Does anyone have any experiences with Resolor ( Prucalopride) that they could share with me? I have just been prescribed these for chronic constipation which I've had since birth. I took one 2mg tablet yesterday and within 1 hour they had the desired effect and I had a comfortable bowel movement but unfortunately I also had a horrific headache which felt as though my head was in a vice and I still have the headache over 24 hours after taking the tablet. As wel as the vice type gripp on my head I have pain running up through my shoulders and neck. I didn't get much sleep last night and I feel dithery and really quite ill. I have checked the side effects list and know headaches is the first one listed but I can't work out if all my symptoms are due to the tablet or if I'm mysteriously 'going down' with something else at the same time- I know I cannot take any more 2mg tablets as I cannot get through a working day feeling like this, I haven't left my bed for over 18 hours, but I'm considering cutting the tablets in half to try taking just 1mg next time. Any experiences and thoughts on this would be gratefully received.
