Fluvoxamine (Luvox) Side Effects and Uses
A plain-language guide to Fluvoxamine, an SSRI antidepressant. Learn how it helps, what it treats, how to take it and which side effects to know about.
Quick answer. Fluvoxamine (Luvox) is an SSRI antidepressant. Common fluvoxamine side effects include nausea, sleepiness or feeling sedated, trouble sleeping and dry mouth. The rare but serious ones, and when to get help, are listed under fluvoxamine side effects below. Never stop or change your dose on your own.
How Fluvoxamine Can Help You
Fluvoxamine (Luvox) is an SSRI with a special place in treating OCD. In the United States, OCD is its FDA-approved use. It raises serotonin signaling. Over time, intrusive thoughts get weaker and less frequent. It also weakens the urge to repeat rituals.
That gives people room to take part in therapy. They can win back time lost to OCD. It can also ease depression and anxiety.
OCD usually responds more slowly than depression, so patience matters. Real change often takes six to 12 weeks. Your prescriber raises the dose step by step and tracks your response. The medicine is often paired with therapy made for OCD. Together, they tend to work better than either one alone.
Uses for Fluvoxamine
- Obsessive-compulsive disorder (OCD), in adults and children 8 and older
- Social anxiety disorder (off-label)
- Major depressive disorder (off-label)
- Panic disorder (off-label)
- Post-traumatic stress disorder (off-label)
- Generalized anxiety disorder (off-label)
How to Take Fluvoxamine
Your prescriber decides your dose and how fast to raise it. It can make you sleepy. So it is often started at bedtime. At higher amounts, it may be split into two doses a day. You can take it with or without food.
Take it at the same times each day. Missed a dose? Take it when you remember, unless the next dose is close. Then skip it and do not double up. Do not stop fluvoxamine suddenly. Fluvoxamine has more drug interactions than most SSRIs. Keep your prescriber up to date on every medicine and supplement.

How Fluvoxamine Works
Like other SSRIs, fluvoxamine slows the reuptake of serotonin. More serotonin stays active, and over weeks the brain adapts. In OCD, this can turn down obsessions. Rituals get easier to resist.
Fluvoxamine also slows some liver enzymes. These enzymes break down other drugs. So it can raise the levels of other drugs. Examples are caffeine, theophylline, warfarin and clozapine. That is why your prescriber asks about everything you take.
Before You Start Fluvoxamine
Some drugs must never be taken with fluvoxamine. They include MAOI antidepressants, tizanidine, thioridazine, pimozide, alosetron and ramelteon. Other drugs that raise serotonin add to the risk of serotonin syndrome. Aspirin, NSAIDs and blood thinners raise bleeding risk. Fluvoxamine makes caffeine last longer. So you may need to cut back on caffeine.
Share any history of bipolar disorder, seizures, liver disease or glaucoma. Like all antidepressants, it has a boxed warning. It covers suicidal thoughts in young people.

FAQ
Questions About Fluvoxamine
Why is fluvoxamine used mainly for OCD?
In the United States, fluvoxamine is FDA approved for OCD. Strong research backs that use. It is an SSRI like sertraline or fluoxetine, so it can also help depression and anxiety. Other SSRIs are more often chosen for those conditions.
Why does my prescriber ask so much about my other medications?
Fluvoxamine slows some liver enzymes. This can raise the levels of other drugs a lot. Examples include caffeine, some sleep medicines, some blood thinners and clozapine. A full list of your medicines and supplements helps your prescriber avoid risky combinations.
How long does fluvoxamine take to help OCD?
OCD tends to respond more slowly than depression. Expect six to 12 weeks for real change, and gradual dose increases are normal. Pairing the medicine with therapy made for OCD, often called exposure and response prevention, tends to give the best results.
Will fluvoxamine make me sleepy?
It can, which is why it is often started at bedtime. For many people this eases with time. If daytime sleepiness lasts, your prescriber can change the timing or how the dose is split.
Can I stop once my OCD symptoms improve?
OCD often comes back if the medicine is stopped too soon. Most prescribers suggest staying on it for a long time after you improve, often a year or more. When it is time to stop, a slow taper with close follow-up is the safest way.
Can children take fluvoxamine?
Yes. Fluvoxamine is FDA approved for OCD in children 8 and older. Young people on any antidepressant need close follow-up because of the boxed warning about suicidal thoughts.
Should I cut back on coffee while taking fluvoxamine?
Often, yes. Fluvoxamine slows how fast your body clears caffeine, so coffee, tea and energy drinks can hit harder and last longer. You may notice jitters or poor sleep. Ask your prescriber how much is reasonable for you.
Can I drink alcohol while taking fluvoxamine?
It is best to limit or avoid alcohol. Alcohol can worsen anxiety and mood, and it may add to drowsiness. Talk with your prescriber about what is safe for you.
