Combined Oral Contraceptives: Advantages, Disadvantages, and Risks

As a family physician and medical director of French origin, having completed my studies and practiced in France before settling in Quebec, it is essential for me to inform my patients about the different contraception options available. Combined oral contraceptives (estrogen-progestogen), often called combined pills, are a widely used method of contraception. This article aims to explain their advantages, disadvantages, and associated risks.

Advantages of Combined Oral Contraceptives

1. Effectiveness: When used correctly, combined oral contraceptives are very effective at preventing pregnancy, with a failure rate of less than 1% per year.

2. Menstrual Cycle Regulation: They help regulate menstrual cycles, reducing menstrual pain and heavy bleeding.

3. Acne Reduction: For some women, these pills can help reduce acne by regulating the hormones responsible for excess sebum.

4. Prevention of Certain Diseases: Combined oral contraceptives can reduce the risk of ovarian and endometrial cancers, as well as ovarian cysts.

Disadvantages of Combined Oral Contraceptives

1. Side Effects: Some women may experience nausea, headaches, breast tenderness, or mood swings.

2. Daily Intake Requirement: To maintain their effectiveness, these pills must be taken daily at the same time, which can be restrictive for some women.

3. Drug Interactions: Certain medications can decrease the effectiveness of combined oral contraceptives, requiring increased vigilance.

4. Cost: Depending on the place of residence and the healthcare system, the cost of contraceptives may vary and may not always be covered by health insurance (such as RAMQ).

Associated Risks of Combined Oral Contraceptives

1. Side Effects: Some women may experience nausea, headaches, breast tenderness, or mood swings.

2. Daily Intake Requirement: To maintain their effectiveness, these pills must be taken daily almost at the same time, which can be restrictive for some women.

3. Drug Interactions: Certain medications can decrease the effectiveness of combined oral contraceptives, requiring increased vigilance.

4. Cost: Depending on the place of residence and the healthcare system, the cost of contraceptives may vary and may not always be covered by health insurance.

5. STI Protection: Combined oral contraceptives do not protect against sexually transmitted and blood-borne infections (STBBIs). Only condoms provide protection against STBBIs.

Associated Risks of Combined Oral Contraceptives

1. Venous Thrombosis: One of the most serious risks is the formation of blood clots, particularly in women who smoke or those with a family history of thrombosis.

2. Strokes and Heart Attacks: Although rare, combined oral contraceptives can increase the risk of stroke and heart attack, especially in women with other risk factors such as hypertension or poor blood circulation.

3. Breast Cancer: Some studies suggest a slight increase in the risk of breast cancer among users of combined oral contraceptives, although this risk seems to decrease after stopping the pill.

4. High Blood Pressure: The use of combined oral contraceptives can sometimes lead to an increase in blood pressure, requiring regular monitoring.

5. Hepatic Risks: The use of combined oral contraceptives may be associated with liver disorders, including an increase in liver enzymes, cholestatic jaundice and, in rare cases, benign or malignant liver tumours.
