#Diphenhydramine

Millions of people across the globe rely on Benadryl, a common over-the-counter allergy medication, for relief from runny noses and itchy skin. However, a fresh wave of scientific evidence is raising serious concern about the long-term safety of its key ingredient, diphenhydramine. A recent study and mounting medical warnings have drawn direct links between regular Benadryl use and a higher risk of developing crippling diseases such as dementia and Alzheimer’s, prompting doctors to urge consumers, including those in Thailand, to reconsider their treatment choices.
