Whenever I have a sneezy kitty I always ask for extra medicine because it always seems to go through the house. Depending on your vet he/she may or may not give you more medicine. It really depends on your vets practices.

I hope poor sneezy boy Brodie feels better soon. I'm going through the same thing in my house right now.....sneezes, coughing and beleive it or not sore throats (it is really quiet because they really can not meow right now).
