Itching during dengue

Dengue can cause a changing skin rash as the illness develops, and the rash may itch as it fades or as the skin becomes sensitive. Itching does not by itself show whether dengue is mild or becoming more serious. A person with a suspected or confirmed infection needs attention to the overall illness, not only the skin.

Other itchy rashes, including hives, contact dermatitis, eczema, or a skin infection, can happen at the same time or resemble part of a dengue rash. Tell the treating clinician when the fever, rash, and itch began, and mention any medicines taken.

Rest, drink fluids as advised by your clinician, and keep the skin cool. Wear loose clothing and use a cool damp cloth for short periods. Keep nails short and avoid scratching, which can damage the skin and allow infection. Use only medicines recommended by a healthcare professional, because some pain medicines can increase bleeding risk during dengue.

Do not start an anti-inflammatory medicine, aspirin, antibiotic, steroid, or unfamiliar anti-itch product without medical advice. A clinician or pharmacist can choose a safe option based on your symptoms, hydration, age, pregnancy status, and other medicines.

Seek urgent medical help for bleeding from the nose or gums, vomiting blood, black stools, severe or persistent abdominal pain, repeated vomiting, unusual sleepiness, confusion, faintness, difficulty breathing, or inability to drink. Very little urine, cold clammy skin, or sudden worsening after the fever changes also needs urgent assessment.

Contact your treating clinician promptly if the rash becomes painful, blistered, infected-looking, or rapidly changes. Do not wait for the itch to settle before seeking help for warning signs. Keep follow-up appointments even when the skin seems better.

Is my rash consistent with dengue or another condition? Which pain and itch medicines are safe for me? How should I monitor fluids, urine, bleeding, and changes after the fever?
