Richard Perry is a 64-year-old patient who has been successfully treated for HTN for over 15 years with propranolol (Inderal). Mr. Perry is allergic to cats. However, he recently visited his grandson who has a new kitten. He now has weepy eyes and a running nose. He is considering taking the OTC medication pseudoephedrine (Sudafed) to relieve the allergic symptoms.

1. Is it safe for Mr. Perry to take this OTC medication? Why or why not?

2. Is there another OTC medication that would be safer for this patient?
