Blister Medicine

Blisters are a common skin complaint, often caused by friction, burns, or certain medical conditions. They form as small pockets of fluid under the skin, designed to protect the damaged area and aid healing.

Effective Blister Treatment and Prevention

Proper care of a blister is crucial to prevent infection and promote healing. Here are some key steps and products that can help:

  • Protect the Blister: The most important step is to protect the blister from further friction or pressure. Specialised blister plasters from brands like Compeed are designed to cushion the area, absorb fluid, and provide an optimal healing environment. Look for options with hydrocolloid technology for best results.
  • Cleanse & Disinfect: If a blister has broken, or if you choose to carefully drain a large, painful one (only if necessary and with sterilised equipment), it's vital to keep the area clean to prevent infection. Use a gentle antiseptic solution like Safe & Sound Cleansing Antiseptic Spray or Elastoplast Wound Cleaning Spray. Follow up with an antiseptic cream from trusted brands like Savlon, Acriflex, or Germolene.
  • Reduce Friction: For ongoing prevention, especially for foot blisters, consider using padding or protective solutions from Profoot to minimise rubbing, or ensure your footwear fits correctly. Our Foot Care section has many preventative products.

Always keep an eye on the blister for signs of infection, such as increased redness, swelling, pus, or fever. If you're unsure or concerned, consult a healthcare professional.

Blisters FAQs

What is a blister?

A blister is a small pocket of fluid (usually clear serum, but can be blood or pus) that forms under the top layer of skin. They are typically round or oval and can vary in size. Blisters form as a protective mechanism by the body to cushion and heal damaged skin underneath, often caused by friction, burns, or reactions to certain substances.

Should I pop a blister?

Generally, it's best not to pop a blister. The skin over the blister acts as a natural barrier against infection. If you pop it, you break this barrier, increasing the risk of bacteria entering and causing an infection. It's usually better to leave the blister intact and let it heal naturally. If a blister is very large, painful, or in an awkward place, and you feel you must drain it, do so carefully using a sterilised needle and then keep the area clean and covered.

How can I prevent blisters?

Preventing blisters often involves reducing friction. For feet, ensure you wear well-fitting shoes and socks, and consider moisture-wicking materials. You can also use protective pads, tapes, or creams in areas prone to rubbing. For hands, wear gloves when doing activities that cause friction. For burns, immediate cooling can help reduce blister formation. Keeping skin moisturised can also help maintain its integrity.

When should I see a doctor or pharmacist for a blister?

You should see a doctor or pharmacist if a blister becomes very painful, swollen, red, or starts producing pus, as these are signs of infection. Also seek advice if you have a fever or red streaks extending from the blister. People with certain conditions, like diabetes or poor circulation, should seek professional medical advice for any blister, as they are at higher risk of complications.
