While much of the United States may still be experiencing the harsh temperatures of winter, spring is only a few weeks away. Unfortunately, warmer days also mark the coming of something else: seasonal allergies. Many people suffer from this condition—something that drug companies are well aware of, if the number of allergy relief products lining drugstore shelves is any indication. Recent events, however, may alter what medications will be available over the counter in the near future. Earlier this year, a major pharmaceutical company had to recall its OTC versions of two popular allergy medications. One of the drugs was found to potentially contain an impurity while the other may have incorrect dosing markings. The recalled medications aren’t actually suspected of any harmful contamination, but no one wants to risk administering a potential overdose.
