Spider Bite or Scorpion Sting: Care Instructions
Overview
Spider bites and scorpion stings often cause minor swelling, redness, pain, and itching. These mild symptoms are common and may last from a few hours to a few days. Some people have more severe reactions.
Home treatment is often all that you need to relieve symptoms.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse advice line (811 in most provinces and territories) if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
How can you care for yourself at home?
- Put ice or a cold pack on the area for 10 to 20 minutes at a time. Put a thin cloth between the ice and your skin.
- Try an over-the-counter medicine for itching, redness, swelling, and pain. Be safe with medicines. Read and follow all instructions on the label.
- Take an over-the-counter antihistamine to help calm the itching or swelling.
- Put a hydrocortisone 1% cream or calamine lotion on the skin.
- Don't scratch or rub the skin around the area.
When should you call for help?
Call 911 anytime you think you may need emergency care. For example, call if:
