Armour Thyroid is a prescription medication used to treat hypothyroidism, or an underactive thyroid. It is in the form of a natural thyroid hormone, made from the desiccated thyroid glands of pigs. It is considered a natural form of thyroid hormone and is available in tablet form.

Armour Thyroid is a natural form of medication used to treat hypothyroidism since the 19th century. Hypothyroidism occurs when the thyroid gland malfunctions and fails to produce enough hormones necessary for metabolism, growth, and development.

Armour Thyroid is a medication that can be used for many thyroid-related health concerns. It is used to treat hypothyroidism, which is a condition where the body does not produce enough thyroid hormone. Additionally, it is sometimes used as part of thyroid suppression therapy, which is a treatment for thyroid cancer.

Uses and Dosage

Armour Thyroid is an oral medication that is taken once daily, ideally 30 minutes to 1 hour before breakfast. It should be taken on an empty stomach and swallowed whole, without crushing, chewing, or splitting the tablet. Drink a full glass of fluid after taking Armour Thyroid to ensure its effectiveness.

The dose of Armour Thyroid (desiccated thyroid) is typically determined by your healthcare provider, who will adjust the dosage based on your response to the medication and the results of your thyroid level lab tests.

  • For treatment of Hypothyroidism, the initial recommended dose is 30 mg orally per day. Depending on the individual's response and needs, this dose may be increased up to 120 mg per day. The starting dose for pediatric patients is determined by their age and body weight.
  • For Thyroid Suppression Therapy, the dosage is typically calculated by a healthcare provider based on the patient's body weight and administered for 7 to 10 days. It is important to follow the provider's instructions carefully and to monitor your progress regularly to ensure that the therapy is effective.

High doses can be dangerous and may cause serious or life-threatening side effects, especially when taken with sympathomimetic amines (e.g., drugs used for their anorectic effects).

Frequently Asked Questions (FAQ)

What happens if I miss a dose?

Take the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not take extra medicine to make up for the missed dose.

What should I avoid while taking desiccated thyroid?

If you also take cholestyramine (Prevalite, Questran) or colestipol (Colestid), avoid taking these medications within 4 hours before or after you take desiccated thyroid.
