Proin Chewable Tablets

This prescription item can not be shipped to Arkansas, Illinois, Iowa, Louisiana, North Carolina, Oregon or West Virginia.

(Phenylpropanolamine HCl)


Proin is a medication developed to manage urinary incontinence in dogs. Urinary incontinence, or uncontrolled leaking of urine is most frequently seen in spayed female dogs or dogs with obesity. Although less common, male dogs may also experience urinary incontinence. Proin chewable tabs are administered either as a treat or given with food.


Item Specifications:


For Use:




Use as Directed by your Veterinarian


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.



Store at Controlled Room Temperature.


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. May cause excitability and restlessness.



Tell your veterinarian if your pet has ever had an allergic reaction to this medication. Tell your veterinarian if your pet has glaucoma, hyperthyroid disease, diabetes, heart problems or high blood pressure. Tell your veterinarian if your pet is pregnant or lactating.


Side Effects:

Stop giving Proin and contact your veterinarian immediately if your pet has an allergic reaction (difficulty breathing; swelling of the lips, tongue, face; and hives). Other side effects that may occur include restlessness, irritability, increased heart rate, increased blood pressure and loss of appetite. Continue to give the medication and contact your veterinarian. Other less serious side effects may occur. Contact your veterinarian about any side effects that seem bothersome.


Seek emergency veterinary medical treatment. Symptoms of overdose may include increased blood pressure, increased heart rate, seizures or coma.


Federal law restricts this drug to use by or on the order of a licensed veterinarian.

Robert K on Feb 12, 2019
Dr. prescribed for incontinence issues. Since Daisy has been on this, the problem has subsided. Her personality has changed. She is more affectionate and sure of herself as she no longer feels we are upset with her even though we never yelled at her concerning her medical issue. We recommended this to a friend whose dog had the same problem and the results are equally as positive.
