The bottom line No known interaction

We found no known interaction between Gras and Exenatide 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.

Gras and Exenatide

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 Exenatide and Gras 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 Gras at all — not against Exenatide, 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.

Gras safety at a glance

Gras overall Not established We cannot confirm what "Gras" is, so its safety is unknown.
Pregnancy Avoid Because the product is unidentified, avoid it during pregnancy unless a doctor confirms it is safe.
Breastfeeding Avoid With no reliable information, avoid it while breastfeeding unless cleared by your doctor.

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

What to actually watch for

What Exenatide’s Own FDA Label Lists

This is not an interaction — none of it involves Gras. These are the most notable effects listed in the ADVERSE REACTIONS section of Exenatide’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 10 of them are worth acting on rather than waiting out — marked below.

  • Low blood sugar Worth acting on mentioned in 10.5% of FDA reports for Exenatide
  • A bowel blockage Worth acting on
  • Dehydration Worth acting on
  • Pancreatitis Worth acting on
  • Chest pain Worth acting on
  • A low platelet count Worth acting on
  • Kidney problems Worth acting on
  • A severe allergic reaction Worth acting on
  • Hives Worth acting on
  • Bleeding or bruising Worth acting on

Showing the 10 most notable of 31 label-listed effects — ranked by how unusual each one is across medicines generally, with serious effects weighted up.

From the ADVERSE REACTIONS section of the FDA label for Exenatide. Read the label on DailyMed › Where a percentage is shown, it is the share of 52,314 voluntary FDA FAERS reports for Exenatide that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Gras’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Gras side to compare — that is a limit of the record, not a statement that Gras has no side effects.

From our pharmacist’s overview on the Exenatide page

“Because exenatide (Byetta, Bydureon) exists to lower blood sugar, nearly every supplement on this list pulls at that same lever, and I treat that as a genuine warning rather than a footnote. Most entries, including everyday items like fenugreek, bitter melon, flaxseed, and ginseng, can drop glucose further and raise the odds of hypogly…”

Where does our data come from?
  • Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Gras is not yet covered by that licensed database, so its write-up cites publicly available medical sources directly (see the references below).
  • Citation library: 103,510 references behind our interaction content, 65,311 of them resolved to verified PubMed/DOI sources. See every Gras reference on this page ↓
  • Freshness: we automatically re-check this combination every week — this pair was last verified September 20, 2026. The Gras and Exenatide records this page draws on were last updated June 20, 2026.
  • What “no known interaction” means: no documented interaction in the sources above — not a guarantee of safety. Supplements are studied far less than prescription drugs, so we say exactly what the evidence supports, and nothing more.

About Gras

What is Gras?

We could not find reliable information about a dietary supplement or herb called "Gras." The name may be a misspelling, a brand name, or a local/regional term, so we cannot confirm what it is, what it does, or whether it is safe. Please double-check the name with your pharmacist or the product label before using it.

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

Gras: dosing

There is no established or recommended dose for "Gras" because the product cannot be reliably identified. We will not guess an amount. If you have a labeled product, follow the manufacturer's instructions only after confirming the actual ingredient with a pharmacist or doctor.

About Exenatide Injection

What Is Exenatide Injection Used For?

Brand names: Byetta, Bydureon

Exenatide injection is used as an addition to diet and exercise to improve blood sugar control in adults with type 2 diabetes. It is not a substitute for healthy lifestyle changes — it works best when combined with them.

It should not be used together with other exenatide-containing products. The brands Byetta, Bydureon, and BYDUREON BCise all contain exenatide and should never be combined with each other.

Most-Reported Side Effects for Exenatide

From FAERS, the FDA’s public side-effect reporting system (52,314 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Blood glucose increased 15,475 reports
Weight decreased 12,125 reports
Nausea 12,042 reports
Decreased appetite 5,643 reports
Blood glucose decreased 5,517 reports
