How Long Until Wellbutrin Starts Working (Onset of Action)
Usually two-three weeks. Like all antidepressants, especially reuptake inhibitors, you should give it up to a month, maybe six weeks, before giving up, barring any really nasty side effects or you can tell nothing positive is happening at all. Meds that work on dopamine tend to act quickly, so it could start having positive results in a few days.
Likelihood of Working
Pretty freaking good. The side effects or something else may make it suck too much to keep taking it, or there’s too much potential for trouble in the first place, but Wellbutrin is one of those meds that usually work. Sometimes a little too well.
Glaxo-Smith Kline (GSK) says this for the Sustained Release (SR) form:
Initial Treatment:The usual adult target dose is 300 mg/day, given as 150 mg twice daily. Dosing should begin at 150 mg /day given as a single daily dose in the morning . If the 150-mg initial dose is adequately tolerated, an increase to the 300-mg/day target dose, given as 150 mg twice daily , may be made as early as day 4 of dosing.
Increasing the Dosage Above 300 mg/day:As with other antidepressants, the full antidepressant effect may not be evident until 4 weeks of treatment or longer. An increase in dosage to the maximum of 400 mg/day, given as 200 mg twice daily, may be considered for patients in whom no clinical improvement is noted after several weeks of treatment at 300 mg/day.--the Wellbutrin SR PI sheet
The XL form has the same dosages, but with just one dose a day.
The only thing I don’t like is raising the dosage after three days. I really think you should wait at least five, preferably seven-eight days (see steady state below) before going up to the next higher dosage. Assuming you have the luxury of not feeling like killing yourself every hellish hour you’re awake.
How to Stop Taking Wellbutrin (Discontinue, Withdrawal)
Based on its complex pharmacokinetics, your doctor should be recommending that you reduce your dosage by 100–150mg a day (for the more popular SR and XL forms, 75mg for the immediate release form), every 5–7 days (a week is just easiest way to keep track of things) if you need to stop taking it. There have been reports of more than the usual problems that come from stopping any crazy med abruptly, or just too quickly. These include mania (not uncommon when you stop taking antidepressants cold turkey), dystonia (painful muscle contractions & spasms).
Low chance of sexual side effects, unless you consider making you hornier with or without premature/spontaneous orgasms sexual side effects. None of the weight gain associated with SSRIs & SNRIs. Often a very effective and relatively fast-acting antidepressant, as dopamine and norepinephrine reuptake inhibition are frequently part of, if not the answer for a lot of people.
Anything used recreationally, so it can be abused and has to be avoided by anyone with an eating disorder or other addictive behaviors. The abuse potential is a serious problem, as Wellbutrin is one of the few modern antidepressants that can kill you if you take too much.
Interesting Stuff your Doctor Probably didn’t Tell You about Wellbutrin
Bupropion is also the active ingredient in Zyban, a drug used to quit smoking. Depending on your HMO schedule or your health insurance, you may want to get a prescription for Zyban. Why? Sometimes it’s cheaper. While mental health coverage is now supposed to be treated like everything else by health insurance providers, the pervasive anti-crazy bigotry guarantees that won’t be the case. While smokers are treated like second-class citizens, non-crazy smokers are still considered human and don’t get anywhere near as much shit as we do for taking drugs to quit smoking. And some insurance companies have a points system like car insurance. If you get too crazy, your rates go way up, but if you do something positive like try to quit smoking, your rates go down. So check with the person who works in your doctor’s office about the rates and the system, and see if you need to game the system with a prescription for the same drug with a different name and lower maximum dosage.

Wellbutrin’s Potential Side Effects (Adverse Reactions)
Typical Side Effects
Agitation, anxiety, insomnia, weight loss (it’s undergone trials both as, and part of, a weight loss medication), headache, dry mouth, nausea, constipation, dizziness. Most of these are transitory, but the weight loss, agitation and insomnia tend to stick around.
Uncommon Side Effects
Strange body odor, sweating, nervousness and tremor. Basically it could make you look like the guilty party, so you better have a damn good alibi at all times in case some big, unsolved crime goes down. Also: seizures.
Freaky Rare Side Effects
Change in hair color. They swore Lady Clairol wasn’t involved! There was also new hair, possibly in unusual places. Painful erections, unusual ejaculations, ballism, and outright impotence. You know you’re the butt of one of God’s little jokes if you become impotent or get one or more of the dick-pain side effects and hornier.
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 bupropion’s pharmacokinetics page.
While Wellbutrin has the potential make you happy, horny, skinny, and quit smoking, it is only consistent at making you not depressed - which probably counts as happy so long as you don’t end up all irritable, anxious, and pissed off3 - and helping you to stop smoking, while being unlikely to make you gain weight or affect your libido. Weight loss and treating sexual dysfunction are off-label uses of Wellbutrin and, like most off-label uses, you only want to try it if the regular treatments don’t work, because the odds aren’t as good or the side effects are worse. Or both.
Really, Dr. Drew… oh, wait, Dr. Drew just took GSK’s money and told everyone the facts as they were known - like it is less likely to cause weight gain or sexual side effects than SSRIs - except for that part about taking a shitload of money from GSK. It was another doctor, who wasn’t as famous, who was repeating what the pharm reps were telling him about the happy, horny, skinny pill. Maybe. If you don’t need it to keep from falling to the floor in a fetal position and sobbing for hours if the newspaper reprinted yesterday’s sudoku. They should have known better than that.

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 Along with other symptoms of a dysphoric mania. Not all manias are happy-happy joy-joy, kids.
4 Technically the FDA asked Teva & Impax to voluntarily remove Budeprion XL from the market, much like the way the IRS assists us in voluntary compliance with tax code. Go ahead, search irs.gov for the phrase "promote voluntary compliance", with or without quotes. I feel so much better about myself knowing I've been volunteering for my country.

If you have any questions not answered here, please see the Crazymeds Wellbutrin 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.

Wellbutrin, and all other drug names on this page and used throughout the site, are a trademark of someone else. Wellbutrin’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.

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.
