changed bimix prescription?

I have been using a bimix prescription for several years now (Bimix #1 Pap 30 - Phent 1). My prescription recently expired, and the doctor required a visit to renew it. I went for the visit, got the new order, and faxed it to my pharmacist, who called me to say the doctor changed the prescription to Pap 30 - Phent 0.5.

I assume this is a weaker prescription?? The doctor didn't say anything about changing the prescription, and now, of course, he's gone until Tuesday. Very frustrating, given it takes the pharmacy a few days to make the prescription, and I am completely out.

I cannot think of why he would have changed the prescription, except I did tell him I was using daily Cialis... but I am only trying that and not sure that I will continue. Could that be the reason? Even still, it seems he should have said *something* about changing the prescription...? Unless it is a mistake.

I did

The prior prescription was Pap 30 Phent 1

The new prescription is Pat 30 Phent 0.5

Your doctor forbids pills and shots the same day, including for low doses like daily Cialis?
