I am a 47 year old male Liver Transplant recipient, doing very well, 3 years Post Transplant. I was given Norvasc (Amlodopine) following Transplant because of blood pressure issues Post Transplant. The Doctors say it is common to have elevated Blood Pressures after Transplant while taking Tacrolimus (Prograf). I ran out of Norvasc and had issues getting it filled for about 10 days, when I filled it and started taking again I notice I am extremely fatigued, sleepy and having problems staying awake. Over teh past 2 months I have been doing very well and not had any issues at all. Is it possible the Nirvasc is causing me to be tired and sleepy?
