Swelling of the lips in hives is commonly due to acquired angioedema, which can be treated by actively searching for allergens and avoiding contact with them, as well as by taking antihistamines.
Allergic reactions can be caused by contact with certain allergens in allergic organisms. Localized edema occurs in the skin of the lip area due to increased permeability of the blood vessels of the skin and mucous membranes. To relieve lip swelling, the first step is to identify and avoid allergens. If lip swelling is severe, anti-allergy treatment can be given with antihistamines such as cetirizine and loratadine.
If the symptoms do not improve after being removed from the current environment, it is necessary to go to the hospital immediately to avoid life-threatening complications such as laryngeal edema caused by the aggravation of the allergic reaction. All of the above medications should be used in accordance with medical advice.
