Isteranda

Levonorgestrel, the active ingredient in Isteranda, is a progestogen presented as an oral tablet for oral use. It is used to prevent pregnancy after unprotected sexual intercourse or contraceptive failure. GNH USA supplies Isteranda as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Levonorgestrel is a progestogen used in emergency contraception to prevent pregnancy after unprotected sexual activity. - Unprotected intercourse: prevents pregnancy when taken promptly after exposure. - Contraceptive failure: provides backup when a regular contraceptive method is missed or ineffective. - Emergency contraception: reduces the risk of implantation when administered within the approved time window.

Levonorgestrel 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. - Headache: occasional tension‑type headache. - Dizziness: brief episodes of light‑headedness. - Fatigue: feeling unusually tired. - Menstrual changes: spotting or altered timing of the next period.

Serious or Rare Side Effects: - Severe allergic reaction: rash, swelling, or difficulty breathing. - Chest pain or palpitations: may indicate cardiovascular involvement. - Severe abdominal pain: could signal ectopic pregnancy. - Liver dysfunction: jaundice or abnormal liver tests. - Thrombosis: rare clotting events. - Persistent vomiting: may require medical attention.

Before using Isteranda, consider the following safety measures. - Timing of intake: take as soon as possible after the event, ideally within 72 hours. - Drug interactions: avoid concomitant use of enzyme‑inducing medicines that may lower effectiveness. - Medical conditions: consult a healthcare professional if you have liver disease or hormonal disorders. - Pregnancy status: do not use if you are already pregnant; it will not terminate an existing pregnancy. - Breastfeeding: discuss potential risks with a clinician before use. - Store at ambient temperature: keep in the original packaging, protect from moisture and excessive heat.

Levonorgestrel can interact with other medicines that affect hormone metabolism.

Major Interactions (Avoid): - Rifampicin: significantly reduces contraceptive efficacy. - Enzyme‑inducing antiepileptics (phenytoin, carbamazepine): lower levonorgestrel levels. - St. John’s Wort: may decrease effectiveness.

Moderate Interactions (Monitor Closely): - Azole antifungals (ketoconazole): can increase levonorgestrel concentrations. - Protease inhibitor antiretrovirals: potential pharmacokinetic interaction. - Combined hormonal contraceptives: may alter overall hormonal balance; monitor for reduced efficacy.
