Summary

  • Carbimazole is used to treat hyperthyroidism, which is a condition where the thyroid gland is overactive and produces too much thyroid hormone. This can lead to symptoms like rapid heartbeat, weight loss, and anxiety.

  • Carbimazole works by reducing the production of thyroid hormones in the thyroid gland, which is an organ in the neck that regulates metabolism. It inhibits an enzyme called thyroid peroxidase, which is responsible for hormone production.

  • The usual starting dose for adults is 15-40 mg daily, divided into two or three doses. The maximum recommended dose is 60 mg per day. It is taken orally, which means by mouth, and should be swallowed whole.

  • Common side effects of Carbimazole include nausea, headache, and joint pain. These effects are usually mild and temporary. If you experience severe symptoms, contact your doctor.

  • Carbimazole can cause a decrease in white blood cells, which are cells that help fight infections. It is contraindicated in patients with a history of agranulocytosis, which is a severe drop in white blood cells, and in pregnant women due to potential harm to the baby.
