How to deal with severe rash caused by dacomitinib/dacomitinib (Dozerun)

Dacomitinib/Dacomitinib (Dacomitinib) acts on the EGFR signaling pathway, and skin-related reactions are common, among which rash is one of the more prominent problems. When the rash is severe, patients with non-small cell lung cancer not only feel uncomfortable, but may also affect subsequent treatment plans, so correct treatment is particularly critical. Generally speaking, rashes often appear in the early stages of treatment, usually in areas rich in sebaceous glands such as the face, scalp, chest and back. If erythema, papules, or itching worsens, it is recommended that patients communicate with their doctor as soon as possible instead of using irritating topical medications on their own.

Emphasis"Early intervention" is the key to controlling rash. The first step is to make sure your skin barrier is not compromised by using a gentle, fragrance-free moisturizer to reduce dryness and irritation. Avoid bathing in hot water, avoid using alcohol-based or cleansing products with strong degreasing capabilities, and reduce sun exposure, as ultraviolet rays can aggravate skin reactions. When doing outdoor activities, you can use physical sunscreens, such as products containing zinc oxide or titanium dioxide, which are less sensitive and more suitable for use during targeted medicine.

If the rash worsens to obvious redness and swelling or even oozing, doctors will usually instruct you to use low- to medium-strength topical ointments and, if necessary, short-term oral antipruritic or anti-inflammatory drugs to relieve symptoms. In some cases, patients may need to briefly stop taking the drug to restore skin condition, but such decisions should be evaluated by a doctor, and it is not recommended to interrupt the treatment course without authorization. If the rash is accompanied by pain, ulceration and other symptoms around the nails, corresponding local care should also be taken to keep the wound dry and avoid infection.

Life management is also important, such as choosing soft clothing, reducing friction, and avoiding scratching to avoid secondary infections. For patients with severe scalp rash, you can use mild shampoo products to avoid irritating ingredients. Most rashes can be effectively controlled through these methods without affecting long-term treatment.
