Citation needed

This:

"Although its effects are similar to other SSRIs, fluvoxamine has different pharmacological effects. For this reason, fluvoxamine can be of benefit to patients who experience unusual or limiting side-effects from other antidepressants. Fluvoxamine also appears to cause fewer side-effects than other SSRIs, particularly in relation to loss of sex-drive."

definitely needs a citation. Otherwise, this claim is only some PR try for fluvoxamine.--Spiperon 22:00, 15 October 2006 (UTC)

I searched for this sentence on google and it is present on many pages (67). Don't have anything for definitive citation though. -- Amit 14:26, 3 July 2007 (UTC)

"Sales fell, and Solvay withdrew the medication from the U.S. market in 2002 to prevent further investigation which might have revealed that at least one homicide had occurred among participants during Fluvoxamine's Phase III Clinical Trials prior to FDA approval." This also really needs a citation. I've tagged it for now. 98.220.2.29 (talk) 16:08, 4 September 2009 (UTC)

Cleanup, references and WP:NPOV

I've been working on the drug interaction section plus some other cleanup here and there but other sections need attention, especially for references. Please be aware that there seems to be a general tendency to WP:SYN in this sort of article so we do need to take the time to document our sources. I put flagged two sections I think need references the most. I didn't flag the article with a POV notice as the prose could be a writing stylism. Or is it POV?Trilobitealive (talk) 22:47, 1 February 2008 (UTC)

Historical relevance

I removed the historical relevance section, because it didn't cite the key claims (about Columbine and the alleged homicide during a trial). It can be put back with citations to reliable sources. Superm401 - Talk 20:56, 2 March 2008 (UTC)

The article as written seems to imply that Jazz and IVAX are the only manufacturers of both Fluvoxamine and Luvox. However, ANI Pharmaceuticals also manufactures both. [1] --64.77.218.74 (talk) 03:45, 5 January 2010 (UTC)

Paedophilia

The reference that Fluvoxamine has been used to "treat" paedophilia strikes me as particularly odd. Since paedophilia is not a disease per se, it seems a little strange to say Fluvoxamine is used to treat it. Maybe some sort of qualification is in order. As an analogy, imagine if one were to write in the article on EST that it is commonly used to treat Homosexuailty. I am not questioning that there are paedophiles who are taking Fluvoxamine to try to adjust their psychology and sexuality, just that it seems strange to call it a "treatment" without first making the assumption that paraphilia are treatable medical conditions. 76.105.4.183 (talk) 06:36, 5 March 2010 (UTC)

Fluvoxamine connected to circadian rhythm sleep disorders, as distinguished from other SSRIs.

Summary: According to the abstract appended below, fluvoxamine usage may induce circadian rhythm sleep disorders (CRSD), unlike some other SSRIs.

Relevance: It is important to include CRSD as a potential side effect due to its debilitating effects and the difficulty of its treatment. Awareness of this study could suggest a simple solution for those affected to try: namely, the substitution of a different SSRI.

Request: My Wikipedia edits have primarily been grammar/punctuation so I don't feel confident editing pharmacology content. Therefore, I'm submitting this information for you to act upon as you see fit.

The Abstract:

Circadian rhythm sleep disorders as a possible side effect of fluvoxamine by Hermesh H1, Lemberg H, Abadi J, Dagan Y. CNS Spectr. 2001 Jun ;6(6):511-3. http://www.ncbi.nlm.nih.gov/pubmed/15744215/

Sleep problems, day somnolence, and fatigue as a result of psychotropic drugs are very common. Psychiatrists usually consider these effects a result of insomnia and treat them by prescribing sleeping pills or other benzodiazepine agents. We describe here 10 cases of circadian rhythm sleep disorders (CRSD)--and not merely insomnia--as a possible side effect of fluvoxamine (FVA). Two other serotonin reuptake inhibitors, fluoxetine and clomipramine, did not induce CRSD in any of these 10 patients. We speculate that FVA-induced CRSD is caused by the effect of FVA on serotonin and melatonin levels in the central nervous system. CRSD as a side effect of FVA can be treated by replacing the suspected FVA or adding melatonin to a beneficial FVA treatment. Thus, it is important to be aware of possible iatrogenic CRSD in order to treat appropriately. Prospective studies are needed to confirm our observation and to study the influence of other psychotropic drugs on sleep-wake schedule.

Five healthy volunteers ingested a single dose of 5 mg melatonin. One week later they were given a single dose of 50 mg fluvoxamine with or without an additional dose of 5 mg melatonin after three hours. Coadministration of fluvoxamine led to a 23-fold higher (p<0.05) area under concentration-time curve (AUC) (6.2 to 141.3 mg/h/L and a 12-fold higher (p<0.01) serum peak concentration (Cmax) (2.18 to 25.1 ng/mL) of melatonin (1).

Serum profiles of melatonin were studied in a 51 year-old patient, without drugs, under separate administration of fluvoxamine and melatonin and under combined treatment. Administration of 75 mg fluvoxamine and 5 mg melatonin increased the availability of melatonin 20-fold (2).

• Melatonin therapy of 5 mg/day taken simultaneously with FVA=Fluvoxamine restored the sleep-wake cycle to its normal rhythm in 2 out of 4 therapeutic trials
• The lowest dose of FVA that was associated with delayed DSPS = sleep-phase syndrome was 100 mg/day. (So use 50mg/day).
• FVA was withdrawn. 10 days later, the DSPS completely disappeared; however, a mild depression was apparent and her OCD was significantly exacerbated. Readministration of FVA 100 mg/day resulted in a similar delayed sleep-wake phenomenon within a week from commencement.

Countries

"although in other countries", says the Medical Uses section. Countries other than what? I assume this is a reference to the FDA thing, and I also assume that the FDA thing is North American, but it's a bit unclear. —Vom ^(talk) 15:08, 5 May 2016 (UTC)

Vom: The FDA stands for the "Food and Drug Administration" and is actually referenced earlier in the article when discussing the black box warning. It is an agency of the United States government which regulates and categorizes (we use the term "Schedule" to describe categories of) pharmaceuticals. So yes, it's "North American" but specifically the United States of America. I think because this is the English Wikipedia page, it may have been written by an American, and this reference is for American readers. If you think we should change this, perhaps we should make it something like, "While the United States FDA has only approved this drug for the treatment of OCD, it is approved for use by *insert other nations' regulating agencies* (in Austrailia, the Russian Federation, and UK respectively) for also treating major depressive disorder."

Fluoride content and bioavailability of Fluoride from Fluvoxamine, compared to fluoride from drinking water and food?

I calculated that 50mg tablet of Fluvoxamine contains the following amount of fluoride:

https://pubchem.ncbi.nlm.nih.gov/compound/Fluvoxamine

• Molar mass of Fluvoxamine = 318.33

• Molar mass of Fluoride = 19

• Number of Fluoride atoms in Fluvoxamine = 3

(3*19)/318.33*50mg = 9mg fluoride.

Or less, if Fluvoxamine is salt of something that pubchem doesn't include in molar mass?

In Finland the average total intake of fluoride from water, food and toothpaste is only 0.6mg/day, although it is higher in areas were drinking water contains more fluoride. 80-85% comes from food. 90% of ingested fluoride is absorbed from gut:

https://thl.fi/fi/web/ymparistoterveys/vesi/kaivovesi/kaivoveden-kemiallinen-laatu/kaivovedessa-luonnostaan-esiintyvat-kemialliset-aineet/fluoridi

Intake of Iodine should be increased somewhat when taking Fluvoxamine, because Fluoride and Iodine are both in group 17 of periocal table of elements, but I don't know the details. So I would supplement with at least 100% RDA of Iodine with FluvoxAmine.

Iodine and some medicines containing fluoride are mentioned here without scientific references: https://www.sun-sentinel.com/health/fl-xpm-2013-12-27-fl-suzy-cohen-122913-20131219-story.html

Information on use for treating COVID

All the information I added on the FLV use in COVID on December 23 was removed shortly thereafter. Yet the information was all based on reliable sources including a JAMA article which has been viewed over 120,000. How is that not relevant medical information? All the other sources are reliable medical information, or are directly from recognized experts, and nothing there was not supported by solid scientific evidence. This is a huge disservice to the world to remove this, so I am baffled by the removal. Please explain the benefit to removing this lifesaving information. Thanks!

What an obtuse, intractable standard. This isn't speculative science; these effects are being replicated as we speak. Let's at least allow language on the wiki that acknowledges the preliminary nature of these trials whilst maintaining the central claim that Luvox has demonstrated noteworthy effects. Frevangelion (talk) 15:19, 4 February 2021 (UTC)

Could we, perhaps, treat it as a media phenomenon and reflect in the Society and culture section? Something along the lines: media promotes fluvoxamine for the treament of COVID-19, while not a single double blind trial has been tun.

Hi there, this page cites this paper (Full text available via scihub.) for Fluvoxamine being a moderate CYP2D6 inhibitor meanwhile the page for CYP2D6 cites this link stating it's a weak CYP2D6 inhibitor.
