Living with Sickle Cell Taking Nicosan and Hydroxyurea By Sickle Cell Warrior - September 16, 2009 0 13 Share Facebook Twitter Google+ Pinterest WhatsApp I got a question today that I couldn’t answer. Has anyone taken Nicosan WITH Hydroxyurea? Did you notice a difference? Have you had any side effects? Please share your story, either via comments or through my email. Thanks!
