How Long Until BuSpar Starts Working (Onset of Action)
Because of the nonlinear pharmacokinetics, it’s hard to know when you should get an effect from BuSpar, but Bristol-Myers seems to think two to three days should be sufficient. Like most things that work on your serotonin, especially as this is likely to augment an antidepressant, I would make that two to three weeks to decide if BuSpar helping at all.
Likelihood of Working
BuSpar seems to be immensely variable in how it hits people — even studies showing its effectiveness noticed this. Like most meds, it’s all a matter of hitting the right neurotransmitters in the right ways. But since it’s low on the side effects and non-addictive, it’s worth a stop on the med-go-round if you’re experiencing SSRIpoop-out or inadequate relief of anxiety disorders with an SSRI.
The starting dose is usually 5 mg 3 times per day, for a total of 15 per day. With a half life of 3 hours, stepping up every two to three days is not unreasonable biologically — however, it’s insane from a common-sense point of view. Give BuSpar a week between dose step-ups at least, so you can see if it’s doing anything for you at the lower dose. Standard dosages of BuSpar in clinical trials are usually 20 to 30 mg per day; the maximum dosage of BuSpar is 60 mg per day.
How to Stop Taking BuSpar (Discontinue, Withdrawal)
Given a half-live of two to three hours, stepping down by 5 mg at every day is reasonable. Though every other day would be safer. Unless it didn’t do anything at all, including no psychiatric effects, including stuff like making the anxiety or depression worse. In which case go for 10mg a day.
Few drug-drug interactions, weight neutral, and a generally low side effect profile.
A lot of people conclude it doesn’t do shit.
Interesting Stuff your Doctor Probably didn’t Tell You about BuSpar
Per the the PI sheet if you take BuSpar with aspirin you will get a 23% increase in BuSpar’s plasma levels. Now combine that with the increase you get with taking BuSpar on an empty stomach and you get a significant boost. Provided you don’t puke it all up.
BuSpar’s Potential Side Effects (Adverse Reactions)
Typical Side Effects
The usual array of common med symptoms — dizziness, lightheadedness, nausea, headaches. Cold-like symptoms, i.e. less severe flu-like symptoms that every other med on the planet can cause. Nonspecific chest pain.
Uncommon Side Effects
Blood pressure changes. Conjunctivitis. Altered sense of taste. Muscle cramps. Urinary frequency.
Freaky Rare Side Effects
Burning tongue. Photophobia, or turning into Vlad the Impaler. Pelvic inflammatory disease. Yup. BuSpar not only gave someone an STD, they gave them an untreated STD! Alcohol abuse. Honey, I didn’t mean to quit AA! The BuSpar done made me do it!

Half-life is the average time it takes for you to process half of the drug’s active ingredient. If a drug has a half-life of around 24 hours and you take a dose of 100mg, you’ll have roughly the equivalent a 50mg dose after one day, a 25mg dose after two days, and so on. The rule of thumb is: multiply the half-life by five and you get how long it is for the dose you took to be cleared from your bloodstream, so there’s nothing swimming around to attach itself to your brain and start doing stuff1. That’s called “plasma clearance.” Complete clearance is a complex equation based on a lot of factors which may or may not: be published in the PI sheet, include personal data like your weight, or even completely figured out by corporate and independent researchers. It usually winds up being 2–5 days after plasma clearance no matter what2, but can take weeks. Sometimes a drug will clear from your brain and other organs before it clears from your blood. If we’ve found the complete clearance, or how to calculate it if it requires things like your weight and what your piss looks like, you’ll find that on buspirone’s pharmacokinetics page.

As with most of these crazy meds it’s easier to say what BuSpar doesn’t do. BuSpar doesn’t do any of the fun benzodiazepene fuck-you-up-and-get-high effects. BuSpar doesn’t knock you out. BuSpar doesn’t hit GABA.
What BuSpar does do is to keep serotonin within the 5HT1A neurons, thus fooling your brain into thinking it has more serotonin than it actually has. BuSpar also does some noticeable dopamine agonism-antagonism on the dopamine D2receptor. When combined with an SSRI this can help with sexual dysfunction and to prevent SSRI poop-out, per Dr. Stahl in Essential Psychopharmacology.
BuSpar is a quirky med, and there’s currently nothing else approved for use in its class of azapirones. At least in English speaking countries.
While BuSpar’s value for some flavors of anxiety is important, more important is its potential to augment an SSRI that was working great and then quit on you, the bastard.
BuSpar is a maintenance med - i.e. you wait for the calming effects to build up and you keep taking it until you either learn to deal with your problems on your own or you live with the fact you’re going to be taking BuSpar for the foreseeable future. Something I feel should be considered as a maintenance medication long before the benzos, as it doesn’t build up tolerance or addiction, and thus avoids many of the problems with long-term benzodiazepine use, particularly as a prophylactic (preventing anxiety before it starts).

It’s always a good idea to check for drug-drug interactions yourself. Just because most people in the crazy meds business know about really important interactions (e.g. MAOIs and a lot of stuff, warfarin and everything on the planet) doesn’t mean the person who prescribed your meds told you about them, or the pharmacist has all the meds you take at their fingertips like they’re supposed to. Or they have the time to do their jobs properly when not dealing with complete idiots or playing Angry Farmers on the Faecesbooks.

1 Based on Julien's calculations from A Primer of Drug Action, the half-life multiplied by five is the generally accepted estimate of how long it takes a single dose of any given drug to be eliminated from the blood stream/plasma of someone with a normal metabolism. That's also the rough estimate for steady stage if they can't get, or won't provide a number for that.
2 For crazy meds. I have no idea what the average complete clearance is for other types of medications. For all I know there are drugs that utterly vanish from your system in under five passes, and others that won't let go of your squishy bits for years after you stop taking them.
3 Thank you! I'll be here all weak. Be sure to tip your content provider. And don't try the veal, it's cruelicious!

If you have any questions not answered here, please see the Crazymeds BuSpar discussion board. We welcome criticisms of the articles, notifications of bad links, site problems, consumer experiences with medications, etc. I’m not always able to write back. Hence I never answer questions about meds via e-mail that are answered by this or other articles. Especially if they have been repeatedly asked on the forum. That’s why we write these damn things. Questions about which meds are best for your condition should also be asked on the forum; because this is a free site, so the price of admission is making things easier for somebody else searching for the same answer. We don’t deal with children on the forum or in private because after doing this for ten years I don’t have the emotional stamina to deal with kids who have brain cooties.

BuSpar, and all other drug names on this page and used throughout the site, are a trademark of someone else. BuSpar’s PI Sheet will probably have the name of the manufacturer and trademark owner (they’re not always the same company) at or near the very bottom. Or ask Google who the owner is. The way pharmaceutical companies buy each other and swap products like Monopoly™ real estate, the ownership of the trademark may have changed without my noticing. It may of changed hands by the time you finished reading this article.

What happened to us won’t necessarily happen to you. If you still have questions about a medication or condition that were not answered on any of the pages you read, please ask them on Crazy Talk: the Crazymeds Forum.
The information on Crazymeds pertains to and is intended for adults. While some information about children and adolescents is occasionally presented (e.g. US FDA approvals), pediatric-specific data such as dosages, side effects, off-label applications, etc. are rarely included in the articles on drugs or discussed on the forum. If you are looking for information regarding meds for children you’ll have to go somewhere else. Plus we are big pottymouths and talk about S-E-X a lot. Know your sources! Nobody on this site is a doctor, a therapist, or a pharmacist. We don’t portray them either here or on TV. Only doctors can diagnose and treat an illness. While it’s not as bad as it used to be, some doctors still get pissed off by patients who know too much about medications, so tread lightly when and where appropriate. Diagnosing yourself from a website is like defending yourself in court, you suddenly have a fool for a doctor. Don’t be a cyberchondriac, thinking you have every disease you see a website about, or that you’ll get every side effect from every medication1. Self-prescribing is as dangerous as buying meds from fraudulent online pharmacies that promise you medications without prescriptions.
All information on this site has been obtained from the medications’ product information / summary of product characteristic (PI/SPC) sheets and/or medication guides - which is all you get from sites like WebMD, RxList, NAMBLA NAMI, etc., the sources that are referenced throughout the site, our personal experience and the experiences family, friends, and what people have reported on various reputable sites all over teh intergoogles. As such the information presented here is not intended as a substitute for real medical advice from your real doctor, just a compliment to it. You should never, ever, replace what a real doctor tells you with something from a website on the Internet. The farthest you should ever take it is getting a second opinion from another real doctor. Educate yourself - always read the PI/SPC sheet or medication guide/patient information leaflet (PIL) that comes with your medications and never ever throw them away. OK, you can throw away duplicate copies, but keep at least one, as that’s your proof of purchase of having taken a med in case a doctor doubts your medical history. Plus they take up less space than a bottle, although keeping one inside of a pill bottle is even better.

1 While there are plenty of books to help you with hypochondria, for some reason there’s not much in the way of websites. Then again, staying off of the Internetis a large part of curing/managing the disorder.
2 Remember kids, Microsloth operating systems are like TOS Star Trek movies with in that every other one sucks way, way more. With TOS Star Trek movies you don’t want to bother watching the odd-numbered ones. With Microsloth OS you don’t want to buy and install the even-numbered ones. Anyone who remembers ME and Vista knows what I mean.
3 Have I mentioned how open source operating systems for commercial applications is one of the dumbest ideas in the history of dumb ideas?* I don’t even need my big-ass rant any more. Heartbleed has made my case for me. And that’s just the one that got all the media attention. The very nature of an open source operating system makes security as much of an illusion of anonymity. Before you flip out too much: the domain Crazymeds is hosted on uses a version of SSL that is not affected by the Heartbleed bug. That’s one of the many reasons why I pay a lot of money and keep this site on Lunarpages.
* Yes, I know I’m using open source browsers. I also test the site using the now-defunct IE and Safari browsers. Their popularity - and superiority - killed IE and Safari, so that’s why I rely on the open source browsers. It’s like brand vs. generic meds. Sometimes the generic is better than the brand.
