Indications for use

The pill urgently terminates the pregnancy during the first 72 hours after unprotected sex, or in circumstances such as skipping birth control pills, using a poor-quality condom during intercourse.

Mechanism of action

Preventeza belongs to the group of drugs that affect ovulation. It is an emergen-cy contraceptive. The active ingredient – levonorgestrel, reduces the likelihood of pregnancy, including during the follicular phase, when the probability of conception is especially high.

The effect of levonorgestrel 1.5 mg has been little studied. It affects the mucous membrane of the uterus, preventing the attachment of a fertilized egg. When the attachment of the egg has already begun, the effectiveness of the drug decreases to zero. The percentage of successful prevention of fertilization with the use of the drug is 84%. The effect on blood coagulability, as well as on metabolic factors, is not significant. The pill is taken orally. It is well absorbed in the digestive tract and starts to work actively 2 hours after administration. The percentage of drug absorption is 100%. It is excreted mainly with urine and feces within 26 hours.

Dosage and mode of application

You need to take only 1 pill orally, with water, regardless of meals. Take the pill as soon as possible after unprotected sex. The sooner this happens, the higher the chances to prevent pregnancy. If more than 72 hours passed after unprotected intercourse, the drug is ineffective.

Nausea and vomiting can occur 3 hours after taking the pill. In this case, you need to take another tablet of Preventeza.

The pill can be taken any day, regardless of the menstrual cycle, if the previous menstruation was normal. After taking the pill, you will need to use barrier methods for preventing pregnancy.

The medicine usually does not cause menstrual irregularities but minor changes canoccur. It is not recommended to take the drug twice in the same menstrual cycle.

The levonorgestel pill does not prevent STIs, as well as an ectopic pregnancy.

Overdose

An overdose of levonorgestel can cause minor menstrual irregularities and vomit-ing. If you have signs of excess doses, symptomatic treatment is recommended since there is no specific antidote.

Side effects

Preventeza emergency contraceptive can cause the following side effects: nausea, diarrhea, pain in the lower abdomen, pain and emphase in the mammary glands, late or early periods, anxiety, migraine, fatigue, Quincke’s edema, skin rash and hives itching.

If your period is delayed for longer than 5 days, it is recommended to do a preg-nancy test.

If you have inflammatory diseases of the pelvis, pain in the lower abdomen, and have ever had operations in the pelvic area, it is strongly recommended to care-fully check for an ectopic pregnancy.

Contraindications

Preventeza is contraindicated for use in the presence of the following fac-tors:

  • hypersensitivity to levonorgestrel;
  • intolerance to lactose and galactose;
  • lactase deficiency;
  • severe liver disease;
  • age under 16 years;
  • pregnancy (levonorgestrel is not used to terminate a pregnancy that has already occurred).

The pill is used with caution in patients with malabsorption, Crohn’s disease, since such diseases can reduce the effect of the drug.

Interactions

Tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including over-the-counter medicines or herbal medicines.

Some drugs may interfere with the correct action of levonorgestrel. If you have taken the following drugs over the past 4 weeks, the contra-ceptive may be less effective for you. Your doctor may prescribe another type of emergency contraceptive (non-hormonal), such as a copper-containing intrauterine device:

  • barbiturates and other drugs for the treatment of epilepsy (for example, primidone, phenytoin and carbamazepine);
  • drugs used to treat tuberculosis (e.g. rifampicin);
  • HIV medications (e.g. ritonavir, efavirenz);
  • drugs for the treatment of fungal infections (griseofulvin);
  • herbal preparations containing Hypericum perforatum (Hypericum perforatum).

If you need further guidance on determining the correct dose for you, contact your pharmacist or doctor.

After taking the pill, consult your doctor as soon as possible to get fur-ther recommendations regarding a reliable method of regular contraception and to exclude pregnancy.

Levonorgestrel may also interfere with the correct action of cyclosporine (a drug that suppresses the immune system).

If you are taking one of the above drugs, consult your doctor or pharmacist before taking this emergency contraceptive.

Pregnancy and breastfeeding

Taking Preventeza during pregnancy does not make sense since pregnancy has already occurred. However, the use of levonorgestrel 1.5 mg during pregnancy is safe and will not harm the health of the mother and fetus. This is especially important if the woman was not sure of her pregnancy and was taking levonorgestrel. In such a situation, the decision to maintain a pregnancy can be made without concern.

Levonorgestrel passes into breast milk. The use of Preventeza during lacta-tion is possible only with temporary interruption of breastfeeding.

What if I miss a pill?

The pill prevents 85% of cases of unwanted pregnancy if you take it within 72 hours after unprotected intercourse. If more than 72 hours have passed after unprotected intercourse, you can still take a pill and also consult a doctor.

Precautions

This drug is intended for emergency contraception and does not replace regular contraception. It is recommended to use regular contraception after the intake of this emergency contraceptive: barrier contraceptives, such as a condom, should be used until you have your next period.

Do not use this drug as a means of constant and continuous contraception because this leads to a decrease in the effectiveness of the drug and an increase in adverse reactions. If you have regular sexual activity, constant methods of contraception should be used.

Levonorgestrel 1.5 mg does not prevent fertilization in 100% of cases. In the time of sexual intercourse is not known exactly or when more than 72 hours have passed since unprotected sexual intercourse, the probability of fertilization is high. If you miss your period for more than 7 days or you suspect you might be pregnant, consult your gynecological as quickly as possible.

If you used the drug due to an error in regular hormonal contraception and you have no period in the next seven-day break, pregnancy should be excluded.

If vomiting occurs within 3 hours after taking the pill, the effectiveness of the contraceptive is reduced.

Gastrointestinal diseases associated with impaired absorption reduce the absorption of levonorgestrel, which can also affect its effectiveness.

The pill can be taken on any day of the menstrual cycle under the condition that the previous menstruation was normal.

The emergency contraception pill usually does not violate the regularity and nature of menstruation. Sometimes you may have a late or early period.

Repeated use of the Preventeza pill during the same menstrual cycle should be avoided.

If you have ever had an ectopic pregnancy, surgical operations on the fallopian tubes, inflammatory diseases of the pelvic organs, the use of levonorgestrel 1.5 mg can serve as an additional risk factor for an ectopic pregnancy. If you have pain in the lower abdomen, fainting, a history of ectopic pregnancy, surgery on the pelvic organs or their inflammation, an extrauterine pregnancy should be excluded.

The medicine does not protect you from sexually transmitted diseases.
