FDA Warns About Severe Itching After Stopping Popular Allergy Medications
The U.S. Food and Drug Administration (FDA) has issued a warning regarding the potential for "rare but severe itching" (pruritus) in patients who discontinue long-term use of the popular oral allergy medications Zyrtec (cetirizine) or Xyzal...
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.
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 and levocetirizine are antihistamines that work by blocking histamines released by the body during allergic reactions. 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.
