My Mr. Bean has hyperthyroidism. Our vet gave us Tapazole. He's to get 1/4 of a pill twice a day. I gave him 3 doses and then he started vomiting. The vet then gave us Reglan. I simple stopped giving him anything. My vet is gone until 6/6. Has anyone had experience with the timing of this medication or method of administering to reduce the side effects. Also, he quit pooping. What about constipation? He really seemed like he felt ill on the medicine. Is this just temporary? Help!
