I have a 14 year old cat with hyperthyroidism. He is on Methimazole 2.5 mg. 2×day. He used to be loving and cuddly but now he's lethargic and just goes off by himself. Has anyone else had this or other problems with this med?
I have a 14 year old cat just started on thyroid medication. 2.5 mg. 2 times a day. He acts like he is a zombie after medication for hours! Stares at the walls like he's stoned. When will this go away? My vet does not seem at all worried.
