SOMATOSTATIN

Background and Date of Approval

Somatostatin received FDA approval on June 26, 2020 for the treatment of acromegaly.

Uses

It is used to reduce the amount of growth hormone produced by people with acromegaly (a condition in which the body produces too much growth hormone, causing enlargement of the hands, feet, and facial features; joint pain; and other symptoms) who cannot be treated with surgery, radiation, or another medication. It is also used to control diarrhea and flushing caused by carcinoid tumors (slow-growing tumors that release natural substances that can cause symptoms) and vasoactive intestinal peptide-secreting adenomas (VIP-omas; tumors that form in the pancreas and release natural substances that can cause symptoms). It is used to prevent complications following surgery of the pancreas gland. It is also indicated to stop bleeding and to protect from re-bleeding from ruptured gastro-esophageal varices in patients suffering from chronic liver disease. This medicine is used to treat people with pituitary tumors that produce too much thyroid-stimulating hormone (TSH) when other types of treatment (surgery or radiotherapy) are not suitable or have not worked and after radiotherapy, to cover the interim period until the radiotherapy becomes fully effective.

How is it administered?

Somatostatin is available as an immediate-release solution (liquid) for injection in the doses of 10 mg, 20 mg, and 30 mg. It is intended for administration via the subcutaneous or intravenous route. It must be administered only under the supervision of a healthcare professional at around the same time every day. Check for discoloration and the presence of particles before injecting.

Side Effects

The side effects known to occur commonly during the treatment with Somatostatin are nausea, vomiting, bloating, diarrhea, abdominal pain, constipation, flatulence, hair loss, etc. This medicine could also alter your blood glucose, thyroid, and liver enzyme levels. Report to your doctor immediately if you experience difficulty breathing, rapid heartbeat, gall bladder abnormalities, blood glucose fluctuations, or hypothyroidism.

Warnings

Contact your physician immediately if you experience allergies to Somatostatin and its ingredients. During the Somatostatin injection treatment, your doctor may periodically monitor your blood sugar level, thyroid function, and liver or pancreatic enzyme function to prevent serious complications. Report to your doctor if you have an irregular heartbeat, gallstones, problems with blood sugar levels, either too high (hyperglycemia) or too low (hypoglycemia), or issues with the liver or kidneys. Discuss with your doctor if you have a medical history of vitamin B12 deficiency.

Precautions

If you are pregnant or planning to have a baby, consult a doctor before taking this medicine. Your healthcare provider will prescribe Somatostatin only if it is necessary for you. Avoid breastfeeding your baby while on the treatment as it is unknown if Somatostatin passes into the breastmilk.

Word of Advice

Allow somatostatin to reach room temperature before administration if it has been stored in the refrigerator. This reduces the risk of pain at the injection site. Do not heat the medication; you may warm it gently in your palm. If pain occurs at the subcutaneous injection site, gentle rubbing of the area may provide relief.
