I have been suffering with light-headedness for 3 1/2 years and I have always been convinced that the Prednisolone is causing it. Last Thursday I forgot to take my medication and I was free of the light-headedness. I just couldn't believe the difference. I felt wonderful. I normally take the Pred first thing in the morning about 8 o'clock and within 1 hr the light-headedness would begin and last for the remainder of the day. However, after missing the dose on Thursday I did an experiment and took Friday's dose late afternoon. The light-headedness returned but not so bad, and I did not have to suffer for the whole day. Can anyone tell me if there is any reason why I could not take the Prednisolne in the afternoon rather than in the morning. At present I am on 9 mg and will reduce to 8 mg in a couple of weeks. I have GCA and PMR but at present free of pain and GCA symptoms.
