Over the counter (OTC) allergy medications are frequently used by patients to treat hayfever and other common ailments. A recent recall of many Children's allergy medications has generated a bit of concern among parents and consumers.

Manufacturing defects have led to the recall of 43 child and infant liquid formulations of Tylenol, Motrin, Zyrtec, and Benadryl by McNeil, a division of Johnson & Johnson.

No injuries or deaths have yet been reported. The voluntary recall follows an April 19 FDA inspection of a McNeil plant in Fort Washington, Pa. that uncovered manufacturing deficiencies.

Apparently some of the products included in the recall may contain a higher concentration of active ingredient than is specified; others may contain inactive ingredients that may not meet internal testing requirements; and others may contain impurities.

If children who have taken the recalled products have unusual symptoms, parents are urged to contact a health care professional.

Parents should not give children adult formulation of the medications. Alternative brands of the products, including generic medications, are available. Parents who have questions about alternative treatments should consult their child's pediatrician.

Recent rumors suggest that Allegra products may soon be available OTC, without a prescription.
