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.

Do you need to take medicine for skin allergies?

Whether or not you need to take medication for skin allergies depends on the amount and area of your allergies. If the allergic area is small and limited, we can generally use topical medications and avoid oral medications. However, if the allergic area is extensive and covers a large area, we usually recommend timely oral medications and, if necessary or in severe cases, intravenous administration.

Does skin allergy affect pregnancy?

When skin allergies occur, they do not affect the normal chances of pregnancy, but they do have some impact on the fetus after pregnancy. This is because skin allergies are reactions to certain allergens, and the response to allergens varies from person to person. Some individuals might have a higher sensitivity, while others may show little to no symptoms. Beyond the impacts these allergic reactions have on the body, there is also the use of medicinal solutions for treatment during allergic episodes. It is advised to identify the allergen causing the skin allergy before trying to conceive, and to avoid it as much as possible while planning for pregnancy.

How to deal with sunburned allergic skin?

Sunburned skin allergies are actually caused by the strong ultraviolet rays contained in sunlight. When ultraviolet rays shine on the skin, they can cause allergies and other damage to the skin. If sunburn-induced skin allergies occur, it is essential to avoid further exposure to sunlight and keep away from it. Secondly, keep the skin clean and avoid using irritating cleansing products. Finally, it is recommended to use cold compresses for treatment and apply some aloe vera gel to the affected areas of the skin.

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.)
