Postinor-2 0.75毫克片剂

介绍

Postinor 2 Tablet is a trusted emergency contraceptive used to help prevent unplanned pregnancy after unprotected sex or contraceptive failure (such as a broken condom). It contains levonorgestrel, a synthetic hormone commonly used in birth control medications. When taken within the recommended time frame—ideally within 72 hours—it works by preventing or delaying ovulation and may also interfere with fertilization or implantation. It is not intended for routine contraception but offers a reliable backup option during unexpected situations.

Designed for single-use emergency scenarios, Postinor-2 provides peace of mind when conventional contraceptive methods fail. Most users tolerate it well, with a safety profile supported by decades of clinical experience. Common side effects include mild nausea, fatigue, slight menstrual irregularities, and occasional lower abdominal pain. It is not an abortion pill and will not terminate an existing pregnancy. DoctorOnCall International provides genuine Postinor-2, dispensed by licensed Malaysian pharmacists for worldwide customers.

一般适应症

Postinor-2 is prescribed for post-coital contraception only, specifically to reduce pregnancy risk following unprotected intercourse, contraceptive failure, or missed birth control pills. It works by preventing ovulation, disrupting typical fertilization timing. Though intended for single-use emergency protection, it is valuable in real-life scenarios, including travel, unexpected sexual activity, or confirmed condom failure.

Global consumers trust DoctorOnCall International for verified sourcing, quality oversight, and pharmacist support. Postinor-2 is not suitable for routine contraception and should not replace long-term contraceptive planning.

How to Take Postinor-2

Postinor-2 comes in a blister pack with two 0.75 mg tablets. Take the first tablet as soon as possible after unprotected sex—ideally within 12 hours and no later than 72 hours. Take the second tablet exactly 12 hours after the first. Taking both doses earlier improves effectiveness.

Tablets may be taken with or without food; if nausea occurs, take with a light meal or snack. Drink plenty of water and avoid lying down immediately after swallowing. If vomiting occurs within 2 hours, consult your doctor—it may be necessary to repeat the dose. Never take extra tablets unless instructed.

剂量信息

Each tablet contains 0.75 mg levonorgestrel. Standard dosage: two tablets total—first immediately, second 12 hours later. Alternatively, both tablets may sometimes be prescribed together as a single 1.5 mg dose, depending on medical advice.

Follow your healthcare provider’s guidance. Self-medication, repeated use in the same cycle, or long-term use is not advised, as it may cause hormonal disruption and menstrual irregularities.

保质期

Postinor-2 typically has a shelf life of 3 years from the manufacturing date. Always check the expiration date on your packaging.
