Levetiracetam

Levetiracetam 500 mg Tablets

Levetiracetam, a new-generation antiepileptic drug (AED), is used to control and prevent seizures of various types in both adults and children. It works via a unique mechanism, binding to the SV2A protein in the brain, helping regulate abnormal electrical activity that triggers seizures.

Indications

Partial-Onset Seizures: Used as monotherapy or adjunct therapy for focal seizures.

Myoclonic Seizures: Effective in controlling myoclonic jerks, especially in juvenile myoclonic epilepsy.

Tonic-Clonic Seizures: Provides control in generalized (grand mal) seizures.

Maintenance Therapy: Requires daily continuous use to maintain a seizure-free state.

How to Use

Regular Dosing: Take doses 12 hours apart daily to maintain stable blood levels.

With or Without Food: Can be taken with or without meals, though taking with food may reduce stomach upset.

Administration: Swallow the tablet whole with water—do not crush or chew.

Do Not Stop Suddenly: Abrupt discontinuation may lead to rebound seizures with increased severity.

An Essential Safety Alert

Mental Health Monitoring: Some patients may experience mood changes, irritability, or suicidal thoughts. Report any unusual symptoms immediately.

Kidney Function: Since the drug is renally excreted, dose adjustment may be required in kidney impairment.

Alcohol Avoidance: Alcohol may increase drowsiness and the risk of seizures.

Caution with Activities: May cause dizziness or sleepiness, especially initially—avoid driving or operating machinery until effects are known.

Common Side Effects

Most side effects are mild and improve as the body adjusts:

• Sleepiness or fatigue
• Dizziness
• Headache
• Nasal congestion
• Irritability or mood changes
