FDA Recalls Popular Thyroid Medication: What Levothyroxine Users Need to Know

Millions of people with hypo<span>thyroid</span>ism depend on <span>levothyroxine</span> every day to replace the thyroid hormone their body cannot produce. 

Now, the U.S. <span>Food and Drug Administration</span> (<span>FDA</span>) has announced a nationwide recall of certain batches of levothyroxine sodium tablets after they were found to be subpotent, meaning they contain less active medication than stated on the label.

Experts caution that ingesting a lower-than-prescribed dose could allow <span>hypothyroidism</span> symptoms to return, particularly in vulnerable groups like pregnant women, infants, and people with <span>thyroid cancer</span>.

<h2>Why Did FDA Recall Levothyroxine?</h2>

The FDA has issued a Class II recall for specific lots of levothyroxine sodium tablets distributed by Major Pharmaceuticals. Testing found that the recalled tablets were below the approved potency specification, meaning they may not deliver the intended amount of <a href="https://www.healthandme.com/health-wellness/think-you-have-pcos-these-3-symptoms-could-help-clear-the-confusion-article-151174652" data-type="tilCustomLink">thyroid</a> hormone.

The recall affects multiple strengths packaged in 100-tablet cartons and 10-count blister packs. Dosages involved include 25 mcg, 50 mcg, 75 mcg, 88 mcg, 112 mcg, 125 mcg and 150 mcg. 

The FDA has categorized the action as a Class II recall. According to the agency, a Class II recall means: "Use of, or exposure to, a violative product may cause temporary or medically reversible adverse health consequences or where the probability of serious adverse health consequences is remote." 

This means the recall is important but does not come under FDA's highest-risk category.

<h2>Why A Subpotent Thyroid Medicine A Concern?</h2>

Even relatively small differences in levothyroxine dose can affect how well the medicine works. If they contain less hormone than needed, patients may receive insufficient <a href="https://www.healthandme.com/health-wellness/silent-neck-swellings-why-an-unusual-lump-should-never-be-ignored-article-155174950" data-type="tilCustomLink">thyroid replacement</a>. Possible consequences include:

<ul><li>Fatigue</li><li>Weight gain</li><li>Feeling unusually cold</li><li>Constipation</li><li>Depression or low mood</li><li>Brain fog</li><li>Dry skin</li><li>Slower heart rate</li></ul>

In some higher-risk individuals, inadequate thyroid hormone replacement could have more severe consequences, including worsening hypothyroidism or interference with thyroid cancer treatment.

<h2>What Does This Recall Mean For Patients?</h2>

<a href="https://www.healthandme.com/health-wellness/covid-19-in-india-omicron-rf-5-primarily-affects-throat-unlikely-to-trigger-pneumonia-in-healthy-people-say-experts-article-155138964" data-type="tilCustomLink">Levothyroxine</a> is the synthetic form of thyroxine (T4), a hormone normally produced by the <span>thyroid gland</span>. Doctors prescribe it to treat hypothyroidism, goiter, certain thyroid cancers after surgery, and conditions requiring suppression of thyroid-stimulating hormone (TSH) 

Because thyroid hormone influences nearly every organ system, taking the correct dose consistently is essential.

Do not stop taking levothyroxine on your own. Stopping thyroid medication suddenly can lead to worsening hypothyroidism and other complications. Instead, patients should:

<ul><li>Check whether their medication's lot number matches the recalled batches.</li><li>Contact your pharmacist or physician.</li><li>Obtain a replacement if their medication is affected.</li><li>Continue treatment unless instructed otherwise by a healthcare professional. </li></ul>

<h2>Other Recently Recalled Medications</h2>

The FDA also announced recently that it is recalling four lots of Cetirizine Hydrochloride Tablets USP 5 mg made by India-based company Unique Pharmaceutical Laboratories due to potential cross-contamination with ranitidine, a medication used to treat heartburn and stomach ulcers.

Although Unique Pharmaceutical Laboratories said it has not received any reports of adverse reactions related to the recalled tablets, the contamination could pose a serious risk for people who are allergic or hypersensitive to ranitidine.

For anyone taking levothyroxine, experts recommend checking medication packaging against the FDA recall notice and speaking with a healthcare provider or pharmacist if there is any uncertainty.
