Loyihsin Birth Control Pills: Effectiveness and Lifestyle Concerns

Lohihsin emergency contraceptive pill issues?

Hello Doctor, I would like to ask a few questions: 1.
I took my first pack of Loette birth control pills and consulted with a gynecologist.
The pharmacist said that the contraceptive effect starts after taking seven pills, but I am still a bit worried.
If I have unprotected intercourse after the seventh pill but before the eighth pill, and then have internal ejaculation after taking the eighth pill, what is the likelihood of pregnancy? 2.
The pharmacist mentioned that smoking and drinking alcohol can affect the efficacy of the medication, but I found online and from other doctors that smoking does not impact the contraceptive effect, and drinking alcohol is fine as long as it is not too close to the time of taking the medication.
Can you please clarify if it is safe to smoke and drink alcohol while taking Loette? Thank you, Doctor.

Hello,
For first-time users of oral contraceptives, it is recommended to start taking the pills on the first day of your menstrual cycle.
If you begin taking the pills after the second day of your period, it is advised to use additional contraceptive measures for the first seven days of pill use.

Combined oral contraceptives (COCs) must be taken at the same time every day to achieve a 99% effectiveness rate.
There are several medications that can interact with oral contraceptives:
1.
Antibiotics (such as Penicillin, Cephalosporins, Erythromycin, Sulfonamides, Bactrim, Chloramphenicol, Doxycycline) can reduce the effectiveness of oral contraceptives, as they may decrease the gut flora that aids in absorption.
Therefore, alternative contraceptive methods should be used while taking these antibiotics.

2.
Sedatives (such as Barbiturates) can increase the metabolism of contraceptives, thereby reducing their effectiveness.

3.
Antiepileptic drugs (such as Primidone, Phenytoin, Carbamazepine) can also increase the metabolism of contraceptives, reducing their effectiveness.

4.
Tuberculosis medications (such as Rifampicin, Isoniazid).

5.
Antidiabetic medications (such as Rosiglitazone).

6.
Acetaminophen and Ascorbic acid (Vitamin C) may inhibit estrogen metabolism, potentially increasing estrogen levels and the occurrence of side effects.

7.
Oral contraceptives can affect the action of anticoagulants.

8.
Smoking can increase the metabolism of contraceptives, reducing their effectiveness.

9.
Long-term consumption of certain teas or herbs may have additive or subtractive effects with oral contraceptives.

Additionally, any medication should be taken with water and not with tea, coffee, alcohol, or other beverages, as this may affect the medication's effectiveness.
Therefore, if you need to take any of the aforementioned medications while on oral contraceptives, it is best to implement additional contraceptive measures for seven days.

Thank you! Wishing you safety and health.

Dr.

When it comes to understanding the effectiveness of birth control pills like Loyihsin and their interaction with lifestyle choices such as smoking and drinking, it's important to consider several factors.

1. Effectiveness of Loyihsin Birth Control Pills: Loyihsin, like other combined oral contraceptives, is designed to prevent pregnancy by inhibiting ovulation, thickening cervical mucus, and thinning the uterine lining. According to standard medical guidelines, it typically takes about seven consecutive days of taking the pill for it to become effective in preventing pregnancy. If you have taken the first seven pills correctly, you should be protected from pregnancy. However, if you have unprotected intercourse after taking the eighth pill, the risk of pregnancy is very low, but not zero. The effectiveness of the pill is maximized when taken consistently at the same time each day. If you are concerned about the possibility of pregnancy, consider using a backup method of contraception, such as condoms, during the first month of starting the pill.

2. Impact of Smoking and Drinking on Birth Control Pills: There is a common misconception regarding smoking and its effect on the efficacy of birth control pills. While smoking does not directly reduce the effectiveness of the pill in preventing pregnancy, it is important to note that smoking can increase the risk of serious side effects associated with hormonal contraceptives, particularly in women over 35. This includes an increased risk of blood clots, stroke, and cardiovascular issues. Therefore, if you smoke, it is advisable to discuss this with your healthcare provider to assess your individual risk.

As for alcohol consumption, moderate drinking does not significantly affect the effectiveness of birth control pills. However, excessive alcohol intake can lead to missed doses or vomiting, which can compromise the pill's effectiveness. It is generally recommended to avoid drinking alcohol close to the time you take your pill to ensure that you do not forget to take it or experience any gastrointestinal issues that could affect absorption.

In summary, if you have taken your Loyihsin pills correctly for at least seven days, your risk of pregnancy is low even if you have unprotected intercourse afterward. Smoking does not affect the pill's effectiveness but poses health risks, while moderate alcohol consumption is generally safe as long as it does not interfere with your pill-taking routine. Always consult with your healthcare provider for personalized advice based on your health history and lifestyle.
