Vesicant chemotherapy drugs are characterized by...

• A. Vesicant chemotherapy drugs cause severe local tissue breakdown and necrosis if infiltrated into skin
• B. Vesicants cause only mild irritation
• C. Vesicants have no tissue damage
• D. Vesicants cause systemic effects only

Answer: (A)

Vesicant chemotherapy drugs are defined by their ability to cause serious tissue injury when they escape from the vein into surrounding tissue. If a vesicant leaks into the skin, it damages cells and blood vessels, leading to rapid tissue necrosis, ulceration, and potential loss of tissue. That local, destructive effect is the key feature, which is why the statement describing severe local tissue breakdown and necrosis upon infiltration is the best fit. While these drugs can also have systemic toxicity, the defining concern with vesicants is the potential for severe local damage at the infusion site. The other options describe scenarios that don’t capture this important local tissue-damage risk.
