Common use
Naltrexone is an opioid antagonist used to support recovery from alcohol and opioid dependence. It is FDA-approved to help reduce the urge and craving for substances, and it blocks the euphoric and sedative effects of opioids.
Naltrexone is a valuable component in recovery treatment and is especially effective when used in combination with behavioral therapy or counseling. It is important to note that naltrexone is not a cure but can significantly improve recovery outcomes for people diagnosed with alcohol use disorder or opioid dependence.
This medication is also used as part of a long-term plan for sobriety, under the supervision of a licensed healthcare provider. Patients should engage in a structured recovery program and remain in close contact with their care team.
Many individuals who are prescribed naltrexone receive additional support through educational resources and professional counseling to enhance their chances of maintaining abstinence. If you're looking to buy naltrexone, ensure it is done through a verified and legal source with a proper prescription.
Dosage and direction
Take naltrexone exactly as prescribed by your doctor or addiction specialist. For treatment of opioid dependence, the standard oral dosage is 50 mg once daily. In cases of alcohol dependence, the dose naltrexone remains similar but may be modified depending on response and tolerance.
Before initiating treatment, a complete detoxification from opioids is required. Patients must be opioid-free for at least 7 to 10 days to avoid precipitated withdrawal - a serious complication that may occur if opioids are still present in the body.
Tablets are to be taken with water and may be consumed with or without food. Consistency in taking the medication daily is crucial for effectiveness. Always follow the treatment guidelines provided by your healthcare provider.
Do not consume alcohol or use any opioid-based substances while on this medication, as it may reduce the drug's effectiveness or cause adverse effects.
Precautions
Before using naltrexone, inform your doctor of the following:
- Liver conditions or hepatitis
- Renal (kidney) impairment
- Mental health history, including depression or suicidal ideation
- Any bleeding disorder or abnormal bruising
Patients with liver problems should undergo regular liver function tests. While taking naltrexone, avoid activities such as driving or operating machinery if you experience fatigue, dizziness, or drowsiness.
Close monitoring by a medical care provider ensures that any side effects or complications are addressed early and effectively.
Contraindications
Do not begin treatment with naltrexone if you:
- Are currently using opioids or undergoing opioid withdrawal
- Have severe liver failure or acute hepatitis
- Have known allergies to naltrexone or any of its inactive ingredients
Pregnant or breastfeeding individuals should consult their doctor before starting therapy. The decision to use this medication during pregnancy must weigh potential benefits against risks.
All medical conditions should be discussed thoroughly with your provider to ensure this treatment is safe for you.
Possible side effects
Most patients tolerate naltrexone well. However, some side effects may occur:
- Nausea or gastrointestinal discomfort
- Headache
- Fatigue, drowsiness, or dizziness
- Insomnia or restlessness
Less common but serious reactions include:
- Signs of liver damage, such as yellowing of the skin or eyes
- Serious mood changes, depression, or suicidal thoughts
- Pain or swelling at the injection site (if using the injectable form)
Seek medical advice if you notice unusual physical or emotional changes while taking naltrexone.
Drug interactions
Inform your doctor if you are taking:
- Opioid-containing painkillers (e.g., morphine, fentanyl)
- Cough or cold remedies with codeine
- Anti-diarrheal medications like loperamide
Taking opioids with naltrexone may not only render the opioid ineffective but could also lead to overdose if high doses are consumed to overcome the blockade. Always carry a medical alert card or wear a bracelet stating that you are taking naltrexone.
Missed dose
If a dose is missed, take it as soon as possible. If it is near the time of your next dose, skip the missed one and resume your regular schedule. Never double the dose to compensate for the one you missed.
Overdose
Although overdosing on naltrexone is uncommon, it can still cause significant issues such as nausea, vomiting, or potential liver damage. If you suspect an overdose, seek medical attention immediately. Symptoms may vary depending on the amount taken and other underlying health conditions.
Storage
Store naltrexone at controlled room temperature (68°F to 77°F or 20°C to 25°C). Avoid exposure to excessive heat or moisture. Do not store in the bathroom, and keep the medication tightly sealed. Ensure it is out of the reach of children and pets. If ordering online, confirm that shipping conditions follow proper storage protocols to maintain product integrity.
