The key points that cannot be ignored in the side effects of avacopan

Avacopan (avacopan) is a drug designed to treat granulomatosis with polyangiitis (also known as Wegener's granulomatosis) and microscopic polyangiitis in adults. These two diseases are autoimmune diseases that cause the body's immune system to mistakenly attack its own veins and other blood vessels, causing damage to important organs such as the heart and lungs. Avacopan, a complement inhibitor, works by blocking parts of the immune system that may damage blood vessels, thereby reducing inflammation and vascular damage.

However, avacopan may also cause some side effects during treatment. Common side effects include digestive complaints such as tiredness, nausea, diarrhea, vomiting, and stomach pain, as well as systemic symptoms such as rash, headache, and dizziness. Some patients may also experience blurred vision, neck or ear pain, burning or stinging sensations, or even elevated blood creatinine levels, which may indicate some impact on kidney function.

More serious side effects, although relatively rare, require prompt medical attention if they occur. Patients should seek emergency medical help immediately if they develop signs of an allergic reaction, such as hives, difficulty breathing, or swelling of the face or lips. In addition, avacopan may cause liver problems, which may manifest as loss of appetite, stomach pain or swelling, leg swelling, easy bleeding, drowsiness, confusion, or jaundice. At the same time, signs of serious infection should not be ignored, such as fever, cold symptoms, flu symptoms, earache, painful urination, or cold sores in the mouth or throat.

It should be emphasized that the above is not a complete list of avacopan's side effects, and patients may also experience other unmentioned side effects during use. Therefore, while taking avacopan, patients should pay close attention to their physical condition. If there are any abnormal reactions, they should communicate with their doctor in time and adjust the treatment plan.
