Keppra, also known as levetiracetam, is an antiepileptic drug used to treat seizures in adults and children. It works by reducing abnormal electrical activity in the brain that causes seizures. While Keppra can be an effective treatment for seizures, it may cause side effects and withdrawal symptoms when discontinued. In this response, we will delve into the medication, its mechanism of action, side effects, and withdrawal symptoms in detail.
Keppra is believed to work by binding to a specific protein in the brain called synaptic vesicle protein 2A (SV2A), which is involved in the release of neurotransmitters. By binding to SV2A, Keppra reduces the release of neurotransmitters, such as glutamate, which can cause seizures.
Keppra does not appear to affect other neurotransmitter systems, such as gamma-aminobutyric acid (GABA) or serotonin, which are targeted by other antiepileptic drugs. This selective mechanism of action is thought to contribute to Keppra’s relatively low incidence of side effects compared to other antiepileptic drugs.
How to take Keppra
The appropriate dosage of Keppra depends on several factors, including the patient’s age, weight, health status, and the type of seizures being treated.
The starting dose of Keppra for adults is usually 1000 mg/day, divided into two doses of 500 mg each. The dose can be increased gradually by 1000 mg/day every two weeks, up to a maximum dose of 3000 mg/day. For children, the starting dose is based on their weight, typically 20 mg/kg/day divided into two doses, up to a maximum dose of 60 mg/kg/day.
The dose of Keppra may need to be adjusted for patients with impaired kidney function, as the medication is eliminated from the body primarily through the kidneys. In patients with moderate to severe kidney impairment, the starting dose should be reduced by 50% and the dose should be increased more slowly. Patients with end-stage renal disease may need a further reduction in dose.
In elderly patients, the starting dose of Keppra should be reduced to avoid adverse effects. Patients with liver disease should also receive a lower starting dose and the dose should be increased more slowly.
It’s important to follow a doctor’s instructions for taking Keppra and not to change the dose or stop taking the medication without medical supervision. Abruptly stopping Keppra can cause seizures or other serious complications, so it’s crucial to follow a doctor’s instructions for tapering off the medication if necessary.
Withdrawal Symptoms
When a person stops taking Keppra, they may experience withdrawal symptoms. These symptoms can occur even with a gradual reduction in dose and can be severe in some cases. The most common withdrawal symptoms reported with Keppra include:
• Seizures
• Mood changes, such as anxiety, irritability, and depression
• Insomnia or changes in sleep patterns
• Headaches
• Nausea or vomiting
• Dizziness or lightheadedness
• Flu-like symptoms such as fever, body aches, and chills
It’s important to note that sudden discontinuation of Keppra can cause seizures and other serious complications, so it’s crucial to follow a doctor’s instructions for tapering off the medication. In some cases, the doctor may recommend switching to another medication before discontinuing Keppra altogether.
Keppra Withdrawal Timeline
The withdrawal timeline from Keppra, a medication used to treat seizures, can vary depending on the individual and the dosage they were taking. Generally speaking, it may take several weeks to gradually reduce the dosage to avoid withdrawal symptoms. Some people may experience withdrawal symptoms even with a gradual reduction in dose.
The first step in the Keppra withdrawal process is to consult with a doctor. The doctor will assess the patient’s current condition and determine an appropriate tapering schedule. This schedule may involve gradually reducing the dose of Keppra over several weeks or months, depending on the patient’s individual needs.
During the tapering process, the patient may experience some withdrawal symptoms. Common withdrawal symptoms from Keppra include seizures, mood changes (such as anxiety, irritability, and depression), insomnia or changes in sleep patterns, headaches, nausea or vomiting, dizziness or lightheadedness, and flu-like symptoms such as fever, body aches, and chills.
It’s important to note that sudden discontinuation of Keppra can cause seizures and other serious complications, so it’s crucial to follow a doctor’s instructions for tapering off the medication. In some cases, the doctor may recommend switching to another medication before discontinuing Keppra altogether.
The duration of the Keppra withdrawal timeline depends on several factors, including the patient’s age, health status, dosage of medication, and how long they have been taking the medication. Some patients may experience withdrawal symptoms for several weeks or even months after discontinuing the medication.
It’s important to stay in close contact with a doctor throughout the withdrawal process. The doctor may need to adjust the tapering schedule or recommend additional treatments to manage withdrawal symptoms. In some cases, the doctor may recommend a gradual reintroduction of Keppra to help ease withdrawal symptoms.
In conclusion, the Keppra withdrawal timeline can vary depending on the individual and the dosage they were taking. It’s crucial to follow a doctor’s instructions for tapering off the medication to avoid the risk of seizures or other withdrawal symptoms. If you’re experiencing withdrawal symptoms or have concerns about discontinuing Keppra, speak with your doctor.
Keppra Side effects

• Suicidal thoughts or behaviors
• Allergic reactions, such as rash or swelling
• Blood disorders, such as low white blood cell count
• Liver problems, such as hepatitis or jaundice
