Too Much Thyroid Hormone Medicine
Some people who take thyroid hormone medicine for hypothyroidism may take too much. If you take thyroid hormone medicine, see your doctor at least once a year to have your thyroid hormone levels checked. You may need to adjust your dose if your doctor finds your thyroid hormone level is too high.
Some other medicines may also interact with thyroid hormone medicine and raise hormone levels. If you take thyroid hormone medicine, ask your doctor about interactions when starting new medicines.
Causes Of An Overactive Thyroid
There are several reasons why your thyroid can become overactive.
- Graves’ disease a condition where your immune system mistakenly attacks and damages the thyroid
- lumps on the thyroid this extra thyroid tissue can produce thyroid hormones, causing your levels to be too high
- some medicines such as amiodarone, which can be used to treat an irregular heartbeat

Surgical Removal Of The Gland Or Nodule
**Another permanent cure for hyperthyroidism is to surgically remove all or part.** Surgery is not used as frequently as the other treatments for this disease. The biggest reason for this is that the most common forms of hyperthyroidism are a result of overproduction from the entire gland and the methods described above work quite well in the vast majority of cases.
Although there are some Graves’ disease patients who will need to have surgical removal of their thyroid , other causes of hyperthyroidism are better suited for surgical treatment earlier in the disease.
One such case is illustrated here where a patient has hyperthyroidism due to a hot nodule in the lower aspect of the right thyroid lobe. Depending on the location of the nodule, the surgeon can remove the lower portion of the lobe as illustrated on the left, or he/she may need to remove the entire lobe which contains the hot nodule as shown in the second picture. This should provide a long term cure.
A potential down side of the surgical approach is that there is a small risk of injury to structures near the thyroid gland in the neck including the nerve to the voice box . The incidence of this is about 1%. Like radioactive iodine treatment, surgery often results in This fact is obvious when the entire gland is removed, but it may occur following a as well.

Side Effects Of Radioactive Iodine
The most common side effect of radioactive iodine is , or underactive thyroid, which occurs if the radioactive iodine destroys enough thyroid cells that the gland can no longer produce adequate thyroid hormone. In fact, almost everyone who has radioactive iodine treatment subsequently develops hypothyroidism.
It might seem odd to replace one disorder with another, but hypothyroidism is much easier to treat on a long-term basis than hyperthyroidism. If you develop hypothyroidism, you will need to take life-long , but it is a safe, reliable, and cost-effective treatment.
Other side effects of radioactive iodine can include:
A metallic taste in the mouth. This can last for a few weeks.
Nausea. This usually subsides one to two days after treatment.
Swollen salivary glands. This side effect can last for a few weeks and is caused by iodine absorbed by the salivary glands. Stimulating saliva flow a day after treatment is an effective remedy.
Contrary to information you may have heard or seen online, radioactive iodine therapy for hyperthyroidism or impair fertility. This treatment can be harmful to a fetus, however, so women who are already pregnant or hoping to conceive in the next 6 months will need to wait to have it until after they give birth .
Having Blood Tests During Treatment
You need to have blood tests before you start taking carbimazole and during treatment. These tests are important to check the levels of thyroid hormones in your body.
Depending on the results, your doctor may need to increase or reduce your dose to get these hormones to the right levels. When your levels are stable, you can usually go onto a lower dose, taken once a day.
When you first start treatment, you’ll have blood tests every 6 weeks or so. Once your hormone levels are stable, you’ll have a blood test every 3 months, for as long as you continue to take carbimazole.
However, you may need blood tests more often if you:

Treatments For Eye Problems
If you have thyroid eye disease but your symptoms arenât severe, you can usually manage them by avoiding bright lights and wind, raising the head of your bed, and using eye drops. Your doctor may suggest a selenium supplement. In some cases, your doctor might prescribe a medication called teprotumumab-trbw . Itâs FDA-approved to treat the symptoms of thyroid eye disease. They might also suggest steroids or other medications to help control the swelling behind your eyes.
For some people, especially those with severe thyroid eye disease, surgery is the best option. There are two kinds that can help severe symptoms:
- Orbital decompression surgery involves removing the bone between your sinuses and eye socket. It can make more room for your eyes so that they go back to their normal position. It can help improve your vision. There are risks to the surgery, including double vision.
- Eye muscle surgery is sometimes used to correct double vision. It works by cutting muscles in your eyeball that are covered in scar tissue. Thyroid eye disease can cause this. The cut muscles are then reattached in a different position, which can put your eyes back in proper alignment. You may need this surgery more than once to get the right results.

How Are Thyroid Problems Diagnosed
To diagnose thyroid conditions, your doctor will start with some blood tests to determine your levels of thyroid hormones. Once its been determined that your levels are either too low or too high , your doctor may then use other tests to determine the cause.
For hypothyroidism, this may include a test for a pituitary hormone called thyroid-stimulating hormone, or TSH, which our pituitary produces more of in an attempt to stimulate an underperforming thyroid. This may go along with a test to determine low levels of the thyroid hormone thyroxine, which would also indicate a slow thyroid.
For hyperthyroidism, an iodine uptake test, which traces the amount of iodine absorbed by the thyroid, may be used.
Other tests may include a thyroid scan, which is an imaging test in which your thyroid is checked for any abnormalities in size and shape or growths using an ultrasound machine. This may go along with a physical exam in your doctors office, where your doctor simply checks your neck for growths or enlargement of your thyroid.
Who Can And Cannot Take Carbimazole

Radioactive Iodine Uptake And Thyroid Scan
A radioactive iodine uptake test and thyroid scan help determine the cause of hyperthyroidism . Uptake is the percentage of an iodine 123 tracer dose taken up by the thyroid gland, ranging from 15% to 25% at 24 hours. The uptake is very low in patients with thyroiditis and high in patients with Graves disease, a toxic adenoma, or a toxic multinodular goiter.23,24
The thyroid scan shows the distribution of radiotracer in the gland. A homogeneous distribution indicates Graves disease, but accumulation of I-123 in one area points to a toxic adenoma or in multiple areas to a toxic multinodular goiter.23,24
Ultrasonography is sometimes used as a cost-effective and safe alternative to radioactive iodine uptake and scan. It is the primary imaging modality used during pregnancy, lactation, and in amiodarone-induced thyrotoxicosis.24

Treatments For An Overactive Thyroid
An overactive thyroid is usually treatable.
The main treatments are:
- medicine that stops your thyroid producing too much of the thyroid hormones
- radioiodine treatment where a type of radiotherapy is used to destroy cells in the thyroid, reducing its ability to produce thyroid hormones
- surgery to remove some or all of your thyroid, so that it no longer produces thyroid hormones
Each of these treatments has benefits and drawbacks. You’ll usually see a specialist in hormonal conditions to discuss which treatment is best for you.
How To Treat Overactive And Inflamed Thyroid Problems
The thyroid is a small, butterfly-shaped gland located at the front of the neck around the trachea, or windpipe. Its function is to secrete hormones necessary for many functions in your body, including controlling your metabolism, which is why it can affect your entire body if its not performing correctly.
This includes hypothyroidism, which is a condition in which the thyroid underperforms.

When Are The Different Treatments Used
If the thyroid gland is producing too many hormones, the first step of treatment is usually to slow down the production of hormones using medication. The hormone levels need to return to normal before other treatments can be started. If the overactive thyroid is being caused by “autonomous” thyroid cells, the next step of treatment is often radioiodine therapy. If the thyroid gland has become very large, surgery to remove it is usually recommended. In Graves’ disease, taking medication for several months is often enough to make the thyroid function return to normal. In about half of all people, the thyroid gland becomes overactive again when they stop taking the medication. Surgery or radioiodine therapy are then considered.
The choice of treatment doesn’t only depend on what is causing the overactive thyroid: For instance, the medication isn’t always well tolerated, and some people would rather not have surgery. It is then a good idea to discuss the available treatment options with the doctor.
What Is The Thyroid
The thyroid is a small gland below the skin and muscles at the front of the neck, at the spot where a bow tie would rest.
It’s brownish red, with left and right halves that look like a butterfly’s wings. It weighs less than an ounce, but helps the body do many things, such as get energy from food, grow, and go through sexual development.

Medication For An Overactive Thyroid
The most common medicines used to treat an overactive thyroid are carbimazole and propylthiouracil. These stop your thyroid producing excess hormones.
You’ll usually need to take the medicine for a month or 2 before you notice any benefit. You may be given another medication called a beta blocker to relieve your symptoms in the meantime.
When your thyroid hormone level is under control, your dose may be gradually reduced and then stopped. But some people need to continue taking medication for several years or possibly for life.
Treatment With Radioactive Iodine
Radioactive iodine may be given by mouth to destroy part of the thyroid gland. This is the most common treatment for hyperthyroidism. The radioactivity is mainly delivered to the thyroid gland because the thyroid gland takes up the iodine and concentrates it. Hospitalization is rarely necessary. After treatment, the person should probably not be near infants and young children for 2 to 4 days and should sleep in a separate bed separated at least 6 feet from the partner. Pregnancy should be avoided for about 6 to 12 months. People who have had radioactive iodine treatment should stay at least 6 feet away from pregnant women, infants, or small children for 6 to 23 days the amount of time depends on the dose received. People who have had radioactive iodine treatment may set off radiation alarms at airports and sometimes other places for several weeks after treatment and, therefore, should carry a doctors note describing their treatment if they travel on public transportation.

Common Questions About Carbimazole
When you have an overactive thyroid, also known as hyperthyroidism or thyrotoxicosis, your thyroid gland produces too much of the thyroid hormones. When these hormone levels are too high, you can have mood swings and weight loss.
Your thyroid gland uses a chemical called iodine to produce these hormones. Carbimazole blocks the way your body processes iodine and reduces the amount of thyroid hormones produced. This can then help your symptoms.
Carbimazole starts working straight away, but it can take 1 to 2 months before your symptoms improve and you start to feel better.
Once your thyroid hormone levels are under control, your dose of carbimazole may be gradually lowered and then stopped. Depending on your condition, you may need to take carbimazole for 12 to 18 months.
Some people need to continue taking the medicine for several years, possibly for the rest of their life.
However, if carbimazole is not working for you, your doctor may suggest alternatives such as radioactive iodine treatment or surgery to remove part or all of your thyroid.
Yes, it’s safe to take carbimazole for a long time, even many years.
It’s important to have regular blood tests during treatment, to make sure your dose is not too high or too low. Your doctor will make sure you are on the lowest dose that works for you.
Your doctor will be able to explain the risks and benefits of taking carbimazole, compared with the risks of not having treatment for your overactive thyroid.
