About This Medication

# 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. ## RLC Labs Patient Assistance Contact Information While specific patient assistance program details are not publicly documented in available sources, RLC Labs provided customer support through the following channels: - **Phone**: 1-877-797-7997 (Monday-Thursday, 7:00 AM to 4:00 PM MST; Friday, 7:00 AM to 3:00 PM MST)[5] - **Email**: customerservice@rlclabs.com[6] - **Recall-Specific Email**: recall@rlclabs.com[5] ## 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 ## Important Disclaimer This guide is provided for informational purposes only.
