Is Martifur effective?
Martifur is an antibiotic that works in many ways to stop bacteria from growing. It messes with several important parts of a bacteria's life, making it hard for them to survive.

Even after taking it for a week, a significant amount of the medicine is still found in the urine, showing that it effectively reaches the urinary tract where it's needed to fight infection.

How does one know if Martifur is working?
Martifur's effectiveness against bacteria is checked using a lab test. The test measures how much of the drug is needed to stop the bacteria's growth.

However, there aren't enough studies to prove it works against *every* type of bacteria the test says it should.
