Levetiracetam Accord (Levetiracetam)

• Levetiracetam is an antiepileptic medication that modulates neuronal excitability to control seizure activity.
• Partial seizures: reduces frequency and severity of focal seizure episodes.
• Generalized seizures: helps achieve seizure freedom in tonic‑clonic and absence seizures.
• Epilepsy: provides adjunctive therapy for overall seizure control across diverse epilepsy syndromes.

• Levetiracetam binds to the synaptic vesicle protein SV2A, a key regulator of neurotransmitter release. This interaction modulates calcium‑dependent exocytosis, decreasing the release of excitatory neurotransmitters and stabilizing neuronal membranes. By reducing neuronal hyper‑excitability, the drug diminishes the propagation of epileptic discharges without directly affecting ion channels or G‑protein pathways.

Levetiracetam may cause a range of adverse reactions, varying from mild to serious.

Common Side Effects

• Dizziness: feeling of lightheadedness or unsteady balance.
• Fatigue: persistent tiredness or lack of energy.
• Headache: mild to moderate cranial pain.
• Nausea: upset stomach with possible vomiting.
• Irritability: mood changes or increased agitation.
• Somnolence: excessive sleepiness.

Serious or Rare Side Effects

• Severe allergic reaction: rash, swelling, or difficulty breathing.
• Mood or behavior changes: depression, suicidal thoughts, or aggression.
• Stevens‑Johnson syndrome: severe skin blistering.
• Hematologic abnormalities: low blood cell counts.
• Hepatic dysfunction: elevated liver enzymes.
• Acute psychosis: hallucinations or delusional thinking.

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

• Renal function: adjust dose in patients with impaired clearance.
• Psychiatric history: monitor for mood changes or suicidal ideation.
• Concomitant CNS depressants: use caution as sedation may increase.
• Pregnancy: evaluate risk‑benefit, as safety data are limited.
• Driving and machinery: advise patients to assess personal response before operating.
• Store at ambient temperature: keep tablets in original container, protect from moisture and light.

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

Major Interactions (Avoid)

• Carbamazepine: may reduce levetiracetam plasma levels.
• Phenobarbital: may decrease drug exposure.
• Enzyme‑inducing antiepileptics: can lower effectiveness.

Moderate Interactions (Monitor Closely)

• Sedatives or alcohol: may enhance CNS depression.
• Antidepressants (e.g., SSRIs): monitor for increased behavioral changes.
• Oral contraceptives: possible reduction in contraceptive efficacy.
• Antacids: may affect absorption if taken simultaneously.
