I took a claritin (loratadine) and klonopin before laying down in bed and my nose just started bleeding. is that normal or should i be worried. 1st time in a while?

Drying effect?: Claritin (loratadine) may have some drying effect on the mucous membrane and thus this may lead to a nosebleed especially when the environment is dry or breezy. On the other, this may just be a coincidence. Suggest you try Allegra to see if this too would cause a nosebleed. If the problem persists, consult your doctor since sometimes just a simple cauterization may top the bleed forever.
