A recall of Chlorthalidone tablets, a medication used by approximately 1.5 million Americans annually, has been upgraded to a Class II designation due to concerns that the drug may be ineffective and could lead to dangerous health consequences. The recall, initially issued on June 5 and classified on June 22, stems from "failed dissolution specifications."
This failure indicates a problem with how the tablets dissolve in the body, potentially leading to an incorrect dosage of the active drug being released. If a medication does not dissolve properly, it may not function as intended, posing risks to individuals managing medical conditions. Insufficient dissolution can result in the body absorbing too little of the drug, leading to untreated symptoms, while dissolving too quickly can cause side effects or safety issues.
Chlorthalidone is a prescription medication prescribed to treat high blood pressure and to reduce excess fluid retention associated with heart, liver, or kidney conditions. Roughly 5 million prescriptions are written for the drug each year.
A Class II recall signifies a situation where the use of a product may cause temporary or medically reversible adverse health effects, or where the probability of serious adverse health consequences is considered remote. Approximately 11,460 bottles of 25 mg Chlorthalidone tablets are included in this recall. The affected products are in 100- and 1,000-tablet bottles with an expiration date of April 2027. The 100-tablet bottles are identified by NDC 64980-599-01 and batch code RISA24001, while the 1,000-tablet bottles have NDC 64980-599-10 and batch code ISB24002. The medication is manufactured by Inventia Healthcare Limited and distributed by Rising Pharma Holdings, Inc.
While the Food and Drug Administration has not yet issued specific guidance for patients taking the medication, previous recalls of similar drugs have advised patients to contact their doctors urgently. Patients taking Chlorthalidone for high blood pressure that is not properly controlled could face risks of uncontrolled hypertension, which can lead to stroke, heart attack, heart failure, kidney damage, and blood vessel damage. Untreated fluid retention could result in worsening swelling, shortness of breath, and strain on the kidneys or heart.
Furthermore, if the drug does not work correctly, patients may experience side effects such as electrolyte imbalances, including low potassium, sodium, and magnesium levels. These imbalances can manifest as muscle weakness, fatigue, cramping, irregular heartbeat, confusion, seizures, headaches, reduced kidney function, low blood pressure, and elevated blood sugar levels.
