What is Proin?

How it works:
Proin contains the active ingredient phenylpropanolamine, an adrenergic agent that works by tightening the bladder sphincter muscle, which helps to control urine leakage.

Cautions:
Don't give Proin with ephedrine or epinephrine, and don't give it within two weeks of using a MAOi, such as Anipryl, selegiline or a Preventic Collar. Possible side effects can occur, including restlessness, or loss of appetite, difficulty breathing, hives, and swelling of the lips, tongue, or face. If these or any other side effects occur, contact your veterinarian immediately. We do not ship Proin to Arkansas, Iowa, Louisiana and Oregon where it is classified as a controlled substance.
