Hi, I originally attended my GP for erectile dysfunction; no real solution , he tried very low dosage of 10 mg cialis foe a period of two weeks. No joy bug I asked tk be referred to Hospital, tried cialis. 10 mg daily for about 3 months ,worked reasonably, tried silendfil 50 mg and between the cialis regularly and sildenfil on a rare occasion when I was tired, it seemed to work, I have now been signed off the hospital and must return to the GP. That will mean. Private prescription as before or will the hospital now record at i need the medication , the cost then becomes preventative as private prescriptions in Northern Ireland cost a bomb, pardon the pun
