Mirtazapine Use in Post-Bariatric Surgery Patients

Safety and Efficacy

Dumping syndrome, which includes symptoms like nausea, vomiting, and hypoglycemia, affects approximately 40% of patients after Roux-en-Y gastric bypass or sleeve gastrectomy, and symptoms can persist for many years after surgery 1, 2
Mirtazapine's appetite-stimulating effects may be beneficial for patients who experience excessive weight loss after bariatric surgery, with some patients losing up to 30% of their preoperative weight due to food avoidance 1

Regular monitoring of weight is important when using mirtazapine in post-bariatric surgery patients, as its appetite-stimulating effects should be balanced against the weight loss goals of bariatric surgery 1, 3
Patients should be monitored for symptoms of dumping syndrome, which can include both early symptoms and late symptoms 1
If patients experience hypoglycemic symptoms while taking mirtazapine, dietary modifications should be implemented first, followed by pharmacological interventions if necessary 4

Dietary modifications should be the first-line approach for patients experiencing significant dumping syndrome symptoms, followed by pharmacological interventions if necessary 1, 4
