How Does Naltrexone Make You Feel?
Here are the Possible Side Effects


Nausea, headache, dizziness, anxiety, weariness, and difficulty sleeping are all possible side effects. Mild opiate withdrawal symptoms, such as stomach cramps, restlessness, bone/joint pain, muscular pains, and a runny nose, may occur in a limited percentage of persons. Inform your doctor or pharmacist right once if any of these side effects continue or worsen.

Remember that your doctor provided this medicine because he or she believes that the benefit to you outweighs the risk of adverse effects. Many people who use this drug do not have major adverse effects.

Within minutes of using naltrexone, opiate withdrawal symptoms might develop. If you have any of the following withdrawal symptoms, contact your doctor right away: stomach cramps, nausea/vomiting, diarrhea, joint/bone/muscle pains, mental/mood problems (such as anxiety, disorientation, severe tiredness, visual hallucinations), or a runny nose.

Side Effects That Don’t Require Immediate Attention

Some naltrexone adverse effects may occur, however they normally do not necessitate medical treatment. These adverse effects may subside as your body responds to the medication. In addition, your health care provider may be able to advise you on how to avoid or mitigate some of these adverse effects.

Precautions When Taking Naltrexone

Tell your doctor or pharmacist if you are allergic to naltrexone or if you have any other allergies before taking it. Inactive chemicals in this product may cause allergic reactions or other complications. For more information, consult your pharmacist.

Before taking this medicine, inform your doctor or pharmacist about your medical history, particularly of any recent or current use (within the previous 7 to 14 days) of any type of opioid substance (such as morphine, methadone, or buprenorphine), renal illness, or liver disease.

You should carry or wear medical identification that states that you are taking this medication so that proper treatment may be provided in the event of a medical emergency.

This medication may cause dizziness. You may become dizzy if you consume alcohol or marijuana (cannabis). Do not drive, operate equipment, or do anything else that requires attentiveness unless you are confident that you can do so safely. Consume no alcoholic beverages. If you use marijuana, see your doctor (cannabis).

After discontinuing naltrexone medication, you may become more sensitive to lower opioid dosages, raising your risk of potentially life-threatening opioid side effects (such as decreased breathing, loss of consciousness).

This medicine counteracts the effects of opiates (including heroin) and other related substances (opioids). Large doses of heroin or opioids, on the other hand, can bypass this restriction. Attempting to break through this barrier is extremely risky and can result in major damage, loss of consciousness, and death.

Drug Interactions

Drug interactions might alter the way your prescriptions operate or put you at risk for dangerous adverse effects. Maintain a list of all the items you use (including prescription and nonprescription medicines, as well as herbal supplements) and discuss it with your doctor and pharmacist. Do not start, stop, or modify the dosage of any medications without first consulting your doctor.
