NEURASAN® therapy is not used to treat patients undergoing chemotherapy or radiation therapy, as reliable data on the interaction of the active ingredients is to date not available.
The same applies to penicillin antibiosis (i.e. if a patient is being treated with penicillin at the time of therapy, e.g. because of an infection). Also, NEURASAN® therapy is not applied during pregnancy and lactation on account of insufficient clinical experience.
