Can I give my cat methimazole twice in one day if I forgot yesterday's thyroid dose?

I completely forgot to give my cat her methimazole dose for her thyroid yesterday, and now I'm wondering if it's safe to give her two doses today to make up for it. I know consistency is important, but I'm worried about giving too much at once. Should I stick to the regular dose today, or is it okay to give her an extra one to cover the missed dose?

Answer

It’s important to give your cat her methimazole dose consistently, but giving a double dose can be risky. Let's explore the right approach to handling a missed dose.

  • Stick to her regular dose today.
  • Avoid doubling up on doses.
  • Maintain a regular dosing schedule moving forward.

When a dose of methimazole is missed, it's generally best to skip the missed dose and continue with the regular dosing schedule. Giving two doses within a short period can increase the risk of side effects like gastrointestinal upset or more serious conditions. Prioritize keeping a consistent schedule and consult with your veterinarian if any concerns arise.
