Certain medicines, such as ACE inhibitors, ARBs, NSAIDs, and some antibiotics, can trigger angioedema in sensitive individuals. Symptoms may include facial swelling, difficulty breathing, or abdominal pain, requiring immediate medical attention. Safer choices often include alternative blood pressure medications, non-NSAID pain relievers, or carefully selected antibiotics. For instance, if a patient is allergic to penicillin, cephalosporins like cephalexin should be used with caution, though they are generally safer for many patients. Reliable sourcing of medications is also crucial. A trusted cephalexin capsules supplier ensures quality and consistency, reducing the risk of adverse reactions linked to contaminated or substandard drugs.
