  • What is Remeron?

    Remeron is used to treat a certain type of depression called major depressive disorder.

  • What is the most important information I should know about Remeron?

    Antidepressant medicines, including Remeron, may increase suicidal thoughts or actions in some children, teenagers, and young adults when the medicine is first started. Depression and other serious mental illnesses are the most important causes of suicidal thoughts and actions. People with bipolar disorder or who have a family history of this condition (also called manic-depressive illness) are at a greater risk. Contact your doctor immediately if you experience any changes, especially sudden ones, in mood, behavior, thoughts, or feelings. Signs to watch for include new or worsening depression, new or worsening anxiety, agitation, insomnia, hostility, panic attacks, restlessness, extreme hyperactivity, and suicidal thinking or behavior. This is very important when an antidepressant medicine is first started or when the dose is changed.

    Never combine Remeron with any drug classified as an MAOI, a class of drugs used to treat depression, psychiatric or emotional disorders, or Parkinson's disease. Remeron and MAOIs should not be taken together or within 14 days of each other. Combining these drugs with Remeron can cause serious and even fatal reactions such as high body temperature, muscle rigidity, twitching, and agitation, leading to delirium and coma.

    If you develop signs and symptoms of fever, sore throat, fever, inflammation of your mouth, or other signs of infection, contact your doctor immediately as this may be a sign of a serious side effect of Remeron.

    Remeron may cause a severe, possibly life-threatening condition called serotonin syndrome (a potentially life-threatening drug reaction that causes the body to have too much serotonin, a chemical produced by the nerve cells). Contact your doctor immediately if you experience any of the following symptoms: agitation, hallucinations, fast heartbeat, changes in blood pressure, increased body temperature, lack of coordination, or overactive reflexes.

    While you may feel better with Remeron therapy in 1 to 4 weeks, you should continue therapy as directed. Do not stop taking Remeron without first talking with your doctor as this can cause serious side effects.

    This drug may impair the mental and/or physical abilities required for performing potentially hazardous tasks such as driving or operating machinery. These effects may become worse if you combine Remeron with alcohol or certain medicines.
