References荨麻疹通常表现为瘙痒的风团，偶尔伴有深层皮肤肿胀，主要通过避免已知的触发因素来控制。首选治疗是使用第二代 H1 抗组胺药，必要时可加大剂量。若需要，还可联合使用第一代 H1 抗组胺药、H2 抗组胺药、白三烯受体拮抗剂、强效抗组胺药以及短疗程的皮质类固醇。对于症状持续的患者，可考虑转诊至专科，采用奥马珠单抗 (omalizumab) 或环孢素等替代疗法。
Urticaria, often characterized by itchy wheals and sometimes swelling of the deeper skin layers, is typically managed by avoiding triggers, if known. The primary treatment involves second-generation H1 antihistamines, which can be adjusted to higher doses if needed. Additionally, other medications like first-generation H1 antihistamines, H2 antihistamines, leukotriene receptor antagonists, potent antihistamines, and short courses of corticosteroids may be used alongside. For persistent cases, referral to specialists for alternative therapies like omalizumab or cyclosporine may be considered.

Second-generation H1-antihistamines (e.g., cetirizine, loratadine, fexofenadine), Omalizumab, Ciclosporin, and short courses only of systemic corticosteroids
Angioedema 是指按压时不会留下凹坑的肿胀，发生在皮肤或粘膜下层。它通常影响面部、嘴唇、颈部和四肢，以及口腔、喉咙和肠道等部位。当它影响喉咙时就会变得危险，可能会导致危及生命的情况。
Angioedema is non-pitting edema that involves subcutaneous and/or submucosal layers of tissue that affects the face, lips, neck, and extremities, oral cavity, larynx, and/or gut. It becomes life-threatening when it involves the larynx.

预防的关键是避免诱发因素。治疗通常使用抗组胺药，如苯海拉明和雷尼替丁。严重时可使用皮质类固醇或白三烯受体拮抗剂。保持环境凉爽也有帮助。对于持续超过六周的病例，可考虑使用环孢素等免疫抑制剂。
这是一种常见疾病，约 20% 的人曾受其影响。急性荨麻疹在男女中的发病率相同，而慢性病例在女性中更常见。急性荨麻疹多见于儿童，慢性荨麻疹多见于中年人。若病程超过两个月，往往会持续数年后自行消退。
○ 治疗 - 非处方药
急性荨麻疹通常在一周内自行消退，慢性荨麻疹可能持续数年，尽管大多数患者最终会痊愈。若为慢性荨麻疹，建议定期服用抗组胺药，待症状自行缓解。
非处方抗组胺药。西替利嗪或左西替利嗪比非索非那定更有效，但可能导致嗜睡。
#Cetirizine [Zytec]
#LevoCetirizine [Xyzal]
对于慢性荨麻疹，首选非嗜睡的抗组胺药，如非索非那定。
#Fexofenadine [Allegra]
#Diphenhydramine [Benadryl]
#Loratadine [Claritin]
