  • Indigestion or stomach discomfort
• Neurological
  • Drowsiness or sedation
  • Restlessness (akathisia)

Restlessness (Akathisia)

Akathisia is a feeling of inner restlessness that can range from mild discomfort to overwhelming urge to move. It’s one of the more common neurological side effects of lurasidone.

Signs You Might Notice

• Inability to sit still (pacing, fidgeting)
• Anxiety or irritability coupled with an urge to move
• Restless leg sensations

Tips to Manage Restlessness

• Timing: Sometimes taking your dose earlier in the day helps.
• Movement Breaks: Short walks, gentle stretches or light exercise can ease discomfort.
• Relaxation Techniques: Deep breathing, guided imagery or meditation.
• Medication Adjustment: Your doctor may lower your dose or add a small dose of a beta-blocker or benzodiazepine for a short period.

Never adjust your dose without medical advice.

Food Rules: Taking Lurasidone with Food

Lurasidone absorption increases significantly when taken with food. To ensure you’re getting the right dose:

• Take lurasidone with at least 350 calories of food each time.
• A balanced snack (e.g., yogurt and fruit, a peanut butter sandwich, or a protein bar with juice) is fine.
• Avoid taking it on an empty stomach—this can reduce effectiveness and increase side effects.

Consistency matters. Pick meals or snacks you can have reliably at dosing times.

Monitoring While on Lurasidone

Regular check-ups help detect and manage side effects early:

• Baseline Assessments

  • Weight, BMI
  • Blood pressure and heart rate
  • Fasting blood glucose and lipid panel
  • Electrocardiogram (ECG) if you have cardiac risk factors

• Ongoing Monitoring

  • Weight and waist circumference every 3–6 months
  • Fasting glucose and lipids annually or as directed
  • Extrapyramidal symptoms (EPS) check at each visit
  • Mental health symptom review—are your moods and thoughts stable?

• Additional Tests

  • Prolactin levels if you develop hormonal symptoms (e.g., breast tenderness, menstrual changes)
  • Liver and kidney function tests in patients with known organ disease

Keeping a simple log of your weight, side effects, and food intake can be helpful for you and your doctor.

When to Seek Medical Help

Most side effects are mild, but some require prompt attention:

• Signs of severe restlessness or uncontrollable movements
• Chest pain, fainting, or irregular heartbeat
• Extreme drowsiness or confusion
• Signs of infection (fever, sore throat, rash)
• Unusual muscle stiffness combined with high fever and sweating (possible neuroleptic malignant syndrome)

If you experience any life-threatening or serious symptoms, call emergency services or go to the nearest emergency department.
