Levetiracetam Hikma (Levetiracetam)

Levetiracetam is an antiepileptic medication used to control various seizure types.

• Partial‑onset seizures: Reduces frequency and severity of focal seizures.
• Generalized tonic‑clonic seizures: Controls convulsive episodes in generalized seizure disorders.
• Myoclonic seizures: Decreases sudden muscle jerks associated with myoclonic epilepsy.

• Levetiracetam binds selectively to the synaptic vesicle protein SV2A, a key regulator of neurotransmitter release. This interaction modulates synaptic transmission, decreasing the release of excitatory neurotransmitters and stabilizing neuronal firing. By reducing neuronal excitability, the drug helps prevent the initiation and spread of seizure activity across the central nervous system. The precise downstream effects are not fully understood, but SV2A binding is considered central to its anticonvulsant action.

Levetiracetam may be associated with a range of adverse reactions, varying in frequency and severity.

Common Side Effects

• Dizziness: sensation of light‑headedness or unsteadiness.
• Fatigue: generalized tiredness or lack of energy.
• Headache: mild to moderate cranial pain.
• Irritability: mood changes or increased agitation.

Serious or Rare Side Effects

• Severe allergic reaction: rash, swelling, or anaphylaxis.
• Mood or behavioral changes: depression, suicidal thoughts, or aggression.
• Hematologic abnormalities: low blood cell counts such as neutropenia.

When prescribing Levetiracetam, clinicians should consider several precautionary measures to ensure safe use.

• Renal function: Adjust dose in patients with impaired renal clearance.
• Pregnancy: Use only if potential benefit justifies potential risk, as safety data are limited.
• Psychiatric history: Monitor for new or worsening mood disorders.
• Concomitant CNS depressants: Observe for additive sedation or dizziness.
• Drug hypersensitivity: Discontinue if signs of severe allergic reaction appear.
• Store at ambient temperature: Keep in original container, protect from light and moisture, and store below 25 °C.

Levetiracetam can interact with other medicines, influencing its efficacy or safety.

Major Interactions (Avoid)

• Carbamazepine: May reduce levetiracetam plasma levels, decreasing effectiveness.
• Phenobarbital: Potential to lower levetiracetam concentrations.

Moderate Interactions (Monitor Closely)

• Valproic acid: May increase levetiracetam levels, requiring monitoring for toxicity.
• Alcohol: Combined use can enhance central nervous system depression.
• Other antiepileptics (e.g., phenytoin, lamotrigine): May require dose adjustments based on clinical response.
