Does methimazole affect thyroid hormones?
Methimazole prevents iodine and peroxidase from their normal interactions with thyroglobulin to form T4 and T3. This action decreases thyroid hormone production. Methimazole also interferes with the conversion of T4 to T3. Since T3 is more potent than T4, this also reduces the activity of thyroid hormones.
Does Methimazole increase warfarin?
Methimazole may increase the activity of warfarin by further reducing the activity of vitamin K in the body. Hyperthyroidism increases elimination of beta blockers. Correcting hyperthyroidism will cause less elimination of beta blockers. Therefore, the dose of beta blockers may require reduction when hyperthyroidism is corrected.

What is beta blocker used for?
This the name for a class of medications used to treat high blood pressure which can be used as an adjunctive therapy for the symptoms of hyperthyroidism. They are used in addition to the other treatments for hyperthyroidism. In addition to lowering blood pressure, beta blocker medications serendipitously happen to reduce the conversion of T4 to T3 in the peripheral tissues such as the heart, thereby reducing the negative effects of high thyroid levels. These medication also reduce the elevated heart rates that can be caused by high levels of thyroid hormone. The side effects of these medications include lowering blood pressure or heart rate too much, so your physician will need to adjust the doses accordingly.

Surgery would be the quickest management of hyperthyroidism due to toxic multinodular goiter, Graves disease, or toxic hot nodule.

What Are the Different Kinds of Antithyroid Medications?
There are two conventional medication options for hyperthyroidism, which are:
Antithyroid Drug Side Effects
There are many possible side effects with antithyroid medications, but they are typically manageable and low risk.
Are Antithyroid Medications Safe?
When taking any medication, it’s important to be mindful of potential side effects, but there usually isn’t cause for alarm. Research shows that antithyroid medication is generally safe and effective for symptom relief, even with long term use.
Improving Gut Health for Better Thyroid Function
We know that gut health is intricately linked to the outcome of any autoimmune condition, and this includes thyroid conditions like Hashimoto’s disease and Graves’ disease.
Antithyroid Medication Alternatives and Complementary Treatments
Although antithyroid medications are generally safe and have a low risk of severe side effects, there are natural remedies that may be able to either replace or complement antithyroid drug therapy for the treatment of Graves’ disease or hyperthyroidism.
What is Graves disease?
Graves’ disease is an autoimmune condition caused by thyrotropin (thyroid stimulating hormone [TSH]) receptor stimulation via TSH receptor antibodies (TRAb) with a lifetime incidence rate of 0.5–3% . The majority of patients with Graves’ hyperthyroidism have a prolonged course characterized by episodes of remission and relapse for many years [ 1 ]. There are three forms of therapeutic approaches, namely, antithyroid drugs (ATDs), radioiodine (RAI) and surgery, but none are able to cure the disease in all patients [ 2 ]. In recent years, ATDs and in particular methimazole (MMI) or carbimazole, have become the first treatment of choice for Graves’ disease [ 3, 4 ]; however, relapse of hyperthyroidism occurs in almost half of the patients after withdrawal of the conventional 12–18 month ATD therapy [ 5 ]. Two systematic reviews/meta-analyses have shown that long-term continuous MMI is an effective and safe therapeutic mode for durable euthyroidism in Graves’ hyperthyroidism [ 6, 7 ]; in addition, the majority of such patients enter remission following discontinuation of long-term ATD treatment [ 8, 9 ].
How long did Graves disease last?
An 80-year-old Iranian woman with Graves’ disease was treated with MMI for 31 years. While receiving treatment, she always had a normal serum TRAb concentration; however, three times during the 31 years she decided to stop MMI therapy, and each time the disease recurred 16–21 months after MMI withdrawal. It is noteworthy that she maintained euthyroidism with the low-dose 1.25–2.5 mg MMI daily without any adverse events during three decades of treatment.
Is Methimazole a good treatment for Graves disease?
Methimazole (MMI) is the treatment of choice for patients with Graves’ disease. The major drawback of this treatment is the relapse of hyperthyroidism in half of the patients after discontinuation of the recommended conventional 12–18 months of MMI treatment. TSH receptor antibody (TRAb) concentration is recognized as the strongest predictor of hyperthyroidism relapse. In this case report, efficacy of low-dose MMI to control hyperthyroidism even after multiple recurrences in the setting of normal TRAb concentrations is shown.
