Consumer information: Min-Ovral®

What is Min-Ovral Used For?

  • Min-Ovral® is a combination oral contraceptive (COC) used to prevent pregnancy.
  • It contains levonorgestrel (a progestin) and ethinyl estradiol (an estrogen).

How Does Min-Ovral Work?

  • Prevents ovulation: It stops the release of an egg from the ovary.
  • Thickens cervical mucus: Makes it difficult for sperm to reach the egg.
  • Alters the uterine lining: Reduces the likelihood of implantation of a fertilized egg.

Effectiveness:

  • Perfect use: When taken exactly as directed, Min-Ovral is more than 99% effective at preventing pregnancy.
  • Typical use: With missed or late pills, the effectiveness may decrease slightly.
  • Min-Ovral does not protect against sexually transmitted infections (STIs). Use condoms for protection against STIs.

Who Should Not Use Min-Ovral?

  • Pregnant women or those who suspect pregnancy.
  • Women with a history of or current blood clots, heart attack, stroke, or liver disease.
  • Those with breast cancer or estrogen-dependent tumors.
  • Women with undiagnosed abnormal vaginal bleeding, severe high blood pressure, or diabetes with vascular complications.

Warnings and Precautions:

  • Smoking significantly increases the risk of serious cardiovascular side effects, especially in women over 35.
  • There is an increased risk of blood clots, stroke, and heart attack, particularly in women with risk factors such as obesity, hypertension, and diabetes.
  • Liver disease: Use is contraindicated in women with active liver disease or abnormal liver function testing.
  • Women on certain Hepatitis C medications should avoid using Min-Ovral due to potential interactions.

Possible Side Effects:

  • Common side effects include:
    • Nausea, vomiting, and headaches.
    • Irregular bleeding or spotting between periods.
    • Breast tenderness or enlargement.
    • Weight changes and mood changes.
  • Serious side effects (less common):
    • Blood clots (deep vein thrombosis, pulmonary embolism).
    • Stroke or heart attack.
    • Liver tumors.
