Lyrica side effects

WARNING

Antiepileptic medications have been associated with increased risk of suicidal thinking and behavior. Anyone considering the use of antiepileptic drugs must balance this risk of suicide with the clinical need. Patients who are started on therapy should be closely observed for clinical worsening, suicidal thoughts, or unusual changes in behavior.

The most common side effects of Lyrica include:

  • dizziness
  • drowsiness
  • dry mouth (xerostomia)
  • edema (accumulation of fluid)
  • blurred vision
  • double vision (diplopia)
  • weight gain
  • fatigue (tiredness)
  • abnormal gait (ataxia)

  • myoclonus (sudden, involuntary jerking of a muscle or muscle groups)
  • heart failure
  • low blood pressure
  • vomiting
  • reduced blood platelet counts
  • increased blood creatinine kinase levels

Increased creatinine kinase can be a sign of muscle injury, and in clinical trials three patients experienced rhabdomyolysis (severe muscle injury). Therefore, patients should report unexplained muscle pain, tenderness, or weakness to their doctors, especially if associated with fever and malaise (reduced well-being). Lyrica has rarely been associated with angioedema (swelling of the face, tongue, lips, gums, throat, and larynx).
