What is nalidixic acid for?

Antibiotics such as nalidixic acid will not affect viral infections such as fever and influenza. Taking unnecessary antibiotics puts you at risk of making your body more susceptible to infections that are resistant to antibiotic treatment in the future. Use this medication according to your doctor's instructions.
