Other movement disorders reported with gabapentin include myoclonus, ataxia, and choreoathetosis. Gabapentin has been used to treat dystonias with variable results. Conclusions: Although gabapentin is widely used and well tolerated, it can cause dystonic reactions, which are reversible after drug withdrawal. Many widely used medications may cause or exacerbate a variety of arrhythmias. Numerous antiarrhythmic agents, antimicrobial drugs, psychotropic medications, and methadone, as well as a growing list of drugs from other therapeutic classes (neurological drugs, anticancer agents, and many others), can prolong the QT interval and provoke torsades de pointes. Perhaps less familiar to clinicians is Note: This document provides detailed information about Neurontin Side Effects associated with gabapentin. Some dosage forms listed on this page may not apply specifically to the brand name Neurontin. Applies to gabapentin: oral capsule, oral solution, oral suspension, oral tablet, oral tablet extended release 24 hr. Serious side effects of Gabapentin can affect your heart rate in a few different ways. In a double-blind, observational study, patients undergoing elective surgery were administered different doses of gabapentin. The study found that 400mg of gabapentin resulted in a higher heart rate and blood pressure, whereas 800mg of gabapentin resulted in a lowered heart rate. Unilateral microinjection of gabapentin into the NTS produced prominent dose-related depressor and bradycardic effects in SHR rats. The cardiovascular effects of gabapentin were attenuated by the prior administration of the NOS inhibitor, L-NAME. Many of these can cause a fast heartbeat, including inhaled corticosteroids, albuterol, inhaled long-acting beta-2 agonists, leukotriene modifiers, and oral methylxanthines. Antibiotics Some side effects of gabapentin may occur that usually do not need medical attention. These side effects may go away during treatment as your body adjusts to the medicine. Also, your health care professional may be able to tell you about ways to prevent or reduce some of these side effects. Results: Unilateral microinjection of gabapentin into the NTS produced prominent dose-related depressor and bradycardic effects in SHR rats. The cardiovascular effects of gabapentin were attenuated by the prior administration of the NOS inhibitor, L-NAME. Gabapentin and pregabalin can cause fluid retention, which is hypothesized to be associated with cardiovascular diseases. However, whether long-term use of gabapentin and pregabalin is associated with adverse cardiovascular diseases remains unknown. It has been recently demonstrated that gabapentin can induce vasodepression and bradycardia acting through the nitric oxide pathway [80]. Indeed, gabapentin is known to attenuate the hypertensive Bradycardia is reported as a side effect among people who take Gabapentin (gabapentin), especially for people who are male, 60+ old, have been taking the drug for < 1 month also take Aspirin, and have Secondary progressive multiple sclerosis. In sympathectomized SHR-gabapentin decreased epinephrine but not norepinephrine levels, whereas gabapentin-induced changes of plasma catecholamines were not significant in sympathectomized WKY rats (Table). These results indicate that the reduction of plasma epinephrine level may be the cause of observed gabapentin-induced bradycardia in SHR. More rarely, gabapentin can cause fluid buildup (edema), weight gain, and vision problems. It can also cause diarrhea. More serious (but rare) side effects include suicidal thoughts or behavior, and mood changes in children. Gabapentin and pregabalin are commonly prescribed medications to treat pain in patients with diabetic neuropathy. Gabapentin and pregabalin can cause fluid retention, which is hypothesized to be associated with cardiovascular diseases. Gabantin or gabapentin: There were some side effects associated with gabapentin such as hypotension and bradycardia and considered rare cases (less than 0.1%). Also , there were post-marketing and case reports of bradycardia (slow heart rate) Sensitivity analyses. In the main analyses, we used propensity score matching for other potential indications for gabapentinoids. To evaluate the soundness of the results of main analyses, we conducted sensitivity analyses for the subpopulation without any diagnosis of other potential indications, including diabetic neuropathy, seizure, postherpetic neuralgia, neuropathic pain, or restless leg Purpose of Review The objective of this manuscript is to describe the cardiovascular effects of the gabapentinoids gabapentin and pregabalin. Recent Findings The most frequent adverse effects of gabapentin and pregabalin affect the central nervous system, such as somnolence and fatigue. Additionally, pregabalin, and a much lesser extent, gabapentin, may adversely affect the cardiovascular A decreased peripheral sympathetic nerve transmission and suppressed central sympathetic nerve outflow can explain GBP-induced hypotension and bradycardia, however this not likely the cause of GBP-evoked new onset congestive heart failure [10,11], decompensation of pre-existing heart failure [21,22,23], or an increase in the risk of heart The evidence suggests that gabapentin can lower heart rate, particularly in acute settings such as anesthesia induction and in hypertensive models. Chronic administration also appears to suppress cardiovascular function, leading to bradycardia. In rare cases, it can lead to development of new onset congestive heart failure (CHF) or decompensation of pre-existing CHF. We present a case of gabapentin induced CHF with rapid resolution after discontinuing the medication.
