RLC Labs Inc.: Nature-Throid and WP Thyroid Tablets Recalled for Subpotency

Agency Publication Date: September 15, 2020

Sign in to monitor this recall

Summary

RLC Labs Inc. is recalling all lots of Nature-Throid and WP Thyroid (thyroid USP) within their expiration dates because they are subpotent, meaning they contain less active medication than required. These prescription medications are used to treat an underactive thyroid (hypothyroidism). The recall affects various strengths ranging from 1/4 grain to 3 grains, sold in bottle sizes from 30 to 1,000 counts. Testing by the FDA confirmed that the products do not meet the potency specifications, which could result in patients receiving an insufficient dose of thyroid hormones.

Risk

Patients taking subpotent thyroid medication may experience symptoms of hypothyroidism, such as fatigue, weight gain, constipation, depression, and increased sensitivity to cold. For vulnerable populations like pregnant women or the elderly, an inadequate dose of thyroid hormone can lead to more serious health complications, including heart issues or developmental problems for a fetus.

What You Should Do

  1. Check your prescription bottles to see if you have Nature-Throid or WP Thyroid (thyroid USP) manufactured by RLC Labs.
  2. Identify if your product is affected by looking for lot numbers with expiration dates between October 2020 and July 2023, or specific lot numbers 119142, 099186, 109242, 109032, 109264, or 109286.
  3. Consult your healthcare provider or pharmacist immediately before you stop taking the medication, as stopping thyroid treatment abruptly can cause health issues.
  4. Ask your doctor for a replacement prescription for a thyroid medication that is not affected by this recall.
  5. Return any unused tablets to the pharmacy where you purchased them for a refund.
  6. If you have experienced any health problems while taking these products, contact your healthcare provider and report the incident to the FDA's MedWatch program.
  7. For further questions regarding the recall, contact the FDA Consumer Complaint hotline at 1-888-723-3332 (1-888-SAFEFDA) or visit www.fda.gov/safety/recalls.
