bus-pi-rone

What does it do?

Buspirone is used to treat and prevent anxiety. It is also sometimes used for other conditions.

Before you start

  • Tell your doctor if you have liver or kidney problems, Parkinson’s disease or if you have ever had a seizure.
  • Tell your doctor if you are pregnant, planning to become pregnant, or breastfeeding.

How should you take it?

Take buspirone regularly as directed with a glass of water. You can take buspirone with or without food, but take it the same way each time.

What if you forget a dose?

Take the missed dose as soon as you remember. If it is close to the time for your next dose, skip the missed dose and carry on as normal. Do not take two doses at the same time.

Can you take other medicines?

Some medicines available without a prescription may react with buspirone including:

  • some antihistamines (may be in anti-allergy, anti-nausea and cough/cold medicines)
  • prochlorperazine
  • fluconazole (e.g. Diflucan®) or miconazole (e.g. Daktarin Oral Gel®)

Tell your pharmacist or doctor about all medicines or treatments that you may be taking, including vitamins, herbal products (e.g. St John's wort, valerian) or recreational drugs.
