Summary
503 women were given continuous treatment with norethisterone 0.35 mg. (‘Noriday’) daily for 2,555 cycles. One pregnancy occurred due to method failure, and 4 due to pill omissions. The patients found continuous daily tablet taking easy to remember. During treatment they felt well and many recovered from side-effects experienced during previous medication on the conventional ‘pill’. Changes occurred in cycle characteristics during treatment, but the incidence of unwanted effects fell rapidly after the initial cycles. The inconvenience only caused a 5.2% withdrawal. Medical adverse reactions were notably absent and less than observed on the combined oestrogen/progestogen pill, and 10% discontinued for purely social and unrelated causes.
