My cat's eye is watery from herpes. When will the discharge stop?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Female | spayed | 8 lbs

Ruby has conjunctivitis right now from a herpesvirus flare up. She went to the vet yesterday and does not have an ulcer. She is taking antibiotic eye drops and an oral anti inflammatory medication. She is showing improvement as her eye is being held open much better than yesterday but is still quite watery, which seems to be causing her the most discomfort. How long should it take for the eye to stop discharging so much? Thanks!

Poor girl. Typically I give these pets an anti-viral supplement (Lysine powder) since this is typically caused by a virus. You can give this long term also. The eye discomfort and secondary infection should be completely resolved within 7 days, with a drastic improvement of the eye seen in as little as 48-72 hrs. However since this is a virus and can't be completely resolved, the watery discharge can come back again and again as your pet goes in and out of latent periods. You can help limit these flare-ups by giving the Lysine powder I mentioned earlier on a consistent basis. I hope this helps!
