From the Guidelines

Keppra (levetiracetam) is not specifically used to prevent strokes, and its use for this purpose is not supported by the available evidence. It is an anti-seizure medication primarily prescribed to treat epilepsy and prevent seizures. For stroke prevention, doctors typically recommend medications like aspirin, clopidogrel, warfarin, or direct oral anticoagulants depending on the stroke risk factors, as stated in the 2024 guideline for the primary prevention of stroke 1. These medications work by preventing blood clots that can cause strokes. Additionally, controlling high blood pressure with medications such as ACE inhibitors, ARBs, or calcium channel blockers is crucial for stroke prevention, as highlighted in the 2011 ASA/ACCF/AHA/AANN/AANS/ACR/ASNR/CNS/SAIP/SCAI/SIR/SNIS/SVM/SVS guideline on the management of patients with extracranial carotid and vertebral artery disease 1. Lifestyle modifications including regular exercise, a healthy diet low in sodium and saturated fats, smoking cessation, and limiting alcohol consumption are also important preventive measures.

Some key points to consider for stroke prevention include:

  • Managing hypertension through lifestyle modifications and medications, as recommended by the Seventh Report of the Joint National Committee for the Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC-7) 1
  • Using antiplatelet therapy, such as aspirin, for patients with antiphospholipid syndrome or systemic lupus erythematosus without a history of stroke or unprovoked venous thromboembolism, as stated in the 2024 guideline for the primary prevention of stroke 1
  • Controlling cholesterol levels through lifestyle modifications and medications, such as statins, as recommended by the 2011 ASA/ACCF/AHA/AANN/AANS/ACR/ASNR/CNS/SAIP/SCAI/SIR/SNIS/SVM/SVS guideline on the management of patients with extracranial carotid and vertebral artery disease 1
  • Managing diabetes through lifestyle modifications and medications, as highlighted in the 2011 ASA/ACCF/AHA/AANN/AANS/ACR/ASNR/CNS/SAIP/SCAI/SIR/SNIS/SVM/SVS guideline on the management of patients with extracranial carotid and vertebral artery disease 1

If you're concerned about stroke risk, you should consult with your healthcare provider who can assess your individual risk factors and recommend appropriate preventive strategies rather than using Keppra, which doesn't have a role in stroke prevention.

From the Research

Levetiracetam and Cerebral Vascular Accidents (Stroke)

  • There is no direct evidence to suggest that Levetiracetam (Keppra) prevents cerebral vascular accidents (stroke) 2, 3, 4.
  • However, Levetiracetam has been studied as a potential treatment for post-stroke seizures, which are a common complication of stroke 2, 5, 6.
  • Studies have shown that Levetiracetam can be effective in controlling seizures in patients with post-stroke epilepsy, particularly in the elderly population 5, 6.
  • The efficacy and safety of Levetiracetam in monotherapy for late post-stroke seizures in the elderly have been demonstrated in prospective studies 5, 6.
  • In these studies, a significant proportion of patients were seizure-free after treatment with Levetiracetam, and the drug was generally well-tolerated 5, 6.

Mechanism of Action and Pharmacokinetics

  • Levetiracetam has a unique mechanism of action, involving neuronal binding to synaptic vesicle protein 2A and inhibition of calcium release from intraneuronal stores 3, 4.
  • It also inhibits N-type calcium channels and opposes the activity of negative modulators of GABA- and glycin-gated currents 3, 4.
  • Levetiracetam has rapid and complete absorption, high oral bioavailability, and minimal metabolism, making it a convenient treatment option 3, 4.

Clinical Evidence

  • Clinical trials have established the efficacy of Levetiracetam in controlling seizures in patients with epilepsy, including those with partial-onset seizures and idiopathic generalized epilepsy 3, 4.
  • Levetiracetam has also been shown to improve health-related quality of life in patients with epilepsy 3, 4.
  • However, the evidence for Levetiracetam's ability to prevent cerebral vascular accidents (stroke) is limited, and further studies are needed to fully understand its potential benefits and risks in this context 2.
