Immediately after adding diluent, the product should be
shaken well for a period of 2 to 3 minutes to aid dissolution.NOTE: Because PANHEMATIN contains no preservative
and because PANHEMATIN undergoes rapid chemical
decomposition in solution, it should not be reconstituted
until immediately before use. After the first withdrawal
from the vial, any solution remaining must be discarded.
No drug or chemical agent should be added to a PANHEMATIN
fluid admixture unless its effect on the chemical and physical
stability has first been determined.HOW SUPPLIED
