Eng., Dried Antitetanic Serum. Synonyms, Dried Tetanus Antitoxin, etc. Obtained by the evaporation of either of the two other antitetanic serums.

Average Dose

Hypodermic, 10,000 units; protective, 1500 units.

The curative value of Antitetanic Serum is seriously questioned, but its protective value is beyond dispute. It is the custom to give 1500 units as the protective dose for patients of almost any size or age.

The sooner the injection is made after injury the better the protection seems to be. For site of injection, serum sickness and its treatment, see Serum Antidiphthericum.
