Three Side Effects of Emergency Contraception

Emergency contraception is becoming increasingly popular among the majority of women as an effective method of contraception for necessary situations. This article provides a detailed introduction to effects of emergency contraception.


What is Emergency Contraception?

Concept and Application:

Emergency contraception is a short-term contraceptive method, typically used after unprotected sexual intercourse or when contraception fails. Containing levonorgestrel or ulipristal acetate as the main ingredients, it is commonly known as the “morning-after pill” and is considered an effective measure to prevent pregnancy if used correctly and timely.

Purpose of Use:

The primary goal of emergency contraception is to prevent ovulation, thicken cervical mucus, and thin the uterine lining, thereby preventing the fertilization and implantation of the egg. It is generally used within 72 hours of unprotected intercourse or within 120 hours when using ulipristal acetate, aiming to prevent the process of conception, giving women additional time to make decisions about pregnancy.

Side Effects of Emergency Contraception

  1. Nausea and Vomiting:
    • Incidence of Vomiting: After taking emergency contraception, some women may experience vomiting as a natural reaction to the active ingredients in the medication. Vomiting usually occurs within 1-2 hours after taking the pill and can last for a short duration.
    • Impact on Health and User Experience: The side effects of emergency contraception not only cause discomfort and fatigue but can also decrease the absorption of the drug, increasing the risk of pregnancy. Nausea can persist and affect the daily life quality of the user.
  2. Menstrual Cycle and Weight Changes:
    • Variations in the Menstrual Cycle: Emergency contraception can cause sudden changes in a woman’s menstrual cycle. The cycle may become irregular, longer, or shorter, leading to instability and abnormalities.

    • Impact of Sudden Weight Gain: Some women may experience sudden weight gain after using emergency contraception. This weight gain is often due to water retention and affects the overall weight of the user.
  1. Mood Changes and Nutrient Supply Risks:
    • Mood Swings and Psychological Changes: Feelings of stress, sadness, or irritability are common mood changes after taking emergency contraception. Mood swings can affect social relationships and the mental well-being of the user.
    • Nutritional Imbalances and Health Impacts: Nutritional imbalance can occur when emergency contraception changes the process of nutrient absorption and utilization in the body. The risk to health, especially for women with unbalanced diets, may increase.

Health Risks

  1. Increased Blood Pressure and Cardiovascular/Stroking Risks:
    • Increased Risk of Hypertension: Some studies have indicated that using emergency contraception can increase the risk of hypertension in some women. The active ingredients in the medication can affect the vascular system and increase blood pressure.
    • Association with Stroke and Cardiovascular Risks: Increased blood pressure can raise the risk of stroke and cardiovascular problems. Those with a history of cardiovascular issues should be cautiously advised when using emergency contraception to avoid increased risk.
  2. Pregnancy Risk and Lack of Protection Against STIs:
    • Pregnancy Risk if Misused: Incorrect use of emergency contraception can increase the risk of pregnancy. Non-adherence to dosage or using beyond the recommended time can reduce the effectiveness of the medication.
    • Lack of Protection Against Sexually Transmitted Infections (STIs): Emergency contraception does not provide protection against sexually transmitted infections (STIs). Using this medication does not replace the need for STI protection measures like condoms. Users need to remain vigilant and take additional precautions to protect overall health

Consultation and Caution Before Use

Consultation by Physicians and Healthcare Professionals

    • Health Check and Diagnosis Process: Before deciding to use emergency contraception, undergoing a health check by a physician is a crucial step. Physicians will assess the medical history, past illnesses, and individual factors of the user to ensure the medication does not cause any adverse effects.

You should see your doctor for advice on use

    • Benefits of Professional Consultation in Facing Side Effects: Healthcare professionals can address any concerns about the side effects of emergency contraception and advise on specific considerations. Professional consultation helps users understand better how to manage side effects and choose other suitable contraceptive methods.

Use of Medical Devices and Medication as Directed:

    • Recommended Support Tools and Medications: Physicians may suggest using support devices such as anti-nausea wristbands or emergency contraception suction devices to reduce the risk of vomiting. Medications and devices must be carefully selected, suitable for the specific health condition and medical history of the user.
    • Safe and Effective Usage Methods: Detailed instructions on how to use the medication and devices, including dosage, timing, and other safety measures. Information on how to deal with possible side effects and when to seek professional medical help.

Several studies have been conducted to assess the effectiveness of emergency contraception. The results of these studies indicate that emergency contraception is effective in preventing unintended pregnancies within 72 hours after unprotected sexual intercourse.

  • A study published in The Lancet journal in 2009 showed that the effectiveness of a single-dose emergency contraceptive pill is 95% if used within 24 hours after unprotected sex, 85% if used within 48 hours, and 58% if used within 72 hours.
  • Another study published in the Journal of the American Medical Association in 2010 showed that the effectiveness of a two-dose emergency contraceptive pill is 98% if used within 24 hours after unprotected sex, 87% if used within 48 hours, and 77% if used within 72 hours.
