Daliresp (Roflumilast) – Patient Information (Australia)

Daliresp contains roflumilast, a medicine used to help reduce symptoms and flare-ups (exacerbations) in certain people with long-term lung disease. This page explains how it works, how to use it safely, what to expect, and practical tips to support your treatment.

Note: This information is designed to be patient-friendly and educational. Always follow the instructions provided by your healthcare professional and read the product label/consumer medicine information supplied with your medicine.

Basic product information

What Daliresp is used for (indications)

Daliresp (roflumilast) is used as an add-on maintenance treatment for people with chronic obstructive pulmonary disease (COPD) who are at risk of exacerbations.

In typical clinical use, roflumilast may be considered when you have:

• Severe to very severe COPD (as assessed by your clinician)
• Chronic bronchitis (long-term cough with mucus)
• A history of frequent flare-ups (exacerbations)

Important: Daliresp is not a reliever medicine for sudden breathlessness. It is intended to support long-term control of COPD.

How roflumilast works (mechanism of action)

Roflumilast helps reduce inflammation in the airways by inhibiting an enzyme called phosphodiesterase-4 (PDE4).

• PDE4 normally breaks down cAMP (a molecule involved in inflammatory signalling).
• By blocking PDE4, roflumilast helps increase intracellular cAMP.
• This reduces release of certain inflammatory mediators and may improve airflow and reduce flare-ups in suitable COPD patients.

Because it targets inflammation, some benefits are seen over days to weeks rather than immediately after a dose.

Pharmacokinetics (how the body handles the medicine)

Understanding timing and metabolism can help explain when you may notice effects and how side effects may occur.

Absorption

• Roflumilast is absorbed after taking a tablet.
• Peak levels in the blood typically occur within a few hours after dosing.

Metabolism

• Roflumilast is metabolised mainly by liver enzymes, including CYP1A2 and CYP3A4.
• It has an active metabolite (roflumilast N-oxide) that contributes to overall effect.

Distribution and elimination

• Roflumilast and its metabolite are eliminated primarily via the kidneys and/or bile (metabolite clearance).
• The drug’s half-life is long enough that it is taken once daily in most regimens.

Practical implication: If you miss a dose, do not take a double dose to “catch up” unless your healthcare professional advises otherwise.

Typical use and treatment timing

Daliresp is usually used as part of a broader COPD plan that may also include bronchodilators (often inhalers) and other maintenance medicines.

When to take it

• Most people take roflumilast once daily, at the same time each day.
• Some people prefer taking it with food or at a consistent time to improve stomach comfort (see “Food interactions” below).

How quickly it may help

• It is not a rescue medicine.
• Improvement, if it occurs, may take days to weeks.
• It is common for clinicians to reassess symptoms and flare-up frequency after a period of regular use.

Dosing (adult use guidance)

Dosing can vary depending on your condition and your tolerance to side effects. Always use the dose prescribed for you.

Common approach

• Initial dosing may start lower and then increase to reduce side effects such as nausea, diarrhoea, or weight loss.
• A commonly used regimen for many patients is 500 micrograms once daily after an initial titration period (confirm your personal instructions).

Missed dose

• If you miss a dose, take it when you remember on the same day.
• If it is close to your next dose, skip the missed dose and continue your schedule.
• Do not double doses.

Stopping treatment

Do not stop suddenly without discussing with your healthcare professional. If you are experiencing side effects or your symptoms worsen, seek advice promptly.

Food interactions and absorption

Food can influence how comfortable roflumilast is for some people.

• General guidance: Roflumilast may be taken with or without food.
• If you experience nausea or stomach upset: taking it with food may help.
• Try to maintain a consistent routine (e.g., always with a meal) if you notice a pattern.

Allergy and sensitivities: Check your tablet ingredients if you have known sensitivities.

Alcohol and medicine interactions

Before starting Daliresp, review all medicines and supplements you use, including medicines from pharmacies, health stores, and non-prescription products.

Alcohol

• Alcohol may worsen symptoms like breathlessness, stomach irritation, and dizziness in some people.
• There is not usually a specific “dangerous interaction” solely from alcohol, but safer use typically means limiting alcohol, especially if you have side effects from roflumilast (e.g., nausea, diarrhoea, headache).
• If you notice symptoms after drinking, consider reducing or avoiding alcohol and talk to your clinician.

Common medicine interaction themes

Roflumilast is metabolised by liver enzymes, so medicines that affect those enzymes can change roflumilast levels.

• Enzyme inducers (medicines that increase liver enzyme activity) may reduce roflumilast effectiveness.
• Enzyme inhibitors may increase roflumilast levels and side effect risk.

Examples of interacting medicines (talk to your clinician/pharmacist)

• Smoking: Cigarette smoke can induce certain enzymes (notably CYP1A2), potentially lowering roflumilast exposure. If you smoke, discuss this with your clinician and consider smoking cessation support.
• Antibiotics/antifungals: Some agents that inhibit or induce enzymes may require monitoring or dose adjustment.
• Antiepileptics and some other long-term medicines: can act as enzyme inducers.
• Other PDE4 inhibitors: avoid duplication unless specifically directed.

Always check: Bring a list of your medicines (including inhalers, tablets, herbal products, vitamins, and supplements) to your pharmacy appointment for a full interaction check.

Safety profile and side effects

As with all medicines, Daliresp can cause side effects. Not everyone gets them. Many are dose-related and can improve after dose adjustment or with supportive care.

Common side effects

• Diarrhoea
• Nausea
• Weight loss
• Headache
• Abdominal discomfort (stomach pain or cramps)
• Loss of appetite
• Dizziness (in some people)

Serious side effects (seek urgent medical advice)

• Severe, persistent diarrhoea leading to dehydration
• Marked weight loss or signs of malnutrition
• Worsening mood changes, including new or worsening depression, anxiety, or suicidal thoughts (any sudden changes should be assessed promptly)
• Allergic reactions (such as swelling of the face/lips, breathing difficulty, rash/hives)

Who should take extra care?

• People with a history of depression or mood disorders
• People who are at risk of weight loss or who are underweight
• People with significant gastrointestinal conditions or who have had severe diarrhoea with prior medicines
• People with liver problems or other complex medical conditions—your clinician may adjust the plan or monitor more closely

Practical use tips for everyday life

Start gently and track symptoms

• When beginning or increasing dose, expect that side effects such as nausea or diarrhoea may occur.
• Keep a simple daily note: stool frequency, appetite/weight changes, and any mood symptoms.
• If side effects are troublesome, contact your healthcare professional early—often adjustments can be made.

Manage stomach effects

• Consider taking the tablet with food if you experience nausea.
• Stay hydrated, especially if diarrhoea occurs.
• Avoid heavy, greasy meals if they worsen symptoms.

Watch your weight

• Regularly monitor your weight (for example weekly at first).
• If you notice unintentional weight loss, speak with your clinician promptly.

Mood and mental wellbeing

• If you notice low mood, agitation, or unusual thoughts, seek advice as soon as possible.
• Don’t wait for symptoms to “pass” if they are intense or worsening.

Use alongside inhalers and COPD plans

• Daliresp works differently from inhalers. Continue your other COPD medicines as prescribed.
• Use your reliever inhaler for sudden breathlessness as instructed in your action plan.

When to seek medical attention

• If you get signs of a COPD flare (worsening breathlessness, increased sputum, fever, or chest tightness) that are not responding to your usual plan.
• If diarrhoea is severe or causing dizziness, weakness, or reduced urine output.
• If you experience a rash, facial swelling, or trouble breathing.

Alternative options for COPD (discuss with your clinician)

COPD treatment is tailored to symptoms and flare-up risk. Alternatives depend on your lung function and history of exacerbations.

Maintenance medicines commonly considered

• Inhaled bronchodilators (short-acting and long-acting)
• Inhaled corticosteroids for selected patients (often in combination therapy)
• Combination inhaler therapies that improve airflow and reduce exacerbations
• Other anti-inflammatory or preventive approaches may be considered depending on your profile

Supportive non-medicines

• Smoking cessation (if applicable) is one of the most effective steps to slow COPD progression.
• Pulmonary rehabilitation to improve exercise tolerance and quality of life.
• Vaccinations (e.g., influenza and pneumococcal) as advised for COPD patients.

Your clinician can help determine which option best matches your symptoms, exacerbation history, and tolerance of medicines.
