Drug-induced hyponatremia caused by renal water retention is mainly due to syndrome of inappropriate antidiuresis (SIAD). SIAD can be grouped into syndrome of inappropriate antidiuretic hormone secretion (SIADH) and nephrogenic syndrome of inappropriate antidiuresis (NSIAD). The former is characterized by uncontrolled hypersecretion of arginine vasopressin (AVP), and the latter is produced by Gabapentin and pregabalin are less likely to cause hyponatremia, although a few isolated cases have been reported. The association between CBZ, OXC, and hyponatremia dates back to the 1970s and 1980s, with varying reported incidences across different studies [ 17 , 18 ]. Check with your doctor immediately if any of the following side effects occur while taking gabapentin: More common in children. 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. Hyponatremia 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 Ondansetron, and have Stress and anxiety. This article summarizes the causes, mechanisms, and clinical manifestations of hyponatremia induced by various drugs, including gabapentin. It also discusses the diagnosis, treatment, and prevention of this condition, as well as the role of uric acid and vasopressin in its pathogenesis. The higher rate of hyponatremia under ESL in our study probably reflects the impact of higher doses on the probability of hyponatremia which has been reported for CBZ and OXC (O’Hare et al., 1980; Lahr, 1985; Nielsen et al., 1988; Yassa et al., 1988; Berghuis et al., 2017) and is highly plausible for ESL also although the relatively small ESL The most frequent electrolyte disorder in hospitalized patients is hyponatremia [1]. The clinical spectrum in hyponatremia ranges from mild, non-specific symptoms such as fatigue, headache, and gait instability to life-threatening symptoms such as seizures, coma and ultimately death, secondary to brain oedema [2,3]. Pharmaceutical drugs, e.g., thiazide diuretics, antidepressants and Carbamazepine and oxcarbazepine are the anticonvulsants most commonly reported to be associated with hyponatremia in patients with epilepsy, although other anticonvulsants, such as eslicarbazepine, sodium valproate, lamotrigine, levetiracetam, and gabapentin, have also been reported to cause hyponatremia . Expert opinion: Carbamazepine and oxcarbazepine are the most common AEDs which induce hyponatremia in patients with epilepsy. Recently, other AEDs, such as eslicarbazepine, sodium valproate, lamotrigine, levetiracetam and gabapentin have also been reported to cause hyponatremia. However, these reports were based on only 1–4 patients with severe hyponatremia, so the actual incidence of this problem is unknown. According to a population-based case-control study, use of CBZ, phenytoin (PHT), VPA, LTG, LEV, or gabapentin increases the risk of hospitalization for hyponatremia [17]. However, this study was based on a The corresponding association for phenytoin and valproate was moderate. The risk for hyponatremia was lower during ongoing treatment. Lamotrigine and gabapentin had the lowest risk both during initiation and ongoing treatment and may be advantageous in patients at risk of developing hyponatremia. Studies have shown a potential association between gabapentin use and an increased risk of developing hyponatremia. While the exact mechanism is not fully understood, it is believed that gabapentin may affect the regulation of sodium levels in the body. Our study showed a mild increase in hospitalization due to hyponatremia within 90 days of the first prescription but a non–significant decrease in risk during chronic use. Thus, gabapentin seems to carry a very low over-all risk of inducing hyponatremia. Nicotine patch therapy can induce hyponatremia. The proposed mechanism is a possible syndrome of inappropriate antidiuretic hormone (SIADH) induced by this drug. A Review of Drug-Induced Hyponatremia George Liamis, MD, Haralampos Milionis, MD, and Moses Elisaf, MD Hyponatremia (defined as a serum sodium level 134 mmol/L) is the most common electrolyte abnormality in hospitalized patients. Certain drugs (eg, diuretics, antidepressants, and antiepileptics) Carbamazepine and oxcarbazepine are the most common antiepileptic drugs (AEDs) associated with hyponatremia. 1,21 Recently, other AEDs, such as eslicarbazepine, sodium valproate, lamotrigine, levetiracetam and gabapentin, have also been reported to induce hyponatremia. 43 In fact, older adults on valproic acid, phenytoin or topiramate have a hig This case can help clinicians diagnose and treat new-onset hyponatremia in patients who recently initiated pregabalin therapy. Keywords: Drug associated syndrome of inappropriate antidiuretic hormone secretion, Hyponatremia, Pregabalin. Introduction. Hyponatremia is the most frequent electrolyte disturbance among hospitalized patients1,2). When taking gabapentin, there are steps you can take to lower the risk of hyponatremia. Eating a balanced diet with enough sodium is key. Eating foods high in sodium is important for keeping electrolytes balanced. Background.
