Important Safety Information

  • Pregnancy: Do not take BELVIQ if you are pregnant or planning to become pregnant. BELVIQ may harm your unborn baby, as weight loss offers no potential benefit to a pregnant woman.
  • Serotonin Syndrome or Neuroleptic Malignant Syndrome (NMS)-like reactions: Before using BELVIQ, tell your doctor about all the medicines you take, especially medicines that treat depression, migraines, mental problems, or the common cold. These medicines may cause serious or life-threatening side effects if taken with BELVIQ. Call your doctor right away if you experience agitation, hallucinations, confusion, or other changes in mental status; coordination problems; uncontrolled muscle spasms; muscle twitching; restlessness; racing or fast heartbeat; high or low blood pressure; sweating; fever; nausea; vomiting; diarrhea; or stiff muscles.
  • Valvular heart disease: Some people taking medicines like BELVIQ have had heart valve problems. Call your doctor right away if you experience trouble breathing; swelling of the arms, legs, ankles, or feet; dizziness, fatigue, or weakness that will not go away; or fast or irregular heartbeat. Before taking BELVIQ, tell your doctor if you have or have had heart problems.
  • Changes in attention or memory: BELVIQ may slow your thinking. You should not drive a car or operate heavy equipment until you know how BELVIQ affects you.
  • Mental problems: Taking too much BELVIQ may cause hallucinations, a feeling of being high or in a very good mood, or feelings of standing outside your body.
  • Depression or thoughts of suicide: Call your doctor right away if you notice any mental changes, especially sudden changes in your mood, behaviors, thoughts, or feelings, or if you have depression or thoughts of suicide.
  • Low blood sugar: Weight loss can cause low blood sugar in people taking medicines for type 2 diabetes, such as insulin or sulfonylureas. Blood sugar levels should be checked before and while taking BELVIQ. Changes to diabetes medication may be needed if low blood sugar develops.
  • Painful erections: If you have an erection lasting more than 4 hours while on BELVIQ, stop taking BELVIQ and call your doctor or go to the nearest emergency room right away.
