I started methylprednisolone yesterday and i have palpitations i had 3 pills yesterday and 3 today but with the first one my heart pulse fast?

Yep. It's a Soup: What I meant to say, "It's a Side Effect..." But doesn't "It's a Soup!" ..... said in the Old World Syle of Momma Making Soup in the kitchen.....sound so much nicer? But of course, your tachycardia may not feel very nice and may not be good for you either.....unlike Momma's soup. So best, call the Doktor and tell them you've got this adverse effect. Perhaps a slightly lower dose is in order

Can happen: Best to stop the med and notify your doctor of the side effect. It is a common side effect of this medication. Palpitations should resolve in 24 -48hrs. If they do not, see doctor. Hope this helps. Best of luck. Dr R

First pill only: People react very differently to steroids. If strange sensation was only associated with the first pill there is no reason to be concerned.
