About this medicine

Phenylpropanolamine treats urinary incontinence.

Products with this ingredient include Proin. The FDA hides brand names in its public data, so these reports cover every product with the same active ingredients.

Questions owners ask

Can Phenylpropanolamine cause high blood pressure in dogs?
44 reports link the two, but a report alone does not prove the medicine was the cause: other illnesses, other medicines or coincidence can be involved. Your vet can judge it for your animal.
How soon after a dose was it reported?
In half of the reports with dates, it started within the same day of the first dose.
What should I do?
Don't give another dose until you've spoken to your vet, and keep the packaging so you can tell them the product and dose. Your vet can also report it to the FDA (or you can, through the manufacturer or FDA form 1932a).
