Understanding Vivitrol and Its Medical Uses

Vivitrol (naltrexone extended-release injectable suspension) is approved by the FDA for two indications: treatment of alcohol dependence in patients who are able to abstain from alcohol in an outpatient setting prior to initiation, and prevention of relapse to opioid dependence following opioid detoxification.

How Vivitrol Works

Vivitrol is an opioid antagonist that blocks opioid receptors, reducing the rewarding effects of alcohol and preventing opioids from producing their euphoric and other effects. As a monthly injectable, it offers sustained receptor blockade without requiring daily dosing.

Approved Patient Population

Vivitrol is intended for patients with alcohol dependence who can abstain from alcohol before starting treatment, or patients with opioid use disorder who have completed detoxification and are opioid-free.

Dosage and Administration

The recommended dose of Vivitrol is 380 mg administered as an intramuscular gluteal injection once every four weeks, alternating buttocks for each injection.

Warnings and Precautions for Vivitrol

Vivitrol does not carry a formal FDA boxed warning. However, patients and prescribers should be aware of the following important safety information.

Risk of Opioid Overdose

Patients who have been treated with Vivitrol have reduced tolerance to opioids. If a patient relapses and uses opioids after their tolerance has decreased, there is a risk of fatal overdose, including at doses previously tolerated.

Precipitated Opioid Withdrawal

Patients must be opioid-free for a minimum of 7 to 10 days before starting Vivitrol, as starting treatment too soon after opioid use can precipitate severe withdrawal symptoms.

Injection Site Reactions

Severe injection site reactions, in some cases requiring surgical intervention, have been reported. Injection sites should be monitored for signs of significant or worsening reactions.

Hepatotoxicity

Cases of hepatitis and liver dysfunction have been reported. Liver function should be monitored, particularly in patients with pre-existing liver conditions.

How to Access Vivitrol in India: A 6-Step Process

Step 1 – Search & request your medicine: The patient or treating doctor submits a request with basic details to initiate the access process.

Step 2 – Verification & eligibility review: The team verifies availability and reviews eligibility against regulatory and clinical requirements to ensure a compliant pathway.

Step 3 – Receive quote & delivery timeline: A transparent quotation is shared, covering medicine cost, logistics, and a clear delivery timeline.

Step 4 – Regulatory approval process: Assistance is provided to secure the approvals and documentation required for legal cross-border access.

Step 5 – Temperature-controlled import & handling: The medicine is sourced and transported under strict GDP-compliant conditions to maintain product integrity.

Step 6 – Secure delivery: The medicine is delivered to the patient or treating hospital, with updates provided at each stage.

Note: From request to delivery, every step is designed to ensure your treatment reaches you safely, compliantly, and without unnecessary delays.

Documentation and Availability of Vivitrol

Vivitrol is manufactured and marketed by Alkermes, Inc. It is sourced through authorized distribution channels for patients seeking named-patient import into India.

Required Documentation

Patients typically need a valid prescription from a treating addiction medicine specialist confirming diagnosis and, for opioid use disorder, confirmation of completed detoxification. NPP's regulatory team assists in preparing and verifying the documentation needed for a compliant import.

Availability

As an FDA-approved therapy for alcohol dependence and opioid relapse prevention, Vivitrol is sourced through authorized channels and imported under GDP-compliant, cold-chain logistics to preserve product quality throughout transit.

Sourcing and Delivery of Vivitrol

NPP sources Vivitrol directly from authorized pharmaceutical distributors to ensure product authenticity and full traceability. Every shipment is handled under Good Distribution Practice (GDP) conditions from origin to the patient's doorstep.

Cold Chain and Handling

Vivitrol should be stored refrigerated at 2°C to 8°C; it may be stored at temperatures not exceeding 25°C for no more than 7 days prior to administration, and must not be frozen. NPP maintains a continuous, monitored cold chain throughout transit.

Delivery Timelines

Once documentation and regulatory approvals are in place, delivery timelines are communicated transparently at the time of quotation, accounting for import clearance and last-mile cold-chain logistics to the patient's city.
