Don't mess me about!

I have been far from well the last two weeks. I have had a recurrence of the throat/sinus/chest infection I had less than three months ago. As mentioned in previous post, we had to travel to Adelaide for an eye check up, on Monday just past, I had been ill since the previous Monday. I thought I was beating it, but it had other ideas. I attended out patients on Sunday evening, and was given a course of antibiotics. I finished those today, but still feel less than fit, and have a hacking cough. We went down town this morning, as hubby wanted to go to the council chambers for more info about solar power. He had seen the CEO on telly last night but had not managed to see all the news item.
We did that and I called into the clinic and managed to get an appointment this arvo, but not with my usual GP, as he is away. I had only consulted this fella once before, and was not all that enamoured.
I am allergic to a few drugs, one of which is a commonly prescribed one. Erythromycin, I had a bit of a 'set to' with this doctor about another matter, so the tone was set for him not to take heed of my concerns. He did not discuss his choice of medicine with me. I asked him what he was going to do for me and he said, rahter brusquely, he was giving me antibiotics. I inquired which one, and said not to give me Penicillin, or it's derivitives. He said it was not that but was from the same family of drugs as Erythromycin. I expressed my concern and he assured me it was more than likely OK for me.
I was stunned to discover the script was $24.90 and for only THREE tablets
I very seldom read the information leaflet in drugs boxes. For some reason I did this time. Thank God I did, as it clearly stated, if the patient was allergic to Erythromicin, NOT to take this medication.I rang the chemist and he said I only had two choices. If I decided not to take it, he would take it back. I then rang my daughter and she very firmly told me not to take it, and to ring the doctor and ask for a different script. I have never had to do that before and was aprehensive about it. I did ring, and the receptionist took my number and got him to ring back. I told him what was in the leaflet, and that I had a very bad feeling about taking it. I also told him I had finished up in hospital the last time I had the Erythromicin, and would he write me a script for the Cefalexin my Dr. had given me. He acquiessed very readily. I was extemely relieved I had not had to 'get tough' with him.
