Plan B

Plan B Mechanism:

Plan B functions as an emergency contraceptive primarily by preventing ovulation and altering the transport of sperm and/or ova within the reproductive tract. This medication is ineffective if a woman is already pregnant, as it does not disrupt an established implantation process. In addition to serving as a hormonal inhibitor, Plan B modifies the consistency of cervical mucus, making it thicker and more difficult for sperm to reach the egg. It also affects the endometrial lining, which may prevent the implantation of a fertilized egg.

Plan B Dose:

For optimal efficacy, Plan B should be taken orally as soon as possible, preferably within 72 hours after unprotected intercourse or a known contraceptive failure. This medication can be used at any time during the menstrual cycle, although its effectiveness decreases the longer the delay in taking the tablet. If vomiting occurs within two hours of ingestion, consideration should be given to retaking the dosage.

Plan B Drug Interactions:

Certain medications or herbal products that influence the enzymes metabolizing progestin may reduce the effectiveness of Plan B. These include:

• Barbiturates
• Bosentan
• Carbamazepine
• Felbamate
• Griseofulvin
• Oxcarbazepine
• Phenytoin
• Rifampin

Plan B Other Information:

Plan B serves as a valuable option for women who wish to avoid unplanned pregnancies after unprotected intercourse. While it provides an effective means of contraception following a single incident, it does not prevent future pregnancies. For optimal results, Plan B should be taken within 72 hours of unprotected sexual activity. This oral emergency contraceptive has garnered significant acclaim for its effectiveness in preventing unintended pregnancies.

Plan B Side Effects:

Plan B is generally considered safe for most women; however, it is advisable to discuss potential interactions with other medications. It is crucial not to take Plan B if already pregnant, as it will not terminate an existing pregnancy. Common side effects may include:

• Menstrual changes
• Breast tenderness
• Nausea
• Abdominal pain
• Headache
• Fatigue
• Dizziness
• Vomiting

If vomiting occurs within two hours after taking the medication, consult a healthcare professional to determine if a repeat dosage is necessary. Additionally, unexpected vaginal bleeding may occur, and menstrual cycles may be altered following the use of Plan B. If a period is not observed within three weeks, a pregnancy test is recommended to rule out pregnancy.
