The contraceptive effect of Regulon tablets is associated with the ability of its constituent synthetic analogs of endogenous hormones estradiol and progestogens to prevent the release of a mature egg from the follicle.

Gynecologists answer these questions like this: if you take the pills correctly (that is, take it according to the scheme described in the instructions and in compliance with all the recommendations of your doctor), then upon completion of their admission you can plan the pregnancy. Usually, pregnancy after Regulon occurs after about 6 months of active sex life.
A woman who plans a child, doctors recommend to stop taking the drug at least three months before conception.
Dosage and method of use
As indicated in the instructions for use Regulon is prescribed inside.
Taking pills start from the 1st day of the menstrual cycle. Assign 1 tab./day for 21 days, if possible at the same time of day. After taking the last pill from the package, a 7-day break is taken during which menstrual-like bleeding occurs due to discontinuation of the drug. The next day after a 7-day break (4 weeks after taking the first pill, on the same day of the week), taking the drug from the next package, which also contains 21 tabs, is resumed, even if the bleeding has not stopped. This pill regimen is followed as long as there is a need for contraception. When complying with the admission rules, the contraceptive effect is maintained for the duration of the 7-day break.
The first dose of the drug:
- The first pill should be taken from the first day of the menstrual cycle. In this case, you do not need to use additional methods of contraception. Taking the pills can be started from 2-5 days of menstruation, but in this case, in the first cycle of using the drug, additional methods of contraception should be used in the first 7 days of taking the pills. If more than 5 days have passed after the onset of menstruation, you should postpone the start of the drug until the next menstruation.
Taking the drug after abortion:
- After an abortion, in the absence of contraindications, it is necessary to begin taking pills from the first day after the operation, and in this case there is no need to use additional methods of contraception.
Taking the drug after childbirth:
- Non-breastfeeding women can start taking pills no earlier than 21 days after delivery, after consulting a doctor. In this case, there is no need to use other methods of contraception. If after childbirth there was already sexual contact, then pills should be postponed until the first menstruation. If you decide to take the drug later than 21 days after delivery, then in the first 7 days you need to use additional methods of contraception.
Transfer from another oral contraceptive:
- When switching from another oral drug (21 or 28 days old): the first tablet of Regulon is recommended to be taken the next day after completing the course of the 28-day package of the drug. After completing the 21-day course, you need to take a regular 7-day break and then start taking Regulon. No need to use additional methods of contraception.
Transition to Regulon after using oral hormone preparations containing only progestogen (“mini-pili”):
- The first tablet Regulon should be taken on the 1st day of the cycle. No need to use additional methods of contraception. If menstruation does not occur when taking a mini-drink, after excluding pregnancy, you can start taking Regulon on any day of the cycle, but in this case, additional contraceptive methods should be used in the first 7 days (using a cervical cap with a spermicidal gel, a condom, or abstinence from sexual intercourse). The use of the calendar method in these cases is not recommended.
Postponement of the menstrual cycle:
- If there is a need to postpone menstruation, it is necessary to continue taking pills from a new package, without a 7-day break, in the usual way. With the postponement of menstruation, breakthrough or spot bleeding may appear, but this does not reduce the contraceptive effect of the drug. Regulon's regular intake can be restored after the usual 7-day break.
Vomiting / diarrhea:
- If after taking the drug appears vomiting or diarrhea, then the absorption of the drug may be defective. If the symptoms stopped within 12 hours, then you need to take another pill extra. After that, you should continue taking the pills in the usual way. If vomiting or diarrhea continues for more than 12 hours, then additional contraceptive methods should be used during vomiting or diarrhea and for the next 7 days.
If a woman forgot to take a pill in a timely manner, and after skipping no more than 12 hours have passed, you need to take a forgotten pill, and then continue taking it at your usual time. If more than 12 hours have passed between taking the pills, this is considered to be skipping the pill, the contraceptive reliability in this cycle is not guaranteed and the use of additional methods of contraception is recommended.
When skipping one pill in the first or second week of the cycle, you need to take 2 tab. the next day and then continue regular intake, using additional contraceptive methods until the end of the cycle.
When you skip a pill in the third week of the cycle, you must take a forgotten pill, continue taking it regularly and not take a 7-day break. It is important to remember that due to the minimal dose of estrogen, the risk of ovulation and / or bleeding increases when you skip a pill and therefore it is recommended to use additional contraceptive methods.

We offer you to read the reviews of people who used the drug Regulon:
- Dasha. She took “Regulon” as a contraceptive, the first course of treatment was 6 months. There were no problems. Yes, and then the price pleased. Unlike similar drugs, the price was lower at more than half the cost. The drug has coped with its goal - there was no pregnancy, the cycle was normal, acne was gone, the hair stopped falling out. But a couple of years later she faced a cycle violation, the doctor again prescribed this drug, bearing in mind past positive experiences. But alas, this time to a significant increase in weight (5.2 kg per month intake), swelling of the legs, arrhythmia of the heart and nausea after taking were added. But the hair and skin really shone. After two months of administration, the drug had to be replaced with a similar one, and all the symptoms disappeared immediately. No longer risk taking it.
- Nastya. I did not dare to take this regullon as a contraceptive, to be honest, I was afraid. My friend took him about 2 years ago not to get pregnant, but she does not say anything good about him. On the contrary, she claims to have gained a lot of weight. Therefore, I did not dare, in any case, it is up to you to decide and go to consult with the gynecologist.
- Oksana. When the question of contraception arose after the birth of my daughter, I, while breastfeeding, used spermicidal suppositories and creams. When breastfeeding stopped, she decided to switch to pills. What to say? “Regulon” copes with its mission as “excellent”. The cost of the pills is quite affordable. From the heap of side effects described in the instructions, I did not feel anything like that. Menstruation came in day to day, of moderate profusion and without pain. Even the migraines that tormented me before the CD passed. By the way, I drank Regulon a few years before pregnancy, and then I managed to get pregnant and give birth to a healthy child safely, plannedly and fairly quickly.
