A blister is a raised area of skin filled with clear fluid. To remove a blister effectively and safely, follow these steps:
Treating a Blister: A Step-by-Step Guide
-
Leave it alone (if small and intact): Small, intact blisters often heal best on their own. Keep the area clean and dry, and cover it with a bandage to protect it from friction. Mayo Clinic recommends this approach for many blisters.
-
Drain a large or painful blister: If the blister is large, painful, or in a location prone to rubbing (like on your foot), draining it might help relieve discomfort. This is best done by a healthcare professional, but if you choose to do it yourself:
- Sterilize a needle: Clean a sharp needle with an antiseptic wipe or rubbing alcohol. Healthline and other sources emphasize the importance of sterilization.
- Prick the blister: Carefully prick the blister in several spots near the edge, allowing the fluid to drain. Do not remove the overlying skin.
- Apply ointment and bandage: Apply an antibiotic ointment (like Neosporin) or petroleum jelly to the area and cover it loosely with a nonstick bandage or gauze pad. WebMD recommends this approach for healing.
-
Keep the area clean: Clean the area gently with soap and water, and pat it dry. Avoid scrubbing. NHS recommends keeping the area as clean as possible.
-
Protect the blister: Cover the blister with a soft plaster or padded dressing to protect it from further irritation. This prevents further injury and promotes healing. Better Health Channel and other sources highlight the importance of this step.
Important Note: Never forcefully peel off the skin covering the blister. This can increase the risk of infection and delay healing.
Types of Blisters and Additional Considerations
-
Blood blisters: These blisters contain blood instead of clear fluid. Treatment is similar to other blisters; however, they might take longer to heal. Cleveland Clinic provides information on blood blisters.
-
Large or infected blisters: If a blister is very large, extremely painful, shows signs of infection (increased pain, redness, swelling, pus), or doesn't improve after a few days, consult a doctor or other healthcare professional.
