2. FDA Approved Uses of Luvox (fluvoxamine) / Luvox CR
3. Off-Label Uses of Luvox
- Luvox (fluvoxamine) is approved to treat depression pretty much everywhere else in the world.
- Generalized social anxiety
- Premenstrual Dysphoric Disorder
- Binge eating - two studies, one big and one small indicate that SSRIs just aren’t much good for binge eating.
- Combat PTSD
- Musical hallucinations in acquired deafness
4. Luvox / Luvox CR pros and cons
- Proven as the best med for OCD.
- Generally less agitating than other SSRIs.
- Tends to work faster than other SSRIs, except Lexapro.
- The short half-life can make discontinuation difficult.
- It doesn’t have as many drug-drug interactions as Provigil or fish oil, but it’s as bad, if not worse than warfarin when it comes to the ones it does have. E.g. Luvox + Cymbalta = effectively tripling your Cymbalta dosage.
5. Luvox / Luvox CR Side Effects
5.1 Typical Luvox / Luvox CR Side Effects
The usual for SSRIs - headache, nausea, dry mouth, sweating, sleepiness or insomnia, and diarrhea or constipation, weight gain, loss of libido. Most everything will go away after a week or two, but the weight gain and loss of libido might stick around longer. Or permanently.
Agoraphobia, fecal incontinence, priapism. Time to stay inside and make the freakiest scat video ever!
- Mixing caffeine and Luvox (fluvoxamine) can be intensely unpleasant. Your one cup of joe will suddenly become like five cups, and the effects will last six times as long.
The results indicate that intake of caffeine during fluvoxamine treatment may lead to caffeine intoxication. —A fluvoxamine-caffeine interaction study.
- It’s not just coffee. Luvox can mess with a lot of meds, crazy or otherwise. As with Symbyax, if you take any other med for any reason be sure to talk with your pharmacist (this is exactly the sort of thing they teach in pharmacy school), read the Drug Interactions section of the PI sheet and the PI sheets of all the drugs you take, and enter everything (prescription or otherwise) at Check My Meds’ drug-drug and drug-food interaction site to make sure there is no nasty surprise.
- If you smoke you’ll increase the metabolism of Luvox (fluvoxamine) by 25% to 60%. That’s out of the PI sheet, with a study backing it up. So you’ll get less out of it. Somehow that’s ironic for a med that is officially approved only for OCD, as nicotine is an effective treatment for OCD. No, really, nicotine reduces OCD and various anxiety symptoms.
The initial dose is 50 mg at bedtime, increased by 50 mg a day every four to seven days as needed until the maximum dose of 300 mg a day is reached. Like any SSRI I suggest starting out with 25mg and then increasing to 50mg after a week. If you don’t feel anything go up to 100mg, but stay there until you’ve given it a try for a month total (about two weeks at 100mg), otherwise it’ll just be a pain in the ass to stop it. Even at 100mg you’ll know after a month if Luvox is going to do something for you.
Here Abbott & Jazz Pharma’s recommendation:
100 mg at bedtime, with weekly increases of 50 mg as tolerated to maximum therapeutic benefit, not to exceed 300 mg per day.--Luvox CR PI sheet
At least they kept Solvay’s lack of a target dosage. As much as I’d like to suggest starting at 50mg, as James pointed out, Luvox CR comes in only two dosages: 100mg & 150mg. So you’re pretty much stuck with starting at 100mg a day.
Like all SSRIs anywhere from a couple days to over a month. If you don’t feel any positive benefit after a two-three weeks, then you should talk to your doctor about either another SSRI and/or adding an antipsychotic to the mix.
Your doctor should be recommending that you reduce your dosage 25–50mg every 4 days if you need to stop taking it.
While you have the option of reducing your dosage by 50mg a day with the CR form, since Jazz Pharma makes Luvox CR only in 100mg and 150mg capsules, that can be both complicated and expensive. A study specific to fluvoxamine withdrawal shows that if you stop taking Luvox abruptly you might wind up with SSRI discontinuation syndrome. Ya think?
So if your discontinuation seems harsh, and because fluvoxamine has such a short half-life and its pharmacokinetics are non-linear, talk to your doctor about getting a prescription for immediate-release fluvoxamine and go for a tapering of 12.5–25mg a day.
With a half-life of 15.6 hours, the shortest of all true SSRIs4, Luvox (fluvoxamine) is out of your body in about 80 hours. Luvox CR has a half-life of about 16 hours, so there’s still not much difference.
The steady state for Luvox is non-linear. That means if you change the dosage, the steady state gets hosed. So Solvay doesn’t publish any steady state data. Figure at least a week, maybe two, after your last dosage adjustment.
Note that Luvox (fluvoxamine) is not technically an antidepressant in the US, just everywhere else. Luvox is just one of two meds of which I’m aware that are officially approved only for OCD in the US. And why is it so good for OCD? It’s all about the sigma-1 receptor, and fluvoxamine likes sigma-1. Zoloft is another meds that is especially effective for anxiety disorders, and it is also sigma-1 agonists.
Solvay may have given up on Luvox, but in 2008 Abbott & Jazz Pharma brought brand-name Luvox back to the US market as Luvox CR extended-release capsules. How CR translates to extended release is beyond me. I can understand why they didn’t want to call it Luvox ER, because that looks and sounds too much like Effexor, and Elan Pharma’s fancy Spheroidal Oral Drug Absorption System (or SODAS) must “controlled” and not “extended,” or something like that.
Luvox CR originally had approval to treat social anxiety disorder (SAnD) as well as OCD. Unfortunately some data from the clinical trials were made public and the FDA pressured Jazz to “voluntarily withdraw the indication”.5
We know that nicotine makes you clear Luvox a lot faster and nicotine is an effective treatment for OCD. So what would happen if a poor metabolizer of CYP1A2 substrates with OCD combined Luvox with nicotine. Synergistic effect or just a wash?

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 The term "branded generic" has three meanings:
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 DU 23000 - the designation used prior to the assignment of the generic name fluvoxamine - was being tested for depression as far back as 1977. Fevarin was released in Switzerland in 1984, although it wasn't approved in the US until 1993.
3 Which seems to be a common trait with sigma-1 agonists.
4 Paxil CR has a half-life of 15-20 hours, while the immediate-release form has a half-life of 21 hours. No, I don't have those backwards. Yes, it makes no sense to me either, other than drug companies usually do a half-assed job in PK testing.
5 And they had to file the usual shitload of paperwork that accompanies any change to what a medication is prescribed for, or anything else that is in a PI sheet for that matter. Talk about adding insult to injury.

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