Can anyone help me please. Can Picolax take more than a few hours to work? I have a colonoscopy procedure tomorrow and have been given two sachets of Picolax to take to 'flush' me out, so to speak. I took one at 17.30 tonight and had a very small bowel movement two hours later. Well over three hours have passed now and nothing else has happened. I have to take another sachet at 05.00 in the morning and I'm hoping this will do the trick. I have been fairly constipated over the last eight days so I can only think this is why it's taking a while to work properly.
Thanks in advance
