Buspirone, or BuSpar, is a prescription drug used to treat anxiety. Buspirone is different from other anti-anxiety drugs because it usually does not cause euphoria, drowsiness or muscle relaxation.
Function
Buspirone reduces anxiety by mimicking some of the chemicals in the brain responsible for feelings of well-being. Most of its activity is on the serotonin receptors.
Time Frame
It takes a week before buspirone begins to reduce the symptoms of anxiety. Buspirone reaches maximum effectiveness after four to six weeks.
Considerations
Buspirone is usually taken twice a day. It is absorbed better if it is taken with food.
Benefits
People are not as likely to abuse buspirone as other anxiety drugs. This makes it a good option for people who have a history of drug abuse or dependence.
Side Effects
The most common side effects of buspirone are nervousness, upset stomach and rapid heart rate. It occasionally causes drowsiness, so people taking buspirone should not drive until they know how the drug affects them.
Warning
Buspirone can increase blood pressure if it is taken with any of the drugs known as monoamine oxidase inhibitors (MAOIs). People with liver or kidney problems and pregnant or breastfeeding women should not take buspirone.
