Explanation
•Propylthiouracil is used to treat hyperthyroidism. The most serious adverse reaction is agranulocytosis, or a reduction in granulocytes (Neutrophils, basophils, eosinophils). This most commonly occurs during the first three months of therapy.
•Seizures, hyperkalemia, and hypokalemia are not associated with the use of propylthiouracil.
