What should you know about cellulitis after IV removal?

Mild soreness or a small bruise can follow IV removal. Cellulitis is more concerning when redness, warmth, swelling, tenderness, or pain increases or spreads beyond the puncture site. Fluid leaking under the skin, a firm tender vein, or a raised area can have other explanations, so examination helps distinguish them. Keep the site visible and note whether the redness is changing. Tell the clinician what was infused and when the IV was removed, especially if the area has become worse since leaving hospital.

Contact the healthcare team that placed the IV or arrange prompt medical assessment if the site is becoming hotter, redder, more swollen, or more painful. Keep the skin clean and dry, avoid rubbing or piercing the area, and do not use leftover antibiotics. Follow any dressing instructions you were given. Mention fever, drainage, red streaks, diabetes, immune conditions, or medicines that affect healing. A clinician may decide whether antibiotics or another treatment is appropriate.

Seek urgent care for rapidly spreading redness, severe pain, pus, marked swelling of the arm or hand, fever, chills, faintness, confusion, fast breathing, or sudden severe illness. These features can indicate a spreading infection or sepsis. Breathing trouble, facial swelling, or widespread hives after an infusion is an emergency and may represent an allergic reaction rather than cellulitis.

Ask whether the site looks like cellulitis, vein inflammation, bruising, or another problem; whether a sample or scan is needed; how to dress it; and when it should be checked again. Ask which changes should send you straight to urgent care.
