Drug & supplement interaction

Tyramine + Colestipol

Colestipol brand name: Colestid.

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 Tyramine and Colestipol 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 Colestipol 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.

Interaction report

Tyramine and Colestipol

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 Colestipol and Tyramine 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.

Tyramine safety at a glance

Tyramine overall Use caution Tyramine in normal foods is fine for most people, but it can be harmful for those who are sensitive or taking certain drugs.
Pregnancy Use caution Tyramine from ordinary food is generally fine, but concentrated supplemental use is not recommended and not well studied.
Breastfeeding Use caution Tyramine from a normal diet is generally fine, but deliberately taking it in supplement form is not advised due to a lack of safety data.

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

How we checked

Why No Interaction Is Listed for Colestipol

Interactions in our licensed database are recorded against drug classes, not just single drug names. Colestipol is filed under 2 classifications — bile acid sequestrants, oral drugs. Tyramine has documented interactions with 4 drug classes — the most serious being antihypertensive drugs (major), monoamine oxidase inhibitors (maois) (major) and alcohol (moderate) — and none of Colestipol’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 Tyramine and Colestipol 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.

  • Chest pain Worth acting on Additional detail

    Tyramine

    “Orally and intravenously, unspecified doses of tyramine have increased systolic, but not diastolic, blood pressure. Intravenous tyramine is not used clinically but is commonly used to examine safety and interaction outcomes. A single dose of oral tyramine 400 mg has been reported to cause heart palpitations and elevations in systolic blood pressure in healthy volunteers.”

How to take them

Some Colestipol Products Have a Food Rule — Tyramine Should Not Break It

At least one FDA label for a product containing Colestipol says to take it on an empty stomach. Most supplements — Tyramine included — are taken with a meal, so the easy mistake is swallowing both together at breakfast. Where that rule applies, keep Colestipol on its own and move Tyramine to a meal later in the day.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Colestipol 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.

Patients should take other drugs at least one hour before or four hours after colestipol hydrochloride tablets to minimize possible interference with their absorption.

From the Dosage and Administration section of the FDA label we read for Colestipol — 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.

Everything else you take

See Every Supplement That Interacts With Colestipol

This page covers Tyramine only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Colestipol page lists 18 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 · 8 moderate · 9 minor.

From our pharmacist’s overview on the Colestipol page

“Take colestipol (Colestid), a cholesterol drug that works by trapping bile acids in your gut, and nearly every one of the 18 supplement interactions on file comes down to absorption. Only one rates major, activated charcoal, and it belongs at the top of your reading.”

About Tyramine

What is Tyramine?

  • Studied for effects on blood pressure
  • Discussed in relation to migraine and headache triggers
  • Of interest in food and diet science
  • Subject of research on the nervous system

Tyramine is a natural compound formed when certain proteins break down, and it is found in aged cheeses, cured meats, fermented foods, and some other items. It is not a typical health supplement and is best known for the problems it can cause—such as dangerous spikes in blood pressure—in people taking certain medications or in those who are sensitive to it. If you have been told to follow a low-tyramine diet, talk with your pharmacist or doctor before making changes.

Not a plant part; tyramine is a naturally occurring compound found in many foods · Naturally present in aged and fermented foods; not commonly sold as a stand-alone supplement

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

Tyramine: dosing

There is no recommended supplement dose for tyramine, because it is not meant to be taken as a health product. Instead, the main guidance is about how much tyramine to allow in the diet for people who are sensitive to it.If you have been placed on a low-tyramine diet, the goal is usually to limit aged, fermented, cured, or spoiled foods rather than to count exact milligrams. Your pharmacist or doctor can give you a food list suited to your situation.Do not try to take tyramine on purpose.

About Colestipol

What Is Colestipol Used For?

Brand name: Colestid

Colestipol — available as oral suspension and tablets under brands including Colestid, Flavored Colestid, and Colestipol Hydrochloride — is used as part of a broader treatment plan (including diet) to lower elevated LDL cholesterol in adults with primary hypercholesterolemia (a condition where LDL cholesterol stays high despite dietary changes).

It is not a standalone fix. Diet, weight management, and other lifestyle changes come first, and colestipol is added when those steps alone aren't enough to reach target LDL levels.

Taking Tyramine and Colestipol Together: Common Questions

Is it safe to take Tyramine with Colestipol?
We do not list a known interaction between Tyramine and Colestipol. 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 Tyramine and Colestipol 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.
Should I take Tyramine and Colestipol at the same time of day?
At least one FDA label for a product containing Colestipol says to take it on an empty stomach, and supplements are usually taken with a meal — so taking them together at breakfast is the easy mistake. Where that applies, keep Colestipol on its own and move Tyramine to a meal later in the day. Food instructions belong to the product rather than the ingredient, so check the directions on your own box. This is about absorption, not an interaction.
How was the Tyramine and Colestipol combination checked?
Interactions in our licensed database are recorded against drug classes. Colestipol is filed under 2 classifications, and Tyramine has documented interactions with 4 drug classes — none of Colestipol'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 Tyramine interact with any other medications?
Yes. Tyramine has 353 documented drug interactions in our database — Colestipol 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 Colestipol interact with any supplements?
Yes. Colestipol has documented interactions with 18 supplements in our database — Tyramine is not one of them. The Colestipol interaction page linked on this page lists every one, ranked by severity.
