How does phenylpropanolamine work in dogs? In veterinary medicine, phenylpropanolamine is used almost exclusively for the control of urinary incontinence in dogs and occasionally in cats. Phenylpropanolamine is able to increase sphincter tone in the urethra thus curtailing inadvertent urine leakage.
Why phenylpropanolamine is banned? Phenylpropanolamine has been taken off the market in the United States because of the increased risk of hemorrhagic stroke in women associated with its use as an appetite suppressant.
Are there any side effects to Proin for dogs? Common side effects of Proin in dogs include diarrhea, vomiting, loss of appetite, weight loss, irritability, restlessness, agitation, vocalization, difficulty urinating, increased thirst (polydipsia), increased water intake, and lethargy.
How long can a dog stay on Proin? A study has shown that Proin is safe and effective for dogs for at least a 28-day period. Throughout the clinical study, Proin was demonstrated to be effective in controlling leakage based on the significant reduction of urinary accidents per week.
