Thyroid Extract and Octreotide

Here is the interaction we found between these two, with the evidence behind it.

Minor

Oral Drugs

Why this applies to Octreotide

Octreotide falls under Oral Drugs — the group Thyroid Extract interacts with.

Food and medications can interfere with thyroid hormone absorption. Some foods, particularly those high in fiber or containing certain minerals like calcium or iron, can bind to thyroid hormones and reduce their absorption in the digestive tract. Additionally, taking thyroid medications with certain drugs, like antacids or calcium supplements, can hinder the effectiveness of the thyroid medication, necessitating adjustments in dosage or timing. Prescription thyroid medications, such as Synthroid, are recommended to be taken on an empty stomach, at least 30 minutes before food and other medications, for optimal absorption.
Severity Minor Likelihood Likely Evidence A

Well-controlled human studies have demonstrated the likely existence of this interaction.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the deal with this pairing: octreotide can actually slow down how your gut absorbs other things you swallow, and that includes the thyroid hormone in a thyroid extract supplement. So if you take both around the same time, your body may pick up less of the thyroid hormone than expected. That could leave thyroid symptoms (tiredness, feeling cold, sluggishness) not as well controlled.

The good news is this is rated a minor, manageable interaction, and it's usually about timing, not danger. Separating the two doses often helps. Since over-the-counter thyroid extracts are unpredictable to begin with, please loop in your doctor or pharmacist so your thyroid levels and timing are set up safely.

From our pharmacist’s overview on the Octreotide page

“Take this page with genuine care if you use octreotide (Sandostatin injections or Mycapssa capsules) for acromegaly or hormone-secreting tumors, since steady drug levels are what keep symptoms suppressed.

About Thyroid Extract

What is Thyroid Extract?

Thyroid Extract
  • Hypothyroidism (underactive thyroid)
  • Fatigue and low energy
  • Weight management
  • Sluggish metabolism
  • General thyroid support

Thyroid extract supplements are made from dried animal thyroid gland and may contain real thyroid hormones (T3 and T4), but the amounts in over-the-counter products are not standardized and can be unpredictable. Self-treating a thyroid problem with these supplements can be risky, so always work with a doctor or pharmacist and use prescription thyroid medicine when treatment is needed.

About Octreotide

What Is Octreotide Used For?

Brand names: Sandostatin, Mycapssa

Octreotide treats conditions caused by hormone-producing problems. Injection products are used for acromegaly, severe diarrhea and flushing from metastatic carcinoid tumors, and profuse watery diarrhea from VIP-secreting tumors (VIPomas).

Mycapssa (oral capsule) is used only for long-term maintenance treatment of acromegaly in people who responded to and tolerated octreotide or lanreotide. Long-acting injectable suspension products (such as Sandostatin LAR Depot) are for people who already responded to and tolerated octreotide injection.
