Angioedema, characterized by swelling beneath the skin, is often treated based on its cause. For allergic angioedema, antihistamines and corticosteroids reduce swelling and itching. In severe cases, epinephrine may be required. Hereditary angioedema may need C1 inhibitor replacement or drugs like icatibant. For drug-induced cases, discontinuing the offending medication, such as ACE inhibitors, is key. The cephalexin capsules, an antibiotic, may be prescribed if a bacterial infection triggers angioedema, though it’s not a primary treatment. Chronic cases might require immunosuppressive therapy. Always consult a healthcare provider for tailored treatment, as angioedema can be life-threatening if airway swelling occurs.
