Lefisyo

Levomethadone Hydrochloride, the active ingredient in Lefisyo, is an opioid agonist presented as an oral dosage form for oral use. It is used in the treatment of opioid dependence and chronic pain in adult patients, including those requiring opioid substitution therapy and individuals with severe, refractory pain where other treatments are insufficient.

GNH USA supplies Lefisyo as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide. The company adheres to EU GMP standards and provides full regulatory documentation, ensuring reliable sourcing for health‑care providers across multiple continents.

Levomethadone Hydrochloride is used in opioid dependence management and chronic pain control.

Opioid dependence: reduces withdrawal symptoms, cravings, and stabilizes opioid tolerance during maintenance therapy. Chronic pain: provides long‑acting analgesia for severe pain conditions unresponsive to non‑opioid agents. Opioid substitution therapy: facilitates safe transition from heroin or other opioids to a regulated medication under medical supervision. Post‑operative pain: offers effective analgesia for patients after major surgery. Cancer pain: can be used as part of multimodal pain management in advanced malignancy.

Levomethadone Hydrochloride may cause a range of adverse reactions, varying from mild to severe.

Common Side Effects: - Nausea - Constipation - Dizziness - Drowsiness - Sweating

Serious or Rare Side Effects: - Respiratory depression - QT interval prolongation - Severe hypotension - Dependence or addiction potential

When prescribing Lefisyo, clinicians should consider several safety measures.

Assess patient history: evaluate prior opioid use and tolerance. Monitor respiratory function: watch for depression especially during initiation. Avoid concurrent CNS depressants: limit use with benzodiazepines or alcohol. Adjust dose in renal/hepatic impairment: consider reduced dosing. Educate patient on signs of overdose: instruct to seek immediate help if breathing slows. Store at ambient temperature below 25°C: keep in original container, protect from moisture and light.

Levomethadone Hydrochloride can interact with other medicines, requiring careful management.

Major Interactions (Avoid): - Concomitant use with other full opioid agonists: risk of additive respiratory depression. - Benzodiazepines or barbiturates: increased CNS depression. - Monoamine oxidase inhibitors (MAOIs): potential for severe hypotension.

Moderate Interactions (Monitor Closely): - CYP3A4 inhibitors (e.g., ketoconazole): may increase levomethadone levels. - CYP3A4 inducers (e.g., rifampin): may reduce efficacy. - Serotonergic agents: risk of serotonin syndrome.
