"Fen" my cat is 8/9 years old and has just been diagnosed with an over active thyroid and poor kidney function. The vet prescribed Fortekor 2.5mg once per day. She said that it would be best to get the kidneys sorted before we put Fen on any thyroid treatment.I gave Fen her first tablet on Thursday and after a few hours She looked a bit dizzy ,told vet about this but She said that She had not heard of this before.
Later that night Fen became very sleepy and was not eating. Gave Fen second tablet and she has started to become worse. Phoned vet again on saturday and decided to stop giving the tablets. Fen has not eaten all day all She wants to do is sleep and I have noticed that she has started to tremble, like she is cold.
Before Fen started the tablets she was eating lots and lots , playing, purring all the time and very talkative. We took her to the vets because she was eating and drinking a lot but losing weight.
Has anyone out there come across these side effects with Fortekor? please help my little fur baby!
