Viagra...Cialis...

Okay...so I am a new nurse. There was this little old lady at my LTC facility that I work at how recently has a heart attack a few months back. I know that viagra was originally a cardiac drug....but I was wondering why on earth would a doctor prescribe both viagra and cialis at the same time for her heart issues?! Does this seem odd to you as well? Or just something you've seen here and there...

Or is it just me...thinking it's weird...that viagra or cialis drugs I always have viewed as something men take for um yeah..those special times....

What is your input? I'm just curious...even the RCM her eyes were bugging out as she saw that on the MAR and she was all wipping out the med book checking it out...yeah
