Key takeaways
Levothyroxine/liothyronine (Adthyza) and desiccated thyroid (Armour Thyroid) are both medications used to treat hypothyroidism and other thyroid-related conditions. They belong to the same drug class, thyroid hormone replacement, and are taken orally. Both medications are derived from animal sources, which some people prefer as a natural option. Both contain a combination of T3 and T4. However, there are key differences between them. Adthyza is typically started at a dose of 32.5 mg per day for adults, whereas Armour Thyroid starts at 30 mg per day. Both medications require careful monitoring of thyroid levels and are not FDA approved. Side effects most commonly happen when thyroid levels get too high, which can lead to symptoms like nervousness and a fast heartbeat. Additionally, both medications can interact with other drugs, such as diabetes medications and blood thinners, so it's important to discuss all medications you are taking with your healthcare provider.
