New York, May 24 (NationPress) The US Food and Drug Administration (FDA) has alerted the public that certain widely-used allergy treatments may trigger a rare yet serious itching side effect.
In a safety notice released in mid-May, the FDA indicated that some individuals who have utilized oral allergy medications daily for extended periods—typically several months to several years—have reported experiencing a severe form of itching known scientifically as pruritus, according to Xinhua news agency.
The FDA specifically cautioned about the potential for rare but severe itching following the cessation of long-term use of oral allergy medications such as cetirizine or levocetirizine (marketed under names like Zyrtec and Xyzal). This side effect can manifest with both prescription and over-the-counter versions of these drugs, the agency noted.
Though instances of severe itching are uncommon, some cases have been serious enough to necessitate medical treatment.
Both cetirizine and levocetirizine are available either through prescription or over-the-counter (OTC). The FDA has updated the prescribing guidelines for these medications to include a warning regarding the potential side effects.
The agency stated, “We will subsequently request that manufacturers add a warning about pruritus to the Drug Facts Label of the OTC versions.”
These antihistamines work by blocking a molecule called histamine that the body produces during allergic reactions. Both medications are approved for treating seasonal allergies, known as seasonal allergic rhinitis, in adults and children aged 2 and older.
Additionally, they are approved for managing year-round allergies, termed perennial allergic rhinitis, as well as chronic hives, also referred to as chronic idiopathic urticaria, in patients aged six months and older.
Cetirizine received approval for oral use by prescription in December 1995 under the brand name Zyrtec (which is no longer available as a prescription medication) and was approved for OTC use in November 2007.
Levocetirizine was approved for prescription use in May 2007 under the brand name Xyzal and received OTC approval in January 2017.

The FDA's warning about the itching side effects of common allergy medications emphasizes the need for transparency and vigilance.
