How It Works
Methimez works by inhibiting thyroid peroxidase, an enzyme essential for thyroid hormone synthesis. This blocks the formation of thyroid hormones (T3 and T4) in the thyroid gland, gradually reducing circulating hormone levels and alleviating hyperthyroid symptoms.
Dosage
Patient Category | Initial Dosage | Maintenance Dosage |
---|---|---|
Adults | 1-2 tablets 3× daily | 1-2 tablets daily |
Children | As prescribed by doctor | Adjusted based on response |
Take Methimez with or without food at the same time each day. Divide doses evenly throughout the day for optimal control.
Duration of Action
Methimez begins working within hours but clinical improvement typically occurs within 2-4 weeks. Maximum therapeutic effects are usually seen after 6-8 weeks of consistent use. The medication has a half-life of 4-6 hours, requiring multiple daily doses for sustained effect.
Side Effects
Common side effects include skin rash, itching, headache, and mild gastrointestinal upset. Some patients experience joint pain, muscle aches, or temporary hair loss. Serious but rare side effects include severe liver problems, low white blood cell count, or agranulocytosis requiring immediate medical attention.
Warning
Methimez can cause serious liver damage and life-threatening blood disorders. Regular blood tests are essential to monitor liver function and blood cell counts. Discontinue immediately and seek medical attention for signs of infection, unusual bleeding, severe fatigue, or jaundice. Not suitable for treating thyroid storm emergencies.
Pregnancy and Breastfeeding
Methimez crosses the placenta and can affect fetal thyroid development. Use during pregnancy only when benefits clearly outweigh risks to the fetus. The medication passes into breast milk in small amounts. Breastfeeding mothers should be monitored closely along with their infants.
Interaction
- May enhance effects of anticoagulants like warfarin
- Possible interaction with beta-blockers affecting heart rate
- May alter effectiveness of certain diabetes medications
- Potential interaction with digoxin requiring dose adjustments
- Could affect response to certain vaccines
- May interact with theophylline, requiring monitoring
Precaution
Regular monitoring of liver function and blood counts is essential during treatment. Use cautiously in patients with liver disease or blood disorders. Inform all healthcare providers about Methimez use before any medical procedures. Avoid in patients with previous severe reactions to antithyroid medications.
Important Information
Methimez requires regular medical supervision and laboratory monitoring. Do not stop taking suddenly without medical advice as this can worsen hyperthyroidism. Store at room temperature away from moisture and heat. Carry identification indicating thyroid medication use. Report any signs of infection, unusual bleeding, or severe fatigue immediately to your healthcare provider.
