Naltrexone HCL comes in two forms: tablets for oral administration and an extended-release injection. Always follow your doctor’s instructions precisely.
Oral Naltrexone HCL Tablets
Typical dosages range from 50mg to 100mg daily. Your doctor will determine the appropriate starting dose and any subsequent adjustments based on your individual needs and response to treatment. Take the tablets as directed, usually once daily with or without food.
Extended-Release Injectable Naltrexone
This formulation is administered by a healthcare professional. The typical dosage is a single injection of 380mg, repeated monthly. This provides a sustained release of naltrexone over a longer period. Schedule your injections carefully to maintain consistent levels of the medication in your system.
Important Guidelines
- Never abruptly stop taking naltrexone without consulting your doctor. Gradual tapering may be necessary to minimize potential withdrawal symptoms. Report any side effects to your doctor immediately. Common side effects include nausea, vomiting, headache, and fatigue. Some individuals may experience more serious side effects, requiring immediate medical attention. Avoid alcohol consumption while taking naltrexone. Combining alcohol with naltrexone can lead to adverse reactions. Inform your doctor about all other medications you are taking, including over-the-counter drugs and supplements. Some medications may interact with naltrexone. Follow the precise instructions provided by your doctor or pharmacist regarding dosage, timing, and administration method. Any deviation from the prescribed regimen should be discussed with your physician. Store naltrexone as directed on the label to maintain its efficacy and safety.
