    About this product

    What is Proin ER?

    Proin ER is a safe and effective FDA-approved once-a-day tablet that controls urinary incontinence in dogs due to urethral sphincter hypotonus. It works by increasing urethral sphincter tone to help prevent urinary accidents. It's easy to administer. The liver-flavored tablets are given with food in a single dose per day. The patented release technology provides controlled release that ensures steady absorption. Proin ER provides the same proven efficacy as Proin in extended-release tablets. Proin ER requires a prescription from your veterinarian.

    Benefits:

    • Innovative - Patented release technology provides controlled release that ensures steady absorption

    How does Proin ER work?

    Proin ER works by increasing urethral sphincter muscle tone to help prevent urinary leakage.

    Cautions:

    Not for human use. Keep out of reach of children. Consult a physician in case of accidental ingestion by humans. Keep Proin ER in a secured location out of reach of dogs, cats, and other animals to prevent accidental ingestion or overdose. Proin ER may mask signs of incontinence due to urinary tract infection. Proin ER is not effective in dogs with incontinence due to neurologic disease or malformations. Proin ER may cause hypertension; therefore, use with caution in dogs with pre-existing heart disease, hypertension, liver disease, kidney insufficiency, diabetes, glaucoma, and conditions with a predilection for hypertension. Proin ER may cause increased thirst; therefore, provide dogs with ample fresh water. The safe use of Proin ER has not been evaluated in dogs that are intended for breeding, or that are pregnant or lactating.

    What is the most important thing I should know about Proin ER?

    Proin ER is indicated for the control of urinary incontinence due to urethral sphincter hypotonus in dogs. It requires a prescription from your veterinarian.

    How should Proin ER be given?

    Proin ER should be given once daily with food. Give Proin ER exactly as directed by your veterinarian. If you do not understand the directions, ask the pharmacist or veterinarian to explain them to you.

    What are the potential side effects of Proin ER?

    The most commonly reported side effects were vomiting, loss of appetite, diarrhea, excessive salivation, agitation, tiredness, vocalization, confusion, increased water consumption, weight loss, weakness, fever, panting, and reversible changes in skin color (flushing or bright pink). Abnormal gait, seizures or tremors, as well as liver enzyme elevations, kidney failure, blood in urine and urine retention have been reported. Contact your veterinarian if you notice restlessness, irritability, loss of appetite, the incontinence persists or worsens, or any other unusual signs.
