My nuro told me up to 1100mg/day for a short while was considered SAFE as long as you up in small increments and same goes for weaning off, but you should take some kind of a strong ANTIACID for stomach upset, I'm taking Pantoloc 40mg twice daily one in the morning and evening and works great.

Now for Pred the highest of been is 60mg/day make sure to take 1st in the morning as early as possible if you take them to late in the day you'll have a hard time getting to sleep! The other the sooner you can get off them the better, and don't wean off more than 10% off the daily taken dose every 2nd week...I'm down to 4mg/day and finding it tough!!! My Doc had told me that once you get under the 5mg dose it would get tougher until my adredeline gland picks up the slack...I feel like I'm running out of gas at times! since I've been on the lower dose but takes a couple a days to adjust to the new dose.
