My doctor gave me Theophylline for my cat, but after doing some research I am concerned. My doctor originally ordered Flovent inhaler, but the cost being close to $200 was very much of a burden, so my doctor recommended trying the Theophylline. Here is my concerns, first the capsules look big and I worry if they are too big. Second my research says cats are usually give 2mg per pound. My cat is 10 pounds and was ordered 75mg. Finally it says use caution in cats with kidney failure and old age. My cat is 16 with kidney failure. Does anyone else use the medication, how is your cat on it, if so. Thanks.
