Bullae are large, fluid-filled blisters that form on the skin. They are bigger than 0.5 cm and may appear suddenly. Bullae can be painful and are often caused by skin injuries, infections, or immune system problems. Early diagnosis and treatment can ease discomfort and protect your skin.

Bullae can vary in size and severity.
Spotting the symptoms early can help with faster and better treatment.
Common Symptoms of Bullae:

Severe Symptoms of Bullae:

Get Second OpinionHow is Bullae Diagnosed?
The diagnosis of bullous disease is based on clinical observation and tests to determine the underlying disease.
Common Diagnostic Methods:
- Skin Check: Looking at size, location, and appearance
- Medical History: Asking about injuries, allergies, or past infections
- Skin Biopsy: Testing a small piece of skin to check for disease
- Blood Tests: Looking for infection or immune problems
At Medicover, we use advanced tools and lab tests to find the cause quickly and start the right treatment.
What are the Treatment Options for Bullae?
Treatment for bullae depends on the cause and how severe the blisters are.
The main goals are to relieve discomfort, prevent infection, and help the skin heal properly.
Medical Treatments:
- Topical creams: Antiseptic or healing ointments for mild blisters
- Oral medications:
- Antibiotics if there's an infection
- Steroids or immune-suppressing drugs for autoimmune causes
- Pain relief: Over-the-counter options like ibuprofen or paracetamol
Supportive Care:
- Keep the area clean and covered with sterile dressings
- Avoid pressure, friction, or heat on affected skin
- Rest well and stay hydrated to support healing
Hospitalisation:
In serious cases, such as drug reactions (like Stevens-Johnson Syndrome), you may need hospital care. This includes fluid replacement, pain management, and specialist care.
