Evidence of interactionPending medical review

The short answer

Possibly. Doctors in Kraków, Poland, reviewed adverse-event reports and found a few that they judged were probably caused by ashwagandha taken with an antidepressant. These included severe diarrhoea with sertraline, nausea, vomiting and muscle pain with escitalopram, and muscle and eye pain with paroxetine.

These are single reports, and they cannot show how often this happens. A small trial in Iran gave ashwagandha to people already on SSRIs and recorded no side effects, but it lasted only six weeks. If you take an SSRI or SNRI, tell your prescribing doctor before you start ashwagandha, and report any new stomach, muscle or eye symptoms.

Sold in India as Nexito (escitalopram), Fludac (fluoxetine), Duzela (duloxetine) and Venlor (venlafaxine).

The evidence, study by study

Review of adverse-event reports, Poland, 2023 Case report

Doctors in Kraków reviewed 1,816 adverse-event reports and found 30 that were probably caused by an adaptogen herb taken with an antidepressant. The ashwagandha reports involved sertraline (severe diarrhoea), escitalopram (muscle pain, stomach pain, nausea, vomiting, restless legs and a severe cough) and paroxetine (widespread muscle pain, eye pain and raised eye pressure). One more involved reboxetine, another antidepressant. Reports like these cannot give a rate, and other medicines may have played a part.[1]

Case summarised by Memorial Sloan Kettering Case report

The cancer centre's herb monograph lists a 47-year-old woman who developed reversible cerebral vasoconstriction syndrome, a temporary narrowing of blood vessels in the brain. She had used ashwagandha, medical marijuana and an SNRI antidepressant. Her symptoms resolved with treatment. With three exposures, no single cause can be named.[2]

Trial in obsessive-compulsive disorder, Iran, 2016 RCT

At Mashhad University of Medical Sciences, 30 people with OCD who were all taking SSRIs added ashwagandha root extract (120 mg a day) or a placebo for six weeks. OCD scores fell further with ashwagandha (median change -8 against -2), and no side effects were reported. With 15 people on ashwagandha, the trial was far too small to pick up uncommon problems.[3]

Laboratory study, United States, 2025 In vitro

At Auburn University, four extracts of ashwagandha root and leaf were tested against seven liver enzymes that clear many medicines. None blocked them in a reversible way at the strengths tested. This does not cover enzyme induction or effects on the brain.[4]

Case series, India, 2023 Case report

Liver specialists at several Indian centres described 8 people with liver injury after single-herb ashwagandha products. Five already had chronic liver disease, and three of them developed acute-on-chronic liver failure and died. This is about ashwagandha's own risk to the liver, not about antidepressants.[5]

What your doctor may watch for

New diarrhoea, nausea or vomiting, muscle pain, or eye pain after starting ashwagandha.[1]
Yellow eyes or skin, dark urine or itching, which can be signs of liver injury.[5]

What to tell your prescribing doctor

You can read this out, or show them this page:

“I am taking, or planning to take, ashwagandha (name of product, form and how much) along with my antidepressant. Doctors have reported side effects with ashwagandha and sertraline, escitalopram or paroxetine. Is this combination a concern for me, and what should I watch for?”

Questions people ask

Can ashwagandha replace my antidepressant?

No study supports that. In the Iranian trial, ashwagandha was added to SSRIs, not used instead of them. Any change to an antidepressant is for your prescribing doctor to decide.[3]

Does it matter which antidepressant I take?

The reports we found involved sertraline, escitalopram and paroxetine, and one case involved an SNRI. Nobody has compared antidepressants for this, so the absence of a report for your medicine tells you nothing either way.[1][2]
