Common, Mild Side Effects: What's Expected
Most people tolerate IV therapy without issue. Some experience minor arm bruising or soreness around the catheter insertion site; this resolves within days. A small percentage report a brief sensation of coolness in the vein during infusion, a slight metallic or saline taste, mild dizziness (especially if standing quickly), or slight nausea (usually from hydration expansion in the stomach). These are short-lived and not dangerous. Drinking water before and after infusion reduces nausea risk.
