Mercilon Contraceptive Pill
Mercilon is a low-dose combined oral contraceptive pill (‘the Pill’) used to prevent pregnancy. It contains two types of female sex hormones: oestrogen (ethinylestradiol) and progestogen (desogestrel). These hormones work together to prevent pregnancy by inhibiting ovulation, thickening cervical mucus to hinder sperm movement, and altering the uterine lining to prevent implantation.
How Does It Work?
Mercilon prevents pregnancy through three primary mechanisms:
- Inhibition of Ovulation: Prevents the release of an egg from the ovaries.
- Thickening of Cervical Mucus: Makes it more difficult for sperm to enter the womb.
- Alteration of the Uterine Lining: Reduces the likelihood of implantation of a fertilized egg.
When taken correctly, Mercilon is 99% effective in preventing pregnancy.
How Long Does Mercilon Take to Work?
- Starting on Day 1 of Your Period: If you take Mercilon on the first day of your period, you will be protected from pregnancy immediately.
- Starting at Any Other Time: If you start Mercilon on any other day of your cycle, you should use additional contraception (such as condoms) for the first 7 days.
If switching from another contraceptive pill, follow your doctor's guidance to ensure continuous protection.
Standard Method:
- Daily Intake: Take one pill daily for 21 consecutive days.
- 7-Day Break: After 21 days, take a 7-day break during which you may experience a withdrawal bleed.
- Next Pack: Start the next pack immediately after the 7-day break.
Alternative Regimens:
- Tricycling: Take one pill daily for 9 weeks (63 days) without a break, followed by a 4 or 7-day break before starting the next cycle.
- Continuous Use: Take one pill daily without any breaks.
- Flexible Extended Use: Take one pill daily for at least 21 days. If you experience unacceptable bleeding, take a 4-day break, then resume taking the pill daily for at least another 21 days.
Administration Tips:
- Consistency: Take the pill at the same time each day to maintain effectiveness.
- Missed Dose: If you miss a pill, refer to the patient information leaflet or consult with a healthcare professional for guidance.
