Asthma / inhaler / sneezing

My cat has been using the inhaler for about a month. Things are going well but, seems he developed a problem. He seems to be sneezing and also has a runny nose and signs of an upper respiratory infection.  Swallowing a lot. Though it is not bad... now.. I worry that it can get worse with continued use.

Has anyone developed things like this? 

I have to believe it is related to the inhaler because he never gets things like this normally.

What asthma medication are you treating with?  I don't think an asthma medication would cause sneezing or a runny nose(at least my asthma meds have never had that effect)  I think a visit or at least a call to your vet is needed. Please let us know how he's doing. 

Flovent.

Another symptom today I don't know what to make of... throwing up fluid / foam.

I think you seriously want to get your cat in to see the vet--vomiting white foam can be a lot of things, including early kidney signs, but I am not able to diagnose, I just don't think that sounds like asthma and neither was the other symptoms.  Please let us know how he's doing. Sending positive healing vibes your way, asthma can be really scary, I have it and so does my son so I know.
