Uses of Covent Syrup

Chronic obstructive pulmonary disease (COPD)

Benefits of Covent Syrup

Chronic obstructive pulmonary disease (COPD)
COPD (chronic obstructive pulmonary disease) is a group of lung diseases that cause breathing difficulties. COPD is caused by swelling of the airways that carry air in and out of the lungs. Covent Syrup relaxes the muscles of these airways and widens it. This makes you breathe easy and gives relief from symptoms such as tightness in your chest, shortness of breath, wheezing and coughing. Avoid smoking and minimise your exposure to pollution, dust and fumes. Along with that, a little exercise each day can help you stay strong. Talk to your doctor about how much exercise is good for you.

Side effects of Covent Syrup

Most side effects do not require any medical attention and disappear as your body adjusts to the medicine. Consult your doctor if they persist or if you’re worried about them
