When you have watery eyes or an itchy nose, an antihistamine such as Tavist can work wonders. The same is true for your dog. If Pal's suffering from an allergic reaction, an antihistamine will help his symptoms. A quick call to the vet can inform you how much and how long to use this medication.
Clemastine vs. Histamine
When Pal's body releases the chemical histamine, it's responding to an allergic reaction or inflammation -- such as swelling or itching from a bug bite or bee sting. An antihistamine will block the effects of the chemical reaction. If Pal has such a reaction, the vet may recommend clemastine, the generic name for Tavist. Yes, the same Tavist you have in your medicine chest is OK for your pup. Though it's only approved for human use by the Food and Drug Administration, veterinarians often recommend Tavist to relieve symptoms caused by histamine attacks in dogs. Conditions such as itchy skin and reactions to vaccinations or blood transfusions are often soothed by a dose of clemastine. Tavist does carry some side effects, including vomiting, lethargy, decreased appetite and diarrhea. If Pal has high blood pressure, glaucoma or heart or lung disease, he shouldn't take clemastine. As well, it can interact with other medication, so you should always contact your vet before giving Tavist to your pup. The vet will let you know the safe dosage for Pal.
