Mercilon: A Low-Dose Combined Oral Contraceptive
What is Mercilon?
Mercilon is a low-dose combined oral contraceptive, commonly known as “the pill.” It contains synthetic versions of the female hormones oestrogen and progestogen (ethinyl estradiol and desogestrel). Mercilon is taken daily to prevent pregnancy and, when used correctly, is nearly 100% effective.
Mercilon is a suitable alternative for women sensitive to higher doses of oestrogen, making it a gentler option while still offering reliable contraceptive protection.
What are the Benefits of Mercilon?
Mercilon provides several benefits beyond preventing pregnancy:
- Immediate Effectiveness: Offers immediate protection if taken on the first day of your period.
- Lighter Periods: Reduces period pain and heaviness.
- Regulated Menstrual Cycle: Helps achieve a more predictable menstrual cycle.
- Reduced Premenstrual Symptoms: Eases mood swings and physical discomfort associated with PMS.
- Lower Risk of Weight Gain: Contains a lower dose of oestrogen, reducing the likelihood of weight-related side effects.
Does Mercilon Protect Against STIs?
No, Mercilon does not protect against sexually transmitted infections (STIs). Only barrier methods such as condoms can prevent the spread of STIs.
If you are concerned about possible exposure to an STI, consult your healthcare professional or visit a sexual health clinic.
How Does Mercilon Work?
Mercilon prevents pregnancy by altering the body’s natural reproductive processes in three key ways:
- Stops Ovulation: Prevents the release of an egg from the ovaries.
- Thickens Cervical Mucus: Makes it harder for sperm to reach the womb.
- Thins the Uterine Lining: Reduces the likelihood of a fertilised egg implanting in the womb.
These mechanisms combine to provide highly effective contraceptive coverage.
How to Take Mercilon?
Starting Mercilon
- Begin taking Mercilon on the first day of your period for immediate protection.
- If started later, use additional contraception (e.g., condoms) for the first seven days.
Daily Routine
- Take one pill daily for 21 consecutive days, ideally at the same time each day.
- Swallow the pill whole with water, with or without food.
Pill-Free Week
- After 21 days, take a seven-day break with no pills.
- During this break, you may experience withdrawal bleeding, similar to a period.
Resuming Mercilon
- Start your next pack on the eighth day, even if you are still bleeding.
- If taken correctly, you remain protected during the pill-free week.
What to Do If You Miss a Pill?
Missed One Pill (<12 Hours Late)
- Take the missed pill as soon as possible.
- Continue with your pack as usual.
- No additional contraception is needed.
Missed Two or More Pills (>12 Hours Late)
- Take the most recent missed pill immediately.
- Skip earlier missed pills and continue with the pack.
- Use barrier contraception (e.g., condoms) for the next seven days.
Note: If you have had unprotected sex after missing pills, consider emergency contraception.
