Magnistin 4.5 MIU Injection contains Colistimethate Sodium. It is an antibiotic medication used when other drugs or therapy are ineffective.

As a result, Magnistin 4.5 MIU Injection kills the bacteria and effectively treats the infection. In addition, it can also treat infectious diarrhoea and urinary tract infections.

About Magnistin 4.5 MIU Injection

Magnistin 4.5 MIU Injection belongs to the class of medications called ‘antibiotics’ used to treat bacterial infections. Bacterial infections are caused by the multiplication of harmful bacteria inside or on the body. These harmful bacteria produce chemicals known as toxins, which can damage tissue and make you sick. Symptoms of bacterial infection vary depending on the organ affected by bacteria.

Magnistin 4.5 MIU Injection contains Colistimethate Sodium. Colistimethate Sodium effectively solubilizes the bacterial cell membrane, resulting in bacterial cell death. As a result, Magnistin 4.5 MIU Injection destroys the bacteria and successfully treats the infection.

Magnistin 4.5 MIU Injection will be administered by a qualified healthcare professional. Sometimes, you may experience common side effects like injection site reactions, renal damage, visual disturbances, GI disturbances, dizziness, nausea, vomiting and muscle weakness. But these side effects are usually in the initial phase and resolve over time. However, if these side effects persist, let your doctor know.

Before receiving Magnistin 4.5 MIU Injection, let your doctor know about all your medical conditions, sensitivities, and all medications you are using. And also, inform your doctor if you are pregnant, planning pregnancy, or breastfeeding. Magnistin 4.5 MIU Injection can cause blurred vision and dizziness in some people; if this occurs, do not drive or operate tools or machinery. It is recommended not to consume any alcoholic beverages while on treatment with this medicine.
