Coriander and Deserpidine, Methyclothiazide

These two interact in 2 distinct ways. Each one is explained separately below.

Why Are There 2 Interactions?

Coriander interacts with whole categories of medication. Deserpidine, Methyclothiazide falls into 2 of those categories, so it can interact with Coriander in 2 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Moderate).

Moderate

ANTIHYPERTENSIVE DRUGS

1 of 2

Why this applies to Deserpidine, Methyclothiazide

Deserpidine, Methyclothiazide falls under ANTIHYPERTENSIVE DRUGS — the group Coriander interacts with.

Theoretically, coriander might increase the risk of hypotension when taken with antihypertensive drugs.
Evidence from animal research suggests that coriander fruit can lower blood pressure.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Your Enduronyl combines deserpidine (which calms the nervous system signals that raise blood pressure) with methyclothiazide (a water pill). Both already work to bring your numbers down. The thinking here is that coriander, based on animal studies, may also gently lower blood pressure. So stacking the two together could, in theory, push your pressure a little lower than expected.

If that happened, you might feel dizzy, lightheaded, or tired, especially when standing up quickly. I want to be honest though: this is theoretical and only comes from lab and animal research, not human studies. The cilantro you sprinkle on tacos is very unlikely to matter. Concentrated extracts or essential oils are a different story, so check with your pharmacist before using those.

PHOTOSENSITIZING DRUGS

2 of 2

Deserpidine, Methyclothiazide also falls under PHOTOSENSITIZING DRUGS.

Theoretically, coriander might increase the risk of photosensitivity when taken with photosensitizing drugs.
Evidence from in vitro research suggests that coriandrin, a constituent of coriander, has photosensitizing effects.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the gist: Enduronyl combines deserpidine with methyclothiazide, a thiazide-type water pill. Like other thiazide diuretics, methyclothiazide can make your skin more sensitive to sunlight, so you may sunburn faster than usual. Coriander contains a compound called coriandrin that, at least in lab studies, may also make skin react more to UV light. Put them together and, in theory, you could be a bit more prone to sunburn or a sun rash.

I want to keep this in perspective. This is a theoretical concern based on test-tube research, and the cilantro you cook with is very unlikely to cause trouble. Concentrated coriander extracts or essential oils are the bigger question mark. Just use good sun protection, and check with your pharmacist or doctor before starting any coriander supplement.
