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

We found no known interaction between Tomato and Citalopram 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.

Tomato and Citalopram

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 Citalopram and Tomato 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.

Worth understanding: our licensed dataset holds no drug-interaction record for Tomato at all — not against Citalopram, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

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.

What to actually watch for

What Tomato Itself Has Been Linked To

This is not an interaction — nothing below involves Citalopram. It is the side-effect record for Tomato on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Tomato, this list is the first place to look. One entry is worth acting on rather than waiting out — marked below.

  • A slow heartbeat Worth acting on Additional detail

    “Orally, tomato leaves and ripe or unripe tomato fruit are well tolerated in typical food amounts. Tomato extracts also seem to be well tolerated. Tomatine, a glycoalkaloid found in tomato leaves and unripe green tomatoes, can cause serious side effects when consumed in excessive amounts.

    Serious Adverse Effects (Rare):

    Orally: Bradycardia, diarrhea, respiratory disturbances, spasms, vomiting, and death with excessive…”

    Tomato · Natural Medicines adverse-effect record, reported in diarrhea.

  • Dizziness / Headache Additional detail

    “Orally, the glycoalkaloid tomatine in tomato leaf or green tomatoes can cause dizziness, stupor, headache, and mild spasms when consumed in excessive amounts (18,102957).”

Everything above comes from the Natural Medicines adverse-effect record for Tomato — expand a row for the licensed statement it rests on. We read the ADVERSE REACTIONS section of Citalopram’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Citalopram column appears here.

Pregnancy And Lactation Likely Safe

About Tomato

What is Tomato?

  • Heart health support
  • Prostate health
  • Antioxidant support
  • Skin protection from sun damage
  • General nutrition

Tomato is a common food rich in vitamins, potassium, and the antioxidant lycopene, and eating it as part of a balanced diet is healthy for most people. Concentrated tomato or lycopene supplements are marketed for heart and prostate health, but the evidence is mixed and far from proven. Talk to your pharmacist or doctor before using high-dose supplements, especially if you are pregnant or have a medical condition.

Solanum lycopersicum · Solanaceae · Fruit (and extracts such as lycopene from the fruit and skin) · Whole fruit, juice, paste, tomato extract capsules, lycopene supplements

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

Tomato: dosing

There is no official standardized dose of tomato or lycopene supplements, and a proven effective amount has not been established. Tomatoes are best enjoyed simply as part of a balanced diet.If you choose to use a tomato extract or lycopene supplement, follow the directions on the product label and do not exceed the recommended amount.
