Post Donation Advice Drink lots of fluids for next 24 hours Avoid smoking for one hour & alcohol till after a meal Dont use elevator to go up immediately after donation as it will make blood rush to your feet & make you dizzy! Avoid highly strenuous exercises & games for a day If you feel dizzy, lie down & put your feet up. You will be alright in 10-20 mins. Remove band-aid after 4 hours. If it bleeds, apply pressure & reapply band-aid. If bruised and painful, apply cold-pack 4 to 5 times for 5 mins each. The bruise is due to blood seeping into the surrounding tissue. It will take a few days to get reabsorbed.
