Chickenpox and the elderly: what to know

Chickenpox, also called varicella, causes an itchy blistering rash and fever. In later adulthood, the illness may place more strain on the body, particularly when breathing becomes difficult or another health condition is present. A new blistering rash can resemble shingles, but shingles usually follows a localised pattern rather than appearing as a widespread new rash. A clinician can assess the pattern, timing, medicines and medical history.

Arrange a GP Consultation promptly and mention the person’s age, when the fever or rash began, and any immune-suppressing medicine. Avoid close contact with pregnant people, newborn babies and anyone with reduced immunity until a clinician explains when this is safe. Keep the skin clean, use loose clothing, drink regularly and avoid scratching. Antiviral Treatment may be considered, especially when started early; do not start leftover medicine without advice. An oral antihistamine may help itching when a clinician or pharmacist says it is suitable.

Seek urgent medical help for trouble breathing, chest pain, confusion, severe drowsiness, dehydration, repeated vomiting, a rapidly worsening rash, or severe headache with neck stiffness. Also seek prompt review if blisters become very painful, hot, swollen or draining, as this may suggest a skin infection. Fever that persists or returns deserves assessment rather than being judged by age alone.

Ask whether the rash is chickenpox or shingles, whether antiviral treatment is appropriate, which medicines are safe for fever and itching, and how long to avoid vulnerable contacts. Ask what breathing or skin changes should trigger urgent review and whether vaccination should be discussed after recovery.
