Hyaluronic Acid + Granisetron
Granisetron brand names: Kytril, Sustol.
We found no known interaction between Hyaluronic Acid and Granisetron 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 Granisetron states a food rule worth keeping to.
Hyaluronic Acid and Granisetron
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 Granisetron and Hyaluronic Acid 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.
Worth understanding: our licensed dataset holds no drug-interaction record for Hyaluronic Acid at all — not against Granisetron, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.
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.
Hyaluronic Acid safety at a glance
Safety guidance is general; always confirm with your pharmacist or doctor for your situation.
Some Granisetron Products Have a Food Rule — Hyaluronic Acid Should Not Break It
At least one FDA label for a product containing Granisetron says to take it on an empty stomach. Most supplements — Hyaluronic Acid included — are taken with a meal, so the easy mistake is swallowing both together at breakfast. Where that rule applies, keep Granisetron on its own and move Hyaluronic Acid 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 Granisetron 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.
Recommended Dosage ( 2.2 ): The recommended dosage in adults is 10 mg administered as a single subcutaneous injection at least 30 minutes before the start of emetogenic chemotherapy on Day 1.
From the Dosage and Administration section of the FDA label we read for Granisetron — where that label names a specific product, the instruction is that product's. See the Granisetron drug page ›
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.

From our pharmacist’s overview on the Granisetron page
“Granisetron (Kytril, Sustol) blocks serotonin signals to stop nausea from chemotherapy and surgery, and this is a list that warrants real caution before you add a supplement to it. Most of the entries raise serotonin themselves, and stacking them on a serotonin-acting drug can push toward serotonin syndrome, a dangerous overload of tha…”

About Hyaluronic Acid
What is Hyaluronic Acid?
- Skin hydration and aging
- Joint comfort and osteoarthritis
- Dry eyes
- Wound and tissue healing
- Gum and mouth health
Hyaluronic acid is a natural substance in the body that helps hold water in the skin, joints, and eyes. Oral and topical products are popular for skin moisture and joint comfort, and the evidence is moderate for some uses (like dry eyes and skin hydration) but weaker for others. It is generally well tolerated, but talk to your pharmacist or doctor before starting, especially if you are pregnant or breastfeeding.
Naturally found in skin, joints, and connective tissue; supplements are usually made by bacterial fermentation or from animal sources · Oral capsules, tablets, liquids, topical creams and serums, eye drops, and injectable products (given by professionals)
An interaction check asks whether these two react with each other — it does not ask whether Hyaluronic Acid is a good idea for someone in your situation. Here is what our Hyaluronic Acid record says about it on its own.
Hyaluronic Acid: dosing
There is no single standardized dose of hyaluronic acid that fits everyone, and the right amount depends on the form and how it is used.Oral supplements come in a range of strengths, and topical products and eye drops vary by brand.

About Granisetron
What Is Granisetron Used For?
Brand names: Kytril, Sustol
Granisetron is used to prevent nausea and vomiting linked to emetogenic (nausea-causing) cancer chemotherapy — including high-dose cisplatin — and radiation therapy, including total body irradiation and fractionated abdominal radiation. Granisetron hydrochloride tablets and Granisol oral solution are approved for both the chemotherapy and radiation indications. Sancuso skin patch is approved for prevention of nausea and vomiting in adults receiving moderately and/or highly emetogenic chemotherapy regimens of up to 5 consecutive days.
Granisetron hydrochloride injection (intravenous) is also used to prevent and treat postoperative nausea and vomiting in adults. Sustol (subcutaneous injection) is used in combination with other anti-nausea medicines in adults specifically for the prevention of acute and delayed nausea and vomiting associated with moderately emetogenic chemotherapy or anthracycline and cyclophosphamide combination chemotherapy regimens.
