Indications and Uses of Piracetam
Piracetam is indicated for various cognitive and neurological conditions, with applications supported by clinical research and off-label use:
Cortical Myoclonus: Treats progressive myoclonus epilepsy, reducing seizure frequency and severity, approved in Europe, per neurology guidelines.
Cognitive Impairment: Improves memory and cognition in elderly patients with dementia or mild cognitive impairment, supported by geriatric studies.
Post-Stroke Recovery: Enhances recovery of cognitive and motor functions post-stroke, used off-label to improve rehabilitation outcomes, with evidence from stroke research.
Dyslexia: Manages reading and learning difficulties in children with dyslexia, used off-label to enhance cognitive processing, supported by pediatric studies.
Alzheimer’s Disease: Investigated off-label to slow cognitive decline in early Alzheimer’s, improving daily functioning, with data from neurodegenerative disease trials.
Traumatic Brain Injury (TBI): Employed off-label to support cognitive recovery after TBI, reducing long-term deficits, noted in trauma neurology research.
Vertigo and Balance Disorders: Treats vertigo associated with vestibular disorders, used off-label to stabilize balance, with otolaryngology evidence.
Sickle Cell Disease: Explored off-label to reduce vaso-occlusive crises and improve cerebral blood flow in sickle cell patients, supported by hematology studies.
Parkinson’s Disease: Investigated off-label as an adjunct to levodopa, enhancing motor and cognitive symptoms, with emerging data from movement disorder research.
Attention Deficit Hyperactivity Disorder (ADHD): Used off-label in children with ADHD to improve focus and attention, though evidence is limited, requiring pediatric oversight.
Dosage of Piracetam
Dosage for Adults
Cortical Myoclonus: 7.2 g/day in 2–3 divided doses, titrated up to 24 g/day based on response, taken with food.
Cognitive Impairment or Post-Stroke Recovery: 1.2–4.8 g/day in 2–3 divided doses, adjusted for efficacy, typically with meals.
Vertigo: 2.4–4.8 g/day in divided doses, maintained for 1–3 months.
Dosage for Children

Myoclonus (6+ years): 50 mg/kg/day, increased to 100–300 mg/kg/day based on response, with monitoring.
Dosage for Pregnant Women
Pregnancy Category C: Limited data; avoid unless benefits outweigh risks. Consult an obstetrician, with fetal monitoring if used.
Dosage Adjustments
Renal Impairment: Reduce dose based on creatinine clearance (e.g., CrCl 20–40 mL/min: 2/3 normal dose; CrCl <20 mL/min: 1/3 normal dose).
Hepatic Impairment: No adjustment needed; monitor in severe cases.
Elderly: Start with 1.2 g/day; increase gradually to 4.8 g/day if tolerated.
Concomitant Medications: Adjust if combined with CNS depressants or stimulants, monitoring for interactions.
Additional Considerations
- Take this active ingredient with food or water to reduce gastrointestinal irritation.
- Use a syringe for accurate dosing of oral solution in children.
How to Use Piracetam
Administration:
Swallow tablets whole or use oral solution with a meal or snack; IV use requires healthcare supervision.
Administer in divided doses to maintain steady levels, using a calibrated syringe for liquid forms.
Timing: Use 2–3 times daily, preferably with meals, maintaining consistency.
Monitoring: Watch for headache, nervousness, or signs of gastrointestinal upset (e.g., nausea).
Additional Tips:
- Store at 15–30°C (59–86°F), protecting from moisture and heat.

Contraindications for Piracetam
Hypersensitivity: Patients with a known allergy to Piracetam or racetams.
Severe Renal Impairment: Contraindicated if CrCl <20 mL/min due to accumulation risk.
Hemorrhagic Stroke: Avoid due to potential bleeding risk.
Pregnancy (unless critical): Contraindicated unless life-saving.

These effects may subside with dose optimization.
Serious Side Effects
Seek immediate medical attention for:
- Neurological: Seizures, agitation, or hallucinations.
