How to treat a blister
Blisters usually result from friction on the hands or soles and can be painful but heal easily once the cause is removed. Follow the treatment steps below, which are based on NHS recommendations:
1. Wash your hands:
“Wash your hands before touching a burst blister.” 1
2. Observe hygiene:
Do not burst a blister yourself; it is likely that you will contaminate the wound. If it is already burst, “allow the fluid to drain before covering it with a plaster or dressing.” 1
3. Cover the wound:
“To protect your blister from becoming infected, a pharmacist can recommend a plaster or dressing to cover it while it heals.
A hydrocolloid dressing can help reduce pain and speed up healing.” 1
4. Manage pain:
Use an ice pack wrapped in a towel for up to 30 minutes to cool the wound.
When to seek medical advice
A common blister on your hand or foot can easily be treated at home. A visit to the doctor is necessary, however, if the blisters
- appear without any obvious reasons.
- appear in unusual places, e. g. eyelids, mouth or genitals.
- were caused by a burn, scald or an allergic reaction.
- become infected.
How to recognize an infected blister
If a blister becomes infected, the body's reactions to invading pathogens can be a warning signal. Pay attention to whether the wound
- become more painful,
- is warm to touch,
- looks red or swollen,
- leaks some blood-like liquid, pus or blood,
- has an unpleasant smell
If you notice an elevated body temperature (above 99.5 °F) or see any of the signs mentioned, please contact your health care practitioner! 2
