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

Talk to your doctor or pharmacist before taking Daxas.

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

You should check your body weight on a regular basis. Talk to your doctor if, while taking this medicine, you observe an unintentional loss of body weight (not related to a diet or exercise programme).

Other diseases

Daxas is not recommended if you have one or more of the following diseases:

  • severe immunological diseases such as HIV infection, multiple sclerosis (MS), lupus erythematosus (LE) or progressive multifocal leukoencephalopathy (PML)
  • severe acute infectious diseases such as acute hepatitis
  • cancer (except basal-cell carcinoma, a slow-growing type of skin cancer)
  • or severe impairment of the heart function

There is a lack of relevant experience with Daxas under these conditions. You should talk to your doctor, if you are diagnosed with any of these diseases.

Experience is also limited in patients with a previous diagnosis of tuberculosis, viral hepatitis, herpes viral infection or herpes zoster. Please talk to your doctor if you have one of these diseases.

Symptoms you should be aware of

You may experience diarrhoea, nausea, abdominal pain or headache during the first weeks of treatment with Daxas. Talk to your doctor if these side effects do not resolve within the first weeks of treatment.

Daxas is not recommended in patients with a history of depression associated with suicidal thinking or behaviour. You may also experience sleeplessness, anxiety, nervousness, or depressive mood. Before starting treatment with Daxas, inform your doctor if you are suffering from any symptoms of this kind and of any additional medicines you may take since some of those could increase the probability of these side effects. You or your caregiver should also immediately inform your doctor of any changes in behaviour or mood and of any suicidal thoughts you may have.

Children and adolescents

Do not give this medicine to children and adolescents under 18 years of age.

Other medicines and Daxas

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines, especially the following:

  • a medicine containing theophylline (a medicine to treat respiratory diseases), or
  • a medicine used for treatment of immunological diseases, such as methotrexate, azathioprine, infliximab, etanercept, or oral corticosteroids to be taken long-term.
  • a medicine containing fluvoxamine (a medicine to treat anxiety disorders and depression), enoxacin (a medicine to treat bacterial infections) or cimetidine (a medicine to treat stomach ulcers or heartburn).

The effect of Daxas may be reduced if taken together with rifampicin (an antibiotic medicine) or with phenobarbital, carbamazepine or phenytoin (medicines usually prescribed for the treatment of epilepsy). Ask your doctor for advice.

Daxas may be taken with other medicines used in the treatment of COPD such as inhaled or oral corticosteroids or bronchodilators. Do not stop taking these medicines or reduce their dose unless advised by your doctor.

Pregnancy and breast-feeding

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine. You should not become pregnant during treatment with this medicine and should use an effective method of contraception during therapy, because Daxas may be harmful for the unborn baby.

Driving and using machines

Daxas has no influence on the ability to drive and use machines.

Daxas contains lactose

If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking this medicinal product.

3. How to take Daxas

Always take this medicine exactly as your doctor has told you. Check with your doctor or pharmacist if you are not sure.

  • For the first 28 days - the recommended starting dose is one 250 micrograms tablet once daily.
    • 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.

You may need to take Daxas for several weeks to achieve its beneficial effect.

If you take more Daxas than you should

If you have taken more tablets than you should, you may experience the following symptoms: headache, nausea, diarrhoea, dizziness, throbbing of your heart, light-headedness, clamminess and low blood pressure. Tell your doctor or pharmacist straight away. If possible take your medicine and this leaflet with you.

If you forget to take Daxas

If you forget to take a tablet at the usual time, take the tablet as soon as you remember on the same day. If on one day you have forgotten to take a tablet of Daxas, just carry on the next day with the next tablet as usual. Continue taking your medicine at the usual times. Do not take a double dose to make up for a forgotten dose.

If you stop taking Daxas

It is important to continue taking Daxas for as long as prescribed by your doctor, even when you have no symptoms, in order to maintain control of your lung function.

If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
