A rare but severe reaction from certain allergy medications has prompted a warning from the Food and Drug Administration (FDA). The agency is cautioning that stopping long-term use of medications like Zyrtec or Xyzal can lead to severe itching. This side effect appears to affect individuals who have used these medications for an extended period. In response, the FDA is urging manufacturers to include this new warning on their packaging to alert consumers to the potential risk.
