Drug & supplement interaction

Hibiscus Sabdariffa + 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 Hibiscus Sabdariffa 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

Hibiscus Sabdariffa 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 Hibiscus Sabdariffa 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.

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. Hibiscus Sabdariffa has documented interactions with 16 drug classes — the most serious being chloroquine (aralen) (major), antidiabetes drugs (moderate) and antihypertensive drugs (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.

Keep it in perspective

What to actually watch for

No Interaction Found — But Data Suggests Hibiscus Sabdariffa 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.

  • Bloating or gas / Constipation / Stomach pain / Nausea Additional detail

    Hibiscus Sabdariffa

    “Orally, taking a specific Hibiscus sabdariffa leaf extract (Green Chem) 1 gram daily has been associated with reports of transient gastrointestinal symptoms such as abdominal distention, flatulence, and epigastric pain in one clinical trial. However, the overall rate of these adverse effects was similar to placebo.”

Special populations

Hibiscus Sabdariffa in Pregnancy & Breastfeeding

Pregnancy Possibly Unsafe

When used orally. Hibiscus sabdariffa is thought to be a menstrual stimulant, and might have abortifacient effects.

Lactation Possibly Unsafe

When used orally in large amounts. Animal research found that administering large doses of Hibiscus sabdariffa during lactation decreases food and water intake during pregnancy and delays puberty in offspring; however, this has not been assessed in humans.

How to take them

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

At least one FDA label for a product containing Colestipol says to take it on an empty stomach. Most supplements — Hibiscus Sabdariffa 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 Hibiscus Sabdariffa 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 Hibiscus Sabdariffa 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 Hibiscus Sabdariffa

What is Hibiscus Sabdariffa?

Hibiscus Sabdariffa
  • High blood pressure
  • Heart and cholesterol health
  • Digestive upset
  • Antioxidant support
  • Fever and general wellness

Hibiscus sabdariffa is a tart, cranberry-flavored plant most often consumed as a tea, and its best-studied use is for mildly lowering blood pressure. Evidence for other uses is limited, and while hibiscus tea is generally well tolerated in food amounts, concentrated supplements should be used cautiously and avoided in pregnancy. Talk to your pharmacist or doctor before using it for a medical condition.

Hibiscus sabdariffa · Malvaceae · Dried flowers (calyces), and sometimes leaves · Tea, dried calyces, capsules, extracts, juices/beverages

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

Hibiscus Sabdariffa: dosing

There is no official standardized dose for hibiscus. In studies, people have used it as a tea made from dried calyces or as standardized extracts, but the amounts vary widely between products and studies.If you use a supplement, follow the directions on the product label.

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 Hibiscus Sabdariffa and Colestipol Together: Common Questions

Is it safe to take Hibiscus Sabdariffa with Colestipol?
We do not list a known interaction between Hibiscus Sabdariffa 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 Hibiscus Sabdariffa and Colestipol have any of the same side effects?
Yes — our sources link each of them separately to 5 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 Hibiscus Sabdariffa 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 Hibiscus Sabdariffa 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 Hibiscus Sabdariffa and Colestipol combination checked?
Interactions in our licensed database are recorded against drug classes. Colestipol is filed under 2 classifications, and Hibiscus Sabdariffa has documented interactions with 16 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 Hibiscus Sabdariffa interact with any other medications?
Yes. Hibiscus Sabdariffa has 1,087 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 — Hibiscus Sabdariffa is not one of them. The Colestipol interaction page linked on this page lists every one, ranked by severity.
