For both men and women using this treatment, contraception must be used as it is important not to conceive a child while being treated with Ceplene and IL-2.
Ravimit saavad patsiendid (nii mehed kui ka naised) peavad kasutama rasestumisvastaseid vahendeid, sest Ceplene ja IL- 2 ravi vältel ei tohi rasestuda.
