What Is Cynomel 25mcg (Liothyronine)? Everything You Need to Know.

If you’ve been diagnosed with hypothyroidism or have thyroid-related symptoms that haven’t improved with levothyroxine (T4), your doctor may prescribe Cynomel 25mcg, a fast-acting thyroid medication that contains liothyronine sodium, the synthetic form of T3 (triiodothyronine) — the active thyroid hormone your body uses right away.

In this article, we’ll explore what Cynomel is, how it works, who it’s for, and why it’s gaining attention as a powerful option for thyroid hormone replacement.

What Is Liothyronine Sodium (T3)?.

Liothyronine sodium is a synthetic form of triiodothyronine (T3), one of the main hormones produced by the thyroid gland. Unlike levothyroxine (T4), which the body must convert to T3, liothyronine acts quickly and directly, making it ideal for patients who have trouble converting T4 to T3 naturally.

What Is Cynomel 25mcg Used For?.

Cynomel 25mcg is used to treat:

  • Hypothyroidism (underactive thyroid)

  • Goiter (enlarged thyroid gland)

  • Thyroid suppression tests

  • Certain cases of thyroid cancer

  • Metabolic issues related to low T3 levels


In some off-label cases, it’s also used under medical supervision for:

  • Fatigue and brain fog

  • Weight management in hypothyroid patients

  • Support in combination with T4 therapy

Who Should Use Cynomel?.

Cynomel is typically prescribed to:

  • Patients with persistent hypothyroid symptoms despite normal TSH levels

  • People who don’t respond well to levothyroxine (Synthroid or Euthyrox)

  • Individuals needing rapid thyroid hormone support

  • Patients with genetic or conversion issues affecting T4-to-T3 pathways

It’s not recommended for patients with untreated adrenal insufficiency or serious heart conditions without close medical supervision.

How Is Cynomel 25mcg Taken?.

Cynomel is usually taken once daily, but dosage and frequency can vary depending on individual needs. A typical starting dose may range from 5mcg to 25mcg daily, with adjustments made gradually.

Because liothyronine is fast-acting, some patients split the dose to maintain stable energy throughout the day.
