Yes, you can take Keppra before a colonoscopy
You should continue taking Keppra (levetiracetam) on your regular schedule before your colonoscopy, including on the day of the procedure. The FDA label for Keppra does not list any contraindications or precautions related to colonoscopy or bowel preparation 1. There is no evidence that levetiracetam interferes with bowel preparation quality or increases procedural risks.
Key Points for Safe Administration
Timing with clear liquids: Keppra can be taken with clear liquids up to 2 hours before your procedure, which aligns with current anesthesia fasting guidelines 2, 3, 2, 3. The 2023 American Society of Anesthesiologists guidelines permit clear liquid intake until 2 hours before sedation without affecting aspiration risk 3.
Take with water during bowel prep: You can swallow your Keppra tablets with water during your bowel preparation period. The medication should be taken at your usual scheduled times—typically twice daily 1. Do not skip doses, as stopping antiepileptic medications suddenly can trigger seizures, including status epilepticus 1.
Practical Considerations
Absorption is not affected: Research demonstrates that levetiracetam maintains comparable bioavailability throughout the entire gastrointestinal tract, including the proximal small bowel, distal small bowel, and ascending colon 4. This means bowel preparation will not significantly impair drug absorption.
No drug interactions with sedation: Levetiracetam has minimal drug-drug interactions and does not interact with the benzodiazepines (midazolam) or opioids (fentanyl, meperidine) commonly used for colonoscopy sedation 5, 6. The medication's favorable side effect profile makes it safe to continue during procedures 1.
Important Caveats
Inform your endoscopy team: Tell your gastroenterologist and anesthesia provider that you take Keppra for seizure control. This is critical for your safety.
Swallow tablets whole: Take Keppra tablets intact with water—do not crush or chew them 1. If you cannot swallow tablets, discuss using the oral solution formulation with your physician beforehand.
Maintain seizure control: Missing even one dose increases your seizure risk. The consequences of breakthrough seizures (injury, aspiration, prolonged hospitalization) far outweigh any theoretical concerns about taking medication before colonoscopy.
The bottom line: Continue your Keppra as prescribed. Take it with small sips of water during your bowel preparation and up to 2 hours before your procedure time. Never discontinue antiepileptic medications without explicit physician guidance, as this creates serious safety risks 1.
