Drug & supplement interaction

Watercress + Sertraline

Sertraline brand name: Zoloft.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Watercress and Sertraline in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first. Additionally, although there is no interaction, the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Watercress and Sertraline

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Sertraline and Watercress in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

How we checked

Why No Interaction Is Listed for Sertraline

Interactions in our licensed database are recorded against drug classes, not just single drug names. Sertraline is filed under 13 classifications — including antidepressant drugs, cytochrome p450 2c19 (cyp2c19) inhibitors, cytochrome p450 2c9 (cyp2c9) inhibitors. Watercress has documented interactions with 3 drug classes — the most serious being chlorzoxazone (parafon forte, paraflex) (moderate), lithium (moderate) and warfarin (coumadin) (moderate) — and none of Sertraline’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

What to actually watch for

No Interaction Found — But Data Suggests Watercress and Sertraline May Share Several of the Same Side Effects

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do.

  • Fever / Stomach pain / Diarrhea / Vomiting reported in 4.7% of FDA reports for Sertraline Additional detail

    Watercress

    “Raw, wild watercress can be contaminated with parasitic flukes which, when ingested, cause the liver disease fascioliasis. Symptoms include abdominal pain, fever, vomiting, diarrhea, urticaria, eosinophilia, and hepatomegaly. Clinical research shows that taking a standardized extract of watercress orally 750 mg/kg daily for 5 weeks is not associated with increases in liver function enzymes.”

    Sertraline

    Listed in the ADVERSE REACTIONS section of the FDA label for Sertraline, and in voluntary FDA adverse-event reports. Read the label on DailyMed ›

Reported for Watercress but not commonly for Sertraline: kidney problems, a skin rash, hives and itching.

Effects for Sertraline come from the ADVERSE REACTIONS section of its FDA label; effects for Watercress come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 214,799 voluntary FDA FAERS reports for Sertraline that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

About Watercress

What is Watercress?

Watercress
  • Source of vitamins and minerals
  • Antioxidant support
  • General nutrition
  • Traditional cough and congestion remedy
  • Skin and detox tonics

Watercress is a nutrient-rich leafy green that provides vitamins A, C, and K plus minerals and antioxidant plant compounds. Eaten as a food it is generally safe and healthy for most people, but strong human evidence for concentrated supplement health claims is limited. Talk to your pharmacist or doctor before using high-dose extracts, especially if you are pregnant, breastfeeding, or have a medical condition.

Nasturtium officinale · Brassicaceae · Leaves and stems (above-ground parts) · Fresh leafy green, salad, juice, extract capsules, dried herb

An interaction check asks whether these two react with each other — it does not ask whether Watercress is a good idea for someone in your situation. Here is what our Watercress record says about it on its own.

Watercress: dosing

There is no official or standardized dose for watercress as a supplement. As a food, it is simply eaten in salads or cooked dishes in the amount you enjoy.For capsules, powders, or extracts, follow the directions on the product label, since strength varies between products. More is not always better, and concentrated extracts have not been well studied for safety.

About Sertraline

What Is Sertraline Used For?

Brand name: Zoloft

Sertraline treats a range of mental health conditions. All formulations are approved for major depressive disorder (MDD) in adults and obsessive-compulsive disorder (OCD). The oral solution (including Zoloft oral solution) and several tablet formulations are also approved for panic disorder, post-traumatic stress disorder (PTSD), social anxiety disorder, and premenstrual dysphoric disorder (PMDD).

For OCD specifically, the capsule formulations and some tablet products are approved for use in adults and children aged 6 and older. Sertraline hydrochloride tablets (plain, not film-coated) are approved for OCD in pediatric patients as well. However, sertraline is not approved for major depressive disorder in children — only in adults.

Taking Watercress and Sertraline Together: Common Questions

Is it safe to take Watercress with Sertraline?
We do not list a known interaction between Watercress and Sertraline. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Do Watercress and Sertraline have any of the same side effects?
Yes — our sources link each of them separately to 4 of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
How was the Watercress and Sertraline combination checked?
Interactions in our licensed database are recorded against drug classes. Sertraline is filed under 13 classifications, and Watercress has documented interactions with 3 drug classes — none of Sertraline's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Watercress interact with any other medications?
Yes. Watercress has 6 documented drug interactions in our database — Sertraline is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Sertraline interact with any supplements?
Yes. Sertraline has documented interactions with 188 supplements in our database — Watercress is not one of them. The Sertraline interaction page linked on this page lists every one, ranked by severity.
