Ruth and Ben’s discussion

Ruth talks with Ben.

Pharmacist: Now that we have some privacy, lets talk a little more about why you’ve come here today.

Ben: I hadn’t had intercourse since my wife died but I’ve tried a few times recently with my new partner and it’s just not happening.

Ruth: I can understand that must be frustrating

Ben: Yes… I thought all my problems were over when they fixed my heart.

Ruth: You mentioned at the start of our conversation that you had stopped taking your medications is that the reason?

Ben: I suppose I had two reasons, the first was I felt so well after my operation a year ago that I felt I didn’t need them and secondly I was worried if I started them again it might make my problem worse.

Ruth: OK let’s see if I fully understand what’s going on. You had your PCI done a year ago and felt really well after it so stopped your medications as you didn’t feel they were necessary. You then entered into a new relationship and you noticed you were having a problem with impotence and were scared restarting the medications may make things worse.

Ben: Yes that about sums it up.

Ruth: As I explained earlier I can’t offer you viagra as you require a prescription for it. My advice would be to make an appointment with your GP to discuss the impotence and the issues you are having with your medication. How does that sound to you?

Ben: Thank you for listening I will go to the GP and now I’ve talked about it once I will hopefully find it easier to speak to the GP.
