Both Benadryl and Hydroxyzine are antihistamines commonly used to alleviate allergy symptoms, but they each have their own unique characteristics and uses. Benadryl is primarily aimed at treating allergic reactions and helping with sleep, while Hydroxyzine is often prescribed for anxiety and as a sedative. It's really important to consult with a healthcare professional before taking either of these medications, as they can cause side effects like dizziness, dry mouth, and drowsiness. Understanding their similarities and differences can help you choose the right option for your needs.
