C1-ESTERASE INHIBITOR - INJECTION

COMMON BRAND NAME(S): Cinryze

USES: This medication is used to help prevent swelling problems that occur with a certain immune disease passed down through families (hereditary angioedema-HAE). HAE is caused by low levels or improper function of a natural substance produced by the body (C1-inhibitor).

This medication increases the level of C1-inhibitor to help prevent attacks of sudden swelling due to hereditary angioedema.
