Rated 5 out of 5 by 2 reviewers.
Rated 5 out of 5 by Works well for collapsing trachea This product, given together with hydrocodone, has been a miracle for our Pomeranian's severely collapsing trachea. The two medications together took him from a state of constant respiratory distress to a relatively normal life with low to moderate activity. The hydrocodone was only moderately effective, but when the Theophylline was added by our vet, the results were amazing. He weighs 12 pounds and takes 50mg twice a day. We had tried several other drug combinations and regimens before finally achieving the desired results with this one. 05/04/2016
Rated 5 out of 5 by Reduces our dog's wheezing and coughing related to his allergies. We have used Theophylline with our dog Zippy since we adopted him from a rescue organization in 2005. His allergy problems have been greatly reduced since we started giving him a 100mg tablet twice a day. 12/19/2014
