If missed 1 birth control pill

Hormonal agents with contraceptive properties are considered as the most effective method of preventing unwanted pregnancy. The correct birth control pills according to the manufacturer’s instructions is 98% of the cases. But what to do if missed 1 birth control pill?

The degree of reduced effectiveness of contraceptive depends on the amount of wasted time and day of the menstrual cycle. If a woman forgot to take birth control pills, the correct decision will be the local use of barrier methods of contraception. Emergency measures is considered as an exception to the rule.

The mechanism of action of hormonal contraceptives

Single-component drugs based on progesterone are taking at the same time. If for any reason the woman drank the medicine, it is taken within the next 12 hours. Many gynecologists do not recommend to drink a shock dose of hormones for a short period of time because of the probability of occurrence of side effects such as:

  • the liver;
  • functional disorders of the digestive system;
  • the emergence of intermenstrual bleeding or amenorrhea;
  • the emergence of thrombosis;
  • violations of the microbial landscape of the vagina;
  • high pressure;
  • increase of body weight;
  • migraine;
  • depression;
  • unpleasant sensations in the mammary glands.

High dose of the hormone contained in a single pill does not provide for re-applying before the set time.

Monophasic contraceptives contain equal amount of estrogen and progestogen, which remains unchanged over the course of the application. Such drugs include Regulon, Janine, Femoden, Silhouette, Gestodene, LOGEST, Rigevidon, Minisiston, yasmin, Jess. These funds are accepted from the first day of the menstrual cycle. If there was a pass reception for 1 – 3 days, doctors recommend go to spermicides, or condoms until the next cycle. New packaging drink 1 to 21 days of the menstrual cycle. After a seven-day break, continue to drink monophasic means even if my period has not stopped.

The skip taking birth control pills requires the use of additional protection from unwanted pregnancy in the form of local non-hormonal means of contraception. In such cases, it is recommended to use the cervical cap with spermicidal gel, condom, or intravaginal candles pharmatex, Benateks.

Biphasic contraceptive pills consisting of estrogen and progestogen, used widely among women of different ages (Femoston, Anteovin, Minardil, Equilar). In these preparations the dosage of estrogen is the same in all the tablets and dose of progestogen changes in the first and second periods. Tablet should drink 1 to 28 day cycle daily.

If for any reason a woman was allowed to skip taking the medicine (lost or took a break), missed a pill you need to drink as early as possible within 12 hours. If omitted 2 3 day of admission, the effectiveness of contraception is greatly reduced. However, this is not the reason for the rejection of the use of the drug. Medication continue to take in order to avoid premature onset of menstruation. Spermicidal preparations are used topically to prevent sexual contact during this period (Patentex, Oval).

Three-phase oral contraceptives are characterized by a threefold change the dose of hormones throughout the menstrual cycle (Three regolith, Three merci, Triziston). Tablets for easy application and variety of colors. Each group drink once a day 1 pill during the cycle (from 1 to 28 days). When skipping the regular pills take it within 12 hours to avoid loss of contraceptive effect.

If the menstrual cycle is not regular, then the three-phase facility accepted after 10 to 14 days of treatment with progestogen contained in monophasic preparations. For maximum effect, the time interval should not exceed 36 hours. This will allow you to maintain a constant concentration of hormones in the blood. Be aware that when you use a contraceptive in the second half of the week the menstrual cycle is sometimes reduced for a few days.

If the drug finished before the required deadline (not accepted last tablet) quantity 28 pieces per pack, special reason for concern there. The last seven pills in most cases do not contain hormones.

However, in case of untimely reception of the next package (not the pill is taken at the time specified in the instructions) mandatory use of emergency contraception. In the future, the pill is carried out according to the scheme. It is worth noting that the maximum risk is present in the first week of use of a contraceptive drug.

Special attention should be paid to the combination contraceptives with other drugs for the treatment of systemic diseases. Their simultaneous use reduces the effectiveness of contraceptives. This applies to the following drugs:

  • barbiturates;
  • TB;
  • antibacterial;
  • antifungal;
  • hormonal;
  • antihistamines;
  • the antispasmodics;
  • laxative;
  • sorbents.

What to do in case of emergency?

If a woman missed receiving birth control pills for a few hours (up to 12), the reduction of the effectiveness of hormones is not marked . In this case, you can not worry about the consequences and enjoy the next pill as soon as possible. One missed appointment for up to 12 hours does not play a big role. But what if the omission of significantly exceeds the allowable time period?

The use of additional methods of protection in the form of a condom, diaphragm, spermicidal funds (vaginal suppositories, suppositories) during sexual activity will reduce the risk of unplanned pregnancy. But that is not always (vaginal suppository may be lost, the woman had no time to take a contraceptive or tend to forget). In this case, come to the aid of hormonal emergency actions (Escape, Postinor).

Emergency measures of contraception used after unprotected sexual intercourse, as well as for suspected ineffectiveness of applied contraceptives.

Drink the medication in the first 72 hours after intercourse. If during this period were vomiting, you must drink to re-pill. Than ever before drinking a tablet, the more noticeable the effect. This circumstance is explained by the fact that released from the follicle unfertilized egg is viable for up to 24 hours. Intake of synthetic hormones prevent the process of fertilization and fixing of a fertilized egg in the uterine wall. Men’s sperm has a different degree of activity (motility) of sperm, so strict adherence to instructions contributes to the achievement of the expected result.

Contraceptives emergency actions to take during a menstrual cycle any day. Means of local protection use is mandatory in regular sexual intercourse before the onset of the next menses. Excess doses of hormones are strictly contraindicated because of the high probability of bleeding.

In case of delay of menses more than 7 days or change in the nature of vaginal bleeding requires the additional consultation of a gynecologist to exclude pregnancy. Severe pain in lower abdomen, nausea, vomiting, fainting can indicate a developing ectopic pregnancy.


Taking birth control pills with a high content of hormones, necessary to understand the degree of risk to the body. Sharp changes in hormonal levels negatively affects all organs and systems.

Especially sensitive to hormonal imbalance women with existing diseases of the endocrine system, the urogenital system (diseases of the liver and kidneys, biliary tract, Crohn’s disease).

Absolute contraindications to the use of emergency contraception are the following factors:

  • the onset of pregnancy;
  • lactation;
  • existing blood disorders (clotting, thrombosis, bleeding of unknown etiology);
  • severe liver disease;
  • epilepsy;
  • idiosyncrasy of the drug;
  • diabetes mellitus (especially the severe form);

The presence of at least one of a provoking factor creates prerequisites for further consultation with the attending physician.

Once disturbed the natural level of hormones subsequently heavily restored. To restore normal physiological parameters may take months or even years.

The decrease in efficiency noted in functional disorders of the digestive system (Crohn’s disease).


Timely adopted contraceptive systemic action prevents unplanned pregnancy. Contraceptives used topically, reduces the likelihood of fertilization in the absence of systemic therapy. Taking the decision on emergency prevention, you need to realistically assess the risk of complications due to abrupt change in hormonal levels. Consultation of a gynecologist will be the best way to resolve this situation.



I want to remind women, lactating that the first dose should be no earlier than 21 days after childbirth (before healing of the wound surface). But if the sexual contact was, the contraceptive is taken with the beginning of a new menstrual cycle (in the absence of breastfeeding). If you have made a pass at the top of the loop for a few days, you need to use additional contraception (barrier methods).


If you want to change contraceptive, no need to make a break in the reception means. When you have finished drinking it the next day you can start drinking new, without worrying about the consequences.


I want to share my experience. I had a situation where it was necessary to delay my period. The doctor advised me to use pills Regulon with new packaging, not withstanding a break of 7 days. Introduced breakthrough bleeding had absolutely no effect on the contraceptive effect.


Contraceptives emergency actions negatively affect the body. After applying Postinor I had to restore the menstrual cycle in six months. Perhaps some girls think it’s better than traumatizing an abortion. It is argued that it is better to discuss with your personal gynecologist.
