Is lysine safe for cats on meds, kidney diet, and appetite stimulants?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Shorthair | Male | neutered | 18 years and 10 months old | 9.5 lbs

Can tony take a lysine supplement with his other meds:amlodipine besylate, methimazole, tumil K potassium supplement and mirtazapine appetite stimulant? He also eats a kidney diet and I wonder if the powder lysine supplement may flavor the food and make him like it better? Thanks!!

I would recommend checking with his vet for confirmation that he needs the lysine supplement at all. However, I'm not aware of any drug interactions. There are lysine treats that he might like, I'm not sure what the powder tastes like.
