Why do I need this medicine?

Naltrexone is used as a supportive therapy in maintaining abstinence from alcohol.

This medicine may also be used to help overcome the addiction of those who are dependent on certain medicines such as opioids.

This medicine is meant to be taken as part of a management plan that should include patient education and counselling.

How do I take this medicine?

Take Naltrexone exactly as directed by your doctor or according to the instructions on the label. Do not take more or less than instructed by your doctor.

You may take this medicine with or without food. Try to take it at the same time each day.

It is important that you stop taking any opioid medicine for at least 7-10 days before starting on Naltrexone therapy. This medicine may cause withdrawal symptoms if you still have any trace of opioids in your body. Your doctor may perform tests to ensure opioid levels remain undetectable before you start with the treatment.

What should I do if I have forgotten to take this medicine?

Take the missed dose as soon as you remember. If it is almost time for your next dose, skip the missed dose and return to your normal dosing schedule.
