Precautions
| Condition / Situation | Precaution |
| Kidney impairment | Dose adjustment may be required to avoid drug buildup |
| Dehydration | Adequate fluid intake is important to support kidney function |
| Pregnancy | Use only if clearly advised after medical evaluation |
| Breastfeeding | Should be used carefully as medicine may pass into milk |
| Elderly patients | Higher sensitivity due to reduced kidney function |
Important Precautions
Kidney function plays a key role in drug elimination, so reduced kidney performance may increase medicine levels in the body and require careful dose management.
Adequate hydration is important during therapy to support proper kidney filtration and reduce risk of unwanted accumulation.
In pregnancy and breastfeeding, use is considered only when benefits clearly outweigh potential risks, based on clinical evaluation.
Elderly individuals may need closer monitoring due to naturally reduced kidney efficiency and higher sensitivity to medicine effects.
Any unusual symptoms such as confusion, dizziness, or behavioral changes should be reported promptly during treatment.
For recurrent infections, long-term use should be supervised to ensure safety and appropriate dose control.
