How Oral Contraceptive Pills Work

OCP

At Complete Healthcare for Women, Dr. Richard Lorenzo, DO, and Kortney Jones, ARNP, are dedicated to providing comprehensive reproductive health care. 

 

Types of Oral Contraceptive Pills

There are two main types of oral contraceptive pills we prescribe: combination pills and progestin-only pills.

Combination Pills: These pills contain both estrogen and progestin. They are the most commonly prescribed type of oral contraceptive and come in various formulations, including monophasic, biphasic, and triphasic, which differ in hormone levels throughout the cycle.

Progestin-Only Pills (Mini-Pills): These contain only progestin and are suitable for women who cannot take estrogen. They require strict adherence to daily dosing to be effective.

Mechanism of Action

Oral contraceptive pills prevent pregnancy through several mechanisms:

1. Inhibition of Ovulation:

2. Thickening Cervical Mucus:

3. Thinning the Endometrial Lining:

Starting Oral Contraceptive Pills

Starting oral contraceptive pills typically involves a consultation with one of our healthcare providers, who will assess your health, medical history, and preferences to determine the best type of pill for you.

Combination Pills:

Progestin-Only Pills:

Effectiveness and Adherence

The effectiveness of oral contraceptive pills depends on adherence to the prescribed regimen. Combination pills are about 99% effective with perfect use but around 91% effective with typical use, which accounts for occasional missed pills. Progestin-only pills have similar effectiveness but require more stringent adherence to daily dosing.

Side Effects and Management

While many women tolerate oral contraceptives well, some may experience side effects such as nausea, breast tenderness, weight gain, mood changes, and spotting between periods. These side effects often subside after the first few months of use. If they persist or become bothersome, consulting with Dr. Richard Lorenzo, DO, or Kortney Jones, ARNP, is important. We may recommend a different formulation or another birth control method.

Filling Your Prescription

Filling your prescription involves several steps:

Regular Follow-Up

Regular follow-up appointments with Dr. Richard Lorenzo, DO, or Kortney Jones, ARNP, are crucial to ensure the chosen method is working well for you and to address any concerns or side effects. These appointments also provide an opportunity to discuss any changes in your health that might necessitate a change in your contraceptive method.

Conclusion

Oral contraceptive pills are a reliable and widely used method of birth control that work through the prevention of ovulation, thickening of cervical mucus, and thinning of the uterine lining. Adherence to the prescribed regimen and regular consultations with our healthcare providers are key to maximizing their effectiveness and managing any side effects. Always consult with Dr. Richard Lorenzo, DO, or Kortney Jones, ARNP, to determine the best contraceptive method for your individual needs and ensure you have the appropriate support and follow-up care.
