However, Pred forte does have sulfites in it. I've read that the usual time of use is 10 days. I've been on it for 7 months with serious side effects. My eye pressure went up to 50 - dr. never checked my eye pressure. I had blurred vision for months, dilated pupils (which was wrongly diagnosed as Aidies Pupil), Very high blood pressure -180, 190 over 95 - that is now normal since I stopped using the Pred Forte. Also acne and excessive sweating - that has also gone away when I stopped this drug. I feel like I've been taking something very toxic. If it's not the sulfa, could it be simply the Pred Forte?
