Antihistamines are a group of medicines often used in both human and veterinary medicine. They are used to relieve the symptoms of allergic disorders such as hay fever, hives and reactions to insect stings and bites.
In overdose, antihistamines can cause drowsiness or hyperactivity (depending on the drug), vomiting, wobbliness, increased body temperature, increased heart rate and weakness.
It is important that you DO NOT try and self medicate your pet at home with antihistamines without consulting your veterinary surgeon first
