Angioedema is swelling beneath the skin, often caused by allergic reactions, certain medications, infections, or underlying medical conditions. Triggers include foods, insect stings, or drugs like ACE inhibitors. Symptoms may involve swelling of the lips, eyes, tongue, or throat, sometimes leading to breathing difficulties. Treatment depends on the cause: antihistamines and corticosteroids help allergic cases, while severe attacks may require epinephrine. Avoiding known triggers is key. Chronic angioedema may need long-term therapies such as biologics. If infection is suspected, antibiotics like cephalexin capsules may be prescribed. For medical facilities, finding a trusted
cephalexin capsules supplier ensures timely treatment options.
