Seroquel’s Approved & Off-Label Uses (Indications)
US FDA Approved Treatment(s)Schizophrenia, bipolar disorder, as an add-on to an antidepressant to treat depression
Popular Off-Label UsesInsomnia, anxiety, Parkinson’s
How Long Until Seroquel Starts Working (Onset of Action)
Unlike other antipsychotics, which can start getting your symptoms under control within 24 hours, Seroquel can take up to a week to work. Unless you’re taking it for sleep. That first 25mg knocks out most people.
Likelihood of Working
Approved uses: Pretty good for schizophrenia, so-so for bipolar mania, fairly good for bipolar depression.
Off-label uses: Excellent for insomnia, good for anxiety. Due to the way Seroquel works and the nature of anxiety spectrum disorders, Seroquel can potentially make your anxiety better or worse at first, then do the exact opposite at a higher dosage. Even if you’re not taking it specifically for anxiety.Learn how Seroquel Compares with Other Drugs
How to Take Seroquel
- For bipolar: PI sheet: start at 100mg a day in two 50mg doses and increase by 100mg to 400mg day by day four. If needed, up it by 200mg a day until reaching 800mg a day by day six.
- We suggest starting with one 25–50mg dose at night if you’re taking another mood stabilizers, or the 100mg a day in two 50mg doses if you aren’t. If you need to increase by 25–50mg a day every 3–4 days and stay at whatever dosage gets your symptoms under control. Unless you’re seriously flipping out, in which case follow the PI sheet’s guidelines until your symptoms are under control or you hit 800mg a day.
- For schizophrenia: PI sheet: start at 50mg a day, divided into two 25mg doses, but they still want to ramp you up to 300–400mg a day by day four.
- We suggest starting with 50mg a day and, as with bipolar disorder, increasing by 25–50mg every 3–4 days until your symptoms are under control. If you’re crazy enough to be getting coded messages in your cereal, especially if you’re NOT eating Alpha-Bits, then get to 300–400mg by day four.

How to Stop Taking Seroquel (Discontinue, Withdrawal)
Your doctor should be recommending that you reduce your dosage by 25–50mg a day every other day if you need to discontinue it. You can stop taking all it immediately if it’s an emergency (e.g. a life-threatening allergic reaction), but I wouldn’t recommend doing that without a doctor’s supervision. The major problem with stopping antipsychotics is a sudden return of your symptoms. Learn More about Taking and Discontinuing Seroquel
Seroquel’s Pros and Cons
- As one of the mildest - and most prescribed - of all antipsychotics it doesn’t really carry the antipsychotic stigma as heavily as the other meds in this class.
- That also means it’s less likely to cause side effects involving prolactin (e.g. leaking nipples and/or man boobs) and movement disorders.
- You’ll sleep until next Tuesday.
- Of course, that could be a good thing, depending on how your life is at this moment.
- Other than the sleep thing, it takes longer than any other atypical antipsychotic to work. * You’ll probably gain weight and you might come down with type 2 diabetes.
Interesting Stuff your Doctor Probably didn’t Tell You about Seroquel
Seroquel is marginally better absorbed with food. So if you feel you need just a little boost in the dosage, try taking it with dinner or a late-night snack. Since Seroquel can make you gain a lot of weight, be careful about that late-night snacking.
Like most drugs older people don’t clear it out of their systems as well, to the point that they may need a lower dosage. That’s not particularly interesting. What is interesting is that Seroquel seems to work better for people under 40 than over 40.
Best Known for
Seroquel is notorious for two things - making you sleep until next Tuesday, and leaving you with one hell of a hangover when you eventually wake up. It’s a lot like trazodone in this regard.

Brain Cooties Aren’t Contagious
Seroquel’s Side Effects (Adverse Reactions)
Typical Side Effects
The usual short-term side effects for second-generation / atypical antipsychotics (SGA/AAP):
Most, if not all of these will go away in a couple of weeks. Except for the excessive sleepiness, which could hang around for as long as you take this med, but is usually not much of a problem once you’re taking more than 100–200mg a day.
However, the excessively sleepiness tends to return if you start taking over 400–600mg a day. That’s also interesting, but many doctors and/or pharmacists will tell you that. The feeling like you were out drinking with the Wolfpack last night goes away after 2 or three days. A week at the most. If it hangs around for longer than that it might eventually go away, and it might not.
And, of course, weight gain. Although the weight gain with Seroquel is not considered to be as bad as that with Zyprexa, for some people it can be as bad, if not worse.
Uncommon Side EffectsDiabetes. Manic reaction. Muscle aches and pains. Getting all sweaty for no good reason. Tremor. Irregular heart beat and prolonged QT interval. While the sexual dysfunctions aren’t as bad as Risperdal (risperidone) or Zyprexa (olanzapine), they can still happen.
Freaky Rare Side EffectsInfanticide - although the lack of Seroquel was the real cause of that tragedy. Priapism (the never-ending hard-on) from an overdose. Kids, don’t try this at home. The PI sheet also lists “bone pain” and “abnormal ejaculation” so I’d be especially careful about taking too much Seroquel as a Cialis substitute in order to stay hard. Unless you’re into that sort of thing.

What You Really Need to be Careful About
quetiapine’s Half-Life & How Long Until It Clears Your System
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 quetiapine’s pharmacokinetics page.
How quetiapine Works
the current best guess at any rateSeroquel is a broad-spectrum atypical/second-generation antipsychotic, and is tied with Zyprexa for third place in how many, and which type, of neurotransmitter receptors it affects. Most of its activity involves reducing the activity 5HT-serotonin and alpha-1a & alpha-2c norepinephrine receptors. Like practically every AP on the planet, Seroquel is a D2 antagonist. Being a potent antagonist at 5-HT2A, 5-HT2C, and 5-HT7, a partial agonist at serotonin 5-HT1A, and a little norepinephrine reuptake inhibition accounts for its antidepressant effect. Because of that last one, and the nature of anxiety spectrum disorders, Seroquel can make you more or less anxious when you start taking it, then do the exact opposite at a higher dosage.

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.

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.

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

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 through our personal experience and the experiences family, friends, what people have reported on various reputable sites all over teh intergoogles, the medications’ product information / summary of product characteristic (PI/SPC) sheets, and from sources that are referenced throughout the site. 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 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 Internet is 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.
