As of September 2026, octreotide has been approved in the US since 1988 for acromegaly and for symptoms of carcinoid and other neuroendocrine tumors. The EMA approved it for equivalent uses. Its many off-label uses have less controlled human data than its labeled ones. None of that tells you what is inside a vial that reached you outside a pharmacy.

What is octreotide?
Octreotide is a lab-made, shortened version of the natural hormone somatostatin. Sandoz chemists led by Wilfried Bauer engineered it in the late 1970s and early 1980s to last much longer in the body. The FDA approved it in 1988, at first for acromegaly and for diarrhea and flushing from carcinoid and other neuroendocrine tumors.
Does octreotide work?
For acromegaly and for symptoms of carcinoid and other neuroendocrine tumors, the FDA reviewed the trials and approved it. The record says the EMA's approval covers equivalent uses.
What we found. 10+ completed randomized trials counted on the record. 3 study rows listed below, and each stands for a group of trials. The number shows with a plus sign until every trial is listed.
| Study | Tested in | Status | What it shows |
|---|---|---|---|
| Original acromegaly registration trials (Phase 2 and 3) | People | Completed. Approved in 1988 | Octreotide lowered growth hormone and IGF-1 in people with acromegaly |
| Carcinoid syndrome trials | People | Completed. Approval followed | Fewer episodes of flushing and diarrhea in carcinoid syndrome |
| Trials of the long-acting version, Sandostatin LAR | People | Completed. Approval followed | In comparative trials it kept hormone control similar to the short-acting version |
Is octreotide safe?
The record points to decades of clinical use. The main concerns it names include gallstones, blood sugar changes and effects where the medicine is given, with long-term use. Most trials looked at conditions of hormone excess. For its many off-label uses, less controlled human data exist than for its labeled ones. So far this is about Sandostatin from a pharmacy. The vial section deals with anything sold under the name elsewhere.
Is octreotide legal?
- United States
- Approved by the FDA since 1988 as Sandostatin, for acromegaly and for symptoms of carcinoid and other neuroendocrine tumors.
- European Union
- Approved by the EMA.
- Sport
- Not named on WADA's list. That is not clearance.
- Other uses
- Used off-label, meaning outside the approved label, for severe diarrhea and some bleeding in the gut. The record says these uses have less controlled human data.

What is in a vial sold as octreotide?
The trials above stand behind Sandostatin and its long-acting version, Sandostatin LAR. This record gives no sign that octreotide is sold outside pharmacies. A vial that reached you some other way was not what those trials tested, and the checklist lists what to ask the seller.
What don't we know?
- What controlled trials would show for its many off-label uses. Those uses have less controlled human data.
- Whether newer somatostatin analogues or receptor-targeted medicines do better in specific off-label uses.
- What is in any vial of octreotide that came from outside a pharmacy.
The other side
A prescription and a doctor's care come with octreotide, and the record counts decades of clinical use since its 1988 approval. Its thinner side is the off-label uses, where controlled human data are fewer than for the labeled ones.
What would change this record?
- Head-to-head trials against newer somatostatin analogues or receptor-targeted medicines in specific off-label uses. They would clarify how the benefit compares.
Three questions to ask next
- What does 'research use only' actually mean?
- How can you tell if a peptide vendor is legitimate?
- How do you read a certificate of analysis?
Ask better questions.
More questions about octreotide
What is octreotide used for?
- Acromegaly, and symptoms of carcinoid and other neuroendocrine tumors such as diarrhea and flushing. Those are the uses the FDA approved.
Is octreotide the same as Sandostatin?
- Sandostatin is the brand name for octreotide. Sandostatin LAR is its long-acting version.
What does octreotide do in the body?
- It holds back the release of growth hormone and several digestive hormones, the record says.
Is octreotide used off-label?
- Yes. The record names severe diarrhea and some bleeding in the gut. It says those uses have less controlled human data than the labeled ones.
Is octreotide banned in sport?
- It is not named on WADA's list. The record gives no sport source for that. If you compete, check the current List.
