Uses of Rexmax LS Syrup

Cough with mucus

Benefits of Rexmax LS Syrup

Cough with mucus
Rexmax LS Syrup gives relief from cough with mucus. It helps to loosen thick mucus, making it easier to cough out. It also relaxes the muscles of the airways and widens it. This makes breathing easy and reduces the frequency of coughing. Rexmax LS Syrup will also relieve allergy symptoms like watery eyes, sneezing, runny nose or throat irritation. Along with medications, drink enough luke warm water and gargle with warm salt water to ease the symptoms.

How to use Rexmax LS Syrup

Take this medicine in the dose and duration as advised by your doctor. Check the label for directions before use. Measure it with a measuring cup and take it by mouth. Shake well before use. Rexmax LS Syrup may be taken with or without food.

How Rexmax LS Syrup works

Rexmax LS Syrup is a combination of three medicines: Levosalbutamol, Ambroxol and Guaifenesin which relieve cough with mucus. Levosalbutamol is a bronchodilator. It works by relaxing the muscles in the airways and widens airways. Ambroxol is a mucolytic which thins and loosens mucus (phlegm), making it easier to cough out. Guaifenesin is an expectorant which decreases the stickiness of mucus (phlegm) and helps in its removal from the airways.
