Daliresp (Roflumilast) – Patient-Friendly Medicine Information (Australia)
Daliresp is a medicine used to help manage certain breathing conditions by reducing inflammation and relaxing pathways in the lungs. If you have been advised to use roflumilast, this guide explains what it does, how it works, how to take it, and what to watch for. It also covers important interactions and practical tips to support safe, effective use in Australia.
At a Glance
- Medicine: Daliresp (roflumilast)
- Common forms: Tablets
- Typical strengths: 250 micrograms (µg) and 500 micrograms (µg)
- Used for: Severe COPD with chronic bronchitis and a history of exacerbations
- Key benefits: Helps reduce flare-ups (“exacerbations”) and improve long-term control in appropriate patients
- How it’s taken: Usually once daily (often with a short titration plan at the start)
Basic Product Information
Active ingredient: roflumilast
Medicine class: Phosphodiesterase-4 (PDE4) inhibitor
How it works in the body: Roflumilast reduces inflammatory signalling and supports smoother lung function, particularly in chronic inflammatory airway diseases.
Where it fits: Daliresp is generally considered an “add-on” medicine for long-term management in selected people with severe COPD who experience frequent exacerbations.
Mechanism of Action (How Daliresp Works)
Roflumilast is a PDE4 inhibitor. PDE4 is an enzyme found in immune and inflammatory cells and is involved in breaking down intracellular signalling molecules (particularly cyclic AMP, or cAMP).
By inhibiting PDE4, roflumilast:
- Increases cAMP inside certain cells
- Reduces the release of inflammatory mediators (including cytokines)
- Helps lower lung inflammation that contributes to COPD symptoms and exacerbations
What this means for you: Daliresp is designed to improve long-term control and help prevent COPD flare-ups. It is not intended as a rescue medicine for sudden shortness of breath.
Typical Use in COPD
Daliresp (roflumilast) is used to reduce the risk of COPD exacerbations in specific patients—especially those with:
- Severe COPD
- Chronic bronchitis (e.g., ongoing cough with mucus)
- A history of exacerbations (frequent or recent flare-ups)
In practice, many people who use Daliresp also use standard COPD therapies such as inhaled bronchodilators and inhaled corticosteroids, depending on their individual condition.
How and When to Take Daliresp
Typical dosing approach
Many patients start on a lower dose and then increase, to help reduce side effects such as nausea, diarrhoea, or abdominal discomfort. Follow the exact dosing plan given to you.
Common titration (example guidance):
- Start with 250 micrograms once daily for a period recommended by your clinician
- Then increase to 500 micrograms once daily if tolerated
Timing
- Once daily at about the same time each day
- If you notice stomach symptoms, some people find it easier to take at a time when they can be near food
How to take the tablet
- Swallow tablets whole with water
- Do not crush or chew unless your pharmacist or clinician advises it
Missed dose
If you miss a dose, take it when you remember—unless it is close to the next dose. Do not take double doses.
Food Interactions and What to Eat
Food does not typically require special restrictions with roflumilast. In many cases, it can be taken with or without food.
However, because gastrointestinal side effects (such as nausea or diarrhoea) can occur—especially during the start of treatment—taking Daliresp with meals may help some people feel more comfortable.
- Tip: If you experience nausea, try taking the tablet with your main meal.
- Stay hydrated: If diarrhoea occurs, drink fluids as advised.
Alcohol and Medicine Interactions
Alcohol
There is no universal “safe amount” of alcohol with roflumilast. Alcohol may worsen stomach irritation and fatigue, and COPD symptoms can be affected by alcohol-related sleep and breathing changes.
- Practical approach: Limit alcohol and avoid heavy drinking.
- Stop and seek advice if alcohol plus Daliresp seems to significantly worsen side effects.
Medicine interactions (important)
Tell your pharmacist or doctor about all medicines you take, including over-the-counter products, vitamins, herbal supplements, and inhalers. Some interactions are particularly important with roflumilast.
Notable interaction classes:
- Medicines that affect drug metabolism (the liver enzymes that process roflumilast), which may require dose adjustments or avoidance in some situations
- Other medicines that can affect gastrointestinal tolerance, which may increase the chance of nausea or diarrhoea
- Medications associated with mood effects, since roflumilast may affect mood in some people
Examples to consider
Some commonly used medicines can interact, including certain antibiotic or seizure medicines, and other drugs that alter liver enzyme activity. Your local pharmacist can quickly check your specific regimen for interactions.
Always check: If you are taking medicines such as:
- CYP enzyme inducers/inhibitors (ask your pharmacist which medicines fall into this group)
- Medicines that may increase side effects when combined
Pharmacokinetics (What Happens to the Medicine in the Body)
Understanding the basic pharmacokinetics can help explain timing and side effects.
- Absorption: Roflumilast is absorbed after oral administration.
- Metabolism: The medicine is processed mainly in the liver. It forms active metabolites.
- Distribution: It distributes throughout the body tissues to varying degrees depending on protein binding.
- Elimination: It is cleared from the body largely through metabolic pathways and excretion.
Why this matters: Because metabolism occurs in the liver, liver-related issues can affect how roflumilast is handled. Always inform healthcare professionals about liver disease or abnormal liver blood tests.
Indications (When Daliresp Is Used)
Daliresp is indicated for reducing exacerbations in patients with severe COPD associated with chronic bronchitis and frequent exacerbations despite appropriate standard therapy.
It is intended to be part of a comprehensive COPD management plan, which may include:
- Inhaled maintenance medicines (long-acting bronchodilators and/or inhaled corticosteroids where appropriate)
- Smoking cessation support
- Pulmonary rehabilitation
- Vaccinations and prevention of infections
Dosing Information (General Guidance)
Important: Always follow the exact dosing instructions provided by your clinician or pharmacist. The information below reflects typical patterns used for roflumilast therapy.
Typical adult dosing
- Initial: 250 µg once daily
- Maintenance: 500 µg once daily if tolerated
Special populations
- Low body weight: Some patients—especially those with significant weight loss or low body weight—may be at higher risk of unwanted weight changes and reduced tolerability.
- Liver impairment: Use may be restricted or require extra caution. Discuss liver health with your healthcare provider.
- Kidney impairment: Your clinician may review suitability and monitor response.
- Older adults: Dosing usually follows the standard approach, but side effects should be monitored carefully.
Safety Profile and Side Effects
Common side effects
Many side effects occur early in treatment, especially during titration. If they are mild, your clinician may advise continuing while monitoring.
- Nausea
- Diarrhoea
- Abdominal pain or discomfort
- Decreased appetite
- Headache
- Weight loss (can occur, sometimes significant)
- Insomnia or sleep disturbances in some people
Serious warnings (seek urgent medical help)
Contact a healthcare professional urgently if you experience:
- Severe diarrhoea, dehydration, or inability to keep fluids down
- Significant or unexplained weight loss
- New or worsening mood symptoms, including depression or suicidal thoughts
- Signs of liver problems (e.g., yellowing of the skin/eyes, dark urine, severe fatigue with other symptoms)
Mood and mental health considerations
Roflumilast may affect mood in some individuals. It is especially important to monitor yourself and seek help promptly if you:
- Have a history of depression
- Notice persistent low mood, anxiety, or behaviour changes
- Experience thoughts of self-harm
When to pause and call your healthcare provider
If side effects are bothersome—particularly gastrointestinal symptoms or weight loss—speak with your clinician or pharmacist. You may need dose adjustment or additional support.
Practical Use Tips (Getting the Best Results)
1) Track symptoms and weight
- Weigh yourself regularly if you are at risk of weight loss.
- Note changes in appetite, bowel habits, and breathlessness.
2) Manage early stomach effects
- Take with food if nausea or stomach discomfort occurs.
- Stay hydrated if diarrhoea occurs.
- If symptoms are severe, contact your healthcare provider promptly.
3) Keep using your COPD inhalers as planned
Daliresp supports long-term COPD control but does not replace rescue inhalers. Use your other COPD medicines exactly as directed.
4) Smoking cessation and lifestyle
Stopping smoking (or avoiding smoke exposure) can substantially improve COPD outcomes. Pulmonary rehabilitation, vaccinations, and infection prevention are also important.
5) Avoid missed doses
Once-daily dosing works best when taken at the same time each day. If you forget frequently, consider setting a reminder.
Alternative Options for COPD Exacerbation Prevention
Depending on your COPD severity, symptoms, lung function tests, and exacerbation history, your clinician may consider other options. Alternatives may include:
- Inhaled maintenance therapies (e.g., long-acting bronchodilators; inhaled corticosteroids in selected patients)
- Other add-on medicines used for exacerbation reduction in appropriate groups
- Non-drug strategies such as pulmonary rehabilitation, vaccination, and smoking cessation support
Your best alternative depends on your medical history, current medications, and how you respond to therapy. Discuss options with your healthcare provider.
