My cat's on methimazole and he's stopped eating, should I be concerned?

My cat has been on methimazole for his thyroid condition, and I've noticed he hasn't been eating much, if at all, over the past couple of days. I'm really worried because he's usually such an enthusiastic eater. Could this be a side effect of the medication, or is there something more serious going on that I should know about?

Answer

Your cat's reduced appetite could be a side effect of methimazole, or it might indicate a more serious underlying issue requiring attention.

  • Reduced appetite is a known side effect of methimazole.
  • Monitor your cat for any additional symptoms or changes.
  • Consulting a veterinarian can provide clarity and peace of mind.

Methimazole, a medication for hyperthyroidism, can have side effects, including a decrease in appetite. However, since your cat's eating behavior has significantly changed, it's important to monitor him closely for other symptoms. Changes in behavior, weight loss, or vomiting need careful attention. A vet can help determine if these changes are a medication side effect or a sign of a more serious condition. Your concern is valid, and seeking professional advice is a great next step.
