Effective medicines for preventing pregnancy include hormonal contraceptives such as combined oral contraceptive pills (containing estrogen and progestin), progestin-only pills, and long-acting options like hormonal implants and injectable contraceptives. These medicines work by preventing ovulation (release of eggs) and altering the uterine environment to block sperm entry. It is advisable to consult a gynaecologist to choose the most suitable option based on your health condition and lifestyle.

The Unwanted-72 tablet is an emergency contraceptive used after unprotected sex or contraceptive failure. It should be taken as soon as possible, ideally within 72 hours (3 days) after intercourse, with maximum effectiveness within the first 24 hours. It works by delaying ovulation and may also prevent implantation. It is not for regular contraception and does not protect against sexually transmitted infections.
