Opcicon One-Step Review


Opcicon One-Step is an emergency birth control pill containing levonorgestrel intended for use after contraception failure or unprotected sex.

Contents:

Indications for use

Opcicon One-Step is used as a hormonal emergency contraceptive. The drug is effective in use within 72 hours after unprotected sexual intercourse.

Mechanism of action

Levonorgestrel belongs to the group of drugs containing hormones secreted by the sex glands, intended for emergency contraceptive effect.

Its effectiveness is due to the fact that the drug has the property of interfering with the fertilization of the ovum due to inhibition of ovulation. It is especially effective when used in the first phase of the period, before the ripening of the ovum in the ovary.

Levonorgestrel also causes changes in the endometrium, which prevents the implantation of a fertilized egg.

Dosage and mode of application

The package of Opcicon One-Step emergency contraception contains only one tablet with a full dose of levonorgestrel (1.5 mg), which must be taken within the next 12 hours after unprotected intercourse and no later than 72 hours after it. It is important that levonorgestrel is not an abortifacient – it only hinders the onset of pregnancy, while also reducing the risk of abortion. If the pregnancy has already occurred, the levonorgestrel pill will not stop this condition.

If vomiting occurs within the first 3 hours after taking the pill, another one should be taken immediately.

Taking the drug is possible on any day of the menstrual period if there is no delay in menstrual bleeding.

Use of this drug is not a contraindication to the continuation of regular systemic hormonal contraception.

When using this medication in the first 7 days of taking oral hormonal contraceptives of systemic action, barrier methods of contraception should be used.

The repeated use of emergency contraception during one menstrual period is not recommended.

In most cases, the medication does not affect the character of the menstrual period. However, acyclic bleeding may occur and menstruation may be delayed for several days. If you have a delay in menstruation for more than 5-7 days, you should exclude pregnancy. The appearance of pain in the lower abdomen or fainting can indicate an ectopic pregnancy.

The use of levonorgestrel is not recommended in women with a high risk of developing an ectopic pregnancy.
