Urgent Chlorthalidone Recall 2026: Check Your Blood Pressure Medication Lot Numbers Now

Urgent FDA Alert: 11,460 Bottles of Chlorthalidone Blood-Pressure Tablets Pulled for “Failed Dissolution” The U.S. Food and Drug Administration has announced a nationwide recall of chlorthalidone tablets—a staple diuretic used for hypertension—after tests showed the pills may not dissolve properly, putting patients at risk of uncontrolled blood pressure and fluid retention. Key details at a glance • Drug name: Chlorthalidone Tablets USP, 25 mg • Manufacturer: Inventia Healthcare Limited (India) • U.S. distributor: Rising Pharma Holdings, Inc. • Lot numbers / package sizes: • RISA24001 – 100-tablet bottles (NDC 64980-599-01) • RISB24002 – 1,000-tablet bottles (NDC 64980-599-10) • Expiration date: 04/2027 • Total affected: 11,460 bottles shipped to pharmacies nationwide Why “failed dissolution” matters Dissolution testing measures how quickly a tablet releases its active ingredient in the body. If the process is too slow or incomplete, the dose your physician intended may never reach therapeutic levels, raising the danger of stroke, heart attack or kidney damage for people relying on chlorthalidone to keep blood pressure in check. What patients should do now 1. Grab your prescription bottle and compare the NDC, lot code and strength to the list above. 2. Do not stop taking chlorthalidone abruptly; sudden withdrawal can spike blood pressure. Instead, contact your pharmacist or prescriber immediately to arrange a replacement or alternative therapy. 3. Report any side effects—headaches, dizziness, swelling or rapid weight gain—to the FDA’s MedWatch portal. Pharmacy & prescriber guidance Healthcare professionals should quarantine stock from the implicated lots, notify affected patients, and arrange returns through their supplier. Follow standard Class I–III recall protocols until the FDA assigns a formal hazard classification. Why this recall is significant Chlorthalidone is often preferred over hydrochlorothiazide because of its longer half-life and proven cardiovascular benefit. With over 1 million U.S. prescriptions filled monthly, even a “quality-control” recall can disrupt treatment for thousands of hypertensive and heart-failure patients. How to stay protected • Opt into text or email alerts from your pharmacy for real-time drug safety updates. • Check the FDA Enforcement Report weekly if you take multiple chronic-care medications. • Store pills in original containers so lot and NDC numbers remain legible. Bottom line If your bottle matches the recalled lot, call your doctor today. Swift action will keep your blood pressure goals on track while regulators and manufacturers correct the manufacturing issue.
