Da thalidomid kan findes i sæd, skal mandlige patienter benytte kondom i behandlingsperioden og i 1 uge efter pausering og/ eller behandlingsophør ved samleje med en gravid kvinde eller en kvinde i den fertile alder, der ikke benytter effektiv prævention.
As thalidomide is found in semen, male patients must use condoms during treatment and for 1 week after dose interruption and/ or cessation of treatment when having sexual intercourse with a pregnant woman or with a woman with childbearing potential who is not using effective contraception.
