About Colonext-AD Dry Suspension

Colonext-AD Dry Suspension belongs to the class of medications called ‘antibiotics’ used to treat bacterial infections caused by susceptible Gram-negative bacteria. 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.

Colonext-AD Dry Suspension contains Colistin Sulphate. Colistin effectively solubilizes the bacterial cell membrane, resulting in bacterial cell death. As a result, Colonext-AD Dry Suspension destroys the bacteria and successfully treats the infection.

Take Colonext-AD Dry Suspension as prescribed by your doctor. Depending on your medical condition, you are advised to take Colonext-AD Dry Suspension for as long as your doctor prescribes it. Sometimes, you may experience common side effects like dizziness, upset stomach, rash, diarrhoea, vertigo (spinning sensation), paresthesia (tingling or pricking sensation) and slurred speech. 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 Colonext-AD Dry Suspension, let your doctor know about all your medical conditions, sensitivities, and all medications you are using.
