Patient leaflet - Daxas 250 micrograms tablets
1. What Daxas is and what it is used for
Daxas contains the active substance roflumilast, which is an anti-inflammatory medicine called phosphodiesterase-4 inhibitor. Roflumilast reduces the activity of phosphodiesterase-4, a protein occurring naturally in body cells. When the activity of this protein is reduced, there is less inflammation in the lungs. This helps to stop narrowing of airways occurring in chronic obstructive pulmonary disease (COPD). Thus Daxas eases breathing problems. Daxas is used for maintenance treatment of severe COPD in adults who in the past had frequent worsening of their COPD symptoms (so-called exacerbations) and who have chronic bronchitis. COPD is a chronic disease of the lungs that results in tightening of the airways (obstruction) and swelling and irritation of the walls of the small air passages (inflammation). This leads to symptoms such as coughing, wheezing, chest tightness or difficulty in breathing. Daxas is to be used in addition to bronchodilators.
2. What you need to know before you take Daxas
Do not take Daxas
if you are allergic to roflumilast or any of
the other ingredients of this medicine (listed in section 6)
if you have moderate or severe liver
problems.
Warnings and precautions

Sudden attack of breathlessness
Daxas is not intended for the treatment of a sudden attack of breathlessness (acute bronchospasms). In order to relieve a sudden attack of breathlessness it is very important that your doctor provides you with another medicine to be available to you at all times that can cope with such an attack. Daxas will not help you in this situation. Body weight

- The starting dose is a low dose used to help your body get used to the medicine before you start taking the full dose. At this low dose you will not get the full effect from the medicine – therefore it is important that you move on to the full dose (called a ‘maintenance dose’) after 28 days.
After 28 days - the recommended maintenance dose is one
500 micrograms tablet once daily. Swallow the tablet with some water. You may take this medicine with or without food. Take the tablet at the same time every day.

Do not take a double dose to make up for a forgotten dose.
