FDA Warns About Severe Itching After Stopping Popular Allergy Medications
Key Insights
The FDA reported 209 cases worldwide (197 in the U.S.) of pruritus after halting use of cetirizine or levocetirizine between April 2017 and July 2023.
Patients had typically used these medications daily for at least a few months, and often for years, before experiencing itching upon cessation.
The itching can significantly impact quality of life, in some cases leading to disability, hospitalization, or thoughts of self-harm.
The FDA estimates that in 2022, 26.8 million prescriptions for cetirizine and levocetirizine were dispensed, with an additional 62.7 million over-the-counter (OTC) products purchased.
Why this matters: Millions of Americans rely on Zyrtec and Xyzal to manage allergy symptoms. This new warning provides crucial information for both patients and healthcare providers regarding the potential risks associated with discontinuing these medications after prolonged use.
In-Depth Analysis
The FDA's warning is based on an analysis of adverse event reports indicating a possible causal relationship between stopping cetirizine or levocetirizine and the onset of pruritus. While the exact mechanism behind this phenomenon remains unknown, the agency is requiring manufacturers to add a warning to both prescription and OTC labels.
Background Context:

Cetirizine was initially approved as a prescription drug in 1995 and became available over the counter in 2007. Levocetirizine was approved for prescription use in 2007 and switched to over-the-counter status in 2017.
How to Prepare:
Individuals planning long-term use of Zyrtec or Xyzal should discuss the benefits and risks with their healthcare provider.
Patients experiencing severe itching after stopping these medications should contact their healthcare provider.
Restarting the medication or tapering off the dose after restarting may help resolve the itching.
