Nature-Throid Patient Guide: Accessing Your Medication

Important Notice About Nature-Throid Availability

As of 2024, Nature-Throid has been discontinued by RLC Labs and is no longer available[7]. This guide provides historical information about the medication and RLC Labs' patient assistance efforts. If you were taking Nature-Throid, please consult your healthcare provider about alternative thyroid replacement medications.

About Nature-Throid

Nature-Throid is a desiccated thyroid replacement medication used to treat hypothyroidism (underactive thyroid)[1]. First released in the 1930s, it was one of the earliest available medications for this condition[2]. The medication contains both liothyronine (T3) and levothyroxine (T4), the active thyroid hormones needed to regulate metabolism and energy levels.

Important Recall Information

In September 2020, RLC Labs issued a voluntary recall of all lots of Nature-Throid due to subpotency issues[1][3]. FDA testing found that some lots contained as little as 87% of the labeled amount of active ingredients[1]. This recall affected 483 lot numbers dating back to 2017[3]. If you have Nature-Throid from this period, contact your healthcare provider or RLC Labs immediately.

What to Do If You Were Taking Nature-Throid

Do not stop taking your thyroid medication without consulting your healthcare provider[1]. Discontinuing thyroid replacement therapy can lead to serious health complications. Instead:

1. Contact your prescriber to discuss alternative thyroid medications
2. Ask about generic levothyroxine (synthetic T4), which is widely available and typically more affordable
3. Explore other desiccated thyroid options if your doctor recommends them
4. Request a new prescription for your replacement medication

Alternative Thyroid Medications

If Nature-Throid is unavailable, your healthcare provider may recommend:

• Levothyroxine (Synthroid, generic): Synthetic T4 only; most commonly prescribed thyroid replacement
• Liothyronine (Cytomel): Synthetic T3 only
• Combination T4/T3 therapy: Prescribed when both hormones are needed
• Other desiccated thyroid products: If available and appropriate for your condition

Many of these alternatives have generic versions covered by insurance or available at low cost through pharmacy discount programs.

If You Need Financial Assistance

Since Nature-Throid is discontinued, explore these resources for your replacement medication:

• Manufacturer assistance programs: Contact the manufacturer of your new thyroid medication
• Pharmacy discount programs: GoodRx, SingleCare, and similar services often provide significant savings on thyroid medications
• State pharmaceutical assistance programs: Many states offer programs for uninsured or underinsured residents
• Community health centers: Federally qualified health centers often provide medications at reduced costs
• Medicare/Medicaid: If eligible, these programs cover thyroid medications
