Introduction

Common side effects of ribavirin granules include hemolytic anemia, gastrointestinal discomfort, skin allergic reactions, abnormal liver function, and neurological symptoms. The side effects of ribavirin granules vary significantly among individuals; therefore, regular monitoring of complete blood count, liver and kidney function, and clinical manifestations is necessary during treatment. If any of the above severe reactions or contraindications occur, the drug should be discontinued immediately and medical advice should be sought.

1. Hemolytic Anemia

The drug may disrupt the stability of red blood cell membranes, leading to red blood cell rupture. Patients may experience symptoms such as fatigue, pallor, and dizziness. Blood tests may show decreased hemoglobin levels. Regular monitoring of complete blood count is necessary, and discontinuation of the drug may be required if needed.

2. Gastrointestinal Discomfort

The drug can irritate the gastrointestinal mucosa, causing digestive disturbances. Symptoms include nausea, vomiting, abdominal pain, and diarrhea. These symptoms are usually mild, and taking the medication after meals can reduce mucosal irritation and alleviate discomfort.

3. Skin Allergic Reactions

The body may mount an immune response to the drug components, affecting the skin. Manifestations include rashes, itching, and erythema. In severe cases, allergic purpura may occur. The drug should be discontinued immediately upon onset, and antiallergic medications should be administered.

4. Abnormal Liver Function

The drug is metabolized in the liver and may damage hepatocytes, resulting in elevated transaminase levels. Some patients may develop symptoms such as fatigue, loss of appetite, and jaundice. Liver function should be regularly monitored during treatment, and concomitant use with other hepatotoxic drugs should be avoided.

5. Neurological Symptoms

The drug may affect neurotransmitter metabolism in the central nervous system, leading to headache, dizziness, insomnia, or drowsiness. These symptoms are mostly transient and resolve spontaneously after discontinuation. Extra caution is advised for individuals who drive or operate precision machinery.

Side effects of ribavirin granules vary significantly among individuals. Regular monitoring of complete blood count, liver and kidney function, and clinical manifestations is essential during treatment. If any of the above severe reactions or contraindications occur, the drug should be discontinued immediately and medical advice sought. Mild reactions may allow continued treatment under close observation. Pediatric dosing must strictly follow weight-based calculations to prevent misuse.
