Proin® is given to pets that have trouble with urinary incontinence. This problem is most common in older spayed females, but often happens in males as well. Urinary incontinence is uncommon in cats, but may be treated with Proin® if found. In some cases of urinary incontinence, Proin® may be used in conjunction with an estrogen, Diethylstilbestrol.
How It Works
Phenylpropanolamine works releasing norepinephrine, which stimulate the alpha-adrenergic and beta-adrenergic receptors. One of the many organs these receptors effect are the sphincter mucles. The sphincter muscles are those that surround the urethra (where urine flows from the bladder on out), allowing it to open or close. Proin® strengthens these muscles making the urethra tighter, preventing your pet from subconsciously urinating.
Proin® is typically given 2-3 times a day. It will take several days of taking this drug before results are seen.
Store in a tightly sealed container at room temperature.
Give the dose as soon as possible. If it is almost time for the next dose, skip the missed dose, and continue with the regular schedule. Do not give your pet two doses at once.
