What are the side effects of norfloxacin capsules?

Norfloxacin capsules belong to the quinolone class of antibacterial drugs and are primarily used to treat various infections caused by susceptible bacteria, such as prostatitis, enteritis, and urinary tract infections. Common side effects include central nervous system disturbances, allergic reactions, hepatobiliary abnormalities, musculoskeletal discomfort, and hematological system disturbances.

1. Central nervous system disturbances: Improper use of the drug may damage the central nervous system, leading to side effects such as agitation, anxiety, seizures, and insomnia.

2. Allergic reactions: The main active ingredient is norfloxacin. In patients with weak constitutions or those who are inherently prone to allergies, this medication may trigger hypersensitivity reactions such as urticaria, itching, breathing difficulties, and anaphylactic shock.

3. Hepatobiliary abnormalities: The active components of norfloxacin capsules are metabolized in the liver. In patients with pre-existing conditions such as hepatitis or cirrhosis, indiscriminate use of the drug may worsen their condition or lead to adverse reactions such as acute hepatic necrosis and liver failure.

4. Gastrointestinal discomfort: Taking norfloxacin capsules on an empty stomach or in excessive doses may irritate the gastrointestinal tract, increasing gastric motility, causing abnormal gastric acid secretion, or inducing intestinal smooth muscle spasms, resulting in side effects such as diarrhea, nausea, and pain.

5. Hematological system disturbances: Norfloxacin capsules may damage blood components such as hematopoietic stem cells, platelets, and white blood cells, leading to hematological side effects such as thrombocytopenia, leukopenia, and aplastic anemia.

Individuals allergic to norfloxacin or other quinolone antibiotics should not use norfloxacin capsules. Therefore, patients should consult a physician before using this medication to avoid inappropriate or blind use.
