No, usually when first diagnosed a test is done every six to eight weeks. 3 months is too long. It's the first I've heard of 'legal procedures'. Other member will also respond.
Why do doctors try to scare patients into conforming to their (GPs ideas) instead of concentrating on the patient.
Of course, if we upped the dose of levothyroxine every week we might feel very overdosed. That isn't quite the same as 50mcg to start with 25mcg every six weeks which is the norm. Some increase every 8 weeks. The fact is it is the symptoms we have which we want relief of that should take priority. Usually when we begin a dose we will feel symptoms returning quickly (symptoms might well remain with a starting dose) so we need an increase.
Blood tests should be at the very earliest, fasting (you can drink water), allow a gap of 24 hours between your last dose of levo and the test and take it afterwards. This keeps TSH at its highest as some doctors reduce our dose if TSH is low.
Always ask for a print-out of your results, we are entitled by Law and some surgeries charge a nominal sum for paper/ink/. You can post if you have a query but ranges are important to be quoted too.
Your doctor should test B12, Vit D, iron, ferritin and folate as deficiencies also cause symptoms.
Read members questions etc and you will learn quite a lot as doctors seem to be the least educated in the function of the thyroid gland and hypothyroidism. We have to absorb information in order that we return to good health despite the guidelines in force at present.
