1. What Uniphyllin Continus tablets
are and what they are used for
These tablets are used to treat asthma,
long-term breathing difficulties such
as chronic obstructive pulmonary
disease and chronic bronchitis, and are
sometimes used to treat heart failure.
They contain the active ingredient
theophylline which belongs to a group
of medicines called bronchodilators.
Bronchodilators help stop you wheezing
and being breathless. Theophylline also
reduces swelling in the lungs of asthma
patients and relieves the feeling of
‘tightness’ in their chest.
These tablets may be taken by adults
and children aged 6 years and above.

under 6 months of age or if they are
also taking a cough medicine or if they
