Schizophrenia, bipolar disorder (one of the first and predating lithium), intractable hiccoughs, severe nausea & vomiting (cancer chemotherapy severe), pre-surgical anxiety, tetanus, porphyria, and several conduct disorders in children. Thorazine (chlorpromazine HCl) is approved to treat both adults and children for schizophrenia and bipolar disorder.
- Migraines Mainly in emergency rooms, where it is really effective.
- Managing the pain in blind eyes.
- Steroid-induced psychosis. AKA Roid rage.
- Augmenting AIDS treatments.
It’s cheaper than dirt, it’s effective, and it treats so many seemingly unrelated things (migraines, tetanus, AIDS) that it might help you reduce the number of other meds you need to take.
You’re more likely to be hit with a movement disorder like TD or EPS than you would be if you were taking AAPs of comparable potency - which means low dosages of most everything except Risperdal and Invega, where the risk is a lot higher. Unlike other standard/typical/first-generation APs (FGAs) the chance for weight gain isn’t that much less than atypical antipsychotics (AAPs) such as Zyprexa and Seroquel.
The usual that come with any antipsychotic: weird dreams, drowsiness and lethargy, a feeling of being disconnected from reality, emotional numbing, not really giving a damn. Put it all together and they add up to what is known as, “zombification.” Fortunately most of these tend to go away, at varying rates, usually within a matter of weeks.
Because Thorazine is such a potent antihistamine weight gain is a common side effect and the lethargy/daytime drowsiness doesn’t always go away, unlike most other FGAs.
Again, the same as most APs: movement disorders, the prolactin-related side effects of enlarged tits and/or surprise lactation (for both men and women), changes in menstruation, and assorted sexual dysfunctions including priapism. Before Viagra and Cialis this guy decided to take matters into his own hands, as it were. Only because I’m batshit crazy can I understand how crushing Thorazine tablets and shoving them up your urethra to deal with erectile dysfunction could seem like a good idea. Which it’s not.
Thorazine can result in a false positive for amphetamines in a urine test. As that was from 1992 the test may no longer be used, but this is why you really do need to list all the meds you take whenever you are required to pee in a cup.
You may have had Thorazine and never knew it. Some standard antipsychotics are given in emergency rooms every day as anti-nausea medications when their chemical cousins aren’t potent enough to stop the spenching, or aren’t available for one reason or another2.
Brain Cooties Aren’t Contagious
Medicated For Your Protection
We’re going to deal only with schizophrenia and mania, only for out-patients, and, as always, only adults. See the PI sheet for all the other situations and approved uses. Also, per the PI sheet, the dosages apply only to tablets and sustained-release Spansule capsules.
I really have to hand it to the guys at SmithKline Beecham (or whoever wrote the last PI sheet) for their honesty in admitting they have no clue as to what the dosages for the injections, oral concentrate, and suppositories really should be for long-term use:
Adjust dosage to individual and the severity of his condition, recognizing that the milligram for milligram potency relationship among all dosage forms has not been precisely established clinically. It is important to increase dosage until symptoms are controlled. Dosage should be increased more gradually in debilitated or emaciated patients. In continued therapy, gradually reduce dosage to the lowest effective maintenance level, after symptoms have been controlled for a reasonable period. —the Thorazine PI sheet
I’ve never read anything like that in a PI sheet. Their titration schedule is fairly sane:
Psychotic Disorders —Increase dosage gradually until symptoms are controlled. Maximum improvement may not be seen for weeks or even months. Continue optimum dosage [whenever the symptoms stop, usually in a range of 200–800mg a day] for 2 weeks; then gradually reduce dosage to the lowest effective maintenance level. Daily dosage of 200 mg is not unusual. Some patients require higher dosages (e.g., 800 mg daily is not uncommon in discharged mental patients).
OUTPATIENTS— Oral: 10 mg t.i.d. or q.i.d. [Three or four times a day], or 25 mg b.i.d. or t.i.d. [Two or three times a day
MORE SEVERE CASES— Oral: 25 mg t.i.d.
After 1 or 2 days, daily dosage may be increased by 20 to 50 mg at semiweekly intervals until patient becomes calm and cooperative.
PROMPT CONTROL OF SEVERE SYMPTOMS— I.M.[Intramuscular injection]: 25 mg (1 mL). If necessary, repeat in 1 hour. Subsequent doses should be oral, 25 to 50 mg t.i.d. —the Thorazine PI sheet
That “calm and cooperative” part is somewhat stereotypical. Not everyone in the lock ward, let alone outpatients, needs to be calmed down3 or forced into cooperation. Other than that the only quibble I have is a dosage increase twice a week, but only because that might be too fast for some people.
Thorazine is kind of slow for an antipsychotic. Like all antipsychotics it will do something within a day, sooner if injected, but it take up to a week before there’s a noticeable effect and, as it states in the PI sheet, it can take months before you know if Thorazine is going to fully control your symptoms or not.
I can personally attest that the effect on vomiting is nearly instant. Really. It’s TV-fast.
With most APs you can stop taking them rapidly, or immediately, in case of an emergency like a severe allergic reaction, and your ‘only’ real worry is rebound symptoms. Just as the sudden discontinuation of an antiepileptic drug can give you a seizure as a “rebound symptom” for something you don’t have, if you suddenly stop taking Thorazine (chlorpromazine) all at once you can get “rebound,” non-stop vomiting. Thorazine also has a reputation for severe rebound symptoms. Stahl recommends a 6–8 week discontinuation schedule, which is probably a bit long if you’re taking 200mg a day or less. If you’re taking 400mg a day or more, six-to-eight weeks seems about right, as you would want to reduce your dosage by 30–50mg a day every 3 to seven days.
Chlorpromazine’s half-life is anywhere from 8 to 33 hours, although it averages about four days for Thorazine to clear out of your system. Go figure.
Good question. Chlorpromazine’s pharmacokinetics are too variable to pin this down.

Based on the Communications Interference Hypothesis of psychiatric and neurological conditions (brain cooties, the crazies, etc.), Thorazine (along with all standard/typical/first-generation antipsychotics and most other APs) blocks the reception of excess dopamine at the D2 receptors to reduce the positive symptoms of schizophrenia and other psychoses, the manic side of bipolar, and similar conditions. Its antihistamine action combined with the dopamine blockade is why it works for anxiety and insomnia. The antihistamine and potent anticholinergic activity at specific receptors is what make Thorazine and other phenothiazines,4 so effective for nausea.
Your guess is as good as mine as to why Thorazine works for hiccups, tetanus, porphyria, HIV/AIDS, and even malaria.
While Prozac is probably the first med people think of when the subject of psychiatric medications comes up, when people think about the scary psych meds, Thorazine, the so-called “chemical straitjacket,” is the drug that scares the shit out of people who don’t know shit about psychiatric drugs. They need to shove a chlorpromazine suppository up their butts the next time they can’t stop puking and learn how it’s really not too bad.

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) A generic drug produced by a generics manufacturer that is a wholly-owned subsidiary of the company that makes the branded version. E.g. Greenstone Pharmaceuticals makes gabapentin, and they are owned by Pfizer, who also own Parke-Davis, the makers of Neurontin.
2) A branded generic is also a generic drug given a 'brand' name by the manufacturer (e.g. Teva's Budeprion), but otherwise has the same active ingredient as the original branded version (Wellbutrin).
3) A branded generic is also a generic drug given a 'brand' name by the manufacturer (e.g. Sanofi-Aventis' Aplenzin, which is bupropion hydrobromide) and uses a salt of the active ingredient that is different from the original branded version and other generics (Wellbutrin, Budeprion and all the others are bupropion hydrochloride). We aren't sure if that really makes a difference or not. The FDA says they're the same thing. As usual, the data are contradictory, but most evidence indicates that the FDA is right and the differences are negligible.
For our purposes a "branded generic name" refers to the second and third definitions.
2 Such as running out of money.
3 Although when I had a timeout in a psychiatric hospital's lock ward there were a few people who badly needed to be calmed down and made to cooperate, and a B-52 (Benadryl 5mg haloperidol 2mg lorazepam) sucks less for everyone involved than strapping them to a bed with someone always sitting next to them until a relative could be contacted or court order came through; as was the case with one poor bastard who looked and sounded like star of a low-budget exorcism movie.
4 There are a whole bunch of meds classified as phenothiazines that aren't crazy meds and are used in hospitals and prescribed as anti-emetics and super antihistamines. Phenergan (promethazine HCl) is one especially effective one with as many approved and off-label uses as Thorazine. It also works on migraine-induced nausea so quickly you'll want an IV kit at home, because as soon as it's hooked up to the drip the spenching stops and you're ready to fall asleep.

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

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 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 as anonymity on teh Intergoogles. 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.
