Important Notice Regarding NP Thyroid

Many of our patients are just becoming aware that there is a manufacturing issue with the production of a commonly prescribed thyroid medication – NP Thyroid and a recall has been issued. You may have been notified by your pharmacy already.
Please know we are here to assist you and our local pharmacies during this recall.
Read the information below on what this means and what you can do.

Treating your Thyroid is more than just a medication

The hormones produced by the thyroid have an impact on nearly every single tissue and organ in the body. Thyroid hormones are vital in how your body uses energy, regulates body temperature, controls metabolism, and maintains optimal health within the brain, heart, GI tract, muscles, and other organs.
Diet, exercise, strategies for treating gut health, detoxing, optimal supplementation to support thyroid function, as well as additional testing and resources within our office, are all an important part of how we approach treatment of thyroid.
