose one way and stick to it each day so absorption remains consistent.
- Swallow tablets whole: Take with a small glass of water. Do not crush or chew.
- Per FDA-approved prescribing information, do not use as needed: Buspar is taken on a schedule, not for sudden anxiety. It builds effect gradually over days to weeks.
- Per FDA-approved prescribing information, avoid grapefruit products: They can raise buspirone levels unpredictably.
- Per FDA-approved prescribing information, if you miss a dose: Take it when you remember unless it is close to the next dose. If so, skip the missed dose and return to your regular schedule.
- Take at the same times daily: Morning and evening doses work well for most people and help maintain routine.
If your prescriber gave you a different schedule, follow that plan — Buspar dosing is individualized and often adjusted gradually over time.
