You must wait at least eight weeks (56 days) between donations of whole blood and 16 weeks (112 days) between double red cell donations. Platelet apheresis donors may give every 7 days up to 24 times per year. Regulations are different for those giving blood for themselves (autologous donors).
Giving Blood, under normal rules, will not decrease your strength. Whole Blood can be donated as often as every 56 days, plasma, no more frequently than every 48 hours, and platelets, a maximum of 24 times a year.
