Kelsee (Dienogest, Ethinylestradiol | Lactose)

Kelsee, a combined oral contraceptive, is indicated for hormonal contraception.

• Prevention of pregnancy: provides reliable contraceptive protection for women of reproductive age.
• Regulation of menstrual cycle: helps achieve more predictable bleeding patterns.
• Reduction of ovarian cyst formation: lowers the incidence of functional ovarian cysts in users.

• Dienogest and ethinylestradiol act synergistically to suppress the mid‑cycle surge of luteinising hormone (LH) and follicle‑stimulating hormone (FSH), thereby inhibiting ovulation. The estrogen component stabilises the endometrium and increases cervical mucus viscosity, creating an environment hostile to sperm penetration and implantation.

Kelsee may cause a range of adverse reactions. Patients should be informed of both common and serious possibilities.

Common Side Effects

• Nausea: mild to moderate stomach upset.
• Breast tenderness: temporary swelling or discomfort.
• Headache: often transient and mild.
• Breakthrough bleeding: irregular spotting between periods.
• Mood changes: occasional irritability or mood swings.

Serious or Rare Side Effects

• Venous thromboembolism: deep‑vein clot or pulmonary embolism.
• Arterial thrombosis: stroke or myocardial infarction.
• Severe hypertension: sudden rise in blood pressure.
• Liver tumor: benign hepatic adenoma.
• Allergic reaction: rash, swelling, or anaphylaxis.

Before prescribing Kelsee, clinicians should evaluate several safety considerations.

• Assess cardiovascular risk: review history of thrombosis or clotting disorders.
• Avoid in smokers over 35 years: smoking markedly increases thrombotic risk.
• Consider liver function: contraindicated in active liver disease or severe hepatic impairment.
• Monitor blood pressure: oral contraceptives may elevate systolic and diastolic values.
• Review concomitant medications: potential interactions can affect efficacy.
• Store at ambient temperature: keep in the original packaging, protect from moisture and direct sunlight.

Kelsee can interact with other medicines, altering its effectiveness or safety profile.

Major Interactions (Avoid)

• Enzyme‑inducing anticonvulsants (e.g., carbamazepine, phenytoin): may markedly reduce hormone levels.
• Rifampin (antibiotic): can decrease contraceptive efficacy.
• Certain protease inhibitors (e.g., ritonavir): may increase hormone concentrations and risk of side effects.

Moderate Interactions (Monitor Closely)

• St. John’s wort: may lower effectiveness through enzyme induction.
• Antifungals such as ketoconazole: can raise hormone levels, requiring monitoring.
• Diuretics: may affect fluid balance and blood pressure, necessitating observation.
