Did fluvoxamine treat COVID-19?
Fluvoxamine drew attention in 2020–2021 because it acts on the sigma-1 receptor, which may dampen inflammation. The large TOGETHER trial (Lancet Global Health, 2022) reported fewer emergency visits and hospitalizations with fluvoxamine. Other trials, including ACTIV-6, found no meaningful benefit. In 2022 the FDA declined to authorize it for COVID-19. It remains an OCD medication. It isn’t a COVID treatment, and it shouldn’t be taken for that without a clinician.
The drug that changes other drugs
Every SSRI raises serotonin. What makes fluvoxamine different is what it does to the liver enzymes that clear other medicines. It strongly blocks CYP1A2 and CYP2C19, which few other SSRIs do, so drugs that depend on those enzymes can build up to toxic levels.
Never combine (contraindicated):
| Drug | Why |
|---|---|
| Tizanidine (muscle relaxant) | CYP1A2 blocked. Tizanidine levels rise many times over, causing severe low blood pressure and sedation |
| Ramelteon (Rozerem, sleep aid) | CYP1A2 blocked. Ramelteon levels rise dramatically |
| Alosetron (IBS medicine) | CYP1A2 blocked |
| Thioridazine, pimozide (antipsychotics) | Higher levels lead to dangerous heart-rhythm (QT) effects |
| MAO inhibitors, including linezolid and IV methylene blue | Serotonin syndrome. Allow a 14-day gap |
Dose adjustment or close monitoring needed:
| Drug | What happens | Typical action |
|---|---|---|
| Theophylline | Levels rise sharply | Label: cut the theophylline dose to about one-third and monitor levels |
| Warfarin | Levels rise, raising bleeding risk | Monitor INR closely |
| Clozapine, olanzapine | Levels rise | Lower the dose and monitor |
| Some benzodiazepines (alprazolam, diazepam, midazolam, triazolam) | Levels rise, with more sedation | Lower the dose. The label says to avoid diazepam |
| Methadone (methadone) | Levels rise | Watch for sedation and breathing problems |
| Some tricyclic antidepressants | Levels rise | Lower the dose |
| Propranolol, some calcium-channel blockers | Levels rise | Monitor heart rate and blood pressure |
| Tramadol, triptans, lithium, St. John’s wort, other antidepressants | Serotonin syndrome risk | Use with caution |
| NSAIDs, aspirin, anticoagulants | Bleeding risk | Watch for bruising and GI bleeding |
Coffee, tea and cigarettes
Two everyday substances interact with fluvoxamine:
- Caffeine is cleared almost entirely by CYP1A2. On fluvoxamine, caffeine clearance drops dramatically, by roughly 90% in label studies, and its half-life can stretch from a few hours to more than a day. Your usual coffee can cause jitteriness, a racing heart, anxiety or insomnia that looks like a side effect of the medicine. Many prescribers advise cutting back.
- Smoking does the opposite. Tobacco smoke speeds up CYP1A2, and the label reports about 25% faster fluvoxamine clearance in smokers. Quitting while on fluvoxamine (and clozapine or olanzapine, if also taken) can raise drug levels, so tell your prescriber if you quit.
What it’s approved for, and what it isn’t
