Prednisolone was prescribed for my cat twice in six months, is this ok?

My cat has asthma and was prescribed Prednisolone for a week a few months ago. Now he has asthma flare up, so it was prescribed to him again for five days.

I read that excessive use of steroids is not good for cats. Should I give it to my cat or see another vet?

The dose both times is 0.5 ml twice a day
