My cat's ear drops are working. Should I finish the full course?

Updated on September 23rd, 2025

Pet's info: Cat | Domestic Shorthair | Female | spayed | 2 years and 9 months old | 9.3 lbs

My cat recently went to the cat for some ear issues and was given tresaderm to use twice a day for 7 days. She has had 2 doses of the drops and has since stopped scratching at her ear and tilting it to the side. Should I discontinue the drops or continue for the full week?

You should continue for the full week. When you stop treatment early, you are leaving behind organisms who are more resistant to the treatment. They will be the organisms who breed the next generation and it may have the resistance as well. Always finish the full course of any treatment to try to eliminate this scenario. I'm glad Luna is feeling better and please feel free to post any additional questions.
