Versatile Vetadryl is an antihistamine recommended by veterinarians to treat a range of issues including allergies, motion sickness, travel anxiety – even insect bites that cause itching and pain. The active ingredient in Vetadryl is diphenhydramine. This chemical blocks the histamines that cause allergic reactions such as itching, watery eyes, runny noses and swelling. One side effect of the histamine blocking process is sleepiness, which is why this medication also works to calm pets and reduce motion sickness. Talk to your veterinarian about whether Vetadryl is right for your pet’s condition. Vetadryl is available in 10 and 30 mg flavored tablets. Have a question about Vetadryl?
