People taking voriconazole need to be very cautious in the sun because this antifungal can cause photosensitivity reactions—meaning the skin becomes more sensitive to sunlight, even through glass or on cloudy days. This can lead to severe sunburn, skin blistering, and long-term damage, including premalignant and malignant skin changes (like squamous cell carcinoma), especially with prolonged use.

Here’s what people on voriconazole should do to protect themselves:

☀️ Sun Safety Tips for Voriconazole Users

  1. Avoid direct and reflected sunlight:

    • Try to stay indoors between 10 a.m. and 4 p.m., when UV rays are strongest.

    • Choose shaded routes or walk on the shady side of the street.

    • Avoid indirect or reflected sunlight (e.g. off windows, water, sand, snow)

  2. Wear protective clothing:

    • Long-sleeved tops, trousers, and wide-brimmed hats are essential.

    • Consider UV-protective clothing (many brands offer this specifically).

    • Use UV-protective sunglasses to shield your eyes.

  3. Use high-factor sunscreen:

    • Broad-spectrum SPF 50+ sunscreen is best.

    • Apply generously to all exposed skin, including hands, ears, and neck.

    • Reapply every 2 hours, and after sweating or washing.

  4. Avoid sunbeds and tanning lamps:

    • Artificial UV exposure can also cause damage.

  5. Check windows:

    • UV-A rays can penetrate glass, so use UV-filtering films on car and home windows if needed.

  6. Regular skin checks:

    • Long-term voriconazole use has been linked to skin cancer, especially in immunocompromised individuals.

    • See a dermatologist regularly, and report any new or changing skin lesions.

⚠️ Signs of Photosensitivity to Watch For:

  • Red, itchy, or painful rash in sun-exposed areas

  • Skin blistering or peeling

  • New moles or spots, or changes to existing ones

If you’re on long-term voriconazole and sun exposure is unavoidable, it might be worth discussing alternative antifungal treatments with your doctor, especially if skin damage begins to occur.

Here’s a mix of recommended sunscreens and UV-protective gear that people on voriconazole (especially those with prolonged use or immunosuppression) often find effective. These are high-protection, broad-spectrum, and suitable for sensitive or compromised skin.
