| drug name | Combination Oral Contraceptives (COCs) |
| classification | Hormonal Contraceptives |
| pharmacokinetics | COCs contain estrogen and progestin, which are absorbed through the gastrointestinal tract. The hormones circulate in the bloodstream, suppressing ovulation and thickening cervical mucus. Elimination is primarily through metabolism in the liver, with some excretion in the urine. The exact pharmacokinetic profile can vary based on the specific COC formulation. |
| suggested dosage | Dosage varies significantly based on the specific COC formulation. Always follow the instructions provided by the prescribing physician or pharmacist. Typical regimens involve taking one pill daily at the same time, usually for 21 days followed by a 7-day placebo/sugar pill interval. The exact regimen should be determined in consultation with a medical provider. |
| indications | Combination oral contraceptives are primarily used for:
* **Birth control:** Preventing pregnancy
* **Menstrual cycle regulation:** Managing irregular periods and reducing painful periods
* **Reducing symptoms of premenstrual syndrome (PMS):** Reducing cramping, mood swings, and other symptoms associated with PMS
* **Treating some types of acne and hirsutism.**
* **Reducing ovarian cysts.** |
| safety in pregnancy | **Absolutely contraindicated** during pregnancy. If pregnancy occurs while using COCs, discontinuation is essential. |
| safety in breastfeeding | Generally safe for breastfeeding women, although some formulations may slightly reduce breast milk production. Individual considerations and physician consultation are crucial. |
| side effects | Common side effects can include:
* **Nausea, vomiting, or breast tenderness**
* **Headaches or dizziness**
* **Mood changes**
* **Changes in menstrual bleeding patterns (e.g., spotting or breakthrough bleeding)**
* **Weight changes (though often minimal)**
* **Fluid retention**
* **Rarely, serious side effects, such as blood clots, stroke, heart attack, or liver problems.** This risk is higher in smokers, women over 35, and those with certain pre-existing conditions. |

| interactions | Certain medications (e.g., some antibiotics, anticonvulsants, and others) can decrease the effectiveness of COCs. Consultation with a physician or pharmacist about potential interactions is important. |
| warnings and precautions | Regular checkups are essential while using COCs, including blood pressure and other relevant health measures, especially if there is a family history of certain diseases. Always inform your physician of any medical history and any medications you are taking. |
| additional information | | 1 | Individual responses to COCs can vary. Consulting a doctor for personalized advice is crucial. | | 2 | Smoking significantly increases the risk of cardiovascular complications with COCs, particularly in older women. | | 3 | COCs do not protect against sexually transmitted infections. | | 4 | Regular follow-up with a physician is recommended throughout the use of COCs to monitor efficacy and potential side effects. |
