Buspirone, sold under the brand name Buspar among others, is a medication primarily used to treat anxiety disorders, particularly generalized anxiety disorder.[5][6] Benefits support its short term use.[7] It has not been found to be effective in treating psychosis.[5] It is taken by mouth, and it may take up to four weeks for an effect.[5][6]
Common side effects include nausea, headaches, dizziness, and trouble concentrating.[5][7] Serious side effects may include hallucinations, serotonin syndrome, and seizures.[7] Use in pregnancy appears to be safe but has not been well studied, while use during breastfeeding is not recommended.[7][8] How it works is not clear but it is unrelated to benzodiazepines.[5]
Buspirone was first made in 1968 and approved for medical use in the United States in 1986.[5][6] It is available as a generic medication.[7] A month supply in the United Kingdom costs the NHS about £10 as of 2019.[7] In the United States the wholesale cost of this amount is about US$3.[9] In 2017, it was the 80th most commonly prescribed medication in the United States, with more than ten million prescriptions.[10][11]
