Aminophylline and theophylline are bronchodilators that relax the large air passages in the lungs and make breathing easier. Contact your veterinarian if your pet experiences an increased heart rate, vomiting, diarrhea, or seizures while being treated with aminophylline or theophylline.


Keep this and all other medications out of the reach of children and pets.
