Some patients may require treatment with both levothyroxine (T4) and liothyronine (T3), the two main thyroid hormones. This can occur when a patient continues to experience symptoms of hypothyroidism even though their TSH levels are within the normal range. Here's the reasoning behind this:

1. Levothyroxine (T4) is the inactive form of the thyroid hormone.
2. The body converts T4 to the active form, triiodothyronine (T3), in various tissues throughout the body.
3. In some individuals, the conversion of T4 to T3 may be impaired. This can happen due to certain health conditions or medications.

Therefore, even if a patient's TSH levels are normal on T4 therapy alone, they may still experience symptoms because they aren't getting enough active T3 hormone in their tissues.

A doctor may consider adding liothyronine (T3) therapy to a patient's treatment plan in such cases to improve their symptoms.

NP Thyroid is a prescription medication, so you'll need to talk to your doctor to see if it's the right option for you.

This medication is intended for individuals with specific thyroid disorders and should only be taken under the supervision of a healthcare professional. Doses are carefully calibrated based on regular blood tests to ensure optimal treatment and safety. Misusing this medication for weight loss by people with normal thyroid function can lead to serious and potentially life-threatening side effects. Always consult a doctor before taking any medication, especially medications that alter hormone levels.
