Hypertension, which is usually reversible on discontinuing treatment, has occurred in a small percentage of women taking oral contraceptives.
Menstrual pattern: Women taking Norethisterone for the first time should be informed that they may initially experience menstrual irregularity. This may include amenorrhoea, prolonged bleeding and/or spotting but such irregularity tends to decrease with time. If a woman misses two consecutive periods, pregnancy should be ruled out before continuing the contraceptive regimen.
