Rx Methimazole 5mg x 1 tablet
Methimazole is a prescription antithyroid medication formulated for cats to help control hyperthyroidism, a condition often seen in middle-aged to older felines. This condition is caused by an overproduction of thyroid hormones (T3 and T4), leading to an increased metabolic rate. Methimazole works by inhibiting the synthesis of these hormones, helping to restore and maintain a healthy metabolic balance.
