Visiting your Doctor


Visiting your Doctor


Once you have been diagnosed, try to see the same doctor every time you make an appointment. It makes it much easier to discuss your progress.

Be aware that if you are diagnosed with hypothyroidism (underactive thyroid), you are entitled to free prescriptions.  Ask your GP or NHS hospital for an FP92A application form. The form tells you what to do. A certificate/card will be sent to you upon receipt of a properly completed application form.

If your doctor diagnoses you with thyroid disease, they will probably start you on treatment with levothyroxine immediately. Levothyroxine is a synthetic form of the thyroid hormone that your body makes – thyroxine.

Treatment is usually started with small dosages of 25mcg or 50mcg.  You will probably be told to be tested again in two or three months’ time and then make another appointment to see your doctor.  Your doctor will then look at your test results, discuss your symptoms with you again, especially any improvement, and then make a decision as to whether or not to increase or decrease your dosage.

Your doctor will, at some point, decide when to keep you on a particular dosage.  This is usually decided by looking at the blood test results as well as whether your symptoms have been resolved.

However, some people do not resolve all of their symptoms on levothyroxine alone.
