How is bullous pemphigoid different in older adults?

Bullous pemphigoid happens when the immune system targets structures that anchor the outer skin layer. The resulting blisters are often firm rather than easily burst, and they may arise on the abdomen, limbs, or skin folds. In an older person, itching may disturb sleep and scratching can break the skin, allowing infection to develop. Some people have a non-blistering phase with itch, redness, or raised patches. Other causes of blisters, medication reactions, eczema, and infections can look similar, so examination is needed; a dermatologist may take a small skin sample or arrange blood tests.

Arrange prompt medical assessment for new unexplained blisters, especially when they are spreading or interfering with eating, sleeping, or walking. Keep blisters clean and intact, use a gentle cleanser, and avoid adhesive dressings on fragile skin. Do not start or stop a medicine without advice, but bring every prescription, non-prescription product, and supplement to the appointment. Treatment may include anti-inflammatory medicine applied to the skin or taken by mouth, with a plan to reduce inflammation safely. A clinician may also discuss infection prevention, dressings, hydration, and help from a carer if movement or eyesight makes wound care difficult.

Seek urgent help if blisters involve the eyes, mouth, or throat; if there is trouble swallowing or breathing; or if the person becomes confused, faint, unusually weak, or unable to drink. Fever, rapidly increasing redness, warmth, swelling, pus, worsening pain, or a foul smell from an open area can signal infection. An older adult who is unsteady, falling, or unable to manage meals or medicines also needs prompt review.

Ask what confirms the diagnosis, which medicines could worsen drowsiness or falls, how to protect fragile skin, and who should change dressings. Clarify the treatment schedule, what to do after a missed dose, and which symptoms should trigger same-day advice. If a family member helps, ask for written instructions that everyone can follow.
