Postinor 1 and Postinor 2 are two commonly used emergency contraceptive pills that contain the hormone levonorgestrel. While both pills are effective in preventing pregnancy, they are different in terms of their dosage and regimen.
Emergency contraceptive pills (ECPs) contain synthetic hormones that prevent or delay ovulation, which is the release of an egg from the ovary.
What are Postinor 1 and Postinor 2?
Postinor 1 and Postinor 2 are emergency contraceptive pills that are used to prevent pregnancy after unprotected sex or contraceptive failure.
They contain the hormone levonorgestrel, which is a synthetic form of the hormone progesterone. Levonorgestrel works by preventing or delaying ovulation, which is the release of an egg from the ovary. This makes it more difficult for sperm to fertilize an egg and prevents pregnancy.
What is the Difference between Postinor 1 and Postinor 2?
The main difference between Postinor 1 and Postinor 2 is the dosage and regimen.
| postinor 1 | Postinor 2 |
|---|---|
| Postinor 1 contains a single pill that contains 1.5 milligrams of levonorgestrel. | Postinor 2, on the other hand, contains two pills, each containing 0.75 milligrams of levonorgestrel. |
| Postinor 1 is most effective when taken within the first 24 hours after unprotected sex, and the effectiveness decreases over time. | Postinor 2 is also most effective when taken within the first 24 hours after unprotected sex. It works by preventing or delaying ovulation, just like Postinor 1. |
| It is taken as a single dose within 72 hours of unprotected sex. | The first pill is taken within 72 hours of unprotected sex, and the second pill is taken 12 hours later. |
| It works by preventing or delaying ovulation, which is the release of an egg from the ovary. | It works by preventing or delaying ovulation, just like Postinor 1. |
Studies have shown that Postinor 1 is slightly more effective than Postinor 2 in preventing pregnancy when taken within the first 24 hours after unprotected sex. However, both pills are highly effective in preventing pregnancy when taken as directed.
Side Effects of Postinor 1 and Postinor 2
Both contraceptives are generally safe and well-tolerated. However, like all medications, they can have side effects. The most common side effects of both pills include:
- Nausea
- Vomiting
- Abdominal pain or cramps
- Fatigue
- Dizziness
- Headache
These side effects are usually mild and resolve within a few days. However, if you experience severe or persistent side effects, you should contact your healthcare provider.
Alternatives
There are other alternatives if you are looking for a different contraceptive. These pills contain levonorgestrel, which is the same hormone found in Postinor1 and Postinor 2. Some alternatives include:
- Plan B One-Step: This emergency contraceptive pill contains 1.5 milligrams of levonorgestrel, just like Postinor 1. It is taken as a single dose within 72 hours of unprotected sex.
- Ella: This emergency contraceptive pill contains the hormone ulipristal acetate, which works by preventing or delaying ovulation. It is taken as a single dose within 120 hours (five days) of unprotected sex.
- Copper Intrauterine Device (IUD): This is a long-acting reversible contraceptive that can also be used as emergency contraception. It is a small T-shaped device that is inserted into the uterus by a healthcare provider. The copper in the device acts as a spermicide and prevents fertilization.
It is important to talk to your healthcare provider to determine which emergency contraceptive pill or method is right for you. They can guide when and how to take the medication, as well as information on possible side effects and interactions with other medications.
Conclusion
Postinor 1 and Postinor 2 are both emergency contraceptive pills that are used to prevent pregnancy after unprotected sex or contraceptive failure. While they both contain the hormone levonorgestrel and work by preventing or delaying ovulation, they differ in terms of their dosage and regimen. Postinor 1 is a single pill taken within 72 hours of unprotected sex, while Postinor 2 is two pills taken 12 hours apart within 72 hours of unprotected sex.
It is important to note that emergency contraceptive pills are not recommended as a regular form of birth control and do not protect against sexually transmitted infections (STIs). In addition, both Postinor 1 and Postinor 2 can have side effects, although they are usually mild and resolve within a few days. If you experience severe or persistent side effects, you should contact your healthcare provider.
