Reactions to Armour Thyroid

Armour thyroid is a natural hormone used to treat hypothyroidism and, once started, is usually taken for life.

Allergic Reactions

• Allergic reactions are rare, but notify the doctor if you develop trouble breathing, dizziness, a rash, swelling or itching.

Estrogen

• Armour thyroid dosage needs may fluctuate upon the introduction of estrogen-containing drugs.

Breast Milk

• Small amounts of thyroid hormones are excreted into breast milk, and nursing mothers should discuss this with their doctor.

Patients with Diabetes

• Additional insulin may be needed when Armour thyroid therapy is introduced, so the patient should be monitored.

Pregnancy

• Thyroid hormone does not cross to the fetus, and thyroid replacement therapy should continue during pregnancy.

Hair Loss

• Temporary hair loss has been reported in children when Armour thyroid therapy is first introduced.

Oral Anticoagulants

• Armour thyroid can increase clotting factors, so patients may need reduction in anticoagulant dosage.
