Allergic herpes mainly refers to a symptom of allergic dermatitis, mainly with blisters and pustules as the main clinical symptoms. For treatment, you can choose oral medication with topical medication, because the disease itself is caused by allergic factors, so oral desensitizing drugs are very important, such as cetirizine tablets, loratadine tablets, while choosing to use this desensitizing drug to improve itching symptoms, you also need to take oral vitamin C or calcium gluconate oral solution, which can effectively stabilize mast cells and can play an auxiliary therapeutic role. For topical medications, it is recommended to choose glycolic lotion or zinc oxide cream, both of which can effectively dry out allergic blisters and relieve itching symptoms, thus achieving the desired therapeutic effect. If necessary, you can also apply Denide cream or Mometasone furoate cream directly after the blisters have dried up, which has a very good therapeutic effect.
