Benefits of CNF Activ Suspension

Sneezing and runny nose due to allergies
CNF Activ Suspension is used to treat an itchy, stuffy or runny nose, sneezing, or other symptoms caused by seasonal hay fever (allergic rhinitis). It works by reducing certain substances in the body called histamines that are responsible for the allergic symptoms. It also reduces swelling inside the nose and thus decreases symptoms such as stuffy nose. This helps in easy breathing and makes you feel better.
