Side effects
Dizziness, drowsiness, headache, nausea, nervousness, lightheadedness, restlessness, blurred vision, tiredness, and trouble sleeping may occur.
Rarely, patients taking buspirone Hcl may develop movement disorders such as shakiness (tremors), muscle stiffness, mask-like facial expression, jerky walking movements, or a condition known as tardive dyskinesia. In some cases, these conditions may be permanent. Tell your doctor right away if you develop any unusual/uncontrolled movements (especially of the face, mouth, tongue, arms, or legs).
