The prognosis is favourable with several treatment options:
- Antithyroid drugs which are given daily
- Surgical excision of affected tissue, or
- Destruction of the thyroid tissue with radioactive iodine therapy
Medical management (option 1) is a requirement prior to options 2 & 3 in order to reduce the other complications (such as the effect on the heart and kidneys). This same treatment long term has gained popularity because it requires no special skills or facilities, is easy to implement and is relatively inexpensive. However, dosage is daily and there is a risk of difficulty with application; frequent monitoring by blood testing is also necessary.
Sometimes treating this condition can result in a decrease in kidney filtration rate and thus clinical signs of kidney failure.
It is important that regular check up’s are performed as well as a blood test every 6 months (or as indicated by your veterinarian) to monitor the patients response to the medication.
