If you’re concerned about becoming pregnant, the birth control pill (better known as simply “the pill”) is one of the safest, most reliable forms of contraception available.
In this article, we share all you need to know about one of the popular birth control pill brands in Singapore, Microgynon® 30:
- How it works;
- How to take it;
- What to do if you missed a dose;
- Potential side effects; and
- Where to buy Microgynon® 30 in Singapore.
What Is Microgynon® 30?
Microgynon® 30 is a brand-name combination birth control pill. It contains 2 hormones:
- Progestogen (0.15mg levonorgestrel); and
- Estrogen (0.03mg ethinylestradiol).
Microgynon® 30 is mainly used as contraception to prevent pregnancy. However, women taking Microgynon® 30 may also benefit from the non-contraceptive effects of estrogen such as:
- Regulate or lighten menstruation
- Prevent anaemia by making periods lighter or shorter
- Lessen menstrual cramps (dysmenorrhea)
- Manage symptoms of premenstrual syndrome (PMS) and premenstrual dysmorphic disorder (PMDD)
- Treat symptoms of polycystic ovary syndrome (PCOS)
- Treat endometriosis or uterine fibroids
- Lower the risk of ovarian cancer, uterine cancer and colon cancer
- Improve acne
- Stop unwanted hair growth
- Reduce migraines
- Control hot flashes during the transition into menopause
How Does Microgynon® 30 Work?
Microgynon® 30 prevents pregnancy by:
- inhibiting ovulation, which is the release of an egg from the ovary
- thickening the cervical mucus (the fluid in your vaginal tract). This makes it hard for the sperm to reach the egg to fertilise it.
- thinning of the uterine lining, so that even if an egg is fertilised, it will be unable to attach to the uterus. The fertilised egg will instead be passed out of the body.
How Effective Is Microgynon® 30?
According to the Centers for Disease Control and Prevention, when used perfectly, Microgynon® 30 is more than 99% effective in preventing pregnancy. However, possibly due to missed pills or improper storage, Microgynon® 30 is typically around 91% effective.
Birth control pills are generally more effective than male condoms in preventing pregnancy — male condoms are 98% effective when used perfectly, and 82% effective in typical use. However, it is important to note that birth control pills do not protect women against sexually transmitted infections (STIs), unlike male condoms.
Therefore, always use dual protection of condoms and non-barrier contraceptives such as birth control pills during any sexual activity.
How To Take Microgynon® 30 Birth Control Pills?
Microgynon® 30 contains 21 pills. This means that you need to take a pill at the same time every day, for 21 days. You should swallow each pill whole with water. Do not chew the pill.
The back of the pill strip states the days of the week (Monday – Sunday). Start your course by taking a pill marked with the correct day of the week and follow the direction of the arrows on the strip. This is followed by 7 days where no pills are taken.
A few days after taking the last pill from the strip, you will experience a withdrawal bleed, similar to having your period. During the 7 pill-free break, you do not need to use extra contraception such as condoms, as long as you have taken your pills correctly and start the next strip of Microgynon® 30 on time.
What To Do If I Missed My Microgynon® 30 Birth Control Pill?
A regular routine of taking your birth control pills at the same time every day during the 21 days regimen is desirable. This is because taking a pill late or missing doses may affect the effectiveness of the pill in preventing pregnancy.
Microgynon® 30 is considered “missed” if you:
- don’t take it for 24 hours or more after you were supposed to; or
- vomit or suffer from diarrhoea within 3 to 4 hours of pill-taking.
Follow these steps below if you have forgotten to take a pill:
If you are late (less than 24 hours) or missed (24 to 48 hours) an active pill:
You’re still protected against pregnancy if you missed 1 pill anywhere in the pack or started a new pack 1 day (24 hours) late.
Follow these steps:
- Take the late or missed pill immediately.
- Continue taking the remaining pills at the usual time (even if it means taking two pills on the same day).
- Take the 7-day pill-free break as prescribed or if you’re on an everyday pill, take the inactive pills.
- Emergency contraception is not usually needed but can be considered if hormonal pills were missed earlier in the cycle or in the last week of the previous cycle.
- No additional contraceptive protection (e.g. condoms) is needed.
If you missed two or more active pills (48 hours or more):
When this happens, it greatly increases your chances of ovulation. In this case, when you missed 2 or more active pills anywhere in the pack or started a new pack only after 2 days (48 hours) or more, you may not be protected against pregnancy.
What you should do:
- Take the last pill that you missed immediately even if it means taking 2 pills a day.
- Discard any earlier missed pills.
- If the missed pill is within:
- Week 1 (pills 1 to 7) or Week 2 (pills 8 to 14) of the pack:
- Continue to take the active pills in your current pack daily
- Take a 7-day break
- Begin a new pack the next day
- Week 3 of the pack (pills 15 to 21):
- Continue to take the active pills in your current pack daily
- When you have finished taking all the active pills, discard the pack
- Don’t take the 7-day break, begin a new pack the next day
- Week 1 (pills 1 to 7) or Week 2 (pills 8 to 14) of the pack:
- Consider taking emergency contraception if you missed 2 or more pills during the first week of a pack and/or had unprotected sex in the last 7 days.
- Use extra contraception (i.e. condoms) or abstain from sex for the next 7 days.
What Are The Potential Side Effects Of Microgynon® 30?
Women who just started taking Microgynon® 30 may experience some of the following side effects:
- Nausea and bloating. Taking the medication after food may help reduce these side effects.
- Headache. Taking over-the-counter painkillers such as Paracetamol may help manage the pain.
- Vaginal bleeding between periods (spotting)
- Breast soreness
- Mood changes. To avoid huge changes in the hormone levels in your body, it is recommended to take Microgynon® 30 around the same time every day.
These symptoms vary among individuals and normally subside within 2-3 months as your body starts to get accustomed to the changes in hormone levels. Do inform your doctor if you experience any of these symptoms for longer than expected or if they are bothering you.
