Wera Review

Wera is a low dose monophasic birth control. It contains 2 female hormones: progestin and estrogen to prevent pregnancy.


Indications for use

Wera is prescribed for contraception, dysmenorrhea, infertility, uterine hypoplasia.

Mechanism of action

Wera relates to a contraceptive means. It is a combined low dose drug containing estrogen and progestin. It is devoted to inhibits pituitary secretion of gonadotropic hormones. The main mechanism for achieving a contraceptive effect includes due to the blocking effect of the gestagen and estrogenic drug components influencing the hypothalamic-pituitary-ovarian system.

Ethinyl estradiol is the estrogen component which is known as a synthetic analog of the follicular hormone – estradiol, which takes part in the formation of the hormone of the corpus luteum (progestin) in the menstrual cycle regulation and even formation. The progestin component is norethisterone acetate, which suppresses LH and FSH synthesis by the pituitary gland (preventing follicle maturation). It results in blocking ovulation. Due to the combination of estrogen with progestin, Wera when taking correctly can both stimulate and delay menstruation and help arrest acyclic uterine bleeding.

Mode of application and dosage

Wera is a birth control containing estrogen and progestin. The duration of the regimen is 28 days. 21 pills of Wera contains the definite hormone dosage when the latest 7 are considered to be placebo containing no hormone. A pill should be taken daily at one and the same time. The daily regimen allows regulating the hormone level in the female body to proper suppression of ovulation. A pill should be washed down with water. The second third days of placebo application will bring menstruation.

If you have any questions relating to when to start taking birth control it is better to consult a doctor.

Barbiturates, antiepileptic drugs (carbamazepine, phenytoin) magnify steroid hormones’ metabolism. Antibiotics (ampicillin, rifampicin), changing the intestinal microflora, decrease the reliable concentration. Means for local anesthesia, narcotic analgesics, anxiolytics, antiepileptic drugs, some antihypertensive drugs, ethanol reduces the contraceptive reliability. The correction of the dosing regimen of hypoglycemic drugs may be required if taken together with Wera.

What if I miss a dose?

If a woman is late in taking the pill for less than 12 hours, there is no effect on the contraceptive reliability. The pill must be taken immediately, as soon as the woman understands the pill is missed. The next tablet should be applied at a common time.

If a woman is late in taking the tablet for more than 12 hours, there is a dramatic effect on the contraceptive reliability. The risk to become pregnant is higher than average. In this case, you must follow the basic regulations and apply proper measures:

  • the tablets’ application should never be interrupted for more than 7 days;
  • it is required a 7-day period of continuous administration of pills to reach the mandatory suppression of the hypothalamic-pituitary-ovarian system.

Wera and pregnancy

Wera is prescribed as a means to prevent pregnancy but contraindicated during pregnancy. It is a confirmed fact that the application of birth control pills at the early stages of pregnancy may provoke developmental defects in the fetus. When the diagnosis “Pregnancy” is established any hormonal contraception should be withdrawn.

Breastfeeding is also a period during which it is banned to take Wera. It is necessary to discontinue the preparation while breastfeeding as breast milk composition may be influenced by hormones.
