Clavamox is a semi-synthetic penicillin (amoxicillin). It is commonly used
in both dogs and cats to treat skin and soft tissue infections such as
wounds, abscesses, periodontal infections, and cellulitis. Some of the side
effects are gastro-intestinal upset (diarrhea, vomit, or loss of
appetite)... There are other alternatives to Clavamox however; they can be
far more expensive and not nearly as effective as Clavamox. Your vet, not
knowing if your cat has asthma or a respiratory/ sinus/bronchial infection
has decided to have you try Clavamox because it treats soft tissue
infections. Your vet probably has already set a plan to start a diagnostic
process and, to work towards a definite diagnosis. It may take several
efforts to find the right direction to go in (prescription wise) because
each animal is different. My suggestion is for you to administer the
recommended dosage of Clavamox to your cat regardless of if you think it
needs it or not. To the point, I don't think I have ever heard of any
specific side effects, other than the few I listed above. I hope that
somewhat answers your question.

Clavamox is an antiobiotic, and AFAIK, antibiotics shouldn't be used
indefinitely. Yes, you should definitely question your vet. I had a horrible
vet once, and it took way too long for me to figure it out. I failed to
question him *enough*.

Angela,

    You need to see if you cat is tolerable to Clavamox before you decide
to not administer the medication. Traditionally, a large percentage of cats
and dogs are intolerable of taking Clavamox, however your cat may be the
exception. You need to understand why the vet prescribed Clavamox in the
first place. The vet (He or she) is trying to single out what is ailing your
cat. This is the first step in figuring out if it has a respatory infection
or something more serious that Clavamox cannot correct. If your cat is
intolerable of taking Clavamox, then you will know by discharge. Like I
said, predominately there are a large number of animals that are intolerable
of Clavamox, but you maybe you have a cat that is the exception.

I would say first off that if you are questioning you vet already that
you should get a second opion.  Did you bring these concerns up with
the vet??  If not you should.  Remember that she / he has had a lot
more training then you have caring for pets.

Perhaps he meant use the entire bottle of clavamox. I don't think anyone would
prescribe using it forever. It wouldn't help after a while and will kill all
the good bacteria in her system which she needs to digest food. Ask him what he
meant again.

Indefinitely probably doesn't mean forever.  I have a cat taking clavamox
indefinitely.  If the cat has an infection, yes he/she does need
medication.  If you really want to question the vet's decision (but I
wouldn't) I'd go to another vet, but don't take him off the medication on
your own.
