Keppra Patient Tips
Medically reviewed by C. Fookes, BPharm. Last updated on Dec 5, 2018.
How it works
- Keppra is a brand (trade) name for levetiracetam. Experts aren't sure exactly how levetiracetam works but suggest it dampens down excessive nerve firing and reduces seizure propagation, possibly through an impact on pathways involving calcium, glycine, and GABA.
- Keppra belongs to the class of medicines known as anticonvulsants (also called antiepileptics).
- Used in combination with other anticonvulsants for the treatment of partial onset seizures in adults and children over the age of one month, for generalized tonic-clonic seizures in adults and children over the age of six, and for the treatment of myoclonic seizures in adults and adolescents over the age of 12.
- Does not require monitoring of blood concentrations.
- Available as oral tablets, extended-release tablets (Keppra-XR) and as an oral solution.
- Usually taken once or twice daily.
- Keppra is available as a generic under the name levetiracetam.
If you are between the ages of 18 and 60, take no other medication or have no other medical conditions, side effects you are more likely to experience include:
- Drowsiness which may affect your ability to drive or operate machinery. Avoid alcohol.
- Aggression, nasal congestion, headache, decreased appetite, infection, dizziness, pain, sore throat, depression, nervousness, and fatigue are reasonably common side effects. Hematologic abnormalities, co-ordination difficulties and serious dermatological reactions (for example, Stevens-Johnson syndrome [SJS] and toxic epidermal necrolysis [TEN]) have also been reported.
- Young children are more likely than adults to experience behavioral abnormalities (eg, overactivity or agitation) or psychotic symptoms as well as other side effects such as a decreased appetite, increased blood pressure, or nasal congestion while taking Keppra.
- As with other antiepileptics, Keppra may increase the risk of suicidal thoughts or behavior. Monitor for worsening depression or mood changes. Keppra may also cause behavioral problems such as aggression, anxiety, irritability, and nervousness; advise people taking Keppra to monitor their mood.
- The dosage of Keppra needs reducing in people with kidney disease.
- May not be suitable for some people including those with kidney disease, with a history of mental health problems, who are pregnant or breastfeeding.
- May interact with some medications, such as propoxyphene, buprenorphine, and sedating antihistamines; however, generally, less likely to interact with other medications than some other anticonvulsants.
- In children aged 1 month to 4 years, Keppra has been associated with an increase in blood pressure.
- Alcohol may worsen the side effects of Keppra such as drowsiness and dizziness.
- Withdrawal of Keppra may cause an increase in seizure frequency. Keppra should be tapered off slowly on discontinuation.
Notes: In general, seniors or children, people with certain medical conditions (such as liver or kidney problems, heart disease, diabetes, seizures) or people who take other medications are more at risk of developing a wider range of side effects.

- Keppra may be given with or without food.
- Take exactly as directed. Do not increase or decrease the dosage without your doctor's advice.
- If you are giving Keppra solution to a child or taking it yourself, use the dosing syringe provided or use a properly calibrated liquid measure (these can be bought from a drug-store). Do not use a kitchen teaspoon.
- Extended-release tablets should be swallowed whole. Do not crush, chew or break.
- When it comes time to discontinue Keppra, your doctor will advise you on a slowly tapering dosing schedule. Do not just stop it suddenly unless your doctor has advised you that a rapid withdrawal is justified.
- Talk to your doctor if you feel like your mood has changed for the worse or you have any thoughts about suicide or self-harm. Keppra may also cause aggression, anxiety, depression, and irritability.
- Keppra may cause drowsiness or coordination difficulties and affect your ability to drive or operate machinery. Avoid alcohol.
- Talk to your doctor immediately if you develop a rash or any other worrying side effects while taking Keppra.
Response and Effectiveness
- Keppra is rapidly and almost completely absorbed after oral administration. It reduces seizure frequency by about half in 20 to 40% of people who take it.
- Keppra tablets and oral solution are absorbed to the same extent.
