Swollen hands from ant bites are common in insect bite dermatitis, which can be treated with topical medications as well as oral medications. 1. Topical medication: you can use soapy water to rinse the wound, and apply glucocorticoid ointment locally, such as mometasone furoate cream, dianabed ointment, and so on. 2. Oral medication: If the itching is significant, you can take oral antihistamines such as loratadine, cetirizine and other anti-allergy treatment. If the symptoms are more serious, you can take a small dose of oral glucocorticosteroids, such as prednisone, to control the inflammatory reaction. If the above symptoms occur, it is recommended to go to the hospital to find a doctor for treatment, and the specific medication should follow the doctor’s instructions.
