The Food and Drug Administration (FDA) is adding a new warning for two commonly used allergy medications after some users reported experiencing severe itching after discontinuing the drugs.

Some patients who stopped using cetirizine, known as Zyrtec, or levocetirizine, known as Xyzal, suffered severe itching, the FDA said in a May 16 safety alert.
