🩺 Quick Clinical Answer

Unwanted-72 and i-Pill contain high-dose Levonorgestrel (1.5mg), a synthetic progestin. It prevents unintended pregnancy by inhibiting or delaying ovulation and thickening cervical mucus. It is NOT an abortion pill and will NOT terminate an already implanted pregnancy. It must be taken as soon as possible within 72 hours of unprotected intercourse for maximum efficacy.

1. Time-Sensitive Efficacy (The 72-Hour Window)

Efficacy is highest (approx. 95%) when taken within the first 24 hours. Efficacy drops to 85% between 24 and 48 hours, and to 58% between 48 and 72 hours. Beyond 72 hours, oral levonorgestrel is largely ineffective.

2. Expected Side Effects & Cycle Irregularities

High-dose progestin commonly triggers nausea, vomiting, breast tenderness, and lower abdominal cramping. Irregular withdrawal bleeding or spotting often occurs 5 to 7 days after the pill, and your subsequent menstrual period may arrive a few days earlier or later than usual.

3. Why It Must Never Replace Regular Contraception

Emergency contraceptive pills are designed exclusively for emergency backup (e.g. condom breakage). Frequent repeated use disrupts hormonal feedback loops, causing severe menstrual irregularities. It offers zero protection against sexually transmitted infections (STIs).

Frequently Asked Questions (Clinical & Regulatory)

Q1: What if I vomit within 2 hours of swallowing Unwanted-72?

If vomiting occurs within 2 hours of ingestion, the pill was likely not absorbed. You must take another replacement tablet immediately.

Q2: Does the morning-after pill harm future fertility?

No, clinical studies confirm that emergency levonorgestrel has no negative impact on long-term fertility or future pregnancies.

Q3: Why is periconceptional Folic Acid supplementation critical for neural tube defect prevention?

Folic acid (400–500 mcg daily) is required during the first 28 days post-conception—often before pregnancy is confirmed—for neural tube closure. Prophylactic supplementation reduces the incidence of anencephaly and spina bifida by up to 70%.

Q4: Why must pediatric dosages never be estimated by breaking adult tablets?

Children possess immature hepatic microsomal enzyme pathways, higher total body water ratios, and evolving renal clearance. Pediatric doses must be calculated precisely on a milligram-per-kilogram body weight basis (mg/kg/dose) using oral dosing syringes.

Q5: Are Jan Aushadhi generic pediatric syrups and oral rehydration salts safe for infants?

Yes. PMBJP Jan Aushadhi Paracetamol pediatric suspensions, Zinc gluconate solutions, and low-osmolarity WHO-formula ORS adhere to strict purity criteria and provide affordable, life-saving pediatric rehydration.
