Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

Tell your doctor immediately if any of these serious side effects occur: severe dizziness, fainting, fast/pounding/irregular heartbeat, mental/mood changes, fever, muscle stiffness/spasms/twitching, sweating, uncontrolled muscle movements (e.g., tongue and facial muscles), drooling, difficulty swallowing, seizures, frequent falls.
