The most common side effects are acne, erythema , and burning and stinging of the skin.
Local irritation, erythema , ulceration, and tenderness were common reactions.
Early application of topical steroids is useful to limit erythema and pruritus.
For people with light skin, any erythema should be a signal for intervention and monitoring.
The only adverse effects of therapy were transient skin erythema and local hair loss in three irradiated patients.
At 24 hours after irradiation, sites were visually assessed to determine the minimal erythemal dose, i.e. the lowest dose at which erythema was perceptible.
In the past, the term minimum erythemal dose was often used as a measure of the cumulative UVR (ultraviolet radiation) exposure required to induce erythema or sunburn in people.
A depletion of the ozone column by 25% could increase the erythemal exposure of field scientists or indigenous arctic people by approximately 40% during the spring.
Thrush and erythematous candidiasis are common in patients with immune defects and are often an early manifestation of the immunodeficiency.
The disease begins as an erythematous papule at the site of the sandfly bite on exposed parts of the body.
