Levonelle 1500 microgram Tablet

Buy Levonelle for Emergency Contraception

Levonelle 1500 is an emergency contraceptive that can be used within 72 hours (3 days) of unprotected sex or if your usual contraceptive method has failed. This includes if your contraception method was used incorrectly, for example if a condom slipped away or was used in a wrong way, or if a vaginal pessary or diaphragm changed position, burst, was broken or taken out ahead of time. Levonelle prevents about 84% of expected pregnancies when taken it within 72 hours of having unprotected sex. It will not prevent a pregnancy every time and is more effective if you take it as soon as possible after unprotected sex.

All our products are genuine UK medicines and are dispensed by our partner pharmacy based in the UK.

Start Consultation

Levonelle 1500 contains a synthetic hormone like active substance called levonorgestrel. It is thought to work by stopping your ovaries from releasing an egg and by preventing sperm from fertilising any egg you may have already released.


Do not take Levonelle:

  • if you are allergic (hypersensitive) to levonorgestrel or any of the other ingredients listed in the patient information leaflet
  • if you are pregnant or think that you may already be pregnant - Levonelle 1500 cannot terminate pregnancy
Pregnancy and Breastfeeding

If you are pregnant or breastfeeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking any medicine.

Important Interactions

You must tell your doctor if you are taking, have recently taken (within the last 4 weeks) or might take other medicines, in particular:

  • barbiturates and other medicines used to treat epilepsy (for example primidone, phenytoin, and carbamazepine)
  • medicines used to treat tuberculosis (for example, rifampicin, rifabutin)
  • treatment for HIV (ritonavir, efavirenz)
  • a medicine used to treat fungal infections (griseofulvin)
  • herbal remedies containing St John's wort (Hypericum perforatum)

Levonelle 1500 may also affect how well other medicines work, including a medicine called cyclosporin (which suppresses the immune system).

Please refer to the Levonorgestrel Patient Sheet for important information.

Side Effects
  • feeling sick (nausea)
  • being sick (vomiting)
  • irregular bleeding until your next period
  • lower abdominal pain
  • tiredness
  • headache
Please Note

See a doctor urgently if you have any lower abdominal pain or abnormal vaginal bleeding 2-6 weeks following treatment. These are the main symptoms of an ectopic pregnancy. This is rare, but it is best to be aware of the possibility as it is a serious condition. Also see a doctor if your next period is more than seven days late or if you have any other concerns.

All medication can cause side effects. We have only listed a few to be aware of. Details of all side effects, including rare side effects to be aware of, are listed in the patient information leaflet (PIL). When completing your medical questionnaire, it is very important that you answer the questions truthfully. This is to ensure your doctor has a full picture of your medical history before prescribing. List all medicines you are already taking, including non-prescription and herbal medicines.


ellaOne is another tablet form of emergency contraception. An alternative method of emergency contraception is to have an intra-uterine device (IUD) inserted by a doctor or nurse. This can be done up to five days after unprotected sex. It has the advantage of providing ongoing contraception and is also more effective than taking hormone tablets (it is almost 100% effective). You should visit your regular GP for this.

Looking after your medicine

Do not take medicines after the expiry date stamped on the pack. Keep all medicines out of the reach and sight of children.

Medicines are only intended to be used by the person they are prescribed for. Do not give your prescribed medicine to anybody else, even if they have the same symptoms as you. Medicines can be harmful if used by anybody other than the person they have been prescribed for.

Levonelle 1500 can only prevent you becoming pregnant if you take it within 72 hours of unprotected sex. It does not work if you are already pregnant. If another unprotected intercourse takes place after the use of Levonelle 1500 (also if this is during the same menstrual cycle), the tablet will not exert its contraceptive effect and there is again the risk of pregnancy.

If you did not use a condom (or if it has been torn or slid down) during intercourse, it might be possible that you have caught a sexually transmitted disease or the HIV virus. This medicine will not protect you against sexually transmitted diseases, only condoms can do this. Ask your doctor, nurse, family planning clinic or pharmacist for advice if you are worried about this.

You should only use Levonelle in emergencies and not as a regular method of contraception. If Levonelle is used more than once in a menstrual cycle, it is less reliable and it is more likely to upset your menstrual cycle (period). It does not work as well as regular methods of contraception. Please talk to your GP or family planning clinic about long-term methods of contraception which are more suitable.
