2. Approved and off-label uses of Keppra-XR (levetiracetam)
2.1 US FDA approved use(s)
XR: as an add-on for partial onset seizures. IR & injection: add-ons for partial & generalized seizures, and for JME.
2.2 Popular off-label uses
Using Keppra by itself for partial & generalized seizures and JME. Absence seizures, seizures and other damage caused by traumatic brain injury, Lennox-Gastaut syndrome, and various other forms of epilepsy and seizure disorders. Like most AEDs Keppra is used off-label to treat migraines, neuropathic pain, bipolar disorder, anxiety disorders, and substance abuse/addictions.

3. Keppra-XR’s (levetiracetam’s) Pros and Cons
3.1 Pros
Low side effect profile. As in fewer side effects than the placebos in several of the clinical trials. Much less chance of your flipping out on it when compared to other anticonvulsants (E.g. Keppra: 10% of epileptics with previous histories of psychiatric or serious epileptic flippage had issues. Topamax: 24% of similar people had issues.) Tends to make people smarter, not dumber like most anticonvulsants. Even people starting with learning disabilities can get a bit of a boost. Also, unlike many anticonvulsants it’s so easy on your liver you can take it after a freaking liver transplant! It starts working right away, and many people can start at or near the therapeutic dose if required-it was designed that way. One researcher describes it as having, “close to ideal pharmacokinetic properties.”
3.2 Cons
A lot of the side effects it does have are psychiatric. Reports from the field (a.k.a. anecdotal evidence) suggest the most common are the deep, sometimes suicidal depression. Another favorite is the Keppra rage, although this one seems to be overhyped, and the XR version may have dealt with that for many people in any event. Far less frequent, but still reported, are hallucinations - one woman I know with epilepsy had deep philosophical conversations with a ghost every night. And there’s this case report of a kid getting a bit psychotic on Keppra. Those kind of suck-especially when no one bothers to warn you that they might happen.
3.3 Interesting stuff your doctor probably didn’t tell you
Keppra doesn’t mess with, like, anything. In that it has practically no drug-drug interactions. That in and of itself is pretty interesting. Girls get more bang for their buck than boys with Keppra. Per the PI sheet women absorb 20% more of Keppra than men do. Keppra is by far the worst tasting pill on the market. Everyone who whines about how bad Lamictal tastes should lick a split Keppra. Then a split Topamax. Topamax’s taste warrants a mention in its PI sheet (although it turns out you’re not supposed to split Topamax because that hoses its rate of absorption, and isn’t really about the taste), and Keppra tastes even worse. All the other super interesting stuff is really geeky and belongs on other pages

4. Keppra-XR’s (levetiracetam’s) Side Effects
4.1 Typical side effects
Like most AEDs: sleepiness, headache, and dizziness/vertigo. What most crazy meds have as uncommon-to-rare, but are common side effects for Keppra: Muscle weakness and various kinds of infections-rhinitis, pharyngitis, sinusitis, and assorted nose problems.
4.2 Uncommon side effects
The mood problems-depression, psychosis, hostility, anxiety in various forms (I know, it’s supposed to be good for anxiety. But yet…drugs are weird…). Appetite changes one way or another. Paresthesia, aka that fun tingling in your extremities like Topamax does.
4.3 Freaky rare side effects
Peace-Love-and-Fluffy-Bunnies-Not-Manic-Just-Happy! OK, so Kassiane may have been the only one who got that for very long. Fungal infection. Gingivitis. The personal hygiene supply companies have a big market with people taking anticonvulsants.

5. How to take and stop taking Keppra-XR (levetiracetam)
5.1 How to take Keppra-XR
According to UCB you can start Keppra XR at 1000mg once a day and that’s it, sort of like Invega. They said the say thing about the immediate-release version as well, although with two 500mg doses. Although 500mg is the low-end of the therapeutic range. If you haven’t achieved symptom control, or you lose symptom control, your doctor may increase your dosage by 1000mg a day (taken once a day for KeppraXR and two 500mg doses for immediate-release Keppra) each week until you hit the maximum recommended dosage of 3000mg a day.
Guess what? I disagree.
UCB makes 250mg tablets for a reason, and Keppra immediate-release Keppra is really easy to split in half. So 500mg a day is probably a much better place to start. Hell, they don’t even make a 1000mg XR tablet!
And one week means seven days, not five.
Even though the XR is supposed to be once-a-day dosing and the IR twice-a-day, you may want to consider three-times-a-day (TID) dosing for IR and twice-a-day (BID), maybe even TID dosing to deal with any psychiatric side effects.
5.2 How to stop taking Keppra-XR
Slowly, unless being on Keppra is sucking serious ass. And this is why I don’t like starting a med at a therapeutic dose. OK. End soapbox. Generally, the way you went up—was it in 250mg increments, 500mg increments? Please say it wasn’t in 1000mg increments. How you went up on Keppra is how you should go down from Keppra —500 to 250 every 5 to 7 days.

6. When will Keppra-XR (levetiracetam) start working?
6.1 How long until Keppra-XR starts working
Not very. Like, as in two days not very. Even for refractory epilepsy Keppra can start working in one day.
6.2 Chances of Keppra-XR working
As an add-on for epilepsy, pretty good. About half the people who take it have their seizures reduced by at least 50%, and most of them keep taking it after three years.
Where Keppra really shines is for people with refractory (otherwise uncontrollable) epilepsy. The chances of working are almost as good: around 40% of people who take it have their seizures reduced by half, and some become seizure-free.

7. What Keppra-XR (levetiracetam) is best known for
Being the AED that will either fix you when nothing else can, or kill you because it’ll make you suicidally depressed and/or so enraged at the world that you’ll die because half-a-dozen cops had to tase you.

8. Keppra-XR’s (levetiracetam’s) half-life & how long until it clears your system
Half-lives IR: 6 to 8 hours, XR: 7 hours (BFD). Clearance: 1–2 days. It goes in fast, it goes out fast.

9. How Keppra-XR (levetiracetam) works (the best current guess at any rate).
You know how very few AEDs work the same way? Keppra is way more different than all of them. It binds to synaptic vesicle protein 2A (SVP2A) ligands (in English: reduces whatever the hell neurotransmitters or something else interacts with your brain via that stuff) and by doing so stabilizes any imbalance of the potassium and calcium voltage channels. This happens mostly in the hippocampus and amygdala, the latter of which explains the profound mood effects.

10. Comments
Keppra, Keppra, how I love my Keppra. My favorite anticonvulsant ever, and I’ve been on quite a few. Not only was my refractory epilepsy controlled for the first time ever, but Keppra made me happy. Yes, you read that right. Happy. Maybe that’s the effect of dekindling. I don’t know. But I was really cheerful, and my general anxiety was really low-OCD was bad, like, pull off the keys off the keyboard bad, but I can live with that. I was sleeping. And I got back cognitive skills I lost in the car accident I was in back in March 2005 - complex things like adding and subtracting 2 digit numbers so I don’t need to ask the bank people do to it. Keppra is brain miracle in a little yellow pill.
It appears that, like many anticonvulsants, if what Keppra does is what you need, then you don’t get the cognitive side effects, only for this med those side effects are psychiatric not “me feel stupid.” Or that could be me talking out my ass again.
If Brain/Pain Doctor Of Choice is suggesting you try Keppra it’s worth a shot; especially if someone is around to make sure you don’t completely flip your shit. Based on everything on various support forums, it’s a med that either you love or you hate.

Know your sources!
Nobody on this site is a doctor, therapist, or a pharmacist. We don’t portray them either here or on TV. Only doctors can diagnose and treat an illness. Some doctors tend to get pissed off by patients who know too much about medications, so tread lightly when and where appropriate. Diagnosing yourself from a website is like defending yourself in court, you suddenly have a fool for a doctor. Don’t be a cyberchondriac, thinking you have every disease you see a website about, or that you’ll get every side effect from every medication*. Self-prescribing is as dangerous as buying meds from fraudulent online pharmacies that promise you medications without prescriptions.
All information on this site has been obtained through our personal experience and the experiences family, friends, what people have reported on various reputable sites all over teh intergoogles, the medications’ product information / summary of product characteristic (PI/SPC) sheets, and from sources that are referenced throughout the site. As such the information presented here is not intended as a substitute for real medical advice from your real doctor, just a compliment to it. You should never, ever, replace what a real doctor tells you with something from a website on the Internet. The farthest you should ever take it is getting a second opinion from another real doctor. Educate yourself - always read the PI/SPC sheet or patient information leaflet (PIL) that comes with your medications and never ever throw them away.

We like them, or they’re paid advertisements, or they’re something else we think you should read to help you make an informed decision about a particular med.

Very little information about visitors to this site is collected or saved. From time to time I look at search terms used and which pages they bring up in an effort to make the information I present more relevant. And the country of origin, just because I’m geeky like that.

Or the rights to the drug were sold to another company. And any or all of the companies involved may have changed their names.
