What should I do if my skin is allergic to touching a spider web?

Skin allergy caused by contact with a spider web can generally be managed by immediately cleaning the affected area, applying cold compresses to relieve discomfort, using topical anti-allergy ointments, taking oral antihistamines, and avoiding scratching or irritation. Specific measures are as follows:

1. Clean the contact area immediately: Gently rinse the allergic skin with lukewarm water to remove residual components of the spider web as well as any attached dust or secretions. Avoid using soap or harsh cleansers that may worsen skin irritation. After washing, gently pat the area dry with a clean towel.

2. Apply cold compress to relieve discomfort: If the affected area becomes red, swollen, itchy, or feels hot, wrap an ice pack or a chilled damp towel in a clean cloth and apply it to the area for several minutes at a time. This helps constrict capillaries, reduce inflammatory responses, and alleviate symptoms such as swelling and itching.

3. Use topical anti-allergy ointments: When mild erythema or papules appear on the skin, apply a topical anti-allergic ointment—such as mometasone furoate gel or hydrocortisone butyrate cream—uniformly over the affected area to suppress local inflammation and relieve discomfort caused by the allergic reaction. Be sure to follow usage instructions and avoid prolonged application.

4. Take oral antihistamine medications: If the allergic reaction covers a large area, is accompanied by severe itching or mild skin swelling, consider taking oral antihistamines such as loratadine tablets or cetirizine hydrochloride tablets. These help control systemic allergic reactions quickly and reduce itching. Use only as directed by a physician or according to the medication instructions.

5. Avoid scratching and irritation: Resist the urge to scratch itchy areas, as scratching may break the skin, increase the risk of infection, and potentially worsen inflammation. Instead, try lightly tapping the area or distracting yourself to manage the itch. Keeping the skin intact promotes healing.

During the allergic episode, maintain clean and dry skin, wear loose, breathable clothing made of pure cotton, and minimize friction on the affected area. If symptoms do not improve after treatment, or if there is oozing from the skin, fever, or other concerning signs, seek medical attention promptly.
