Levosolo (Levonorgestrel)

Levosolo (levonorgestrel) is a progestogen used in the reproductive health pathway for emergency contraception.

• Emergency contraception: prevents pregnancy after unprotected sex when taken within the approved time window.
• Post‑coital pregnancy prevention: provides a single‑dose option to reduce the risk of conception.
• Hormonal contraception component: may be included in combined oral contraceptive regimens for regular cycle control.

• Levonorgestrel binds to progesterone receptors in the hypothalamus and pituitary, suppressing the luteinizing hormone surge and thereby inhibiting or delaying ovulation. It also induces changes in the endometrial lining that reduce its receptivity to a fertilized egg, decreasing the likelihood of implantation.

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

Common Side Effects

• Nausea: mild to moderate stomach upset.
• Abdominal pain or cramps: discomfort in the lower abdomen.
• Fatigue: feeling unusually tired.
• Headache: mild to moderate head pain.
• Dizziness: sensation of light‑headedness.
• Menstrual changes: spotting or altered timing of the next period.

Serious or Rare Side Effects

• Severe allergic reaction (anaphylaxis): difficulty breathing, swelling of face or throat.
• Chest pain or palpitations: may indicate cardiac involvement.
• Persistent vomiting or vomiting blood: requires immediate medical attention.
• Severe abdominal pain: could signal ectopic pregnancy.
• Thrombosis: rare clot formation in veins or arteries.

Before using Levosolo, consider the following safety measures.

• Timing of intercourse: ensure the product is taken within the recommended window after unprotected sex.
• Medical history review: disclose any history of hormonal disorders, liver disease, or clotting disorders.
• Pregnancy status: avoid use if already pregnant; consult a healthcare professional.
• Concomitant medications: inform the prescriber about enzyme‑inducing drugs that may reduce effectiveness.
• Keep out of reach of children: store securely to prevent accidental ingestion.
• Store at ambient temperature: keep in the original pack, protect from moisture and direct sunlight.

Levosolo can interact with other medicines, affecting its efficacy or safety.

Major Interactions (Avoid)

• Rifampin: strong enzyme inducer that markedly reduces levonorgestrel levels.
• St. John’s wort: herbal inducer that may lower contraceptive effectiveness.
• Anticonvulsants (phenytoin, carbamazepine): increase metabolism of levonorgestrel.
• Griseofulvin: reduces plasma concentrations of levonorgestrel.

Moderate Interactions (Monitor Closely)

• Azole antifungals (ketoconazole, itraconazole): may increase levonorgestrel exposure.
• Antiretrovirals (efavirenz): can lower effectiveness of levonorgestrel.
• Combined hormonal contraceptives: concurrent use may require dosage adjustment or alternative methods.
