Summary
This study looked at how a common allergy medicine, diphenhydramine (Benadryl), affects thinking and alertness when given through an IV. Researchers tested memory, reaction time, and attention in healthy adults aged 35–50 or over 65. The study was stopped early and only included 3 people, so results are very limited.
