Keppra is the brand name for levetiracetam, an antiseizure medicine used to help prevent seizures in people with epilepsy. It may be prescribed on its own or together with other seizure medicines. Keeping levetiracetam at a consistent level in the body is important for maintaining seizure control.
If you accidentally miss a dose of Keppra, you may not immediately feel different. However, the main concern is that missing a dose can reduce seizure protection and increase the chance of a breakthrough seizure. The risk varies from person to person and depends on factors such as the prescribed dose, seizure type, treatment schedule, and how many doses are missed.
A missed dose does not automatically mean that a seizure will happen. However, antiseizure medicines should generally be taken consistently because missing doses can make seizures more likely.
Key Takeaways
- Missing a dose of Keppra (levetiracetam) can reduce seizure protection and may increase the chance of a breakthrough seizure.
- Missing one dose does not mean a seizure will definitely occur, but the risk can vary depending on the individual and their treatment plan.
- If you remember a missed dose, follow the instructions for your specific Keppra formulation. Do not take two doses together unless your healthcare provider specifically tells you to.
- Missing multiple doses is more concerning and should be discussed with a doctor or pharmacist rather than corrected by taking extra medication.
- Taking Keppra at consistent times and using alarms, medication reminders, or a pill organizer can help prevent missed doses.
What Is Keppra?
Keppra is a brand name for levetiracetam. It is an antiseizure medicine prescribed to help control certain types of seizures.
Levetiracetam works by affecting signaling in the brain involved in seizure activity. It is available in several forms, including tablets, oral liquid, granules, and other formulations. Depending on the prescription, it may be taken once or twice a day.
The exact dose is different for each person. Doctors may also gradually increase or decrease the dose depending on seizure control and other factors.
Because epilepsy treatment depends on consistent medication use, it is important not to intentionally skip doses or stop Keppra without medical advice.
What Happens If You Miss a Dose of Keppra?
The most important possible consequence of missing Keppra is reduced seizure protection.
When you miss a scheduled dose, the amount of levetiracetam in your body can fall. Depending on the timing and your individual treatment plan, this may leave you less protected against seizures.
Some people may miss one dose and experience no noticeable symptoms. Others may experience a breakthrough seizure.
The NHS specifically advises people taking levetiracetam to take a missed dose when they remember unless it is nearly time for the next dose. If the next dose is due soon, the missed dose should be skipped. Two doses should not be taken together to make up for a missed dose.
Can Missing One Dose of Keppra Cause a Seizure?
Yes, it can.
Missing a dose of an antiseizure medicine can increase the risk of having a seizure, although a seizure is not guaranteed after one missed dose. The risk differs between individuals.
The NHS Specialist Pharmacy Service notes that regular use of antiseizure medicines is particularly important for people with epilepsy because missing a dose could trigger a seizure.
Other factors can also contribute to breakthrough seizures. These can include lack of sleep, stress, illness, alcohol, and other individual seizure triggers.
Therefore, if you miss Keppra, it is important to follow the missed-dose instructions provided for your medicine rather than assuming that everything will be fine or taking extra medicine.
Possible Effects of Missing Keppra
A missed dose does not necessarily cause a specific set of side effects. Instead, the main concern is a loss of seizure control.
Possible consequences include:
- Breakthrough seizure
- Increased seizure activity
- Return of symptoms that were previously controlled
- Anxiety about having a seizure
- Injury resulting from a seizure
Some people may not notice anything after missing a single dose.
That does not mean missed doses are harmless. Repeatedly missing medication can make seizure control more difficult.
What Is a Breakthrough Seizure?
A breakthrough seizure is a seizure that occurs even though a person has been receiving treatment intended to control seizures.
Missing an antiseizure medicine can be one possible trigger.
The type of seizure a person experiences depends on their epilepsy. Some people may have brief periods of altered awareness, while others may experience shaking or loss of consciousness.
If you have epilepsy, you should know your usual seizure pattern and have a plan for what family members or caregivers should do if a seizure occurs.
What Should You Do If You Miss a Dose of Keppra?
The instructions provided by the NHS for levetiracetam are straightforward.
If you remember that you missed your dose, take it as soon as you remember unless it is nearly time for your next dose. If the next dose is nearly due, skip the forgotten dose and continue with your normal schedule.
Do not take two doses together to compensate for the missed dose.
However, individual prescriptions can differ. If you are unsure whether you should take the missed dose, contact your pharmacist, doctor, or epilepsy specialist.
This is particularly important if you have missed more than one dose.
What If You Miss More Than One Dose of Keppra?
Missing several doses can be more concerning than missing one dose because you may spend a longer period with less medication available to control seizure activity.
Do not attempt to compensate by taking several tablets at once.
Instead, contact your healthcare professional for instructions about restarting your regular schedule.
If you have completely run out of Keppra, contact your pharmacy or prescribing healthcare professional as soon as possible. Avoid intentionally stopping treatment simply because you cannot obtain your normal supply.
Suddenly stopping levetiracetam can result in uncontrolled seizures. The FDA specifically advises patients not to stop levetiracetam without first discussing it with a healthcare professional.
Can You Take Two Keppra Doses Together?
Generally, no.
Taking extra Keppra to compensate for a missed dose can increase the amount of medicine in your body and may increase the chance of side effects.
The NHS specifically says not to take two doses to make up for a missed levetiracetam dose.
If you accidentally take more Keppra than prescribed, contact a pharmacist or healthcare professional for advice.
Does Missing Keppra Cause Withdrawal Symptoms?
Missing one dose does not necessarily cause classic withdrawal symptoms.
The bigger concern is the return or worsening of seizure activity because the medicine is no longer being taken as prescribed.
Stopping levetiracetam suddenly can result in uncontrolled seizures, which is why treatment should not be stopped without medical guidance.
If you want to stop Keppra because of side effects or another concern, speak with your doctor. They can determine whether the medicine should be changed, reduced, or stopped gradually.
Does Missing Keppra Make You Feel Different?
Some people may not notice any immediate change after missing a single dose.
Others may notice symptoms related to their underlying seizure disorder or may experience anxiety because they know they missed medication.
It is important not to assume that feeling normal means there is no risk. Keppra works to prevent seizures, and its effect cannot always be judged by how you feel from one hour to the next.
Following your prescribed schedule is therefore more important than waiting for symptoms.
Why Is Taking Keppra on Time Important?
Keppra is intended to be taken regularly.
Taking it around the same time each day helps maintain the treatment routine and makes it easier to remember doses. The NHS recommends taking levetiracetam at the same time each day.
If your prescription requires twice-daily dosing, maintaining the recommended spacing between doses is also important.
You can make remembering easier by:
- Setting a phone alarm
- Using a medication reminder app
- Keeping the medicine in an appropriate, consistent location
- Using a pill organizer when suitable
- Connecting the dose with an everyday routine
- Asking a family member or caregiver to help with reminders
If you regularly forget your medicine, tell your doctor or pharmacist. They may be able to suggest practical ways to make your treatment easier to follow.
What If You Vomit After Taking Keppra?
If you vomit shortly after taking Keppra, do not automatically take another dose.
Whether another dose is appropriate depends on how soon you vomited, the formulation you are taking, and whether the medication was absorbed.
Contact your pharmacist or healthcare professional for specific instructions rather than taking an additional dose on your own.
This is especially important if you have a history of frequent seizures.
What If You Cannot Get Your Keppra?
Do not simply skip your medication because your prescription has run out.
Contact your pharmacy or prescribing healthcare professional as soon as possible. Some pharmacies may be able to help with an emergency supply depending on local rules and your circumstances.
If you are traveling, it can be helpful to carry enough medication for the trip plus an appropriate backup supply.
Keeping medication in its original labeled packaging can also make it easier to explain your prescription if you need assistance away from home.
What Happens If You Stop Keppra Suddenly?
Stopping Keppra suddenly can be dangerous for people taking it to control seizures.
The FDA warns that stopping levetiracetam without medical advice can result in uncontrolled seizures.
Even if you have not experienced a seizure for a long time, that does not necessarily mean the medicine can be stopped safely.
If you want to stop Keppra because of side effects, cost, pregnancy concerns, or another reason, discuss the situation with your healthcare professional first.
When Should You Seek Emergency Help?
A missed dose itself does not always require emergency treatment.
However, emergency medical help is needed for certain seizure situations.
For example, seek emergency assistance if a seizure lasts longer than the emergency threshold provided in your seizure action plan, if seizures occur repeatedly without recovery, or if the person is seriously injured or having difficulty breathing.
If you have epilepsy, ask your healthcare professional what your personal emergency seizure plan should be.
How Can You Prevent Missing Keppra?
Creating a consistent routine can make missed doses less likely.
Try taking your medicine at the same time every day and setting an alarm before each dose.
A pill organizer can also help you see whether you have already taken a dose.
If you frequently forget medication, don’t simply accept it as unavoidable. Tell your doctor, pharmacist, or epilepsy nurse. They may be able to suggest a routine that fits better with your daily activities.
It can also help to keep track of seizures and missed doses. A seizure diary can show whether changes in medication timing are associated with changes in seizure activity.
Common Side Effects of Keppra
It is important to distinguish between the effects of missing Keppra and the side effects caused by taking Keppra.
Common side effects of levetiracetam can include sleepiness, tiredness, dizziness, headache, nausea, vomiting, tremor, agitation, irritability, and difficulty controlling body movements.
Some people also experience changes in mood or behavior.
If side effects are bothering you, talk with your healthcare professional rather than skipping doses on your own.
Frequently Asked Questions
Can missing Keppra make you feel sick?
Missing a dose does not usually cause a specific illness-like reaction. The main concern is reduced seizure control, although some people may notice symptoms related to their underlying seizure condition.
How long after missing Keppra does seizure risk increase?
There is no specific time that applies to everyone. The effect depends on the prescribed dose, formulation, individual metabolism, and how long the dose has been missed.
Can I take my next Keppra dose early?
Do not change your dosing schedule on your own. Follow the instructions provided for your prescription or ask your pharmacist what to do after a missed dose.
What happens if I accidentally take Keppra twice?
Taking an extra dose can increase the risk of adverse effects. Contact your healthcare provider, pharmacist, or local poison control service for advice rather than taking additional medication.
Can missing Keppra cause headaches?
A headache after missing a dose can occur for different reasons, but it should not automatically be assumed to be caused by the missed Keppra dose. If headaches are severe or unusual, seek medical advice.
Can missing Keppra cause mood changes?
Mood or behavioral changes can occur with levetiracetam, but a missed dose itself is not necessarily the cause. New or severe changes in mood or behavior should be discussed with a healthcare professional.
Should I take Keppra if I cannot remember whether I already took it?
Avoid automatically taking another dose because you are unsure. Check your medication organizer or records if possible, and contact your pharmacist or healthcare provider for guidance.
Can missing Keppra cause breakthrough seizures?
Yes. Missing an antiseizure medication can reduce seizure protection and may increase the possibility of a breakthrough seizure, although it does not mean one will definitely occur.
What should I do if I miss Keppra while traveling?
Follow the missed-dose instructions for your specific prescription and avoid taking extra doses to compensate. Keeping medication in your carry-on and using phone reminders can help prevent missed doses while traveling.
Can I stop taking Keppra if I have not had a seizure for a long time?
No. Being seizure-free does not necessarily mean the condition has gone away. Stopping Keppra suddenly can worsen seizure control, so any change should be discussed with your healthcare provider.
Conclusion
The main concern when you miss a dose of Keppra is not usually a new medication side effect. It is the possibility of reduced seizure control.
Missing one dose does not guarantee that a seizure will occur, but it can increase the risk of a breakthrough seizure. This is why levetiracetam should be taken consistently as prescribed.
If you forget a dose, follow the instructions provided with your prescription. For standard levetiracetam guidance, the NHS recommends taking the missed dose when you remember unless the next dose is nearly due. If it is nearly time for the next dose, skip the forgotten dose and return to your normal schedule. Do not take two doses together.
If you miss multiple doses, frequently forget your medication, run out of Keppra, or want to stop taking it, contact your doctor or pharmacist for individualized advice.
