Side effects of Phenylpropanolamine?

Phenylpropanolamine treats canine urinary incontinence. The dog medicine works by tightening bladder muscles. The prescription medication must be prescribed by your vet because there are contraindications and side effects.

Contraindications for Phenylpropanolamine

Never give your pet phenylpropanolamine if he is using ephedrine, epinephrine or an MAOI. It's important for a dog to be off of MAOI dog medicines for a full two weeks before starting phenylpropanolamine. Dangerous reactions can occur if the medications are used together.

If your pet is on NSAID drugs, your dog's blood pressure may increase. When used with digoxin, irregular heart rhythms can occur.
