Treatment for blisters includes:

• Protect the blister from further injury.
• Clean the blister gently with soap and water.
• Apply a protective bandage over the blister.
• Do not puncture a blister. This increases the risk of infection.
• Care for a ruptured blister:
• Clean the skin gently with soap and water.
• Apply antibiotic ointment.
• Apply a protective bandage over the blister.

A tetanus shot may be necessary if your blister has ruptured.

Tetanus Considerations
A tetanus shot is necessary right away if you have not had three tetanus shots in the past.

If you have received three tetanus shots in the past, you need a tetanus shot within three days for an open blister that occurred outdoors.
