Should you take diphenhydramine HCL or Zyrtec for wasp sting?

For a wasp sting, diphenhydramine HCL (Benadryl) may be more effective due to its sedative antihistamine properties, which can help alleviate itching and swelling. Zyrtec (cetirizine) is also an antihistamine but is less sedating and may not provide immediate relief for acute allergic reactions. It's essential to consider the severity of the sting and any history of allergic reactions. If symptoms are severe or persist, consult a healthcare professional.
