What is Octreotide: Uses, Dosage, Side Effects and More

Octreotide is a synthetic hormone medication that mimics a natural hormone called somatostatin in your body. Think of it as a specialized messenger that helps control the release of certain hormones and substances that can cause uncomfortable symptoms. This medication is particularly helpful for people dealing with specific hormone-related conditions or certain types of tumors that produce excess hormones.

What is Octreotide?

Octreotide is a man-made version of somatostatin, a hormone your body naturally produces to regulate other hormones. Your pancreas and intestines normally make somatostatin to keep various body functions in balance. When you take octreotide, it steps in to do this job more effectively than your body might be managing on its own.

This medication belongs to a class of drugs called somatostatin analogs. The word "analog" simply means it's designed to work like the real thing but often lasts longer and works more predictably. Octreotide helps slow down the overproduction of certain hormones and digestive substances that can make you feel quite unwell.

What is Octreotide Used For?

Octreotide treats several conditions where your body produces too much of certain hormones or substances. The most common use is for people with carcinoid syndrome, a condition where tumors release excess hormones that cause flushing, diarrhea, and other uncomfortable symptoms.

Your doctor might prescribe octreotide if you have any of these conditions:

• Carcinoid syndrome from neuroendocrine tumors
• VIPomas (tumors that produce too much vasoactive intestinal peptide)
• Severe diarrhea from certain tumors
• Acromegaly when other treatments haven't worked well
• Bleeding from esophageal varices in emergency situations

In rarer cases, doctors sometimes use octreotide for other conditions like certain types of hypoglycemia or to help manage symptoms from pancreatic tumors. Your healthcare provider will determine if this medication is right for your specific situation.

How Does Octreotide Work?

Octreotide works by binding to specific receptors in your body, much like a key fitting into a lock. Once it connects to these receptors, it sends signals that slow down the release of various hormones and substances. This is particularly important when tumors are producing too much of these substances.

The medication is considered moderately strong and very targeted in its action. It doesn't affect your entire hormone system but focuses on specific pathways that are causing problems. This targeted approach helps reduce unwanted symptoms while minimizing effects on other body functions.

Most people start feeling some relief within a few hours to days of starting treatment. The full benefits often develop over several weeks as your body adjusts to the medication and hormone levels stabilize.

How Should I Take Octreotide?

Octreotide comes in different forms, and your doctor will choose the best option for you. The immediate-release form is usually given as an injection under your skin two to four times daily. There's also a long-acting form that's injected into your muscle once a month.

For injections, you'll likely learn to give them to yourself at home. Your healthcare team will teach you the proper technique and rotation of injection sites. Common injection areas include your thigh, upper arm, or abdomen. It's important to rotate where you inject to prevent skin irritation.

You can take octreotide with or without food, though taking it at the same times each day helps maintain steady levels in your body. If you're getting the monthly injection, you'll need to visit your doctor's office or clinic for this procedure.

How Long Should I Take Octreotide For?

The length of treatment with octreotide depends entirely on your specific condition and how well you respond to the medication. Some people need it for just a few months, while others may take it for years or even indefinitely.

If you have carcinoid syndrome or other hormone-producing tumors, you might need long-term treatment to keep symptoms under control. Your doctor will regularly check how well the medication is working and whether you're experiencing any concerning side effects.

For emergency situations like bleeding varices, octreotide is typically used for just a few days. Never stop taking octreotide suddenly without talking to your doctor first, as this could cause your symptoms to return quickly.

What Are the Side Effects of Octreotide?

Like most medications, octreotide can cause side effects, though not everyone experiences them. The good news is that most side effects are manageable and often improve as your body gets used to the medication.

Here are the most common side effects you might experience:

• Nausea and stomach upset
• Diarrhea or loose stools
• Abdominal pain or cramping
• Injection site reactions like redness or swelling
• Headaches
• Dizziness
• Fatigue

These common side effects usually improve within a few weeks as your body adjusts to the medication. However, you should contact your doctor if they become severe or don't improve over time.

Some people may experience more serious but less common side effects that require medical attention:

• Gallbladder problems or gallstones
• Changes in blood sugar levels
• Thyroid function changes
• Heart rhythm irregularities
• Severe abdominal pain
• Yellowing of skin or eyes

Very rarely, some people might develop vitamin B12 deficiency with long-term use, or experience severe allergic reactions. Your doctor will monitor you regularly to catch any potential problems early.

Who Should Not Take Octreotide?

Octreotide isn't suitable for everyone, and your doctor will carefully consider your medical history before prescribing it. You should not take octreotide if you're allergic to it or any of its ingredients.

Your doctor will be especially cautious about prescribing octreotide if you have certain conditions:

• Diabetes or blood sugar problems
• Gallbladder disease or history of gallstones
• Thyroid disorders
• Heart rhythm problems
• Kidney or liver disease
• Vitamin B12 deficiency

If you're pregnant or breastfeeding, your doctor will carefully weigh the benefits and risks. While octreotide isn't known to cause birth defects, it's not routinely recommended during pregnancy unless absolutely necessary.

Octreotide Brand Names

Octreotide is available under several brand names, with Sandostatin being the most well-known. The immediate-release form is called Sandostatin, while the long-acting monthly injection is known as Sandostatin LAR.

Other brand names include Mycapssa, which is an oral capsule form, and various generic versions. Your pharmacy might carry different brands, but they all contain the same active ingredient and work in similar ways.

Octreotide Alternatives

If octreotide isn't right for you or doesn't work well enough, your doctor has other options to consider. Lanreotide is another somatostatin analog that works very similarly to octreotide and might be a good alternative.

For specific conditions, other treatments might include:

• Pasireotide for certain pituitary tumors
• Telotristat for carcinoid syndrome diarrhea
• Diazoxide for certain types of hypoglycemia
• Various targeted cancer therapies depending on your tumor type

Your doctor will consider your specific condition, how well you've responded to other treatments, and your overall health when exploring alternatives.

Is Octreotide Better Than Lanreotide?

Both octreotide and lanreotide are excellent medications that work in very similar ways. Neither is definitively "better" than the other - the choice often comes down to individual factors like how well you respond, side effects you experience, and practical considerations.

Some people find one medication more convenient than the other. For example, lanreotide might be given less frequently, while octreotide offers more dosing flexibility. Your doctor will help you determine which option fits best with your lifestyle and medical needs.

The most important thing is finding the medication that gives you the best symptom control with the fewest side effects. This sometimes requires trying different options to see what works best for your body.
