The Good- For many people, steroids break the misery of the prolonged migraine cycle. And, for some people, in addition to the pain relief, they feel energized and can accomplish some things they hadn’t been doing since the attack began.  Personally, whenever I am on a course of steroids, I find that I am extremely productive and energetic. I wish there wasn’t a significant downside to taking steroids as I truly feel great while taking them. The Bad- Steroids are not effective at breaking the migraine flare for everyone. So, if you are about to try this prescription, think positively and hopefully you will be in the group of people who find relief. Some people may have unpleasant but temporary side effects like trouble sleeping, moodiness, increased appetite and weight gain or a significant sense of agitation. These short term side effects subside when the steroid taper is over. If you have diabetes or pre-diabetes, remind your doctor as steroids usually increases blood sugar levels. It's temporary but it may be a concern. The Ugly – According to Dr. Alexander Mauskop, in one of his comments in his blog about steroids for migraine, “there is no safe dose of steroid.”  Some people have bad reactions from small amounts. There are significant and potentially dangerous side effects from steroids especially when taken frequently and/or long-term including glaucoma, diabetes and osteoporosis. A more in-depth discussion of the potential side effects is in this overview.  Anecdotally, of the 3 writers for Migraine Strong, one does well with steroids, one can have very small amounts and one cannot have any due to side effects.
