Hi Doctor, I was born with sickle cell anemia. growing up I would get frequent pain crisis. However, as I made the needed lifestyle changes - drinking lots of water, not getting too fatigued in exercise. etc... I also, take fansidar, an anti malaria medicine. I notice that if it take a full dose for an adult every 6 weeks, I feel a lot stronger carrying out my day-to-day activities. My question is: Is it safe taking this drug as frequently as I do. I ve been taking it for over 10 years now. Thanks in advance...
