Epilepsy is an important neurological disorder in dogs. Belladonna 200C was evaluated in 10 dogs with idiopathic epilepsy. During the seizure phase, 3-4 drops of Belladonna 200C were administered orally at 15 min intervals until considerable reduction in seizure activity, then four times daily. Four dogs with head shaking syndrome in addition to seizures were given Cocculus 6C, 3-4 drops orally weekly for 3 months in addition. Numbers of fits reduced to 2-3 during first 2 weeks post-therapy and then became occasional in next 2 weeks. With continuation of Belladonna therapy, no fits were observed during 2-7 months follow-up. In two cases epileptic fits reappeared within 15-25 days of cessation of therapy. Belladonna therapy was resumed and seizure control was again achieved. Owners were advised to continue the therapy at least twice daily until there were no fits for 2-3 months. Liver specific enzymes were monitored, no abnormalities were observed.
