Drug & supplement interaction

Asafoetida + Latanoprost

Latanoprost brand names: Xalatan, Xelpros, Iyuzeh.

No Known Interaction
The bottom line No known interaction

We found no known interaction between Asafoetida and Latanoprost 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.

Asafoetida and Latanoprost

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 Latanoprost and Asafoetida 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.

What to actually watch for

No Interaction Found — But Data Suggests Asafoetida and Latanoprost 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.

  • A fast or pounding heartbeat Additional detail

    Asafoetida

    “Orally, asafoetida has been associated with methemoglobinemia in infants (4,102549). In one case, a 3-month-old boy who was given asafoetida gum resin for colic presented with tachypnea, hypoxia, and tachycardia. The child had very high methemoglobin levels and other markers consistent with metabolic acidosis with lethal methemoglobinemia.”

About Asafoetida

What is Asafoetida?

Asafoetida
  • Digestive upset and gas
  • Bloating and stomach cramps
  • Irritable bowel symptoms
  • Respiratory complaints
  • Used as a cooking spice

Asafoetida is a strong-smelling plant resin used widely as a spice and in traditional medicine, mainly for digestive complaints. Solid human evidence for its medicinal benefits is limited, though it is generally considered safe in the small amounts used in cooking. Talk with your pharmacist or doctor before using concentrated supplements, and avoid them during pregnancy and breastfeeding.

Ferula assa-foetida · Apiaceae · Dried gum resin (oleo-gum-resin) from the root and rhizome · Powder, capsules, resin, tincture/extract, culinary spice

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

Asafoetida: dosing

There is no official, standardized medicinal dose for asafoetida. The amount used can vary widely between products and traditional recipes, and high-quality dosing studies in people are lacking.As a cooking spice, only a small pinch of powder is typically used.

From our Asafoetida monograph — the full record covers uses, side effects and every documented interaction.

About Latanoprost Ophthalmic

What Is Latanoprost Ophthalmic Used For?

Brand names: Xalatan, Xelpros, Iyuzeh

Latanoprost ophthalmic solution — available as Xalatan, Xelpros, and Iyuzeh — is used to reduce elevated intraocular pressure (IOP, the pressure inside your eye) in people with open-angle glaucoma or ocular hypertension (high eye pressure without glaucoma symptoms yet). Keeping eye pressure under control is important because high pressure is a major risk factor for damage to the optic nerve and loss of vision.

Taking Asafoetida and Latanoprost Together: Common Questions

Is it safe to take Asafoetida with Latanoprost?
We do not list a known interaction between Asafoetida and Latanoprost. 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 Asafoetida and Latanoprost have any of the same side effects?
Yes — our sources link each of them separately to 3 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.
Does Asafoetida interact with any other medications?
Yes. Asafoetida has 289 documented drug interactions in our database — Latanoprost is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
