Rarely the changes can be more severe, making the eyes very prominent and causing double vision. If this happens you will need to see an eye specialist. It is known that smokers are more likely to get eye changes than those who do not smoke.
This tablet reduces the amount of thyroid hormone being made by the thyroid gland and takes two to three weeks to become fully effective. Usually a higher dose is used at the start (20 to 40 mg once daily) and then the dose is progressively cut down to a maintenance dose (5 to 10 mg daily).
Very occasionally a higher dose is started and maintained (60 mg daily). This then has to be supplemented by a thyroid hormone tablet (Thyroxine) to maintain normal thyroid hormone levels in the blood stream. This is called the 'block and replace' regimen.
