Voriconazole is an important antifungal, but it can make your skin much more sensitive to sunlight. Some people develop mild rashes, while others can get severe sunburn even after only a few minutes outdoors.
🌞 Protect your skin every day
-
High-factor sunscreen (SPF 50+) on all exposed skin, even in winter or cloudy weather.
-
Lip balm with SPF for lips, which are often affected.
-
Protective clothing: hats, long sleeves, UV-blocking fabrics if possible.
-
Avoid peak sun (11am–3pm) and try to stay in shade when outdoors.
👀 Watch your skin closely
-
Report any new rashes, blisters, lumps, or patches to your specialist team.
-
Regular skin checks may be offered if you are on long-term voriconazole.
💊 Medication review
-
If severe reactions develop, your doctors may:
-
Adjust the dose
-
Switch you to another antifungal (e.g. posaconazole, isavuconazole)
-
Add specialist dermatology follow-up
-
🚨 When to act fast
Seek medical advice urgently if you develop:
-
Blistering burns after short sun exposure
-
Painful or rapidly changing skin lesions
-
Any signs of infection in damaged skin
💙 Key message for patients: Sun sensitivity on voriconazole is common enough that everyone should take precautions. Don’t wait until your skin is badly affected — protect daily, and tell your team about any changes.
