Dry mouth. Assuming patients with chronic medical conditions (e.g. An authorless report from 2005 stated that “the adverse effects profile of pregabalin is similar to that of gabapentin” and includes mainly neurophysiologic reactions (dizziness and drowsiness). Additionally, long-acting pregabalin (controlled-release) is sold in 3 total dosing increments (82.5 mg, 165 mg, 330 mg) – whereas long-acting gabapentin (extended-release) is sold in 2 total dosing increments (300 mg and 600 mg). Due to its lower price, Gabapentin is the more attractive option between the two drugs. In response to the aforementioned secondary neurochemical actions facilitated by pregabalin and gabapentin: (1) inhibitory (GABAergic) neurotransmission increases; and (2) excitatory (glutamatergic) neurotransmission decreases. In summary, there are few studies that’ve attempted to compare the efficacy of pregabalin to that of gabapentin in the treatment of postherpetic neuralgia. Using studies in postherpetic neuralgia, the EC50 values of pregabalin and gabapentin were estimated to be about 4.21 mg/mL and 11.7 mg/mL, respectively. However, a few months ago I started to experience inter-dose withdrawal from the gabapentin and Lyrica, and it's getting worse. I've never tried pregabalin, only gabapentin but can say that according to the British National Formulary (BNF), the side effects are more or less the same. Researchers concluded that there’s a trend to suggest that adjunct pregabalin may be more effective than adjunct gabapentin in treatment of seizures. Gabapentin and Pregabalin for the Treatment of Anxiety Disorders. 2. The U.S. FDA-authorized medical uses of gabapentin (Neurontin) are limited to the 2 aforementioned conditions (postherpetic neuralgia and partial onset seizures). Although pregabalin and gabapentin share common secondary neurochemical actions, it remains unclear as to whether there’s a difference in respective magnitudes of their secondary neurochemical effects. In comparison, Schedule V substances like pregabalin can only be refilled a maximum of 5 times within 6 months before additional doctor appointments are needed for further refills. As off-label interventions, the only noteworthy difference between pregabalin and gabapentin is that gabapentin needs to be prescribed off-label to treat: diabetic neuropathic pain; fibromyalgia; and neuropathic pain associated with spinal cord injury. (2010) would’ve reported greater efficacy for pregabalin (relative to gabapentin) in the treatment of partial onset seizures, the findings would be difficult to trust. Standard-release gabapentin is available in capsules, tablets, and oral solution (3 formats) – whereas standard-release pregabalin is only available in capsules and oral solution (2 formats). Lexapro (Escitalopram) vs Zoloft (Sertraline): Extensive Comparison, Pregabalin (Lyrica) vs. Gabapentin (Neurontin). Pregabalin (brand name Lyrica) and gabapentin (brand name Neurontin) are both medications used to treat seizures, pain related to shingles, and certain other types of nerve pain. However, that’s not to say that gabapentin abuse isn’t risky. Blommel ML, Blommel AL. As a Schedule V substance, pregabalin (Lyrica): (1) has a lower abuse potential than Schedule IV substances; (2) has accepted medical uses in the U.S.; and (3) can lead to limited dependence (physical and/or psychological) if abused. This study provided Class II evidence to suggest that pregabalin and gabapentin do not differ in efficacy as adjuncts for the treatment of partial onset seizures. In the United States, pregabalin (Lyrica) and gabapentin (Neurontin) are both approved by the Food and Drug Administration (FDA) as standalone treatments in postherpetic neuralgia and as adjunct treatments in partial onset seizures. Hot flashes. FDA-approved uses: Though pregabalin (Lyrica) and gabapentin (Neurontin) are generally utilized interchangeably and are both approved by the U.S. FDA to treat postherpetic neuralgia and partial onset seizures, pregabalin is approved by the U.S. FDA to treat 3 conditions that gabapentin is not. You, as a reader of this website, are totally and completely responsible for your own health and healthcare. The gabapentin and Lyrica helped me deal with the post acute withdrawal symptoms from the Valium. Long-acting pregabalin is sold under the brand name Lyrica CR (pregabalin controlled-release) – and long-acting gabapentin is sold under the brand names Gralise (gabapentin extended-release) and Horizant (gabapentin enacarbil extended-release). Both drugs have been found to be useful for treating generalized anxiety disorder (GAD). That said, differences in the occurrence rates of side effects for pregabalin and gabapentin may be less significant than available medical literature suggests. For a full day of symptom management, pregabalin (Lyrica) generally requires twice-daily dosing (b.i.d.) Bar Ad V. Gabapentin for the treatment of cancer-related pain syndromes. ); (3) use of questionnaire data (questionnaires frequently yield unreliable data); (4) possibly-inaccurate estimations and calculations from researchers; (5) funding by Pfizer (a pharmaceutical company who stood to benefit financially from proving the superiority of pregabalin over gabapentin); and (6) the study was conducted and authored by Pfizer employees. Smith et al. Included below are summaries of studies in which the efficacies of pregabalin and gabapentin are discussed and/or compared for neuropathic pain and fibromyalgia. Summary: We compare the side effects and drug effectiveness of Gabapentin and Pregabalin. Lyrica and gabapentin are chemically related, but researchers do not know exactly how they work. Pregabalin and gabapentin are each manufactured in multiple formats and a variety of dosage increments. In 2017, the United Kingdom opted to modify the legal classification of pregabalin and gabapentin from standard prescriptions to “Class C” controlled substances. In this simulation model, each patient was randomly allocated an average pretreatment pain score (based on an 11-point visual analogue scale) using data from an actual distribution of pain levels reported in randomized, double-blind, controlled trials. “add-on”) to a first-line anticonvulsant. Although clinically-recommended dosages of pregabalin may yield greater abuse/addiction potential than clinically-recommended dosages of gabapentin, if the dosage of gabapentin is increased to a supratherapeutic level – it’s abuse/addiction potential likely exceeds that of pregabalin (at clinically-recommended dosages). If you have experience with the gabapentinoid medications – pregabalin (Lyrica) and gabapentin (Neurontin), leave a comment regarding whether you: (A) prefer one medication over the other OR (B) have no substantial preference for using one medication over the other. Alcohol withdrawal. incoordination), fatigue, nystagmus (involuntary eye movements), fever, nausea, vomiting, and hostility (as side effects). Lyrica [Package insert]. 32. Gabapentin and pregabalin primarily exert their activity by inhibiting the alpha 2 delta subunit receptors on voltage-gated calcium channels presynaptically, thereby reducing the release of stimulatory neurotransmitters. According to StatPearls, the average elimination half-life of pregabalin is 6.3 hours and the average elimination half-life of gabapentin is 6.5 hours (ranging from 5 to 7 hours). 300 mg/day of Lyrica vs. 1800 mg/day Neurontin) – whereas standard Neurontin capsules/tablets are cheaper than standard Lyrica capsules at low doses (100 mg/day of Lyrica vs. 600 mg/day of Neurontin). I was taking Lyrica and was still in pain, my doctor switched me to Gabapentin and at first I thought it was better. Common withdrawal symptoms associated with both pregabalin (Lyrica) and gabapentin (Neurontin) include: anxiety; cognitive impairment; depression; diarrhea; fatigue; flu-like symptoms; insomnia; mood changes; muscle aches; nausea; rebound symptoms (of the medical condition for which the gabapentinoid was prescribed); restlessness; and vomiting. 2012: Evaluation of efficacy and safety of gabapentin, duloxetine, and pregabalin in patients with painful diabetic peripheral neuropathy. Pregabalin maintains a ~90% bioavailability at high doses – whereas the bioavailability of gabapentin continues dropping with dose escalation. Previous post: Celexa (Citalopram) vs. Lexapro (Escitalopram): Which Is Better? Additionally, although pregabalin and gabapentin exhibit similar primary mechanisms of action, some studies suggest that pregabalin exerts nearly 6-fold the inhibition of α2δ subunit-containing voltage-dependent calcium channels (VDCCs) relative to gabapentin. An earlier systematic review by Smith et al. Individuals who solely require short-term symptom management might like the fact that gabapentin controls symptoms for a predictably brief duration (5 to 8 hours) – and then it wears off (such that users aren’t under its influence and/or enduring medication-related side effects all day). Despite the aforementioned findings (indicating that pregabalin might be superior to gabapentin in postherpetic neuralgia), there are some limitations that warrant discussion. 1,2 Pregabalin is the pharmacologically active S-enantiomer of 3-aminomethyl-5-methyl-hexanoic acid, and has a similar pharmacological profile to gabapentin. Asked 16 May 2014 by Savannity cats Updated 9 December 2020 (6 weeks ago) Topics lyrica, pain, fibromyalgia, gabapentin, side effect, neuropathic pain. Because the bioavailability of gabapentin decreases at high doses (minimizing odds of a euphoriant effect from abuse/misuse) whereas the high bioavailability of pregabalin is retained at all doses (increasing odds of a euphoriant effect from abuse/misuse). Gabapentin and pregabalin are drugs used to treat a range of symptoms caused by MS, such as nerve pain, spasticity and spasms.. Lyrica (Pregabalin) vs Gabapentin (Neurontin) Lyrica and Gabapentin are antiepileptic anticonvulsant drugs. Part of the swap is to see if pregabalin will be more effective for my pain and it's also to see if I will lose some of the fluid that I have retained with gabapentin. According to side effect data compiled by the FDA, pregabalin is more likely (than gabapentin) to cause: blurred vision, weight gain, difficulty concentrating, dry mouth, and increased appetite – and gabapentin is more likely (than pregabalin) to cause: ataxia, fatigue, nystagmus, fever, nausea, vomiting, and hostility. ); (3) potentially-inaccurate comparisons in potency of dosing (e.g. While gabapentin (GBP) and pregabalin (PGB) are both used to treat CS, equipoise exists. 4. Here we have listed the common similarities between the two drugs: They both are considered antiepileptic drugs; … One study developed a population pharmacokinetic model comparing pregabalin with gabapentin. gabapentin for one month, pregabalin for the second month, etc.). It is also understood that euphoria did not occur in clinical trials of gabapentin (yet euphoria occurred in clinical trials of pregabalin). The report further stated that pregabalin, analogous to gabapentin, can cause weight gain and peripheral edema in elderly persons. It was noted that the principal population at risk of gabapentinoid addiction consists of persons with a history of substance use disorders (especially opioid users and poly-drug users). According to U.S. FDA Access Data, the most common pregabalin (Lyrica) side effects include: dizziness, somnolence, dry mouth, edema, blurred vision, weight gain, difficulty concentrating, and increased appetite. Bockbrader HN, Wesche D, Miller R, Chapel S, Janiczek N, Burger P. A comparison of the pharmacokinetics and pharmacodynamics of pregabalin and gabapentin. Gabapentin and Pregabalin are drugs that are often mistaken as synonymous with each other. Online. Due to its lower price, Gabapentin is the more attractive option between the two drugs. (2011) involving 90 women with abdominal hysterectomy pain reported that pregabalin is associated with fewer dose-related adverse reactions than gabapentin. concluded that gabapentin appears efficacious in the management of fibromyalgia-related symptoms. Top. Since gabapentin is available as a low-cost generic (pregabalin is not) and is considered a “standard prescription” (pregabalin is a “Schedule V” substance), it would make sense for patients and practitioners to favor the use of gabapentin. Edema. That said, persons who only require intermittent or “as-needed” administration of gabapentinoids might actually prefer to use gabapentin instead of pregabalin on the basis of its shorter duration of action. Included below is a brief recap of similarities associated with pregabalin and gabapentin. conducted a meta-analysis indirectly comparing the efficacies of gabapentin (GPB); pregabalin (PGB); duloxetine (DLX); and amitriptyline (AMT) – in the treatment of diabetic peripheral neuropathic pain (DPNP). Pharmacokinetic studies suggest that pregabalin is absorbed quicker than gabapentin and reaches peak plasma concentrations quicker (within 1 hour) than gabapentin (within 3 to 4 hours). 5. In the same study, which of the above were found to be the most common adverse events for both pregabalin and gabapentin? conducted a study to assess the cost-effectiveness of pregabalin relative to gabapentin in the treatment of postherpetic neuralgia and peripheral neuropathic pain. Results of this simulation study suggested that pregabalin was more effective than gabapentin for the treatment of postherpetic neuralgia. Differences Between Lyrica (Pregabalin) and Gabapentin In the U.S., medicines containing gabapentin are approved to treat seizures, post-herpetic neuralgia, and restless legs syndrome. Furthermore, because gabapentin (as a standard prescription) is slightly easier to attain than pregabalin (a Schedule V substance), its misuse may be more common relative to the misuse of pregabalin. Antiepileptic and anticonvulsant drugs are used to treat epilepsy and seizures. Experiencing these effects may significantly increase risk of future abuse and addiction. As a result, both medications have received official approval from the U.S. FDA as interventions for postherpetic neuralgia. Noteworthy similarities between pregabalin and gabapentin include: drug classification; efficacy; elimination half-life; formatting; mechanism of action; medical uses; metabolism; side effects; and withdrawal symptoms. Because studies suggest that pregabalin might be more effective than gabapentin (but none suggest the opposite), the potentially-superior efficacy of pregabalin makes it favorable over the gabapentin. Hi Everyone. Similar to the findings by Bonnet and Scherbaum (2017), persons at highest risk for misusing gabapentin were individuals with histories of drug abuse. Since only Neurontin is available as a generic (gabapentin) which can be attained for a significantly lower cost than Lyrica, most would regard gabapentin as being significantly more cost-effective (until generic Lyrica i.e. The most useful data for comparing the head-to-head efficacies of pregabalin and gabapentin in the treatment of neuropathic pain were derived from a study by Devi et al. Limitations associated with this study include: (1) small sample size; (2) no transition from pregabalin to gabapentin (only from gabapentin to pregabalin); and (3) short duration (2 weeks). Deanne . The longer duration of action associated with pregabalin (8 to 14 hours) relative to gabapentin (5 to 8 hours) might be preferred by patients because symptoms can be managed throughout the day with less frequent dosing. New York, NY: Park-Davis, Division of Pfizer; December 2013. In addition to inhibiting α2δ-subunits of voltage-dependent calcium channels, pregabalin and gabapentin exhibit a host of similar (non-primary) neurochemical actions, including: glutamic acid decarboxylase (GAD) upregulation; cytosolic branched-chain aminotransferase (BCATc) competitive inhibition; GABA aminotransferase (GABA-T) inhibition; glutamate dehydrogenase (GDH) inhibition; neuropeptide (substance P and CGRP) modulation; NMDA receptor inhibition; neural connectivity modulation. A 30-day supply of Lyrica capsules at a dosage of 300 mg per day ranges in price from $442 to $471, whereas a 30-day supply of Neurontin capsules/tablets at a dosage of 1800 mg per day ranges in price from $911 to $975 – making Lyrica the significantly cheaper option. Despite differences between pregabalin and gabapentin in their respective FDA-approved medical uses, both medications are regularly utilized “off-label” to treat medical conditions for which their FDA-approvals are lacking. The researchers did state that pregabalin (Lyrica) appears slightly more addictive than gabapentin (Neurontin) in aspects such as: magnitude of behavioral dependence symptoms; transitions from prescription to self-administration; and durability of self-administration. Unless a large-scale, randomized controlled trial proves otherwise, pregabalin and gabapentin should be regarded by medical professionals as equally efficacious interventions for postherpetic neuralgia. These half-life figures suggest that pregabalin will remain in one’s system for ~1.44 days, and gabapentin will remain in one’s system for ~1.48 days – following discontinuation. Since pregabalin is significantly more bioavailable than gabapentin (especially at high doses), the former (pregabalin) may be safer, more tolerable, and/or more efficacious than the latter (gabapentin). There appears to be a modest difference in the average elimination half-life of pregabalin (~6.3 hours) relative to the average elimination half-life of gabapentin (~6.5 hours). Moreover, know that the prices of Lyrica (pregabalin) and Neurontin (gabapentin) may be subject to significant variation among retailing pharmacies. However, at higher dosages, brand name Lyrica capsules become notably cheaper than brand name Neurontin capsules/tablets. Restless leg syndrome (RLS). Horizant [Package insert]. There are a couple of important points to note. Gabapentin and pregabalin were significantly effective in reducing pain, however, gabapentin had fewer and less severe adverse events vs pregabalin. He is a Diplomate to the Academy of Integrative Pain Management, a Fellow to ACCP, ASHP, & FSMB, a member of several other professional organizations. In many of these variables, there aren’t clinically-significant differences between pregabalin and gabapentin. Robertson K, Marshman LAG, Plummer D, Downs E. Effect of gabapentin vs pregabalin on pain intensity in adults with sciatica: A randomized clinical trial. 150 mg pregabalin may be more potent than 600 mg gabapentin); and (4) competing interests (the meta-analysis was funded by Pfizer Inc., included data from 8 studies funded by Pfizer Inc., and authors of the study were Pfizer Inc. employees). What is neuropathic pain? 3. Arnold et al. Based on current knowledge of pregabalin and gabapentin pharmacodynamics, respectively, some may argue that these medications have zero clinically-relevant abuse liability or addiction potential. Dr. Fudin is a section editor for Pain Medicine & Co_Editor-A-Large for Practical Pain Management. Gabapentin (Neurontin) and Pregabalin (Lyrica) are indeed useful and even recreational drugs. From 1 April 2019, gabapentin and pregabalin have been reclassified as controlled drugs, leading to changes in how they are prescribed. Lyrica is the brand name for the drug pregabalin, and gabapentin is the name of the medication that is used in drugs such as Neurontin, Gralise, and Horizant. Lyrica vs. Gabapentin: Addiction and Dependence. Substantial shifts in the respective popularities of pregabalin and gabapentin would likely occur if: (1) pregabalin were reclassified as a “standard prescription” (rather than a “Schedule V” controlled-substance) OR (2) gabapentin were reclassified as a “Schedule V” controlled-substance (rather than a “standard prescription). For example, a simulation study (based off of magnitude of effect in clinical trials) suggested that pregabalin is likely more effective than gabapentin in the treatment of postherpetic neuralgia. Lyrica vs. Gabapentin for Anxiety. morning and evening) – rather than thrice per day (e.g. Ifuku M, Iseki M, Hidaka I, Morita Y, Komatus S, Inada E. Replacement of gabapentin with pregabalin in postherpetic neuralgia therapy. Pregabalin is estimated to take effect within 40 to 120 minutes of administration – and that gabapentin is estimated to take effect within 30 to 60 minutes of administration. 3. Gabapentin vs. Pregabalin: side effect and effectiveness comparison . Although the future popularity of pregabalin will likely eventually increase (when it becomes available as a generic), it’s unclear as to whether the future popularity of pregabalin will ever exceed that of gabapentin. Essentially, because the body cannot use a large percentage of high-dose gabapentin, the circulating excess (unused portion) could theoretically increase risk of adverse reactions and/or the severities of preexisting side effects. The cause of discontinuation symptoms (associated with pregabalin and gabapentin) is imbalanced physiology – attributable to physiology gradually transitioning from a gabapentinoid-adapted state to sober homeostasis. For this reason, the United States FDA has classified pregabalin (Lyrica) as a Schedule V substance – while gabapentin (Neurontin) remains available as a standard prescription. Although sensitivity analyses substantiated the findings of the base-case analysis, the sensitivity analyses did not find statistical significance between pregabalin and gabapentin. Log in or register to post comments; 17 Jan 2014 at 10:19 pm #2. This study was long-term (6-week baseline phase & 21-week treatment phase); large-scale (484 patients), and utilized randomization. Standard pregabalin is sold in 8 total dosing increments (25 mg, 50 mg, 75 mg, 100 mg, 150 mg, 200 mg, 225 mg, 300 mg) – whereas standard gabapentin is sold in 5 total dosing increments (100 mg, 300 mg, 400 mg, 600 mg, 800 mg). ): Several comparison studies (indirect simulation and direct) have suggested that pregabalin (Lyrica) might be superior over gabapentin (Neurontin) in efficacy. Pregabalin and gabapentin are often considered first-line treatments for various neuropathic pain syndromes, generally irrespective of cause, /contributor/jeffrey-fudin/2015/09/how-gabapentin-differs-from-pregabalin, Copyright Specialty Pharmacy Times 2006-2019, 2 Clarke Drive Suite 100 Cranbury, NJ 08512 P:609-716-7777 F:609-716-9038, Gabapentin ≤900 mg/day → pregabalin 150mg/day, Gabapentin 901 mg/day to 1500 mg/day → pregabalin 225 mg/day, Gabapentin 1501 mg/day 2100 mg/day → pregabalin 300 mg/day, Gabapentin 2101 mg/day 2700 mg/day → pregabalin 450 mg/day, Gabapentin >2700 mg/day → pregabalin 600 mg/day, Gabapentin 900 mg/day → pregabalin 150 mg/day, Gabapentin 1800 mg/day → pregabalin 300 mg/day, Gabapentin 3600 mg/day → pregabalin 600 mg/day. Shared secondary neurochemical targets for pregabalin and gabapentin include: GAD; BCATc; GABA-T; GDH; NMDA receptors; EAAT3; and voltage-gated potassium channels. Higher bioavailability: The oral bioavailability of pregabalin (Lyrica) is high (~90%) regardless of dosing and/or whether administered with food – whereas the oral bioavailability of gabapentin (Neurontin) fluctuates between moderate (~60%) and low (~27%) depending on: dosing (bioavailability is inversely proportionate to dose) and food intake (high protein meals increase its bioavailability). If solely comparing the standard immediate-release versions of pregabalin and gabapentin, one might perceive pregabalin as advantageous over gabapentin on the basis of its longer duration of action. Migraine (prophylaxis). New York, NY: Park-Davis, Division of Pfizer; December 2013. Alcohol withdrawal. Cannabidiol (CBD) Side Effects & Adverse Reactions, L-Tyrosine Side Effects & Adverse Reactions (List), Armour Thyroid Side Effects & Adverse Reactions (List), Remeron (Mirtazapine) Withdrawal Symptoms + How Long They Last. 2016: The Cost-Effectiveness of Pregabalin Versus Gabapentin for Peripheral Neuropathic Pain (pNeP) and Postherpetic Neuralgia (PHN) in China. Corresponding Author: David J. Greenblatt, Tufts University School of … Nonetheless, from a clinical perspective, there’s no strong evidence to suggest that pregabalin is more efficacious than gabapentin in the management of neuropathic pain (despite FDA-approval of the former (pregabalin) and lack thereof for the latter (gabapentin)). Formatting options: Although gabapentin is available in fewer total dosing increments than pregabalin, gabapentin offers a greater number of formatting options than pregabalin. The American Journal of Pharmacy Benefits. However, in the 22 patients who received increased pregabalin dosages after the transition (due to insufficient symptom relief), visual analogue scale (VAS) pain scores significantly decreased. Data from this study support the idea that pregabalin might be more effective than gabapentin (even if average gabapentin dosages are more potent) for the treatment of postherpetic neuralgia. What’s more, pregabalin has been reported as 2-to-4-fold and 3-to-10-fold more potent than gabapentin as an analgesic and anticonvulsant, respectively. Researchers performed a base-case analysis (using intention-to-treat last observation carried forward method) and two sensitivity analyses (among completer and responder populations). In the event that an individual discontinues pregabalin (Lyrica) or gabapentin (Neurontin) treatment after a moderate- or long-term, the former user may experience an array of disconcerting physical and psychological withdrawal symptoms. Researchers believe that the primary neurochemical action (voltage-dependent calcium channel inhibition) of pregabalin and gabapentin accounts for a majority of their therapeutic effects in the management of medical conditions (e.g. Shorter duration of action: Though some individuals prefer pregabalin’s longer duration of action (8 to 14 hours) over gabapentin’s shorter duration of action (5 to 8 hours) – others prefer the opposite. In the 2 simulation trials, pregabalin was reported to be more effective than gabapentin, however, these were “simulations” conducted with questionnaire data by Pfizer Inc. employees – not legitimate head-to-head comparisons. Similar off-label uses for pregabalin and gabapentin is to be expected considering that the medications exhibit similar primary mechanisms of action involving modulation of α2δ subunit-containing voltage-dependent calcium channels (VDCC). 3. Multiple sclerosis-related pain and spasticity. Lyrica (pregabalin) and Neurontin (gabapentin) are both classified as “gabapentinoids” (i.e. There are also subtle differences in the incidence rates of side effects associated with pregabalin (Lyrica) and gabapentin (Neurontin). therapeutic responses) than gabapentin users. lol. Since only gabapentin is available in standard-release tablet format (and pregabalin is not), pregabalin users who wish to precisely adjust dosing will need to: (1) carefully empty powder from capsules (while avoiding spills) and (2) measure out specific quantities of powder for ingestion – this takes time, increases risk of dosing errors, and/or could be perceived as a hassle. For example, according to Manville and Abbott (2018), gabapentin is a potent activator of the voltage-gated potassium channels (VGPCs) KCNQ2/3; KCNQ3; and KCNQ5 – whereas pregabalin does not activate (at standard doses) or inhibits (at high doses) KCNQ2/3. Insomnia. The study is created by eHealthMe based on reports (from sources including the FDA) of 505,630 people who take Gabapentin and Pregabalin, and is updated regularly. 1. Anxiety disorders. Neuropathic pain is a result of damage to the nervous system itself that results in nerves sending out messages that are either incorrect or unhelpful. In comparison, users of pregabalin will be under its influence and prone to treatment-related side effects for a bulk of the day (8 to 14 hours) – which may be less preferable.
