What is an effective treatment to stop swelling from a bee sting?
It only takes a few seconds for the venom from the stinger to enter the body, as Mayo Clinic states. For this reason, removing the stinger quickly, using fingers or tweezers, is essential to prevent a reaction. The next step is to wash the area with soap and water and apply a cold compress to reduce itching and swelling. Medicated treatments are also available in the form of creams or oral medicines. Calamine lotion is a useful topical medication that helps relieve itching. Diphenhydramine and chlorpheniramine are oral antihistamines that help reduce itching and swelling. Scratching the area of the sting can significantly worsen the pain and swelling.
