BuSpar (Buspirone) Side Effects, Important Information, Before Taking & More

Buspirone is an anxiolytic drug commonly sold under the name Buspar. It is designed to counter anxiety and provide short-term relief from the symptoms experienced by people suffering from General Anxiety Disorder (GAD). It functions by affecting the chemicals in your brain that could potentially create imbalances leading to anxiety development. Researchers are not completely sure of how exactly it goes about to reduce anxiety. They are of the belief that it counters some of the resultant effects of dopamine and serotonin, two neurotransmitters that upon secretion generate symptoms of anxiety. Unlike other medicines in the anxiolytic category, Buspirone does not sedate the user. Some symptoms of anxiety disorders include:

  • Dizziness
  • Irritability
  • Upset stomach
  • Tension
  • Worry
  • Insomnia
  • Fear
  • Pounding heartbeat

How to use:

Follow the directions present on the instruction label. Do not use the medicine without a prescription by the doctor. The medication is typically instructed to be taken 2 to 3 times daily with or without food. It is important though to stick to one of the two, with or without a meal, so the medicine can be absorbed the same way.

The medicine typically comes in tablet form and can be split if the dosage prescribed is less than what a single tablet contains. The tablet comes in a dose of 5, 10, 15 and 30 mg.

The dosage is determined by age, medical history, and response to the drug. Furthermore, limit the intake of grapefruit while on this medication as it can increase the level of buspirone in the patient’s bloodstream that could potentially cause an overdose or increase its symptoms.

Usually, doctors prescribe a dose of 7.5 g every 12 hours. Some eventually increase the dose by 5 mg or so after a few days to provide greater relief to some patients. BuSpar is a relatively slow-acting drug and may take a few weeks before showing the desired results.

If you are switching from the long-term use of another anxiety controlling drug to BuSpar, it is advised to decrease the dose of the other drug rather than ceasing its use immediately to avoid withdrawal symptoms.

Use this drug regularly for optimal results.



Before using Buspirone, tell your doctor in detail about your allergies. The medicine is not to be used if you suffer from problems related to liver or kidney, bipolar disorder, and Parkinson’s disease.

This drug may cause dizziness and drowsiness, and therefore, one should avoid operating heavy machinery and driving. Use of marijuana and alcohol should also be limited as they could interact with the drug and produce unwanted side effects or amplify them.

It is unknown if the use of this medicine in pregnant women has any adverse effects, but it is recommended only to use this drug during pregnancy when absolutely unavoidable. Furthermore, it is not known if the drug can be transferred to the baby via breast milk. However, similar drugs pass through breast milk and have negative effects on the baby so, it is advised not to breastfeed while using BuSpar.
