My 5 year old son takes a few medications Clydamycin, Vyvanse, Singulair, and Zyrtec. The problem im having is every since he started taking the Clydamycin he has been having nose bleeds (epistaxis), some last for a few minutes others last for 15 to 20 minutes. I m not sure what to do if anything and how we can get them under control, do you have any advice?
