1. What Visclair Tablets are and

Visclair tablets contain a medicine called
mecysteine hydrochloride. This reduces the
thickness and amount of mucus produced
in the lungs. Mucus is a coating that lines
the internal surface of the lungs.
Visclair is used together with other
medicines to help in the treatment of
conditions in which thick mucus is a problem
e.g. chronic obstructive pulmonary disease
(a condition of the lungs causing difficulty
breathing), sinusitis (inflamed nasal tubes),
secretory otitis media (discharge from the
middle ear) and in the symptomatic relief of
cough with sputum or phlegm.

before you take your medicine.
