I was told to discontinue clonidine by my GP. I had been taking it for about five or six weeks. After 48 hours, I had a headache and then my vision became blurred and my B/P shot up.
I ended up in A/E and the doctor there was under the impression it was withdrawal from clonodine after he eliminated all else. The experience was terrible and I felt someone had been kicking my head about the street like a football. The following day I felt better but the tremulous feeling in my body remained for another six hours.
