Rigavidon 21+7, 0.15 mg+0.03 mg 28 pcs.

How to take, the dosage

Ingestion. 1 tablet a day, preferably at the same time of the day.

If a woman has not taken a contraceptive in her previous cycle and the doctor has not prescribed otherwise: the 1st tablet should be taken on the 1st day of menstruation, and the pills should be continued for 21 days. Then it is recommended to continue taking the reddish-brown pills for 7 days, during which menstrual bleeding occurs. After that, you should continue taking the next package containing 21 white tablets and then 7 reddish-brown tablets – without a break. Each cycle of taking begins on the same day of the week.

If a woman took the contraceptive in a previous cycle and the previous packet contained 21 pills: you must start taking the drug after a 7-day break, on the 8th day.

The composition of the pills of different colors is not the same. Therefore, the beginning and the correct sequence of taking – 21 white pills first, followed by 7 reddish-brown pills – are indicated by numbers and arrows on the package.

If you switch to Rigevidone® 21+7 from another contraceptive, the above chart should be used.

After childbirth or abortion: you may not start until the 1st day of your period of the 1st biphasic cycle. The 1st biphasic cycle is usually shortened due to premature ovulation. If the drug is started as early as the 1st spontaneous bleeding, the drug cannot successfully prevent premature ovulation, so contraception may not be reliable in the first 2 weeks of the cycle.

If the pill is missed within the prescribed period: the missed pill should be taken within the next 12 hours. In this case there is no need to use additional contraceptive methods. It is recommended to take the remaining tablets at the usual time. If more than 12 hours have elapsed, the last missed pill should be taken (skipping the other unused pills) and the drug should be taken normally. In this case, additional contraceptive methods (barrier methods, spermicides) should be used for the next 7 days.

This does not apply to the reddish-brown pills, since they do not contain hormones.

For therapeutic purposes: the dose of the drug and the route of administration are chosen by the doctor for each patient individually.

Interaction

Barbiturates, some antiepileptic drugs (carbamazepine, phenytoin), sulfonamides, pyrazolone derivatives can increase the metabolism of the steroid hormones included in the drug.

Lack of contraceptive effectiveness may also be observed when concomitantly prescribed with some antimicrobials (including ampicillin, rifampicin, chloramphenicol, neomycin, polymyxin B, sulfonamides, tetracyclines), which is associated with changes in the intestinal microflora.

In concomitant use with anticoagulants, coumarin or indandion derivatives, additional determination of the prothrombin index and change of the anticoagulant dose may be required.

The use of tricyclic antidepressants, maprotiline, beta-adrenoblockers may increase their bioavailability and toxicity.

When using oral hypoglycemic agents and insulin, it may be necessary to change their dosage.

When combined with bromocriptine its effectiveness decreases.

When combined with drugs with potential hepatotoxic effects, such as the drug dantrolene, an increase in hepatotoxicity is observed, especially in women over 35 years.

Rigevidone should be used with caution in combination with the drugs listed above.

Special Instructions

Before starting hormonal contraception and every 6 months thereafter, a general medical and gynecological examination is recommended, including cervical smear cytology, assessment of mammary glands, determination of blood glucose, cholesterol and other liver function parameters, BP control, urine analysis).

Prescribing Rigevidone to women with thromboembolic diseases at a young age and a family history of increased blood clotting is not recommended.

The use of oral contraception is allowed no earlier than 6 months after having had viral hepatitis on condition of normalization of liver functions.

In case of severe upper abdominal pain, hepatomegaly, and signs of intra-abdominal bleeding, liver tumor may be suspected. If necessary, the drug should be discontinued.

In case of impaired liver function while taking Rigevidone, a consultation with a general practitioner is necessary.

If acyclic (intermenstrual) bleeding occurs, Rigevidone should be continued, as most of these bleeding stops spontaneously. If acyclical (intermenstrual) bleeding persists or recurs, a medical exam should be performed to rule out an organic reproductive system disorder.

If vomiting or diarrhea occurs, the drug should be continued with another, non-hormonal method of contraception.

Women who smoke and take hormonal contraceptives have an increased risk of cardiovascular disease with serious consequences (myocardial infarction, stroke). The risk increases with age and according to the number of cigarettes smoked (especially in women over the age of 35).
