Certain circumstances may decrease the effectiveness of birth control pills. Stress or emotional states can alter the functioning of hormones, but they do not affect the contraceptive effects themselves. Therefore, it may be that women experiencing this situation suffer delay in their menstrual period, without this changing the action of contraceptives.

  • Forgetting to take the pill

  • Some medications

  • Vomiting and diarrhea

  • First pill box

  • Alcohol consumption and pill

  • Treatments against depression

Forgetting to take the pill

Do not take the birth control pill in due time and date decreases the contraceptive effect. There is no use taking the next day, as it is not possible to recover the effects of the forgotten pills. The right thing to do is to take two pills the next day. Even so, the effectiveness of the method until the next menstruation was affected.

Some medications

It is preferable to take the pill between six and eight hours after taking other medications. It is important to know that some antibiotics such as cephalosporins or hepatic enzyme inhibitor anticonvulsants (phenobarbital, phenytoin, primidone, among others) can decrease the effect of contraceptives.

Vomiting and diarrhea

In both cases there is a disturbance in the absorption process. If it occurs less than four hours after taking the tablet, vomiting and diarrhea prevent contraceptive absorption, so that the body may not reach the levels of hormones needed to prevent ovulation.

First pill box

If the woman has recently started taking the pill, it is important to know how long it takes to achieve an adequate contraceptive effect. If you start using the contraceptive from the first day of the cycle (first day of menstruation) and take it properly, the contraceptive is effective from the start. On the other hand, if the onset has occurred on the second and fifth days of menstruation, contraception is not effective during the first week of use. Many gynecologists indicate a barrier method during the first month to ensure efficient contraception while assessing adequate pill intake.

Alcohol consumption and pill

The alcohol does not reduce effectiveness contraceptive pills. However, the contraceptive can influence the metabolism of alcohol, leaving the person more susceptible to intoxication with the substance. Although alcohol has no direct effect on the pill, if there is an intoxication that leads to vomiting, the absorption of the pill can be affected and, therefore, its effect. In addition, alcohol is eliminated more slowly in women using the contraceptive pill.

Treatments against depression

The consumption of antidepressant medications, such as imipramine, or natural treatments for the condition, such as the use of St. John’s wort, also known as St. John’s wort, reduce the effectiveness of oral contraceptives. Therefore, in these cases, the association of a non-hormonal method such as condoms is recommended.
