Contraceptive pills are commonly used by women for birth control due easiness of administration, their effectiveness among others. A single pill may contain either oestrogen, progesterone or both hormones (combined oral contraceptive) which are also found in the body. They inhibit ovulation and create an environment not suitable for implantation of the fertilized egg in the uterus (uterus). However not every sexually active woman of reproductive age is advised to use this method because of risk of serious side effects or worsening of medical conditions which they suffer from.

Here are instances when contraceptive pills are not advised to be used by women:

  • High suspicion of pregnancy
  • Unexplained vaginal bleeding
  • Age of 35 years or older and smoking fewer than 15 cigarettes a day
  • Age of 35 years or younger with worsening migraine headaches associated with previous use of these pills
  • High blood pressure or history of high blood which was pregnancy-related
  • History of yellowing of eyes while using pills in the past liver disease (current or medically treated)
  • Previous diagnosis of breast cancer more than 5 years ago and it has not returned
  • Diabetes mellitus for more than 20 years, or diabetes with damage to blood vessels, vision, kidneys, or the nervous system
  • Active use of drugs for treatment of epilepsy because most of these drugs reduce effectiveness of oral contraceptives
  • Not breastfeeding and less than 3 weeks since giving birth
  • Not breastfeeding and between 3 and 6 weeks after giving birth with additional risk that she might develop a blood clot in a deep blood vessels
