Is it Haram to take my medicine while fasting?

I have to take two medications twice a day. One I was going to try to take during suhoor, but the other medication is a stimulant and if I take it too late or early I will not longer be able to sleep. I am supposed to take it at noon. I don’t want to miss out on Ramadan but I have pots now pots now, and if I miss these medications I will only be able to lie in bed all day.
