Cyclosporin-Induced Gastrointestinal Side Effects

Gastrointestinal Adverse Effects

Nausea and vomiting occur in up to 10% of patients taking cyclosporin, according to the American Thoracic Society, with diarrhea occurring in up to 8% of patients 1
Stomach discomfort and abdominal pain are also associated with cyclosporin use, as reported by the American College of Chest Physicians 1

Higher doses of cyclosporin are associated with increased risk of severe gastrointestinal effects, as noted by the American College of Chest Physicians 2
Concomitant medications that affect cyclosporin metabolism can increase blood levels and associated toxicity, according to the British Thoracic Society 3

Therapeutic drug monitoring is essential to maintain appropriate trough levels, typically 150-250 ng/mL for most indications, as recommended by the American Gastroenterological Association 4 and the American College of Chest Physicians 2
Dose adjustments may help reduce gastrointestinal side effects while maintaining efficacy, as suggested by the European Society for Clinical Nutrition and Metabolism 4 and the British Society of Gastroenterology 5
Regular laboratory monitoring, including CBC, renal function, liver function, and electrolytes, is necessary, as recommended by the American College of Chest Physicians 1 and the American Thoracic Society 6

In patients with inflammatory bowel disease treated with cyclosporin, minor adverse events including nausea and vomiting occurred frequently but usually responded to dose adjustment, as reported by the European Crohn’s and Colitis Organisation 5
Transplant recipients experiencing gastrointestinal side effects can typically be managed with appropriate monitoring, according to the International Society for Heart and Lung Transplantation 6 and the American College of Chest Physicians 1
Patients with dermatological conditions should be informed about potential gastrointestinal side effects before starting therapy, as recommended by the British Association of Dermatologists 7
