Drug-induced angioedema is a type of angioedema that is caused by the use of certain medications. It is a serious condition that can cause swelling in various parts of the body, including the face, throat, and abdomen.

Causes

Drug-induced angioedema is most commonly caused by ACE inhibitors, a type of medication used to treat high blood pressure and heart failure. Other medications that can cause this condition include NSAIDs, aspirin, and certain antibiotics.

Symptoms

The symptoms of drug-induced angioedema can vary depending on the area of the body that is affected. Common symptoms include:

• Swelling of the face, lips, tongue, or throat
• Difficulty breathing or swallowing
• Abdominal pain
• Nausea and vomiting

Diagnosis

Diagnosis of drug-induced angioedema is typically based on a patient's medical history and a physical examination. If a patient has recently started taking a new medication and is experiencing symptoms of angioedema, the medication may be the cause.

Treatment

Treatment for drug-induced angioedema involves stopping the use of the medication that is causing the condition. In severe cases, emergency treatment may be required to ensure the patient can breathe properly. This can include intubation or a tracheostomy.

Prevention

Prevention of drug-induced angioedema involves avoiding the use of medications that are known to cause the condition. If a patient has a history of angioedema, they should inform their doctor before starting any new medications.
