My husband took Malaria prophylaxis prior to a deployment to South America
and the Carribean several years ago.  He states he received 3 or 4 doses of
the medication during the 6 months and he was not allowed to donate blood
for a long time (he thinks it
was several years) after returning.  If the medication is OK to take while
nursing or pregnant and for toddlers to take (as Katherine Dettwyler
suggested), does anyone know why you would not be able to donate blood?

Just curious,
