What is Levonorgestrel (emergency contraception)?
Levonorgestrel is the active ingredient in emergency contraceptive pills — the 'morning-after pill' — used to prevent pregnancy after unprotected sex or when a regular method has failed, such as a burst condom or missed pills. In Nigeria it is sold over the counter and is extremely widely used, best known by the brand names Postinor-2 (Gedeon Richter) and the locally made Postpill and Lydia Postpill (DKT). It is a single-use, backup method — not a routine form of family planning.
Levonorgestrel works mainly by delaying or preventing the release of an egg (ovulation). If there is no egg to be fertilised, pregnancy cannot start. Importantly, it does not end an existing pregnancy and is not an abortion pill — if you are already pregnant, it will not work and will not harm the pregnancy. Because it acts before fertilisation, timing is everything: the sooner it is taken after unprotected sex, the better it works.
Emergency contraception should be taken as soon as possible, ideally within 72 hours (3 days) of unprotected sex; it still has some effect up to 120 hours (5 days) but becomes less reliable each day. Older packs come as two 0.75mg tablets taken together (or 12 hours apart), while newer packs are a single 1.5mg tablet — both are equivalent. It is a safe, one-off measure, but it is less effective than regular contraception and offers no protection against sexually transmitted infections, so it should not replace condoms or ongoing family planning. Genuine packs carry a NAFDAC registration number.
What is Levonorgestrel (emergency contraception) used for?
In Nigeria, Levonorgestrel (emergency contraception) is commonly used for:
- Preventing pregnancy after unprotected sex
- Backup after a contraceptive failure — a burst or slipped condom, or missed combined pills
- A single emergency measure when no regular method was used
- Reducing the risk of pregnancy when taken as soon as possible, ideally within 72 hours
- A safe over-the-counter option that does not affect an existing pregnancy
Dosage
IMPORTANT
Always follow your doctor's or pharmacist's instructions. The information below is for general reference only.
Adults
Take the emergency contraceptive as soon as possible after unprotected sex. For a single 1.5mg tablet (e.g. Postpill), take one tablet once. For the two-tablet 0.75mg pack (e.g. Postinor-2), take both tablets together, or one tablet followed by the second 12 hours later. It works best within 72 hours (3 days) and can be used up to 120 hours (5 days), becoming less effective the longer you wait. If you vomit within 2-3 hours of taking it, take another dose, as the first may not have been absorbed.
Children
Emergency contraception can be used by adolescents of reproductive age who need it, following the same dosing. Young people should ideally also be linked to a health worker for advice on ongoing contraception and protection against sexually transmitted infections.
Elderly
Not applicable — emergency contraception is used by people who can become pregnant.
Emergency contraception is a one-off backup, not a routine method — it is less effective than regular contraception (the pill, injection, implant, or IUD) and should not be relied on repeatedly. Using it more than occasionally is a sign you would benefit from a regular method. It does not protect against HIV or other sexually transmitted infections. Your next period may come earlier or later than usual; if it is more than a week late, take a pregnancy test.
Side Effects
Common side effects
- •Nausea, and sometimes vomiting
- •Irregular bleeding or spotting, or a change in the timing of your next period
- •Tiredness, headache, or dizziness
- •Breast tenderness
- •Lower abdominal (period-like) cramps
Serious side effects — seek medical help immediately
- Severe lower abdominal pain 3-5 weeks later, which could signal an ectopic (tubal) pregnancy — seek medical care
- Signs of an allergic reaction: rash, swelling of the face or throat, or difficulty breathing
- A period that is very late, very light, or unusual — take a pregnancy test and see a health worker if pregnant
When to see a doctor
See a health worker if your period is more than a week late (to rule out pregnancy), if you have severe or one-sided lower abdominal pain in the weeks afterwards (a possible ectopic pregnancy), or if you find yourself needing emergency contraception often — that is a signal to start a reliable regular method. Also seek advice if there is any chance you were exposed to a sexually transmitted infection, as the morning-after pill does not protect against them.
Warnings & Precautions
Do not take Levonorgestrel (emergency contraception) if you have:
- Do not use if you are allergic to levonorgestrel
- It will not work if you are already pregnant — but it does not harm an existing pregnancy
- It is not intended as a regular, repeated method of contraception
- It does not protect against HIV or other sexually transmitted infections
Drug interactions
- •Some medicines reduce how well emergency contraception works, including certain anti-epileptics (carbamazepine, phenytoin), rifampicin (a TB medicine), and the herbal remedy St John's Wort — a copper IUD or a higher dose may be advised if you take these
- •Efavirenz-based HIV treatment can reduce its effectiveness
- •It does not make regular contraceptive pills less effective, but if you are starting or continuing regular pills, use condoms as backup for the next 7 days
Pregnancy & Breastfeeding
Levonorgestrel emergency contraception does not end or harm an existing pregnancy — if you are already pregnant it simply will not work. It is considered safe while breastfeeding; a common precaution is to breastfeed just before taking the dose. After using emergency contraception, consider starting or restarting a regular contraceptive method, and use condoms in the meantime.
