I-Pill is an emergency contraceptive pill designed to prevent unintended pregnancy following unprotected intercourse or contraceptive failure. It contains Levonorgestrel, a synthetic progestin that works primarily by inhibiting ovulation, preventing fertilization, and altering the uterine lining to prevent implantation.
Key Features
- Active Ingredient: Levonorgestrel 1.5 mg
- Indications: Used for emergency contraception within 72 hours (3 days) after unprotected sex or contraceptive failure.
- Effectiveness: Prevents approximately 84% of expected pregnancies if taken within the recommended time frame.
Mechanism of Action
- Prevention of Ovulation: The primary mechanism is to delay or inhibit ovulation, which means no egg is available for fertilization.
- Alteration of Uterine Lining: It may also change the endometrial lining, making it less suitable for implantation if fertilization does occur.
Dosage and Administration
- Recommended Dosage: Take one tablet as soon as possible after unprotected intercourse, ideally within 12 hours, but no later than 72 hours.
- Administration Instructions: Swallow the tablet whole with water. It can be taken with or without food, but taking it with food may help reduce potential stomach upset.
Side Effects
Common side effects may include:
- Nausea or vomiting
- Fatigue
- Headaches
- Lower abdominal pain or cramping
- Dizziness
- Breast tenderness
- Irregular bleeding or spotting
Most side effects are temporary and should resolve within a few days. However, if vomiting occurs within two hours of taking the pill, it is advisable to consult a healthcare provider, as a second dose may be necessary.
Precautions and Warnings
- Not for Regular Use: I-Pill is intended for emergency use only and should not replace regular contraceptive methods.
- No Protection Against STIs: This medication does not protect against sexually transmitted infections (STIs), including HIV.
- Consultation Recommended: Women with existing health conditions (e.g., diabetes, hypertension) should consult a healthcare provider before use.
