The likely reference: Levonorgestrel emergency contraception
The name 'maple Forte' does not correspond to any recognized pharmaceutical product, and there is no company named 'Maple Pharma' that produces an emergency contraceptive under this name. The repeated association of the search query with results for levonorgestrel emergency contraception suggests a common misunderstanding or a misspelled version of a similar-sounding product. This article focuses on providing accurate information about levonorgestrel 1.5mg tablets, the most probable subject of the search query.
What is levonorgestrel?
Levonorgestrel is a synthetic hormone known as a progestin. As a medication, it is used in two primary forms: a low-dose version for regular hormonal birth control and a high-dose version for emergency contraception. The product most often confused with 'maple Forte' is the single-tablet, 1.5mg dose of levonorgestrel, often referred to as the 'morning-after pill'.
How levonorgestrel works as emergency contraception
Levonorgestrel works mainly by preventing or delaying the release of an egg from the ovary (ovulation). It is most effective the sooner it is taken after unprotected sex. For maximum efficacy, the tablet should be taken within 72 hours (3 days) of the event. Some sources suggest it may also work by preventing the fertilization of an egg or the attachment of a fertilized egg to the uterine wall (implantation), though the primary mechanism is delaying ovulation. It is important to note that levonorgestrel will not terminate an existing pregnancy.
Important usage information
- Timeliness is Key: The effectiveness of levonorgestrel significantly decreases with each day that passes after unprotected sex. While the 72-hour window is the standard recommendation, earlier is always better.
- Dosage: For emergency contraception, the dose is a single 1.5 mg tablet, taken orally.
- Vomiting: If you vomit within two hours of taking the tablet, contact a healthcare professional, as you may need to take another dose.
- Not for Regular Use: Levonorgestrel is a backup method and is not a substitute for regular birth control. It is less effective than daily contraception.
Potential side effects
Many women experience side effects after taking levonorgestrel due to the high hormone dose. These usually subside within a few days.
Common side effects include:
- Nausea and vomiting
- Headaches and dizziness
- Breast tenderness
- Stomach or abdominal pain
- Fatigue
- Changes to menstrual bleeding (heavier, lighter, or irregular periods)
When to seek immediate medical attention: If your next period is more than a week late or you experience severe lower abdominal pain, you should take a pregnancy test and consult a healthcare provider. Severe abdominal pain could be a symptom of an ectopic pregnancy, a rare but serious condition.
Contraindications and drug interactions
Levonorgestrel is not suitable for everyone and can interact with certain medications. It is crucial to consult a doctor or pharmacist, especially if you have existing health conditions or take other medicines.
Key contraindications:
- A known allergy to levonorgestrel or any other component of the tablet.
- Already being pregnant, as it will not work.
- History of active thromboembolic disorders or severe liver disease.
Significant drug interactions: Certain medications and supplements can reduce the effectiveness of levonorgestrel, including:
- Certain HIV medications, such as efavirenz.
- Rifampin, used for tuberculosis.
- Medications for seizures (epilepsy).
- Herbal supplements, such as St. John's wort.
Comparison of emergency contraceptive options
For individuals considering emergency contraception, it's important to be aware of the options available and their differences in effectiveness and timing. While levonorgestrel is a popular and widely accessible option, other choices may be more suitable depending on the situation. Here is a comparison:

| Weight Impact | Less effective in individuals with a higher body weight. | More effective than levonorgestrel in individuals with a higher body weight, up to 195 lbs. | No known impact on effectiveness due to body weight. |

Conclusion
In summary, the pill referred to as 'maple Forte' is not a recognized drug brand. The term is likely a misidentification for a common medication, most likely levonorgestrel-based emergency contraception. Levonorgestrel is a progestin taken within 72 hours after unprotected sex to prevent pregnancy, primarily by inhibiting ovulation. While it is widely available over-the-counter and can be an effective backup method, it is not for regular use. Individuals considering emergency contraception should understand the different options available, their varying effectiveness windows, and how they may be affected by factors such as body weight. Always consult with a healthcare provider to ensure you are selecting the safest and most appropriate option for your situation.
