protocol for treating hyperthyroid cat who has an ongoing heart murmur
- Hello out there. My Oreo was just diagnosed as having a hyperthyroid
Here is the data from her lab tests of the past week:
t4 level 9.7
heart murmur 3 from scale of 1-6 ( I believe it has always been about a 2 before)
Issue' Would a 1.25 mg twice a day of tapazole be safe for her considering she has a heart murmur. My vet originally prescribed 5 mg. bid, but from a # of sources I understand this is outdated protocol and it is one should start out slowly and begin with 1.25 mg bid.
The vet on duty whom I later spoke to said " if I wanted I could do 2.5 mg bid ( But at their clinic they do 5mg bid " because it works".I have heard that the result of a high dose can cause hypothroidism with dire consequences and that, with cats , unlike dogs the cats vary in their reaction to the dosage and that therefore it is better to proceed
conservatively and gradually increase the dosage if called for.
But I don't want to put Oreo's hear health in jeopordy (sp?). Her vet said she is more concerned about her heart than the thyroid problem.
Thanks so much for your input.

Hyperthyroid is a cause of secondary HCM. It may be when the thyroid is
treated, the heart condition gets better. My Josh got a lot better when he was
treated. We went straight onto the 5mg and after a few weeks he had his
thyroid measured again to check it wasn't too low.
