Hi,
i would either ring your g.p to make an appt or go to a & e.
as far as i remember i think that naproxen is related to the asprin family.
hope that what i know about this helps you out.
Naproxen is a prescribed NSAID, or heavy duty Aleve. It has blood thinning side effects which could be the source of your bleeding. If the bleeding is even moderate, I suggest you discontinue use and immediately scheudle a follow up appointment with your provider. If bleeding is very mild, such as you simply bleed more if you cut yourself, i would take note and mention upon your next appointment. If you are actively bleeding, of course call 911 or go to the ER immediately
What do you mean you're bleeding? From where? You need to ask a specific question in order to get an answer.
