trade name for octreotide. Sandostatin LAR and octreotide acetate are other names
for octreotide. In some cases, health care professionals may use the trade name
sandostatin or other names sandostatin LAR or octreotide acetate when referring

Drug type: Octreotide is hormone drug that is used to treat
some types of cancer. This medication is classified as an somatostatin analog.
(For more detail, see "How this drug works" section below).
What Octreotide Is Used For:
- This medicine is given to control symptoms such as diarrhea or flushing in patients
with tumors such as carcinoid, pancreatic islet cell tumors, gastrinoma, or vasoactive
intestinal peptide-secreting tumors (VIPomas).
- It is also used to treat acromegaly, when the body produces too much growth hormone,
and the hands, feet, face or head grow too large.
Note: If a drug has been approved for one use, physicians
may elect to use this same drug for other problems if they believe it may be helpful.
How Octreotide Is Given:
- Octreotide has two formulations. For purposes of clarity, trade names will
be used for discussion. Sandostatin®is a short
acting version and Sandostatin LAR®is a long acting
- Sandostatin® is given by subcutaneous injection
(S.C. - the layer of tissue between the skin and the muscle). It may be necessary
to take the shot several times a day. The injection sites should be rotated
regularly. This medication may also be given intravenously.
- Sandostatin LAR® is given by intramuscular injection
(IM - into the muscle) under a doctor's supervision. This medication is generally
given once every 4 weeks. The preferred site for injection is the hip, because
it is painful given into the arm. Sandostatin LAR®
should NOT be given by S.C. or IV routes.
- If short acting Sandostatin® is to be replaced
by long-acting Sandostatin LAR®, short acting Sandostatin® should be continued for at least two weeks to maintain
therapeutic doses in patients with carcinoid tumors or VIPomas.
- Short acting Sandostatin® may also be used to control
breakthrough syptoms in carcinoid.
- The amount of octreotide that you will receive depends on many factors, including
your height and weight, your general health or other health problems, and the type
of cancer or condition being treated. Your doctor will determine your dose
Important things to remember about the side effects of octreotide:
- Most people do not experience all of the side effects listed.
- Side effects are often predictable in terms of their onset and duration.
- Side effects are almost always reversible and will go away after treatment is complete.
- There are many options to help minimize or prevent side effects.
- There is no relationship between the presence or severity of side effects and the
effectiveness of the medication.
- The side effects of octreotide and their severity depend on how much of the drug
is given and which preparation (Sandostatin® or
Sandostatin LAR®) is given. In other words,
high doses may produce more severe side effects.
The following side effects are common (occurring in greater than 30%) for
patients taking Octreotide:
- Gallstones (common with long term use but rarely symptomatic enough to require intervention).
- Pain at the injection site (especially with Sandostatin LAR®)
These side effects are less common side effects (occurring in about 10-29%)
of patients receiving octreotide:
- Abdominal Pain
- Flatulence (gas)
- Diarrhea (may be due to the disease rather than the medication)
- Upper respiratory infection (see lung problems)
- Flu-like syndrome
- If you have diabetes, your blood sugar levels may be affected. Discuss this with
your healthcare provider, how you will monitor your blood sugar readings at home.
- You may experience a slower heartbeat

to octreotide. Keep all appointments for tests, and office visits.
- Your doctor may also monitor other types of blood work, to see if the medication
is affecting other parts of your body.
How Octreotide Works:
Octreotide is similar to a natural chemical called somatostatin. Somatostatin
is produced in the body by the hypothalamus. One of its functions is to "switch
off" the secretion of growth hormone by the pituitary gland. Somatostatin
also decreases splanchnic blood flow and inhibits the release of serotonin, gastrin,
vasoactive intestinal peptide, secretin, motilin and pancreatic polypeptide.
These actions are what helps to control the symptoms of flushing and diarrhea in
carcinoid tumors and Vasoactive Intestinal Peptide (VIP) secreting adenomas.
Somatostatin is chemically unstable and broken down by the body within minutes of
its release. Octreotide, in contrast, is very stable and, therefore, much
longer acting. It is for this reason that octreotide is preferred for medicinal
