Ergocalciferol (Deltalin®, Eli Lilly and Company) is a form of Vitamin D, also called vitamin D2. It has the systematic name "(3β,5Z,7E,22E)-9,10-secoergosta-5,7,10(19),22-tetraen-3-ol". It is created from viosterol, which in turn is created when ultraviolet light activates ergosterol.

Ergocalciferol Tablets BP 0.25mg , SPC from the eMC (625 words)
Ergocalciferol appears to take slightly longer to act and slightly longer to cease acting than dihydrotachysterol, therefore it is even more important to avoid ergocalciferol overdosage than it is with the latter.
Ergocalciferol is inactivated, probably through enzyme systems, by the continuous administration of anticonvulsants, for example by phenytoin.
Ergocalciferol Tablets BP 0.25mg may be given to women in the third trimester of pregnancy if justified on medical grounds but the tablets should not be given to lactating mothers.
