Levonorgestrel Exeltis (Levonorgestrel)

Levonorgestrel Exeltis is a progestin‑based hormonal agent used in contraception and related pathways.

• Emergency contraception: provides a high‑dose regimen to prevent pregnancy after unprotected intercourse.
• Regular contraception: incorporated into daily oral regimens to inhibit ovulation and maintain contraceptive efficacy.
• Menstrual cycle regulation: may be used under medical supervision to adjust cycle timing and reduce heavy bleeding.

• Levonorgestrel binds to progesterone receptors in the hypothalamus and pituitary, suppressing the luteinizing hormone surge required for ovulation. It also thickens cervical mucus, creating a barrier to sperm penetration, and alters endometrial development, reducing the likelihood of implantation.

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

Common Side Effects

• Nausea or vomiting
• Headache
• Breast tenderness
• Irregular bleeding or spotting
• Mood changes

Before using Levonorgestrel Exeltis, consider the following safety measures.

• Contraindications: Do not use if you have a known hypersensitivity to levonorgestrel or any excipients.
• Pregnancy: Avoid use if you are already pregnant; the product is intended for prevention, not termination.
• Breastfeeding: Consult a healthcare professional before use while nursing.
• Drug interactions: Review concomitant medications that may reduce efficacy.
• Medical conditions: Use caution in patients with liver disease, uncontrolled hypertension, or clotting disorders.
• Store at ambient temperature: Keep below 25 °C, in the original packaging, protected from moisture and direct sunlight.

Levonorgestrel Exeltis can interact with other medicines, affecting its contraceptive effectiveness.

Major Interactions (Avoid)

• Enzyme inducers (e.g., rifampicin, carbamazepine, phenytoin): may markedly reduce plasma levels.
• Certain antiretrovirals (e.g., efavirenz): can decrease efficacy.

Moderate Interactions (Monitor Closely)

• Antifungal agents (e.g., ketoconazole): may increase levonorgestrel concentrations.
• St. John’s wort: may lower effectiveness.
• Anticonvulsants with moderate enzyme induction (e.g., phenobarbital): require monitoring.
• Herbal supplements affecting hormone metabolism: advise patient to discuss use.
