Buspar (buspirone) is an antianxiety agent prescribed for the treatment of anxiety. Buspar is available as a generic drug. Common side effects of Buspar include:
- feeling tired,
- blurred vision,
- dry mouth,
- upset stomach,
- stuffy nose,
- sore throat,
- ringing in the ears,
- excitement, and
- sleep problems (insomnia or strange dreams).
Buspar usual adult starting dose is 10-30mg daily in 2-3 divided doses up to a maximum of 60mg a day. Common drug interactions of Buspar include monoamine oxidase (MAO) inhibitors (for example, isocarboxazid ), trazodone (Desyrel), warfarin (Coumadin), erythromycin, itraconazole (Sporanox), nefazodone (Serzone) and rifampin. There are no adequate studies of Buspar in pregnant women and it is not known if Buspar is secreted in human breast milk. Use during pregnancy is not recommended unless the potential benefit outweighs the potential unknown risk to the fetus. It is unknown if Buspar passes into breast milk or if it could harm a nursing baby. Consult your doctor before breastfeeding.
Our Buspar Side Effects Drug Center provides a comprehensive view of available drug information on the potential side effects when taking this medication.
This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.
Are you currently using buspirone HCL?
Take this medication by mouth, usually 2 or 3 times a day or as directed by your doctor. You may take this medication with or without food, but it is important to choose one way and always take it the same way so that the amount of drug absorbed will always be the same.
Buspirone may come in a tablet that can be split to get the correct dose for you. Follow the manufacturer’s Patient Instruction Sheet or ask your pharmacist how to split the tablet to get your dose.
Avoid eating grapefruit or drinking grapefruit juice while taking this medication unless your doctor or pharmacist says you may do so safely. Grapefruit can increase the chance of side effects with this medicine. Ask your doctor or pharmacist for more details.
Dosage is based on your medical condition and response to therapy. Use this medication regularly in order to get the most benefit from it. To help you remember, use it at the same times each day. When this medication is started, symptoms of anxiety (e.g., restlessness) may sometimes get worse before they improve. It may take up to a month or more to get the full effect of this medication.
Inform your doctor if your symptoms persist or worsen.
Buspirone is a prescription medication used to treat anxiety.
It belongs to a group of anti-anxiety drugs called anxiolytics, but it seems to work somewhat differently than other drugs in the class.
Though researchers don’t know exactly how buspirone reduces anxiety, they believe it competes with serotonin and dopamine, which are neurotransmitters (chemical brain messengers) involved with causing anxiety symptoms.
Buspirone isn’t for treating occasional stress associated with everyday life. Rather, doctors prescribe buspirone for anxiety disorder and short-term relief of anxiety symptoms.
You may be diagnosed with anxiety disorder if you have at least one full month of anxiety symptoms such as shakiness, tension, irritability, dizziness, worry, fear, upset stomach, and trouble sleeping.
The Food and Drug Administration (FDA) approved buspirone in 1986 for the drug manufacturer Bristol-Myers Squibb, under the brand name BuSpar.
In 2001, the FDA approved a generic version of buspirone for several drug manufacturers, and Bristol-Myers Squibb discontinued the brand name BuSpar.
Recently, researchers began studying other possible uses for buspirone.
A 2013 study published in the journal International Review of Neurobiology found that buspirone may be an effective treatment for Tourette syndrome, a brain disorder that causes people to make uncontrolled and repetitive movements and sounds (tics).
An earlier study, published in 2011 in the journal Therapeutic Advances in Neurological Disorders, also found that buspirone may reduce the frequency and severity of Tourette syndrome tics.
You should not take buspirone if you are taking a monoamine oxidase inhibitor (MAOI), a type of drug used for treating depression.
Examples of MAOIs include phenelzine (Nardil) and tranylcypromine (Parnate).
Taking buspirone with MAOIs can cause a dangerous increase in blood pressure.
Research has shown that the safety of buspirone does not vary by age. For short-term use (no more than six weeks), it’s as safe in people 65 and older as in other adults and in children six to 17.
However, long-term safety of buspirone in children is unknown.
Let your doctor know if you’re taking other medications for anxiety.
Many anxiety medications can be dangerous if you stop taking them suddenly. They can cause a dangerous withdrawal reaction that could include anxiety, insomnia, abdominal pain, and seizure.
Switching from one of these drugs to buspirone will not prevent a withdrawal reaction because buspirone does not act like these other medications. Instead, you have to taper down the dose of the drugs gradually.
Your doctor should know if you have certain conditions so he or she can decide if buspirone is the right drug for you. They include:
- Kidney disease
- Liver disease
- Drug or alcohol abuse
- Pheochromocytoma (a rare tumor that causes high blood pressure)
Buspirone ‘High’ and Addiction
Numerous online and anecdotal reports have suggested that some people abuse buspirone for a narcotic-like “high.”
Buspirone abuse can result in:
- Nausea or vomiting
- Memory loss
- Lack of coordination
Take buspirone only as directed by your doctor, and keep this and all other drugs away from children, teenagers, and anyone for whom the drug has not been prescribed.
Buspirone and Pregnancy
Buspirone has not been tested enough to know whether it’s safe to take during pregnancy.
Women should let their doctor know if they are or may become pregnant before taking buspirone.
Also, the drug may pass through breast milk, but it’s not known whether it’s safe to take buspirone while breastfeeding.

Taking Buspar (Buspirone) With Tylenol Sinus
There are no known interactions between buspirone and the active ingredients that are found in Tylenol Sinus Severe Daytime. It would be considered safe to treat the congestion symptoms that you are having with the Tylenol product.
Tylenol Sinus Severe Daytime contains:
- Acetaminophen (analgesic)
- Phenylephrine (decongestant)
Buspirone (Buspar) an anti-anxiety medication that should not be taken with MAO inhibitors, including linezolis, methylene blue injection, selegiline, rasagiline, and phenelzine
Caution should be used when taking this drugs with other CNS active medications. Avoid taking this medication with grapefruit juice as this could affect the concentration of buspirone that is in the body. This medication commonly causes sedation and dizziness.

BusPar (Buspirone)… anyone try this?
I posted this on another thread, here’s a copy:
Since you are taking Buspar, I would suggest taking your dose at night with the melatonin. Optimal ratio is 15mg-20mg buspar with 3mg melatonin time release. More effects are felt if you take a morning dose of buspar as well, around 15-20mg. Effects from this combo are felt within one to three days (yes, that’s days.) It is a powerful neurogenesis stimulating combination and helps with everything you just mentioned, depression, anxiety, and cognitive processes (thought processes, clear thinking) It has a slight serotonergic and dopaminergic quality to it so you will feel an uplifted mood that comes and goes throughout the day. Caffeine seems to spark this effect as well as some supplements like 5HTP. The most interesting thing about this is that you can take the combination for two-three months or more and then stop, and the effects will still be felt, almost like your brain has made permanent changes in neuron connections to unlearn negative thinking and stay away from depression. It does this by provoking neurogenesis in the regions of the brain that are responsible for mood, memory, thinking, imagination, and learning. This effect may be subdued however, if you drink alcohol on a daily basis and/or take recreational drugs. These substances reduce neurogenesis and cancel out the effect of the combination. Anything else that reduces neurogenesis will reduce the effect as well, like many prescription drugs such as Benzodizepines, Gabapentin, ADHD medicines, and so on. So, if you are careful with what you take, you have a good chance of success with feeling better and having feelings of happiness, long term. Anti-depressants are surprisingly okay to take with this combination as most of them (SSRI) do increase neurogenesis on their own (nowhere near the amount that this combination does.) I’ve been taking this combination for 4+ years, and have noticed increases in mental processes and positive effects in mood and thinking that get stronger to this day. It doesn’t hurt to just try it out, as buspar is really hit or miss with a lot of people. For me, it has been a life-changing medicine. You may or may not feel these effects, but it’s worth it to try for a couple weeks.
