Precautions
Do not this medication if you are allergic to buspirone, or if you have used an MAO inhibitor such as isocarboxazid (Marplan), phenelzine (Nardil), rasagiline (Azilect), selegiline (Eldepryl, Emsam), or tranylcypromine (Parnate) within the past 14 days. Serious, life-threatening side effects can occur if you take buspirone before the MAO inhibitor has cleared from your body.
Before taking buspirone, tell your doctor if you are allergic to any drugs, or if you have:
- kidney disease; or
- liver disease.
If you have any of these conditions, you may not be able to use buspirone, or you may need a dosage adjustment or special tests during treatment.
FDA pregnancy category B. This medication is not expected to be harmful to an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant during treatment.
It is not known whether buspirone passes into breast milk or if it could harm a nursing baby. Do not use this medication without telling your doctor if you are breast-feeding a baby.
Do not give this medication to a child younger than 18 years old.
Buspirone can cause side effects that may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be awake and alert.
Avoid drinking alcohol. It may increase some of the side effects caused by buspirone.
Cold or allergy medicine, narcotic pain medicine, sleeping pills, muscle relaxers, and medicine for seizures, or depression can add to sleepiness caused by buspirone. Tell your doctor if you regularly use any of these other medicines.
Grapefruit and grapefruit juice may interact with buspirone and lead to potentially dangerous effects. Discuss the use of grapefruit products with your doctor. Do not increase or decrease the amount of grapefruit products in your diet without first talking to your doctor.
