Somatostatin Dosage

Research-based dosing protocols, timing guidance, and reconstitution reference for Somatostatin. All information is for educational purposes only.

Quick Answer

Native somatostatin has an extremely short half-life (~2 minutes) and is not used clinically. Synthetic somatostatin analogs (octreotide, lanreotide, pasireotide) are used for therapeutic purposes and have specific dosing regimens depending on the indication.

Standard Dosage Range

Research dosing range: Not applicable for native somatostatin. See dosing guidelines for synthetic analogs.

Educational reference only

These dosage ranges are derived from preclinical research and community protocols. No human clinical dose-ranging trials have established therapeutic doses for most research peptides. Always consult a qualified healthcare provider before starting any peptide protocol.

Dosage by Use Case

Acromegaly (Octreotide)

50–500 mcg2–3× daily
Duration

Chronic

Subcutaneous injection. Dosing is highly individualized based on IGF-1 levels and symptom control. Administer between meals and at bedtime to avoid hyperglycemia. Monitor for gallstones and other side effects.

Acromegaly (Lanreotide)

60–120 mgEvery 28 days
Duration

Chronic

Intramuscular injection. Requires deep intragluteal injection performed by healthcare professional. Dosage adjusted based on IGF-1 levels. Monitor for gallstones and glucose dysregulation.

Neuroendocrine Tumors (Octreotide)

100–600 mcg2–3× daily
Duration

Chronic

Subcutaneous injection. Used to control symptoms such as flushing and diarrhea associated with carcinoid syndrome. Dosing is titrated to symptom control. Monitor for B12 deficiency with prolonged use.

Neuroendocrine Tumors (Lanreotide)

120 mgEvery 28 days
Duration

Chronic

Intramuscular injection. Helps control tumor growth and symptoms. Dosage adjustments may be necessary. Monitor for injection site reactions.

Cushing Disease (Pasireotide)

0.6–0.9 mg2× daily
Duration

Chronic

Subcutaneous injection. Used for patients with Cushing disease who are not candidates for surgery or whose tumors have not been fully removed. Monitor for hyperglycemia and adrenal insufficiency.

Variceal Bleeding (Octreotide)

50 mcg IV bolus, then 50 mcg/hour IV infusionContinuous infusion
Duration

2-5 days

Used to reduce portal pressure and control acute esophageal variceal hemorrhage. Often used in conjunction with other therapies, such as endoscopic banding.

Timing & Frequency

Synthetic somatostatin analogs are typically administered subcutaneously or intramuscularly, with the specific timing depending on the medication and indication. Octreotide is generally administered between meals and at bedtime to minimize hyperglycemia. Lanreotide is given via monthly intramuscular injection.

Cycle Guidance

Use of somatostatin analogs is typically chronic and guided by a physician. Dosage adjustments and monitoring are essential to minimize side effects and optimize therapeutic outcomes.

Frequently Asked Questions

What are somatostatin analogs used for?
Somatostatin analogs like octreotide, lanreotide, and pasireotide are used to treat acromegaly, neuroendocrine tumors, Cushing disease, and to control variceal bleeding.
How are somatostatin analogs administered?
They are administered via subcutaneous (octreotide, pasireotide) or intramuscular (lanreotide) injection. The frequency of administration varies depending on the specific analog.
What are the common side effects of somatostatin analogs?
Common side effects include nausea, diarrhea, abdominal pain, gallstones, hyperglycemia, and injection site reactions. Less common but more serious side effects include cardiac arrhythmias and bowel ischemia.
What should I monitor while taking somatostatin analogs?
Regular monitoring of IGF-1 levels (for acromegaly), blood glucose, liver function tests, vitamin B12 levels, and thyroid function is recommended. Gallbladder ultrasound should be performed periodically.
Can I take somatostatin orally?
Native somatostatin cannot be taken orally due to its rapid degradation in the gastrointestinal tract. Oral somatostatin analogs are under development, but none are currently approved.
