Levetiracetam, commonly known by its brand name Keppra, is an anti-epileptic drug (AED) prescribed to manage seizures in individuals with epilepsy. Available in various dosages, including 250mg and 500mg tablets, Keppra plays a significant role in controlling seizures and improving the quality of life for those affected by this neurological condition. This comprehensive guide delves into the key aspects of Keppra 500mg and 250mg, including its uses, dosage, side effects, precautions, and frequently asked questions. Understanding this medication is crucial for patients and caregivers to ensure its safe and effective use. Please note: This information is for educational purposes only and does not constitute medical advice. Always consult your doctor before ordering Keppra or taking any medication.
Understanding Keppra's Mechanism of Action:
Keppra works differently than many other AEDs. Its exact mechanism isn't fully understood, but it's believed to modulate the release of neurotransmitters, impacting neuronal excitability and thus reducing the occurrence of seizures. It doesn't target specific ion channels like some other anti-seizure medications, offering a unique approach to seizure control.
Therapeutic Uses of Keppra 500mg and 250mg:
Keppra is primarily prescribed for the following conditions:
- Epilepsy: Both as monotherapy (single medication) and adjunctive therapy (used in conjunction with other AEDs) for partial-onset seizures, myoclonic seizures, and tonic-clonic seizures in adults and children.
- Myoclonic Seizures: Keppra is particularly effective in managing myoclonic seizures, characterized by brief, involuntary muscle jerks.
- Lennox-Gastaut Syndrome: This severe form of epilepsy often responds favorably to Keppra, helping to reduce the frequency and severity of seizures.
Dosage and Administration:
The dosage of Keppra is individualized based on the patient's age, weight, condition, and response to treatment. Your doctor will determine the appropriate starting dose and adjust it as needed. Common dosages include:
- Initial Dose: Often starts at a lower dose and is gradually increased.
- Maintenance Dose: Can range from 1000mg to 3000mg daily, divided into two or three doses. The 250mg and 500mg tablets allow for flexible dosing adjustments.
It's crucial to follow the prescribed dosage and administration instructions precisely. Never adjust your dosage without consulting your physician. You can order Keppra or buy Keppra only through legitimate channels such as a pharmacy with a valid prescription.
Side Effects of Keppra:
Like most medications, Keppra can cause side effects, although not everyone experiences them. Common side effects include:
- Dizziness
- Drowsiness
- Fatigue
- Headache
- Nausea
- Weakness
- Somnolence
Less common but more serious side effects can include:
- Allergic reactions (rash, itching, swelling)
- Depression
- Suicidal thoughts

If you experience any concerning side effects, contact your doctor immediately.
Precautions and Interactions:
- Pregnancy and Breastfeeding: Consult your doctor regarding the risks and benefits of using Keppra during pregnancy or breastfeeding.
- Kidney Disease: Individuals with kidney problems may require dosage adjustments.
- Liver Disease: The medication may need to be administered cautiously in those with liver issues.
