Viral hives often itch like crazy and can cover more than a small area of the body. You can have viral hives on your arm for a few minutes, only to see them move to your shoulder or even your stomach.
Highs from a range of sources (natural or induced) can be exciting and compelling. But, there are definitely both short-term and long-term effects of using diphenhydramine, the active ingredient in many antihistamines, (like Benadryl) that are worth noting. Diphenhydramine and other antihistamines affect your central nervous system, which is why the list of possible effects is so long and broad â people may react to the same stimulus in various different ways. Some possible short-term effects include: Light-headedness; Loss of coordination; Dry nose, throat, and mouth; Blurred vision
What I found is that Benadryl is used for a host of purposes including: 1  Controlling itching. 2  Help stop vomiting. 3  Motion sickness. 4  A mild tranquilizer. 5  Snake bites. 6  Vaccination reactions. 7  Insect bites or bee stings. 8  Blood transfusion reactions.
