How to Avoid Double Dosing on Medicines This Season

Cold and flu season has returned like clockwork. As you hit the over-the-counter aisle, rummage through your medicine cabinet at home, and prepare to combat your family’s runny noses and sore throats, remember to double check medicine labels so you don’t accidentally double up on medicines containing acetaminophen. Research published this year shows that consumers don’t always know the potential risks of double dosing on medicine or that taking two medicines with the same ingredient could be harmful.

Allergies and hay fever are unpleasant enough on their own, but now they — and the nasal symptoms that accompany them — appear to be linked to more frequent and more disabling migraine attacks, according to a recent NHF-sponsored study. Researchers, led by Vincent Martin, MD, a professor of medicine at the University of Cincinnati and co-director of the university’s Headache and Facial Pain Program, found that two-thirds of migraineurs reported suffering from allergies and were 33 percent more likely to have more frequent migraines than those without allergies.
