【Contraindications】Disabled for patients who are allergic to this product and fluoroquinolone. 
1. This product should be taken on an empty stomach, and drink 25Oml at the same time. 
2. Since Escherichia coli is more common in norfloxacin-resistant patients, urine specimens should be kept before administration, and the drug sensitivity should be adjusted according to the results of bacterial susceptibility. 
3. Crystallized urine can occur when the product is used in large doses or when the urine pH value is above 7. In order to avoid the occurrence of crystallized urine, it is advisable to drink more water and keep the urine output for more than 1200ml for 24 hours. 
4. Patients with renal dysfunction need to adjust the dose according to renal function. 
5. The application of fluoroquinolone drugs may occur after moderate and severe photoexgregation. Excessive exposure to sunlight should be avoided when applying this product. If photosensitive reaction occurs, stop the drug. 
6. Glucose-6-phosphate dehydrogenase deficiency patients taking this product, very likely to have a hemolysis reaction. 
7. Quinolones include this product can cause aggravation of myasthenia gravis, respiratory muscle weakness and life-threatening. The use of quinolones in patients with myasthenia gravis should include special products. 
8. When liver function declines, such as severe (cirrhosis ascites) can reduce drug clearance, blood drug concentration is increased, liver and kidney function are all reduced, especially after weighing the pros and cons and applying dose adjustment. 
9. Patients with original central nervous system diseases, such as those with epilepsy and epilepsy history, should avoid application. When there are indications, they should be carefully weighed against the pros and cons. 
10. Disabling and potentially irreversible serious adverse effects, including tendinitis and tendon rupture, peripheral neuropathy, and effects of the central nervous system. The use of fluoroquinolone drugs has been reported to cause disabling and potentially irreversible serious adverse reactions in different organ systems of the same patient, usually including: tendonitis, tendon rupture, joint pain, myalgia, peripheral neuropathy and Central nervous system response (illusion, anxiety, depression, severe headache and confusion). These defects should occur after hours to weeks after the use of norfloxacin capsules. These adverse events have been reported in patients of any age without prior risk factors. 
11. Tendons and tendon ruptures Fluoroquinolone drugs increase the risk of tendonitis and tendon rupture in patients of all ages. This adverse reaction most often occurs in the Achilles tendon, which may require surgical repair. There have also been reports of tendonitis and tendon rupture in the shoulders, hands, biceps, thumb and other tendon points. Tendinitis and tendon rupture can occur hours or days after the start of the use of norfloxacin capsules, or months after the end of treatment. Tendinitis and tendon rupture occur on the side. This risk is further increased in elderly patients over 60 years of age, patients taking corticosteroids, and patients undergoing kidney, heart or lung transplants. In addition to age and the use of corticosteroids, factors that independently increase the risk of tendon rupture include severe physical activity, renal failure, and previous tendon diseases such as rheumatoid arthritis. Tendinitis and tendon rupture also occur in patients who use fluoroquinolone drugs without the above risk factors. Tendon rupture can occur during or after treatment; it is also reported that tendon rupture occurs several months after the end of treatment. This product should be discontinued after the patient has muscle pain, swelling, inflammation or breakage.
