Hi Grace,   I'm not a doctor and I don't know anything specifically about Entocort. But, it seems a little odd that you've taken the med for a year and only just now are experiencing dizziness.   There can be a lot of causes of dizziness - are you well enough hydrated? Are you taking any other medications, either Rx or OTC, or vitamins that could be causing it. I get dizzy if I take too much of a Vit. B complex even though my doc says it's not possible.   I don't know what to tell you. In cases like this you may have to figure out which is worse, the D or the dizziness. And a 2nd opinion can't hurt anything either.   Let us know when you figure this out, it's curious.   Peace, Elizabeth
