Answer

Giving your cat a double dose of methimazole can be concerning, as this medication is essential for managing thyroid issues, and overdosing may lead to side effects. It's important to monitor her closely for any unusual symptoms.

  • Monitor for any signs of adverse reactions
  • Seek veterinary advice if symptoms arise
  • Ensure correct dosage in future administrations

Methimazole is used to treat hyperthyroidism in cats, and while missing doses can affect treatment efficacy, overdosing may result in side effects like vomiting, loss of appetite, or lethargy. It's crucial to observe your cat for any of these symptoms. If she seems unwell or shows any adverse reactions, contacting your veterinarian for guidance is advisable. They may recommend blood tests to check your cat’s thyroid levels and assess her overall health.
