how long does it take for poison ivy to go away

Most cases of poison ivy rash go away on their own within 1 to 3 weeks. After about a week, the blisters typically start to dry up and the rash begins to fade. Mild cases might clear up in a week, but more severe or sensitive cases can take up to three weeks or longer. The rash usually appears within 12 to 48 hours after exposure to the plant. Keeping the rash clean, avoiding scratching, and using treatments like anti-itch creams, calamine lotion, or antihistamines can help relieve symptoms and potentially speed healing. If the rash lasts more than three weeks, spreads significantly, or causes severe symptoms, medical advice should be sought.
