| drug name | Combined Hormonal Contraceptives |
| classification | Hormonal Contraceptives (estrogen-progestin combination) |
| pharmacokinetics | Oral combined hormonal contraceptives (OCs) are absorbed rapidly from the gastrointestinal tract. Peak plasma concentrations are typically reached within 1-2 hours. The primary route of elimination is via metabolism in the liver, with subsequent excretion in the urine and feces. The half-life of the individual components (estrogen and progestin) can vary depending on the specific formulation. There is significant inter-individual variability in absorption and metabolism, which can affect efficacy and require individualization of dosage in some cases. It's also important to note that food can affect the rate of absorption but not the extent of absorption. |
| suggested dosage | Dosage varies significantly depending on the specific formulation of combined hormonal contraceptive. Consult with a healthcare professional to determine the appropriate regimen. Generic formulations may exist, but it's vital to discuss the particular product with your doctor for safety and efficacy. |
| indications | Primary use is for contraception. May also be used for managing menstrual irregularities, acne, hirsutism, and premenstrual syndrome (PMS). |
| safety in pregnancy | Absolutely contraindicated if pregnancy is confirmed or suspected. If a woman misses taking a pill and then becomes pregnant, the potential impact on the developing fetus needs thorough consideration and discussion with a doctor. |
| safety in breastfeeding | Generally considered safe during breastfeeding, but some formulations might alter milk production or composition. A healthcare professional can advise on appropriate choice and monitoring, particularly in the initial postpartum period. Potential effects on breastfeeding infant should be assessed. |
