Leverette (Ethinylestradiol, Levonorgestrel | Lactose)

Leverette is a combined hormonal contraceptive that acts on the reproductive endocrine system to prevent pregnancy.

• Contraception: provides reliable prevention of pregnancy for women of child‑bearing potential.
• Menstrual cycle regulation: helps achieve more predictable menstrual bleeding patterns.
• Ovarian cyst management: reduces the formation of functional ovarian cysts.

• Ethinylestradiol and levonorgestrel work together to suppress the hypothalamic‑pituitary‑ovarian axis, inhibiting the mid‑cycle surge of luteinising hormone and preventing ovulation. The estrogen component stabilises the endometrial lining, while the progestogen thickens cervical mucus and alters the endometrium, creating an environment hostile to sperm penetration and implantation.

Leverette may cause a range of adverse reactions, most of which are mild and transient.

Common Side Effects

• Nausea: mild to moderate stomach upset, especially during the first cycles.
• Breast tenderness: temporary swelling or discomfort of the breasts.
• Headache: occasional tension‑type or migraine‑like headaches.
• Weight gain: slight increase in body weight due to fluid retention.
• Mood changes: mild fluctuations in mood or irritability.

Serious or Rare Side Effects

• Thromboembolic events: deep vein thrombosis or pulmonary embolism, requiring immediate medical attention.
• Stroke or myocardial infarction: rare but severe vascular events, especially in high‑risk individuals.
• Severe allergic reaction: rash, swelling, or anaphylaxis.
• Hepatic adenoma: benign liver tumor associated with long‑term use.
• Visual disturbances: sudden changes in vision that should be evaluated promptly.

Before prescribing Leverette, clinicians should assess individual risk factors and counsel patients on safe use.

• Assess thromboembolic risk: review personal and family history of clotting disorders.
• Avoid in smokers over 35: smoking markedly increases cardiovascular risk.
• Evaluate hepatic function: monitor liver disease or dysfunction.
• Review concomitant medications: consider potential drug interactions that may affect efficacy.
• Store at ambient temperature: keep in the original pack, protect from moisture and direct sunlight.

Leverette can interact with several medicines, altering its contraceptive effectiveness or increasing adverse effects.

Major Interactions (Avoid)

• Enzyme‑inducing anticonvulsants (e.g., carbamazepine, phenytoin): may markedly reduce hormone levels.
• Rifampin or other rifamycins: decrease plasma concentrations of both estrogen and progestogen.
• St. John's wort: herbal inducer that can lower contraceptive efficacy.

Moderate Interactions (Monitor Closely)

• Antifungal agents (e.g., ketoconazole, itraconazole): may increase hormone levels and risk of side effects.
• Macrolide antibiotics (e.g., erythromycin, clarithromycin): can raise plasma concentrations modestly.
• Selective serotonin reuptake inhibitors (e.g., fluoxetine): may increase bleeding tendency when combined with NSAIDs.
