Oral contraceptive pills are a very effective method of contraception. The commonly used "combined" pill contains 2 synthetic hormones which prevent ovulation. They usually come in 21-day or 28-day packs. The first tablet is taken between the 1st and 5th day of the menstrual cycle, and then continued with 1 tablet a day. If using the 21-day pack, there should be a break of 7 days before starting the next pack. For the 28-day pack, there is no break between finishing one pack and starting the next.
The Pill is very effective and convenient and does not interfere with love-making. For many women, it relieves menstrual-related problems such as premenstrual tension, painful periods and excessive or irregular bleeding. It also protects against cancer of the uterus and ovary. However, its contraceptive effectiveness drops if it is not taken regularly, or when the woman has vomiting or diarrhoea, and may be affected by some drugs. Under such conditions, extra protection may be needed. The Pill may not be suitable for women with high blood pressure, diabetes or liver disease. Heavy smokers, women who are at risk of cardiovascular diseases and those with abnormal blood clotting should avoid the Pill. Some women may experience mild side effects such as nausea, weight gain, dizziness or headaches which are usually transient and disappear after a few weeks. Before a woman starts on the Pill, she should consult a doctor to find out whether she has any conditions which may affect her usage of the Pill. She should continue to have regular health check-up while taking the Pill.
