Norflox 400 tablets contain Norfloxacin, an antibiotic used to treat bacterial infections, especially those affecting the urinary tract, intestines, and prostate. It is also effective in treating certain sexually transmitted infections. This medicine works by stopping the growth of bacteria, helping your body clear the infection.
You should take Norflox 400 exactly as your doctor prescribes. The dosage and length of treatment will depend on your specific condition, age, and individual response to the medication. Even if you start feeling better after a few days, continue taking the tablets for the full course to ensure the infection is completely treated and to prevent resistance.
Some common side effects of Norflox 400 may include stomach cramps, nausea, headache, and dizziness. These effects are usually mild and go away on their own. However, if any of these symptoms persist or become bothersome, you should consult your doctor.
In rare cases, Norfloxacin can increase the risk of tendon-related issues such as pain, swelling, or inflammation, especially in older adults, those taking steroid medications, or people who have had organ transplants. If you experience any unusual pain around joints, such as the ankle, shoulder, or elbow, stop taking the medicine and inform your doctor immediately.
