Drug & supplement interaction

Rye Grass + Octreotide

Octreotide brand names: Sandostatin, Mycapssa.

No Known Interaction
The bottom line No known interaction

We found no known interaction between Rye Grass and Octreotide 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 Octreotide 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.

Rye Grass and Octreotide

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 Octreotide and Rye Grass 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 Rye Grass at all — not against Octreotide, 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.

No Interaction Found — But Data Suggests Rye Grass and Octreotide May Share a Side Effect

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.

How to take them

Some Octreotide Products Have a Food Rule — Rye Grass Should Not Break It

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

2 DOSAGE AND ADMINISTRATION Take MYCAPSSA orally with a glass of water on an empty stomach, at least 1 hour before a meal or at least 2 hours after a meal (‎ 2.1 ).

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

From our pharmacist’s overview on the Octreotide page

“Take this page with genuine care if you use octreotide (Sandostatin injections or Mycapssa capsules) for acromegaly or hormone-secreting tumors, since steady drug levels are what keep symptoms suppressed. Of the 30 ingredients on file, one rates major, activated charcoal, which can pull octreotide out of circulation and blunt its effec…”

About Rye Grass

What is Rye Grass?

  • Prostate symptoms (BPH)
  • Chronic prostatitis
  • Urinary symptoms
  • General wellness/nutrition
  • Allergy desensitization (research only)

Rye grass pollen extract is most often used as a supplement for prostate-related urinary symptoms, where some small studies suggest a possible benefit, but the overall evidence is limited and not conclusive. It is generally well tolerated, but it is not a proven treatment, and you should talk to your doctor or pharmacist before using it, especially if you have prostate or urinary problems.

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

About Octreotide

What Is Octreotide Used For?

Brand names: Sandostatin, Mycapssa

Octreotide injection (available as Sandostatin, BYNFEZIA Pen, and other octreotide acetate injection products) is used to lower abnormally high growth hormone and IGF-1 levels in acromegaly, and to reduce the severe diarrhea and flushing associated with metastatic carcinoid tumors and the profuse watery diarrhea caused by VIPomas (vasoactive intestinal peptide-secreting tumors).

Mycapssa, the oral delayed-release capsule, is approved specifically for long-term maintenance treatment of acromegaly in patients who have already responded to and tolerated treatment with octreotide or lanreotide injections. It is not indicated for carcinoid tumors or VIPomas.

Taking Rye Grass and Octreotide Together: Common Questions

Is it safe to take Rye Grass with Octreotide?
We do not list a known interaction between Rye Grass and Octreotide. 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 Rye Grass and Octreotide have any of the same side effects?
Yes — our sources link each of them separately to one 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 Rye Grass and Octreotide at the same time of day?
At least one FDA label for a product containing Octreotide 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 Octreotide on its own and move Rye Grass 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.
Does Octreotide interact with any supplements?
Yes. Octreotide has documented interactions with 30 supplements in our database — Rye Grass is not one of them. The Octreotide interaction page linked on this page lists every one, ranked by severity.
