Primolut N contains the active ingredient norethisterone, and belongs to a group of medicines called progestogens, which are female hormones. Primolut N can be used in several different circumstances, including to delay or manage your periods.

Do not take Primolut N tablets:

• if you are allergic (hypersensitive) to norethisterone, or other similar hormone medicines, or any of the other ingredients listed in the patient information leaflet
• if you are pregnant or think you might be pregnant
