sertraline
10 interactions related to sertraline
sertraline + st. john's wort
Sertraline is an SSRI that blocks serotonin reuptake, and St. John's wort independently raises central serotonin through constituents such as hyperforin and hypericin. Combining them can trigger serotonin syndrome, a potentially life-threatening reaction marked by altered mental status, autonomic instability, and neuromuscular hyperactivity. St. John's wort also induces CYP3A4 and CYP2C19, which can lower sertraline levels and undermine treatment.
sertraline + 5-htp
Sertraline blocks serotonin reuptake and 5-HTP (5-hydroxytryptophan) is the immediate precursor of serotonin, so it directly increases serotonin synthesis. Combining the two stacks production and reuptake blockade, which can precipitate serotonin syndrome.
sertraline + kava
Kava (Piper methysticum) is a central nervous system depressant with a documented risk of serious liver injury, and combining it with sertraline raises the chance of additive sedation and additive liver stress. Kava also inhibits drug-metabolizing enzymes, and a case report describes prolonged serotonin syndrome in a patient taking kava alongside a serotonergic antidepressant.
sertraline + sam-e
SAM-e (S-adenosyl-L-methionine) has its own antidepressant and serotonergic activity, so combining it with the SSRI sertraline can add serotonergic effects on top of each other. Case reports describe serotonin-toxicity-like presentations and treatment-emergent mania in patients combining SAM-e with serotonergic antidepressants.
caffeine + sertraline
Caffeine and sertraline do not share a receptor, but their side-effect profiles overlap. Both can cause anxiety, jitteriness, insomnia, stomach upset and headache, so these symptoms can stack — most noticeably during the first few weeks of sertraline treatment. Unlike fluvoxamine, sertraline does not meaningfully slow caffeine clearance.
cbd + sertraline
CBD inhibits CYP2C19, one of several enzymes that help break down sertraline, so adding CBD can raise sertraline exposure. A single published case report describes low sodium (hyponatremia) and cognitive decline in an older intermediate-metabolizer patient who added over-the-counter CBD to long-standing sertraline. The evidence is limited to this one report, so treat it as a reason for caution and prescriber discussion rather than a strong contraindication.
cannabis + ssris
Cannabinoids inhibit liver enzymes (including CYP2C19) that clear several SSRIs such as sertraline, citalopram, and escitalopram, which can raise SSRI plasma levels. Cannabinoids also touch the serotonin system, and case reports describe serotonin syndrome precipitated by high-potency cannabis in patients on serotonergic regimens.
coffee + sertraline
Sertraline is a weak inhibitor of CYP1A2, the enzyme that clears caffeine, so it can slow caffeine metabolism mildly. More relevant in practice, caffeine can add to the jitteriness, palpitations, anxiety, and insomnia that often appear in the first weeks of sertraline. The pharmacokinetic effect is far smaller than with fluvoxamine and is usually minor.
alcohol + sertraline
Sertraline (Zoloft) and alcohol both act on the central nervous system. Controlled studies in healthy volunteers did not show sertraline worsening alcohol's effects on thinking or coordination, but the FDA label still advises against drinking on sertraline because alcohol can deepen depression and anxiety, worsen drowsiness and sleep, and blunt the medication's benefit in people being treated for a mood disorder.
sertraline + tryptophan
Sertraline is a selective serotonin reuptake inhibitor (SSRI) that increases serotonin signaling, and L-tryptophan is the dietary precursor your body converts into serotonin. Taking them together can push serotonergic activity too high, raising the risk of serotonin syndrome (agitation, tremor, sweating, fast heart rate, and in severe cases fever, rigidity, and seizures).
