alter table tableName drop constraint constraintName ;
You cannot drop an index being used to enforce uniqueness. You must drop the constraint - which will also drop the index. You also cannot drop a unique constraint being used as a reference of a foreign key. Adding the keyword CASCADE will allow you to get around that, but it will destroy the FK references.
alter table tableName drop constraint constraintName CASCADE ;
