What was the effect of propylthiouracil?
Propylthiouracil may cause severe liver damage in adults and children. Some people who took propylthiouracil needed liver transplants and some people died because of the liver damage.
What is the most serious adverse effect of propylthiouracil?
Propylthiouracil can cause liver damage (especially during the first 6 months of treatment). Liver failure can be fatal or may require a liver transplant.
What are the long term effects of carbimazole?
A very rare but serious side effect of carbimazole treatment is reduced production of white blood cells by the bone marrow. This makes you more vulnerable to infections. The first sign that this might be happening may be a very sore mouth or throat, with severe ulcers, for no other obvious reason.
Why is carbimazole bad?
Carbimazole can cause a drop in your white blood cells, which fight infection – a condition is called neutropenia. This can put you at increased risk of getting infections.
Does carbimazole affect immune system?
Levothyroxine used to treat an underactive thyroid (hypothyroidism) and antithyroid drugs (carbimazole and propylthiouracil) used to treat an overactive thyroid (hyperthyroidism) do not suppress your immune system.
What was the effect of propylthiouracil on the normal rat BMR?
The effect of PTU injections on the normal rat was to decrease the BMR. The palpable goiter was due to the buildup of the precursors to thyroxine.
Why does propylthiouracil cause goiter?
Because the drug readily crosses placental membranes, propylthiouracil can cause fetal goiter and cretinism when administered to a pregnant woman (see Precautions, Pregnancy).
What are the adverse effects of PTU and methimazole?
Both methimazole and propylthiouracil can cause itching, rash, hives, joint pain and swelling, fever, changes in taste, nausea, and vomiting.
How long can I stay on carbimazole?
Therapy should be continued for at least six months and up to 18 months. Where a single dosage of less than 20 mg is recommended, it is intended that carbimazole 5 mg tablets should be taken.
Can hyperthyroidism be cured completely?

However, once your thyroid is removed or destroyed, you’ll need to take thyroid hormone replacement medications for the rest of your life.
Does carbimazole lower your immune system?
How does thionamide affect the immune system in AITD?
Thionamide drugs may directly influence the immune response in patients with AITD.185 This action may occur within the thyroid gland, where the drugs are concentrated. The action on the thyroid cells themselves decreases thyroid antigen expression and decreases prostaglandin and cytokine release from thyroid cells.
How is thionamide used for long term treatment?
When long-term thionamide treatment is planned, one of two treatment strategies is currently used: 1. Maintenance of euthyroidism with the minimum effective dose throughout the trial period, with thyroid function tests performed every 1 to 3 months.
How is thionamide used to treat Graves disease?
In summary, thionamide treatment of Graves’ disease thyrotoxicosis has the major advantages of not causing permanent hypothyroidism and of limiting exposure to radiation. It is, however, associated with a very high failure rate, and in many cases it is only a way to delay thyroid ablation by radioiodine or surgery.
How is thionamide metabolized in the body?
The thionamide drugs (carbimazole, its metabolite methimazole, and propylthiouracil) compete with Tg to act as substrates for iodination by TPO. Once iodinated, they are metabolized peripherally, depleting thyroid iodine stores.
