What Is Naltrexone?
Naltrexone HCl is a prescription medicine used to treat both alcohol use disorder and opioid use disorder. It is not a cure for addiction but a tool to help reduce cravings and support a person’s recovery journey.
Drug Overview and Approval
Naltrexone is a pure opioid antagonist. This means it works by blocking the euphoric and sedative effects of opioids such as heroin, morphine, and codeine. For alcohol dependence, it helps reduce the rewarding feelings associated with drinking. It is a key component of a comprehensive substance use disorder treatment program.
Medical Indications
This medication is indicated for:
- The treatment of alcohol use disorder (AUD) to reduce cravings and the risk of relapse.
- The prevention of relapse to opioid use, after a person has completed opioid detoxification. It is important to be free of opioids for at least 7-10 days before starting naltrexone to avoid withdrawal symptoms.
How Naltrexone Works and Benefits
Naltrexone provides a unique mechanism to support recovery by altering the body’s response to alcohol and opioids.
Mechanism of Action
Naltrexone works by binding to and blocking opioid receptors in the brain. This action prevents the “high” or feelings of euphoria that people feel when they consume opioids or alcohol. By blocking these effects, it helps to extinguish the learned behavior of using these substances for pleasure, thereby reducing cravings.
Relapse Prevention Benefits
When used as part of a complete treatment plan that includes counseling and therapy, naltrexone has been shown in clinical studies to significantly help patients maintain abstinence. It empowers individuals by reducing the urge to use, making it easier to focus on recovery and build coping skills for long-term success.
Dosage & Administration
Following the prescribed dosage and administration instructions from your healthcare provider is crucial for the medication to work effectively.
Dosage Forms and Strength
Naltrexone hydrochloride is available as 50 mg oral tablets. The typical starting dose for both AUD and OUD is 50 mg taken once per day.
How to Take Naltrexone
The tablet can be taken with or without food. If it causes stomach upset, taking it with a meal or a glass of water or milk may help. It is important to take the medication at the same time each day to maintain consistent levels in your system.
Missed Dose and Refill Information
If you miss a dose of Naltrexone, take it as soon as you remember. However, if it is almost time for your next dose, skip the missed one. Do not take two doses at once. You can get your naltrexone refill online by getting in touch with your doctor for a prescription renewal.
Side Effects, Warnings and Precautions
Before taking naltrexone, discuss your full medical history with your provider.
Common Side Effects
Some common naltrexone side effects may include:
- Nausea, vomiting, or stomach pain
- Headache
- Dizziness or fatigue
- Anxiety or nervousness
- Sleep problems
Serious Warnings
Do not take naltrexone if you are currently physically dependent on opioids, as it can cause sudden and severe withdrawal symptoms. It is also contraindicated in patients with acute hepatitis or liver failure. Your doctor will perform tests to check your liver function before and during treatment.
Drug Interactions
Avoid all opioid-containing medications (including certain cough and cold remedies and anti-diarrhea products) and illicit opioids while taking naltrexone. Using opioids in large amounts to overcome the blocking effect of naltrexone can lead to serious injury, coma, or death.
