Proin contains the active ingredient phenylpropanolamine, an adrenergic agent that works by tightening the bladder sphincter muscle, which helps to control urine leakage.
PROIN is indicated for the control of urinary incontinence due to urethral sphincter hypotonus in dogs.

If these or any other side effects occur, contact your veterinarian immediately
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.
PROIN may cause increased thirst; therefore, provide ample fresh water.
Overdose has been associated with dogs chewing through closed bottles of PROIN and consuming multiple tablets. Therefore, it is important to store PROIN Chewable Tablets out of reach of dogs and other pets in a secured location.
Use in dogs with incontinence due to a urinary tract infection will mask symptoms. PROIN is not effective in dogs with incontinence due to neurologic disease or malformations.
PROIN 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. Use with caution in dogs receiving sympathomimetic drugs, tricyclic antidepressants, or monoamine oxidase inhibitors as increased toxicity may result. Use with caution in dogs administered halogenated gaseous anesthetics as this may increase the risk of cardiac arrhythmias.
A laboratory study on human blood revealed that PPA used in conjunction with aspirin may potentiate decreased platelet aggregation.
The safe use of PROIN in dogs used for breeding purposes, during pregnancy or in lactating bitches, has not been evaluated.
Store at controlled room temperature 20-25°C (68-77°F), excursions permitted between 15-40°C (59-104°F)
Proin is easy to administer on your pet’s food or as a treat. Your veterinarian will choose the formulation best suited to the needs of your dog.
Often the dosage can be gradually reduced after the dog is
stabilized. However, this condition is not curable and the need for
ongoing treatment is likely.
