Keriette Diario (Ethinylestradiol, Levonorgestrel | Lactose Anhydrous)

Keriette Diario, a combined oral contraceptive, works within the hormonal reproductive pathway to prevent unintended pregnancy.

• Prevention of pregnancy: provides reliable contraceptive protection for women of childbearing potential.
• Management of menstrual cycle irregularities: helps regulate cycle length and reduce heavy bleeding.
• Treatment of moderate acne: reduces androgen‑driven skin lesions in women using hormonal regulation.

• Ethinylestradiol and levonorgestrel act synergistically to suppress the hypothalamic‑pituitary‑ovarian axis, preventing the mid‑cycle surge of luteinizing hormone and thereby inhibiting ovulation. The estrogen component stabilizes the endometrial lining, while the progestin thickens cervical mucus and induces endometrial changes that diminish sperm penetration and implantation potential.

Keriette Diario may cause a range of adverse reactions, varying in frequency and severity.

Common Side Effects

• Nausea: mild to moderate stomach upset.
• Breast tenderness: discomfort or swelling of the breasts.
• Headache: transient cranial pain.
• Weight gain: slight increase in body weight.
• Mood changes: irritability or emotional fluctuations.
• Breakthrough bleeding: spotting between periods.

Serious or Rare Side Effects

• Venous thromboembolism: blood clots in deep veins or lungs.
• Arterial thrombosis: clot formation in arteries leading to stroke or heart attack.
• Hypertension: significant increase in blood pressure.
• Liver tumor: benign hepatic adenoma development.
• Gallbladder disease: formation of gallstones or inflammation.
• Severe allergic reaction: anaphylaxis with rash, swelling, or breathing difficulty.

Before prescribing Keriette Diario, clinicians should consider several safety precautions.

• Contraindication in pregnancy: the product must not be used by pregnant women.
• Smoking over age 35: avoid use in women who smoke heavily due to increased cardiovascular risk.
• Cardiovascular assessment: evaluate history of thromboembolic disorders before initiation.
• Blood pressure monitoring: check and control hypertension during therapy.
• Hepatic function review: assess liver disease as the drug is metabolized hepatically.
• Store at room temperature: keep tablets in the original packaging, protect from moisture and light.

Keriette Diario can interact with other medicines, altering its effectiveness or safety.

Major Interactions (Avoid)

• Enzyme‑inducing anticonvulsants (e.g., carbamazepine, phenytoin): reduce contraceptive efficacy.
• Rifampicin and other strong antibiotics: decrease hormone levels, risking breakthrough ovulation.
• St. John's wort: herbal inducer that lowers oral contraceptive plasma concentrations.
• HIV protease inhibitors (e.g., ritonavir): may increase hormone exposure and side‑effect risk.
• Certain antiretrovirals (e.g., efavirenz): diminish contraceptive reliability.

Moderate Interactions (Monitor Closely)

• Antifungal agents (e.g., ketoconazole): may increase hormone levels, requiring monitoring.
• Selective serotonin reuptake inhibitors: possible modest increase in side‑effects.
• Antihypertensive drugs (e.g., beta‑blockers): monitor blood pressure changes.
• Antiemetics (e.g., metoclopramide): may affect hormone metabolism.
• Herbal supplements (e.g., ginseng): potential to alter contraceptive effectiveness.
