What are the allergic symptoms of amoxicillin granules?

Amoxicillin granules, a commonly used penicillin-class antibiotic, may cause allergic reactions in some individuals. Symptoms mainly include skin abnormalities, respiratory discomfort, gastrointestinal reactions, circulatory system manifestations, and mucosal involvement. The specific analysis is as follows:

1. Skin abnormalities: This is the most common allergic manifestation, typically beginning with skin itching, followed by redness, papules, or various forms of urticaria (hives), which may appear isolated or merge into larger patches. In severe cases, skin blisters, ulceration, or swelling of the face, eyelids, and other areas may occur, affecting appearance and local function.

2. Respiratory discomfort: When the allergic reaction affects the respiratory tract, symptoms such as nasal congestion, runny nose, and sneezing appear initially. As the condition progresses, chest tightness, shortness of breath, wheezing, throat tightness, and hoarseness may develop. If not treated promptly, laryngeal edema may occur, leading to difficulty breathing and potentially life-threatening consequences.

3. Gastrointestinal reactions: After gastrointestinal mucosa is irritated by the allergic reaction, nausea and vomiting occur, with vomitus usually consisting of stomach contents. Abdominal pain of varying severity may also accompany these symptoms, along with frequent diarrhea characterized by watery stools. Some individuals may show signs of dehydration due to persistent vomiting and diarrhea.

4. Circulatory system manifestations: Systemic disturbances caused by allergy can affect circulatory function, presenting as pallor, cold and clammy extremities, cold sweats, decreased blood pressure, and increased heart rate. Some people may experience dizziness and palpitations; in severe cases, this can progress to anaphylactic shock, manifesting as confusion, weak pulse, and other critical conditions.

5. Mucosal involvement: Oral mucosa may develop ulcers and erosion, causing pain that interferes with eating. When ocular mucosa is affected, symptoms include itchy, red, swollen eyes with excessive tearing and obvious conjunctival congestion; in severe cases, vision may be impaired.

Before using amoxicillin granules, individuals should clearly understand their allergy history—especially those allergic to penicillin-class drugs should avoid its use. If any of the above symptoms occur during treatment, medication should be stopped immediately and medical attention sought promptly. Always follow medical instructions when taking medication and do not adjust the dosage on your own.
