The bottom line No known interaction

We found no known interaction between Hesperidin and Guaifenesin 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.

Interaction report

Hesperidin and Guaifenesin

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 Guaifenesin and Hesperidin 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 Guaifenesin

Interactions in our licensed database are recorded against drug classes, not just single drug names. Guaifenesin is filed under 2 classifications — including oral drugs. Hesperidin has documented interactions with 7 drug classes — the most serious being anticoagulant/antiplatelet drugs (moderate), antihypertensive drugs (moderate) and celiprolol (celicard) (moderate) — and none of Guaifenesin’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

What Hesperidin Itself Has Been Linked To

This is not an interaction — nothing below involves Guaifenesin. It is the side-effect record for Hesperidin on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Hesperidin, this list is the first place to look.

  • A skin rash Additional detail

    “A case of recurrent allergic dermatitis was reported in a 70-year-old female with no known allergies who applied topical hesperidin methyl chalchone.”

Everything above comes from the Natural Medicines adverse-effect record for Hesperidin — expand a row for the licensed statement it rests on. We haven’t matched Guaifenesin to its FDA label in our system yet, so we can’t compare its own side-effect list here — the leaflet that comes with your prescription is the authoritative list for Guaifenesin.

Special populations

Hesperidin in Pregnancy & Breastfeeding

Pregnancy And Lactation Likely Safe

When used orally in amounts found in foods.

Pregnancy And Lactation Possibly Safe

When used orally in doses of up to 100 mg daily for 30 days in combination with diosmin. Some evidence suggests that taking this combination may be associated with placental insufficiency when used during the third trimester of pregnancy; however, the combination does not seem to induce fetal abnormalities, retard fetal growth, increase the risk of intrauterine death, or affect birth weight. Also, when breastfeeding, this combination does not seem to affect infant growth or feeding.

This page covers Hesperidin only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Guaifenesin page lists 26 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Grapefruit (major), Berberine (moderate), Bitter Orange (moderate) and Coffee Charcoal (moderate).

By severity: 2 major · 15 moderate · 9 minor.

From our pharmacist’s overview on the Guaifenesin page

“Guaifenesin (Robitussin, Humibid LA) loosens chest mucus, and by itself it is a mild medicine, but two of the 26 supplements on this list rate major, so those two deserve your attention first. Activated charcoal can bind the drug in your gut and blunt what it does, and grapefruit raises blood levels of dextromethorphan, the cough suppr…”

About Hesperidin

What is Hesperidin?

Hesperidin
  • Hemorrhoids
  • Varicose veins and poor circulation
  • Leg swelling (venous insufficiency)
  • High blood pressure
  • Antioxidant support

Hesperidin is a flavonoid found in citrus fruits that is often combined with diosmin and used for vein and circulation problems like hemorrhoids and varicose veins. Some evidence supports these uses, but data for many other claims is limited. It is generally well tolerated, but pregnant and breastfeeding people should avoid it because safety has not been established.

Rutaceae · Fruit and peel of citrus fruits (especially oranges and lemons) · Capsules, tablets, often combined with diosmin or vitamin C as a bioflavonoid complex

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

Hesperidin: dosing

There is no official standardized dose of hesperidin. The amount used in research varies depending on the product and whether it is combined with diosmin or other ingredients.The best approach is to follow the directions on the product label and not exceed the recommended amount.

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

About Guaifenesin

What Is Guaifenesin Used For?

Brand names: Robitussin, Humibid LA, Amibid LA, Numobid, Muco-Fen 800, Bidex, Organidin, X-pect, Mucinex

Guaifenesin helps loosen phlegm (mucus) and thin bronchial secretions — the sticky fluid in your airways — so your cough can clear it out more effectively. It is used to relieve chest congestion associated with colds, respiratory infections, and other conditions that cause a mucus-filled cough.

This use is supported across multiple products including tablets, extended-release tablets, and oral solutions such as Childrens Mucus Relief, Tussin, Guaifenesin STRAWBERRY-BANANA FLAVOR, 12 Hour Mucus Relief, 365 Whole Foods Market Guaifenesin, Dr. Simi Mucus Relief, and others.
