If it is spring, patients prone to skin allergies should consider that it might be related to the inhalation of spring pollen, dust, and dust mites. It is also possible to consider that the revival of all things in spring and the increase in insects can lead to allergic reactions.

For patients who are prone to allergies in spring, it is advisable to visit a hospital to complete an allergen test to identify the cause of the allergies and avoid or eliminate them. If possible, desensitization treatments can also be considered.

For those who have already developed allergies accompanied by itching, oral antihistamines such as ebastine tablets and loratadine tablets can be taken for anti-allergy and anti-itch treatment. Topical external treatments like Liugan stone wash can also be used for anti-inflammatory and anti-itch treatment.

Is skin allergy contagious?

Skin allergies are not contagious. When skin allergies occur, it is essential to identify the allergen and determine the cause. Skin allergies often manifest as dermatitis, eczema, urticaria, and other allergic diseases, and can also present as diseases such as angioneurotic edema. Common symptoms include itching, papules, swelling, and rash patches, but there is no need to worry too much as they are not contagious.

Can people with skin allergies eat peanuts?

If you have skin allergies, be a little cautious with peanuts. If you have never been allergic to peanuts, eating them while having a skin allergy should not be a problem. Peanuts have high nutritional value and can be compared to animal foods such as eggs, milk, and meat, earning them the nickname "longevity fruit." Traditional Chinese medicine says that peanuts can strengthen the spleen and stomach and moisten the lungs to reduce phlegm. Clinically, we still see patients who are allergic to peanuts. Therefore, if you have been allergic to peanuts before, you should avoid eating them.

What should I do if I have skin allergies and itching?

Skin allergies and itching require actively searching for the triggering factors, i.e., allergens. Identifying what has irritated the skin and caused the allergic reaction is crucial, then avoiding further contact to prevent recurrence or worsening of the condition. If the allergy is triggered by consuming fish, shrimp, seafood, tropical fruits, etc., it is important to avoid eating similar foods in the future. If the use of certain cosmetics or skin care products causes allergies, avoid using other products containing the same ingredients. If the allergy is caused by certain medications, typically appearing within four days to a month of usage, it is advised to switch medications and avoid taking the same one again. For more severe allergic symptoms, such as significant itching, oral antihistamines like loratadine, desloratadine, cetirizine, and ebastine can be taken. Topical anti-itch medications like calamine lotion can be used, and for more severe conditions, topical corticosteroids or tacrolimus ointment can be applied. If symptoms do not improve or worsen with the aforementioned treatments, short-term oral steroids might be considered to manage the condition. (Note: Medication should be used under the guidance of a physician.)

What can you eat with skin allergies?

Skin allergies are caused by exposure to allergens. If skin allergies occur, it is best to check for allergens to see which foods or substances you are allergic to. Foods that do not cause allergic reactions upon testing or after consumption can be eaten. However, foods such as fish, shrimp, beef, lamb, seafood, eggs, and milk are more likely to cause allergies and should be avoided as much as possible.
