Questions and answers on "Carbimazole"

I am 70 year old female aged 70. On Tuesday I was treated with an Iodine tablet due to an overactive thyroid. I am due to commence Carbimazole 5 mg tablets today (Friday). I have read up on some of the side effects and have found that I have been experiencing most of these problems before commencing on the Carbimozole tablets. I have in later years had swollen stomach (gas), nausea, feeling of being generally unwell and I do not wish to continue on this feeling of being unwell day by day. Am I following the correct procedures to getting on top of this feeling unwell. I am also concerned about the increase in weight that some people have reported as I have always eaten a healthy diet and would like to remain the weight that I am.

I want to know, is thyronorm and thyroup 12 used for under active or over active thyroidism?? My dad is diagnosed with hyperthyroidism, but the doctor has prescribed these two drugs for him. while i google search about the drugs and the results showed they are for under active, whereas my dad needs a drug that reduces the thyroid secretion.

We need a second opinion...

My sister has been diagnosed with overactive thyroid, heat intolerance, diarrhea, high pulse and heart palpitations.

The doctor has subscribed proporonal up to 3-4 times a day for her heart (10mg), Loratadine (10mg) and carbimazole (20mg).

Could you tell us, do these medicines need to be taken for a life time, what are the implications of doing so, are there any chances of recovery? Other information which may be helpful to us.

She has been referred to a consultant, xray for the neck (thryoid gland) is next week.

Thank you.

I hope either Technetium scan of thyroid or Radio iodine uptake was done before starting the medicines.

If the diagnosis is hyperthyroidism (Graves' disease -specifically) then the treatment with Carbimazole for 12 - 18 months will cause remission in...

The low TSH levels with almost normal T3 and T4 levels is suggestive of subclinical hyperthyroidism.

I am a 29 year old woman recently diagnosed with hyperthyroidism. T3 and T4 level were 16.7 and 41.9 pmol/L respectively and TSH was 0.01mIU/L. The same blood test revealed negative pregnancy.
My doctor prescribed Propranolol and Carbimazole and described me they are category C for use in pregnancy. So he advised me not to fall pregnancy until it is cured.
I am very eager to have baby. Are there other safe medications to control my symptom and not affecting pregnancy?
Also, the blood test was on 18th XXXXXXX I had sexual relation on 7th, 9th, 10th and 12th. I predicted m ovulation was on either 8th or 9th according to 'body temperature graph".

Welcome to healthcare Magic!
There are only two drugs the carbimazole/methimazole and propylthiouracil for hyperthyroidism which take about 1-2 years to control the problem fully.
Both are contraindicated in pregnancy.
The adverse effect of propylthiouracil are more.
You should repeat...
