 IV or IM ?
i think it`s because of their Formulation \
-some drugs needs Preservatives which may lead to emboly,toxicity if administrated IV -
-and the Solvents;IM drugs often have been solved in a unsoluble base.and if we insert them directly into the veins,, :roll:
-IV dose is often less than IM formulation
usually using IM instead of IV is more Dangerous!
