Emergency Contraceptive Pills: Timing and Side Effects Explained - Obstetrics and Gynecology

Emergency contraceptive pill


On February 21, I had sexual intercourse, but it was through withdrawal.
Later, I thought that there might be some sperm due to the presence of prostate fluid.
On February 22, I bought the emergency contraceptive pill from the brand Lijieting, but it only contained one tablet.
I gave it to my girlfriend at 8 AM.
Since then, she has experienced some mild abdominal pain and slight nausea, but she hasn't been able to vomit.
I would like to ask if it was correct to take the emergency contraceptive pill in this situation, considering that I bought it on the night of February 21 and she took it at 8 AM on February 22.
P.S.
This is her first time having intercourse and her first time taking emergency contraception.

Hello, emergency contraceptive pills should be taken within 48 hours.
Relying on the safe period is not advisable.
It is better to take preventive measures before sexual activity.
Wishing you good health.

More Info


Emergency contraceptive pills (ECPs), such as the one you mentioned (likely containing levonorgestrel or ulipristal acetate), are designed to prevent pregnancy after unprotected intercourse or contraceptive failure. The timing of taking these pills is crucial for their effectiveness. Ideally, ECPs should be taken as soon as possible after the incident, preferably within 72 hours for levonorgestrel and up to 120 hours for ulipristal acetate. In your case, taking the pill the morning after the incident (February 22) is within the recommended timeframe, which is good.

Regarding the side effects you mentioned—mild abdominal pain and nausea—these are common reactions to emergency contraceptive pills. The hormones in these pills can cause temporary changes in the body, leading to symptoms such as:
1. Nausea and Vomiting: This is one of the most common side effects. If vomiting occurs within two hours of taking the pill, it may be necessary to take another dose, as the body may not have absorbed the medication effectively.

2. Abdominal Pain or Discomfort: This can occur as the body reacts to the hormonal changes induced by the pill. It is usually mild and should resolve within a few days.

3. Changes in Menstrual Cycle: After taking ECPs, some women may experience changes in their next menstrual period, which can include earlier or later onset, heavier or lighter bleeding.

4. Fatigue and Headaches: Hormonal fluctuations can also lead to feelings of tiredness or headaches.

It's important to note that while these side effects can be uncomfortable, they are generally not serious and should subside as your body adjusts. However, if your girlfriend experiences severe pain, heavy bleeding, or any other concerning symptoms, it would be wise to seek medical attention.

In terms of the timing of taking the emergency contraceptive pill, your actions were appropriate. Taking the pill the morning after the incident is within the effective window for preventing pregnancy. Since this was her first experience with both sexual intercourse and taking an emergency contraceptive, it is understandable that there may be some anxiety or concern about the process and any potential side effects.

Lastly, it is essential to remember that while ECPs are effective at preventing pregnancy, they are not intended for regular contraceptive use. For ongoing contraception, it would be beneficial for your girlfriend to discuss options with a healthcare provider to find a method that suits her needs and lifestyle.

In summary, taking the emergency contraceptive pill the morning after unprotected intercourse is appropriate, and the mild side effects you mentioned are common. If symptoms persist or worsen, or if there are any signs of complications, it is advisable to consult a healthcare professional for further evaluation and guidance.
