The most serious side effect of methimazole is agranulocytosis, a condition where the white blood cell count drops significantly, leading to a weakened immune system and increased risk of infections. This side effect is rare but requires immediate medical attention if symptoms such as fever, sore throat, or other signs of infection occur. Regular monitoring of blood cell counts is recommended for patients on methimazole to detect this condition early.
