Product introduction

LABCHLOR 1GM INJECTION is used to treat critically ill patients admitted to the hospital. It may be effective even when bacteria have developed resistance to other antibiotics. This medicine is given by drip or by direct injection into a vein, under the supervision of a doctor or nurse. The dose will depend on what type of infection you have, where it is in the body, and how serious it is. You should keep on taking the injection for as long as you are prescribed, even if your symptoms quickly improve. If you stop taking it too early the infection may return or worsen.

Some people may develop side effects like nausea, vomiting, diarrhea, taste change, or local redness and swelling at the site of injection. These side effects are usually temporary and go away during treatment as your body adjusts to the medicine. Consult your doctor if these side effects bother you or do not go away.

Before starting treatment with this medicine, you should tell your doctor if you have liver or kidney problems or if you are allergic to any antibiotic. While using it, your doctor may advise some blood tests to monitor your blood cell counts. Pregnant and breastfeeding mothers should consult their doctor before using it.
