Drug & supplement interaction

Inosine + Misoprostol

Misoprostol brand name: Cytotec.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Inosine and Misoprostol 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 label for Misoprostol states a food rule worth keeping to, and 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.

Inosine and Misoprostol

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 Misoprostol and Inosine 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.

Inosine safety at a glance

Inosine overall Use caution Inosine raises uric acid, which may be a problem for people with gout or kidney issues.
Pregnancy Avoid There is not enough safety information, so it is best avoided during pregnancy.
Breastfeeding Avoid Safety while breastfeeding is unknown, so avoid use.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Misoprostol

Interactions in our licensed database are recorded against drug classes, not just single drug names. Misoprostol is filed under a single classification — oral drugs. Inosine has documented interactions with 1 drug class — the most serious being antigout drugs (moderate) — and none of Misoprostol’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.

Keep it in perspective

What to actually watch for

No Interaction Found — But Data Suggests Inosine and Misoprostol 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. One of them is worth acting on rather than waiting out — marked below.

Reported for Inosine but not commonly for Misoprostol: kidney stones.

Effects for Misoprostol come from the ADVERSE REACTIONS section of its FDA label; effects for Inosine come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 16,478 voluntary FDA FAERS reports for Misoprostol 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.

How to take them

Some Misoprostol Products Have a Food Rule — Inosine Should Not Break It

At least one FDA label for a product containing Misoprostol says to take it with food. If you take Inosine on an empty stomach out of habit, keep them separate — and take Misoprostol with a meal where the label says to.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Misoprostol products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.

DOSAGE AND ADMINISTRATION The recommended adult oral dose of Cytotec for reducing the risk of NSAID-induced gastric ulcers is 200 mcg four times daily with food.

From the Dosage and Administration section of the FDA label we read for Misoprostol — where that label names a specific product, the instruction is that product's. Read the label on DailyMed ›

A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.

See Every Supplement That Interacts With Misoprostol

This page covers Inosine only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Misoprostol page lists 17 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Coffee Charcoal (moderate), European Mandrake (moderate), Glucomannan (moderate) and Guar Gum (moderate).

By severity: 1 major · 7 moderate · 9 minor.

From our pharmacist’s overview on the Misoprostol page

“Misoprostol (Cytotec) is taken by mouth to protect the stomach lining from ulcers caused by NSAID pain relievers, and all 17 of its recorded supplement interactions come down to the same problem, something in the gut keeping the pill from being absorbed properly. That deserves genuine wariness, because misoprostol that never reaches th…”

About Inosine

What is Inosine?

  • Athletic performance and energy
  • Multiple sclerosis (raising uric acid)
  • Parkinson's disease (raising uric acid)
  • General health and recovery

Inosine is a nucleoside (a building block of DNA and RNA) that the body makes on its own and is also sold as a supplement, mostly marketed for athletic performance. Solid evidence that it boosts exercise performance is lacking, and because it raises uric acid levels, it may pose risks for people with gout or kidney problems. Talk with your pharmacist or doctor before using it.

Not applicable; inosine is a naturally occurring compound (a nucleoside), not a plant part · Capsules, tablets, powder

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

Inosine: dosing

There is no well-established, standardized dose of inosine. Amounts used in studies have varied, and there is no proven safe or effective dose for general use.If you choose to use an inosine product, follow the directions on the label and do not exceed the recommended amount. Do not assume that taking more will give better results.

About Misoprostol

What Is Misoprostol Used For?

Brand name: Cytotec

Cytotec (misoprostol) tablets and misoprostol tablets are approved to reduce the risk of gastric ulcers (stomach ulcers) in patients who take NSAIDs — nonsteroidal anti-inflammatory drugs such as aspirin, ibuprofen, or diclofenac — and who are at high risk of ulcer complications. High-risk patients include older adults, people with serious ongoing illnesses, and those with a history of stomach ulcers.

It is important to note that misoprostol has not been shown to reduce the risk of duodenal ulcers (ulcers in the first part of the small intestine) in people taking NSAIDs. It also does not relieve the stomach pain or discomfort that NSAIDs can cause.

Most-Reported Side Effects for Misoprostol

From FAERS, the FDA’s public side-effect reporting system (16,478 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Hemorrhage 1,322 reports
Abortion incomplete 1,159 reports
Nausea 1,031 reports
Arthralgia 977 reports

Taking Inosine and Misoprostol Together: Common Questions

Is it safe to take Inosine with Misoprostol?
We do not list a known interaction between Inosine and Misoprostol. 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 Inosine and Misoprostol have any of the same side effects?
Yes — our sources link each of them separately to 2 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.
Should I take Inosine and Misoprostol at the same time of day?
At least one FDA label for a product containing Misoprostol says to take it with food. If you take Inosine on an empty stomach out of habit, keep them separate and take Misoprostol with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Misoprostol products can differ — so check the directions on your own box. This is about absorption, not an interaction.
How was the Inosine and Misoprostol combination checked?
Interactions in our licensed database are recorded against drug classes. Misoprostol is filed under 1 classification, and Inosine has documented interactions with 1 drug class — none of Misoprostol'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 Inosine interact with any other medications?
Yes. Inosine has 9 documented drug interactions in our database — Misoprostol 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 Misoprostol interact with any supplements?
Yes. Misoprostol has documented interactions with 17 supplements in our database — Inosine is not one of them. The Misoprostol interaction page linked on this page lists every one, ranked by severity.
