[ARTICLE] Dramatic Weight Loss with Levetiracetam – Full Text

Summary

Background: Levetiracetam is considered a “weight-neutral” drug. We report 19 cases of significant weight loss associated with levetiracetam at a dose ranging from 500 to 2000 mg/day.

Methods: The population was divided into two groups. Group 1 includes patients in whom levetiracetam was the only possible cause of weight loss and Group 2 those in whom other factors may have played a role. Similar cases reported by the French national drug safety center were added (Group 3).

Results: Group 1 included 9 females and 3 males (weight loss ranging from 8.1% to 28.6%). Three patients had levetiracetam in monotherapy. Prior levetiracetam only three were overweight. One patient was hospitalized for a thorough assessment of weight loss. Seven patients reported reduced caloric intake due to decreased pleasure with food. The other five did not report any changes in feeding behavior. Group 2 included seven females with a weight loss ranging from 10% to 26.6%. One patient was on topiramate since two years prior to levetiracetam. Weight loss started with the introduction of levetiracetam. In 4 patients, there was a decreased dosage or cessation of a previous drug known to produce weight gain in some cases simultaneously to the introduction of levetiracetam, but in two of these patients these drugs had not produced any weight gain. Group 3 included only two patients (weight loss: 7 and 20 kg).

Conclusions: This study provides evidence that levetiracetam can cause significant weight loss. Women are at higher risk while initial weight is not a factor.

Levetiracetam (LEV) is an antiepileptic drug with a broad clinical spectrum effective in focal epilepsy as well as in idiopathic generalized epilepsy (Grunewald, 2005Di Bonaventura et al., 2005). The majority of adverse effects are of mild to moderate severity, the most commonly reported being asthenia, somnolence, headache, and dizziness (Genton et al., 2006). Less frequent events that may also occur are anorexia, nausea, dry mouth (Biton, 2002) and behavioral and psychiatric events (Dinkelacker et al., 2003Genton et al., 2006).

LEV is considered “weight-neutral” (Gidal et al., 2003Briggs and French, 2004). However, weight loss is listed in a study comparing LEV in adult vs ageing patients (Cramer et al., 2003) and four cases of considerable weight loss have been published with LEV used in cotherapy at a dose ranging from 2000 to 3000 mg/day (Hadjikoutis et al., 2003). In the light of our recent clinical experience, we report 19 cases of weight loss associated with LEV but at lower doses and in monotherapy in three patients. These 19 patients were divided in two soubgroups, with LEV as the likely contributing factor vs cases with confounding variables.[…]

Keppra

The dangerous drug attorneys at the Law Offices of Gregory Krasovsky can provide legal advice and representation to individuals and families considering pursuing a Keppra lawsuit. In order for a plaintiff to secure a maximum settlement in litigation of a Keppra claim, regardless of whether in an individual lawsuit or in a class action lawsuit, it is crucial that the law firm representing you have a competent and experienced team of Keppra lawyers to guide you through all of the legal hurdles as well as direct you to sufficient funding (litigation funding or legal finance) to cover pharmaceutical litigation costs. Contact  a Keppra attorney today to schedule a free consultation and take your first step to obtaining compensation for losses caused by Keppra side effects.

Keppra, which is generically known as Levetiracetam, is an anticonvulsant drug used to treat epilepsy. Keppra was originally manufactured and marketed by UCB Pharmaceuticals Inc., but now it is available as a generic and is manufactured by a number of firms. Unfortunately, Keppra has a number of serious side effects that can, at times, outweigh its benefits for people who are suffering from epilepsy. Some of the most serious Keppra adverse effects include suicidal tendencies and birth defects.

There are many Levetiracetam side effects. These include, but are not limited to, the following:

  • Suicidal Ideation
  • Suicidal Tendencies
  • Suicide
  • Headache
  • Unsteady Walk
  • Depression
  • Hallucinations
  • Fever
  • Sore Throat
  • Mood Changes
  • Changes in Skin Color
  • Anxiety
  • Birth Defects

A 2005 Food and Drug Administration (FDA) study of suicidal ideation in relation to epilepsy drugs has indicated that people taking those drugs, such as Keppra, are twice as likely to suffer from suicidal thoughts as are those who have not been taking these drugs.

Unlike many other drugs, such as Wellbutrin, people taking Keppra are likely to experience suicidal ideation regardless of what age group they might happen to fall into. The aforementioned study tracked almost 30,000 people, and the rick of suicide was spread fairly evenly across the population. Of the 28,000 people who had taken Keppra in this study, four of them had actually committed suicide. These unfortunate incidents serve to confirm the danger of this unsafe drug.

Although Keppra’s ability to cause birth defects is still under investigation, there is some amount of evidence that seems to confirm that Keppra is more harmful to unborn babies than was previously thought. Currently, the FDA has placed Keppra in the Category C for pregnancy, which indicates that there is little human risk. However, AdverseEvents, Inc. believes that Keppra should perhapd be in Category D, which indicates that a significant enough risk to pregnancy exists.

Keppra is similar to another prototypical nootropic drug called piracetam. Keppra is also thought to be a possible treatment for Tourette syndrome, autism, bipolar disorder, and anxiety disorder.

The attorneys at this Keppra law firm believe that drugs should not cause the same ailments that they are meant to cure. If you or your loved one has been injured as a result of taking Keppra, you might be entitled to compensation. Contact our attorneys today to schedule a free consultation.

[Abstract] Can High-Dose Levetiracetam Be Safe? A Case Report of Prolonged Accidental High-Dose Levetiracetam Administration and Review of the Literature

Levetiracetam is an antiepileptic drug that has been used both as adjunctive therapy and monotherapy in pediatric patients with epilepsy. We report a patient with cerebral palsy and epilepsy who took 200 mg/kg per day of levetiracetam for 55 days with no apparent adverse effects. Four other cases of accidental overdose were found in the literature; none of these was associated with any apparent adverse effects. These findings suggest that, in at least some cases, levetiracetam doses much higher than the recommended maximum of 60 mg/kg per day can be administered without apparent adverse effects.

Newer Epilepsy Drugs May Be Safer During Pregnancy

Small British study says two drugs don’t harm a child’s mental development, but popular older one does

THURSDAY, Sept. 1, 2016 (HealthDay News) — Women who take the new epilepsy drugs levetiracetam and topiramate during pregnancy don’t run the risk of harming their infant’s mental development, British researchers report.

But the commonly prescribed anti-seizure drug valproate was linked with lower IQs in children, especially when taken at higher doses, researchers say.

“The treatment of epilepsy in women who are considering a pregnancy or are pregnant involves optimizing the health of the mother as well as keeping the risk to the fetus as low as possible,” said lead researcher Rebecca Bromley, a research fellow at the Institute for Human Development at the University of Manchester.

In the study, children exposed to levetiracetam (Keppra) or topiramate (Topamax) in the womb did not differ from children not exposed to these drugs. And they had better outcomes than the children exposed to valproate (Depakote) in terms of their IQ, thinking and language skills, Bromley said.

“These data can be used by doctors and women to help them make their decisions about which medication is best for them,” she added.

For the study, Bromley and her colleagues used the U.K. Epilepsy and Pregnancy Register to identify 171 women with epilepsy who had a child between 5 and 9 years old. During their pregnancy, 42 of the women took levetiracetam, 27 took topiramate, and 47 took valproate, the researchers said.

Bromley’s team compared the women with epilepsy with 55 women who did not take epilepsy drugs during pregnancy. The children had their IQ measured and took tests on verbal and nonverbal comprehension and how fast they could process visual information.

The researchers found that children of women who took levetiracetam or topiramate did not have lower IQs or other thinking-skill problems, compared with kids of mothers who did not take these drugs, no matter what dose of these drugs were taken.

Children whose mothers took valproate, however, had the lowest IQs of the study, Bromley said. These kids scored, on average, 11 points lower on the IQ test.

Among children whose mothers took valproate, 19 percent had IQs lower than the average score of 100, compared with 6 percent among kids whose mothers did not take any epilepsy drugs during pregnancy, the researchers found.

Because the registry the researchers used does not include all women with epilepsy, the findings might not apply to all women with the conditions, Bromley noted. She also said that topiramate, one of the newer drugs, has been associated with an increased risk of birth defects, such as cleft lip and palate.

The study was funded by Epilepsy Research U.K. and the report was published online Aug. 31 in the journal Neurology.

Dr. Ian Miller is a pediatric neurologist and medical director of the comprehensive epilepsy program at Nicklaus Children’s Hospital in Miami. “This study means that we have a little bit more information for women who become pregnant while taking epilepsy medicines,” he said.

The exact risks of taking any medicine during pregnancy are very difficult to know, he added.

“As a result, many questions remain,” Miller said. “But this study gives doctors a reason to choose topiramate or levetiracetam, which did not show a measurable effect on the child’s development, rather than valproate, which did.”

Women who are on valproate because they already tried other medications and “moved on because those medications were less effective, will face some difficult decisions,” he said.

“Any woman of childbearing potential should discuss this aspect of their medical management with their doctor, especially in light of these new findings,” Miller added.

Highlights

  • We analyzed the adverse events (AEs) profile of levetiracetam with a meta-analysis.
  • A combined analysis of children and adults with any disease was performed.
  • The risk of withdrawals was higher for patients taking levetiracetam than placebo.
  • A general good tolerability profile of levetiracetam has been evidenced.
  • We did not find a clear dose–response relationship for the significant AEs.

Abstract

Purpose: To analyze the adverse events (AEs) significantly associated with levetiracetam (LEV) therapy through a meta-analysis of all available double-blind, randomized placebo-controlled trials (RCTs), performed in any age, gender, ethnic background and disease. General tolerability and study withdrawals due to AEs associated with LEV treatment were also investigated. In addition, a dose–effect responses relationship for all variables was assessed.

Methods: RCTs were identified searching Medline (PubMed), Embase and Cochrane CENTRAL for the words “Levetiracetam” and “randomized controlled trial”, with different search strategies, setting the limits “humans” and “English”. Very common and common AEs according to the summary of product characteristics were investigated. RevMan version 5.2 was used for the statistical analyses. Risk difference with 95% confidence intervals was used to investigate the association of any AEs and withdrawal with LEV.

Results: Twenty-six studies with 2832 patients were included in the RCTs analysis. Nasopharyngitis, somnolence, dizziness, nervousness/irritability and asthenia/fatigue were statistically significant associated with LEV. In addition, LEV was significantly associated with an increased risk of AEs-related withdrawals. No dose–response relationship was found for any of the assessed variables.

Conclusions: This first large meta-analysis suggests that participants were more likely to discontinue LEV than placebo.The AE profile confirmed that LEV is associated with few unfavorable sedative, vestibulocerebellar and behavioral effects, such as nervousness and irritability. However, there does not seem to be a clear dose–response relationship.

[WEB SITE] Do You Use Levetiracetam to Treat Status Epilepticus?

A Refresher: Treating Status Epilepticus in the ICU

I was working in the intensive care unit (ICU) the other night when I was called to the emergency department to see a patient who was reported to be in status epilepticus (SE). The patient had received several doses of lorazepam (Ativan®) and was loaded with intravenous levetiracetam (Keppra®). I hadn’t ever used levetiracetam for patients with SE before, so I went ahead and loaded the patient with fosphenytoin (Cerebyx®). I’d hardly call myself an expert in neurocritical care, so I figured it was time to go back and read about the management of SE in the ICU.

There’s no shortage of review articles out there, but I started with guidelines published by the Neurocritical Care Society in 2012.[1] Levetiracetam is on the list of agents recommended for emergent, urgent, and refractory treatment of SE. All levetiracetam recommendations are class IIb/level C (more data are needed, but treatment is not unreasonable based on consensus opinion, case reports, or standard of care).[1]

A quick look at the available references confirms that most are small case reports or observational case series. A recent review says that the practice of using levetiracetam shows promise—citing efficacy, safety, and tolerability across studies and one pilot study that compared levetiracetam to lorazepam.[2] They also noted that the Neurocritical Care Society guidelines list no serious adverse effects and minimal drug interactions. Perhaps levetiracetam is the ideal drug to use in the elderly and in the ICU.

To be clear, I’ll still be using lorazepam as my first line based on the results from the Veterans Affairs Status Epilepticus Cooperative Study Group.[3] It’s absolutely the best designed study on SE that we have. For urgent control, levetiracetam sure looks like a reasonable option when compared with fosphenytoin, which often causes hypotension.

Cost: A Reasonable Consideration

Of course, cost must be considered, and while I was unable to find a cost-efficacy analysis specific to SE treatment, studies looking at levetiracetam vs phenytoin for prophylaxis after traumatic brain injury clearly favored phenytoin.[4,5]

It’s not clear that these data can be readily generalized to SE treatment. In summary, for patients who are elderly, hemodynamically unstable, or on multiple medications, I’ll be using levetiracetam at the doses recommended in the recent guidelines.[1]

[ARTICLE] Post-traumatic epilepsy: current and emerging treatment options – Full Text

Abstract

Traumatic brain injury (TBI) leads to many undesired problems and complications, including immediate and long-term seizures/epilepsy, changes in mood, behavioral, and personality problems, cognitive and motor deficits, movement disorders, and sleep problems.

Clinicians involved in the treatment of patients with acute TBI need to be aware of a number of issues, including the incidence and prevalence of early seizures and post-traumatic epilepsy (PTE), comorbidities associated with seizures and anticonvulsant therapies, and factors that can contribute to their emergence.

While strong scientific evidence for early seizure prevention in TBI is available for phenytoin (PHT), other antiepileptic medications, eg, levetiracetam (LEV), are also being utilized in clinical settings. The use of PHT has its drawbacks, including cognitive side effects and effects on function recovery. Rates of recovery after TBI are expected to plateau after a certain period of time. Nevertheless, some patients continue to improve while others deteriorate without any clear contributing factors.

Thus, one must ask, ‘Are there any actions that can be taken to decrease the chance of post-traumatic seizures and epilepsy while minimizing potential short- and long-term effects of anticonvulsants?’ While the answer is ‘probably,’ more evidence is needed to replace PHT with LEV on a permanent basis. Some have proposed studies to address this issue, while others look toward different options, including other anticonvulsants (eg, perampanel or other AMPA antagonists), or less established treatments (eg, ketamine). In this review, we focus on a comparison of the use of PHT versus LEV in the acute TBI setting and summarize the clinical aspects of seizure prevention in humans with appropriate, but general, references to the animal literature.
