Up to 10 percent of people who take naltrexone have nausea. If you get any of these side effects, tell your doctor. He or she may change your treatment or suggest ways you can deal with the side effect. You and your doctor have to decide this. Most people take the medicine for 12 weeks or more.
Naltrexone only has to be taken once a day.
Be sure to take naltrexone just the way your doctor tells you to. Don't take extra pills, don't skip pills and don't stop taking pills until you talk to your doctor.
