Pexion 400mg tablets are a treatment for dogs with primary epilepsy or dogs with noise phobias. It acts on a specific receptor in the brain cells to reduce the amount of excessive electrical activity present. In this way, like all epilepsy treatments, Pexion acts to reduce the number of seizures that your dog has and their impact on your dog's life.
Each Pexion tablet is white, oblong and half-scored with embedded logo “I 02” (400 mg) on one side. The tablet can be divided into equal halves. One tablet contains 400 mg of the active substance imepitoin.
