Remeron is an antidepressant medication. It is used to treat major depressive disorder (MDD).
Remeron can increase the risk of suicidal thoughts and behavior in children, adolescents, and young adults. Your doctor will monitor you closely for clinical worsening, suicidality, or unusual behavior after you start taking Remeron or a new dose. Tell your doctor immediately if you experience anxiety, hostility, sleeplessness, restlessness, impulsive or dangerous behavior, or thoughts about suicide or dying; or if you have new symptoms or seem to be feeling worse.
You can experience manic episodes while you are taking Remeron. Tell your doctor if you experience greatly increased energy, severe trouble sleeping, racing thoughts, reckless behavior, unusually grand ideas, excessive happiness or irritability, or talking more or faster than usual.
Remeron can lower your white blood cells called neutrophils (type of blood cells that fight infections). Tell your doctor if you develop fever, chills, sore throat, mouth or nose sores, or other “flu-like” symptoms.
Remeron can cause serotonin syndrome (a potentially life-threatening drug reaction that causes the body to have too much serotonin, a chemical produced by the nerve cells) or neuroleptic malignant syndrome (a brain disorder) when you take it alone or in combination with other medicines. You can experience agitation, hallucinations, coma or other mental status changes; coordination problems or muscle twitching (overactive reflexes); racing heartbeat, high or low blood pressure; sweating or fever; nausea, vomiting, or diarrhea; or muscle rigidity. Tell your doctor right away if you experience any of these signs or symptoms.
Remeron can cause seizures or changes in your appetite or weight. Your doctor will monitor you for these effects during treatment. Also, Remeron can decrease your blood sodium levels, especially if you are elderly. Tell your doctor if you have a headache, weakness, feeling unsteady, confusion, problems concentrating or thinking, or memory problems while you are taking Remeron.
Remeron can cause severe allergic reactions or severe skin reactions. Stop taking this medication and tell your doctor immediately if you develop a rash, trouble breathing, or swelling of your face, tongue, eyes, or mouth.
Do not stop taking Remeron without first talking to your doctor. Stopping Remeron suddenly can cause serious symptoms, including dizziness, abnormal dreams, agitation, anxiety, fatigue, confusion, headache, shaking, tingling sensation, nausea, vomiting, or sweating.
