Yes, you can crush Keppra tablets, but only certain formulations
Keppra (levetiracetam) comes in multiple forms, and whether you can crush it depends on which one you have. The when ready-release tablet can be crushed and mixed with liquid or soft food. The extended-release tablet cannot be crushed — it must be swallowed whole to work properly. If you cannot swallow tablets, your doctor or pharmacist can switch you to a liquid version or when ready-release tablets that you can crush.
Crushing a tablet changes how fast the medication enters your bloodstream. An when ready-release tablet releases the drug quickly whether you swallow it whole or crushed. An extended-release tablet is designed to release the drug slowly over many hours, and crushing it destroys that coating, causing too much medication to enter your system at once. This can cause side effects or reduce how well the medication works.
Before you crush any Keppra tablet, check the label or call your pharmacy. The label will say "extended-release" or "ER" if you cannot crush it. If you are unsure, do not crush it — ask your pharmacist which form you have and what your options are.
Key Takeaways
- when ready-release Keppra tablets can be crushed and mixed with food or liquid without losing effectiveness.
- Extended-release Keppra tablets must be swallowed whole; crushing them causes too much drug to release at once and can be unsafe.
- Your pharmacy label will indicate whether your tablets are extended-release or when ready-release.
- If you cannot swallow tablets, ask your pharmacist about switching to liquid Keppra or when ready-release tablets you can crush.
- Crushing a tablet without knowing which type you have can change how the medication works in your body.
How to crush Keppra safely if your tablets allow it
If you have confirmed that your Keppra is when ready-release, use a pill crusher or mortar and pestle to break the tablet into powder. A pill crusher is a small handheld device sold at most pharmacies for a few dollars. Place the tablet inside, close the lid, and turn the handle until the tablet becomes powder.
Mix the powder when ready with a small amount of soft food — applesauce, pudding, yogurt, or mashed potatoes work well — or stir it into a glass of water or juice. Swallow the mixture right away. Do not let it sit, because the powder can separate or clump. If you are mixing with food, make sure you eat or drink all of it so you get the full dose.
Wash your hands after handling the powder. If you are pregnant or planning to become pregnant, wear gloves when crushing tablets, because levetiracetam can pass through skin in small amounts.
Why extended-release tablets cannot be crushed
Extended-release tablets have a special coating that dissolves slowly in your stomach and intestines. This coating releases a small amount of medication over 12 or 24 hours, depending on the formulation. When you crush the tablet, you destroy the coating and expose all the medication at once.
Taking all the medication at once can cause dizziness, drowsiness, coordination problems, or other side effects. It can also make the medication less effective at controlling seizures because the levels in your blood spike and then drop instead of staying steady. For seizure control, steady levels matter more than high levels.
If your prescription is extended-release and you have trouble swallowing, do not try to work around it by crushing. Tell your doctor or pharmacist instead. They can prescribe when ready-release tablets or liquid, which are designed to be taken multiple times a day and will work just as well.
Liquid Keppra as an alternative to crushing tablets
Keppra liquid (oral solution) comes in a concentration of 100 milligrams per milliliter. You measure it with a syringe or dosing cup and swallow it or mix it with a small amount of liquid. The liquid tastes bitter, so many people mix it with juice or another flavored drink to make it easier to take.
Liquid Keppra works the same way as when ready-release tablets — it releases the medication quickly and reaches its peak level in your blood within an hour. Your doctor will prescribe the same total daily dose whether you take tablets, crushed tablets, or liquid, but the liquid form lets you adjust the dose more precisely if needed.
Liquid Keppra costs more than tablets at most pharmacies, but insurance often covers it if you have a medical reason for not being able to swallow tablets. Ask your pharmacist whether your insurance will cover the liquid form before you switch.
When to talk to your doctor or pharmacist about changing your form
If you have trouble swallowing tablets, have difficulty chewing, or care for someone who does, tell your prescriber before you try to crush anything. They may have already prescribed when ready-release tablets that are safe to crush, or they may recommend switching to liquid. If you have a feeding tube, your doctor needs to know that too, because some forms of Keppra work better through tubes than others.
If you are taking other medications, mention that when you ask about crushing or switching forms. Some drugs interact differently depending on how fast they are absorbed. Your pharmacist can check for interactions and make sure a different form of Keppra will not cause problems with your other prescriptions.
If you have already crushed an extended-release tablet by accident, do not panic. One dose is unlikely to cause serious harm, but call your pharmacist or poison control to be sure. They can tell you what to watch for and whether you need to do anything else.
Reading your Keppra label to know which form you have
Your pharmacy label will list the medication name, dose, and form. Look for these words:
- when ready-release: The label says "Keppra" or "levetiracetam" with no other descriptor, or it says "when ready-release" or "IR".
- Extended-release: The label says "Keppra XR" or "levetiracetam ER" or "extended-release".
If the label is unclear, do not guess. Call your pharmacy and ask the pharmacist to tell you the form over the phone. They can also tell you whether that form can be crushed and what your options are if you need a different form.
If you pick up a new prescription and the label looks different from your last one, ask the pharmacist whether anything has changed. Sometimes insurance or supply issues cause a pharmacy to switch you to a different manufacturer or form without telling you first.
Frequently Asked Questions
What happens if I accidentally crush an extended-release Keppra tablet?
One crushed extended-release tablet is unlikely to cause serious harm, but you should contact your pharmacist or poison control to report it. They can advise you based on your dose and medical history. You may experience dizziness or drowsiness, but these usually pass within a few hours. Do not crush extended-release tablets on purpose.
Can I mix crushed Keppra with hot food or drinks?
Yes, you can mix crushed when ready-release Keppra with warm or hot food and drinks. Heat does not break down levetiracetam. However, avoid very hot liquids right before or after taking the dose, because heat can increase how fast your stomach absorbs the medication and may cause side effects.
Does crushing Keppra change how long it takes to work?
Crushing an when ready-release tablet does not change how long it takes to work — it still reaches peak levels in your blood within about an hour. Extended-release tablets are designed to work over 12 or 24 hours, so crushing them changes the timing and can make them less effective for seizure control.
Can I split a Keppra tablet instead of crushing it?
You can split an when ready-release tablet if it has a score line (a groove down the middle), and your pharmacist confirms it is safe to do so. Extended-release tablets should never be split or crushed. If you need a lower dose, ask your pharmacist whether splitting is an option or whether you should switch to a different strength.
Is there a way to make liquid Keppra taste better?
Liquid Keppra is bitter and hard to mask. Mixing it with strong-flavored juice like grape or cherry juice helps. Some people add a small amount of honey or syrup, though you should check with your pharmacist first if you are diabetic or have other health conditions. Drinking it quickly through a straw can also reduce the taste.
