Continuous Use Oral Contraceptive
Continuous use oral contraceptives have been available to Canadian women since the end of 2007. The contraceptive contains two female hormones progestin and oestrogen. The package includes 91 pills. One pill is taken at the same time every day within a one-hour window for three months. The last seven pills do not contain hormones. After taking the last pill, a new pill regimen starts.How do continuous use oral contraceptives pills work?
- They prevent your ovaries from releasing an egg each menstrual cycle (ovulation).
- They change the texture of your cervical mucous creating a barrier for sperm.
- They thin the lining of the uterus, making it harder for a fertilized egg to implant and result in a pregnancy.
Advantages:
- Approximately 99% effective in preventing pregnancy (roughly the same as with other oral contraceptives)
- You will experience 4 menstrual periods per year
- If you experience complications or uncomfortable side effects during your periods this method can help alleviate them.
- It may help reduce acne
Disadvantages:
- You must visit a doctor to obtain a prescription
- Does not protect against sexually transmitted infections (STIs).
- There is currently some controversy over the long term effects or implications of taking hormones for a prolonged period of time.
- Potential adverse effects can occur and may include: breakthrough bleeding (spotting or bleeding between periods), headaches and nasopharyngitis (an inflammation of the nasal passages).
- If you forget to take your pill at roughly the same time every day, the pill becomes less effective.
