Man made drugs are a blessing, because they can eliminate your suffering and stop the symptoms of many lethal diseases. On the other hand, these drugs can result in some side effects. Sometimes these side effects can come in the shape of another disease e.g. angioedema also called quincke edema.
The most well known factor in causing angioedema is ACE inhibitor therapy which can cause ACEI Induced Angioedema. The symptoms may appear within a few hours or they may take years to become evident. If the symptoms appear, immediately withdraw the therapy and consult a doctor for prescription of steroids or antihistamines to counter the effect of the said therapy. Some other drugs which can cause angioedema are NSAIDS, aspirin, blood pressure medicines, ibuprofen, and antibiotics.
By avoiding these drugs you reduce the chances of angioedema attack.
