1) Basic product information

• Brand name: Daliresp
• Generic name: Roflumilast
• Medicine type: Phosphodiesterase-4 (PDE4) inhibitor
• Common strengths: Typically available as 250 micrograms and 500 micrograms tablets (follow the specific pack you receive).
• How it’s taken: Usually once daily by mouth
• Who it’s for: Adults with selected COPD features (see “Indications” below)

In the UK, Daliresp is regulated medicine and is supplied under the normal healthcare framework. Availability can vary by pharmacy and stock levels, especially for specific strengths or packaging.

2) What Daliresp does (mechanism of action)

Roflumilast works by targeting an enzyme called phosphodiesterase-4 (PDE4). PDE4 is involved in controlling inflammation in the airways. By inhibiting PDE4, roflumilast helps:

• Reduce airway inflammation linked to COPD flare-ups
• Help improve breathing-related symptoms over time in appropriate patients
• Lower the likelihood of exacerbations in people with severe disease and a history of flare-ups

Roflumilast is considered a maintenance treatment. It is not designed to provide rapid relief during sudden breathlessness.

3) How the body handles roflumilast (pharmacokinetics)

“Pharmacokinetics” describes how the medicine is absorbed, distributed, metabolised and eliminated. Understanding these points can help you appreciate why timing and consistent daily use matter.

If you have moderate to severe liver problems, dosing may be unsafe; your healthcare team should advise. Always follow the guidance provided with your specific prescription and pack.

4) Typical use in COPD

In the UK, Daliresp (roflumilast) is used to treat moderate to severe COPD in selected people. It may be recommended in particular when:

• You have severe COPD or advanced symptoms
• You have a history of exacerbations (flare-ups)
• Your COPD is not sufficiently controlled with inhaled therapies alone
• There is an inflammatory component suggested by your clinical profile (your clinician will decide based on the overall assessment)

Roflumilast is commonly used alongside inhaled medicines for COPD (for example, long-acting bronchodilators). It is intended as an add-on maintenance therapy.

5) Indications (who it’s for)

Daliresp is indicated for the reduction of exacerbations in patients with severe COPD associated with chronic bronchitis, with a history of exacerbations.

It is not indicated for asthma, and it is not intended as a rescue treatment for sudden episodes of breathlessness.

6) How to take Daliresp (dosing and timing)

Always follow the dose strength and instructions on your medicine label. Typical guidance for roflumilast is:

• Frequency: Usually once daily
• Starting dose: Some patients may start on a lower strength (e.g., 250 micrograms) to improve tolerability before moving to 500 micrograms, depending on local protocols and your clinician’s advice.
• Maintenance dose: Commonly 500 micrograms once daily for appropriate patients.

Best time of day

Choose a consistent time each day. Many people find it helpful to take the tablet at the same time daily. Because side effects like nausea, diarrhoea, and weight loss may occur, some patients prefer timing around meals—however see “Food interactions” for specifics.

If you miss a dose

If you forget a dose, take it when you remember on the same day. If it is almost time for your next dose, skip the missed dose and resume your regular schedule. Do not take a double dose to make up for a missed tablet.

Do not stop suddenly without advice

Stopping roflumilast may affect COPD control over time. If you are considering stopping due to side effects or concerns, discuss this promptly with a healthcare professional.

7) Food interactions and stomach effects

Food can influence how roflumilast behaves in the body. In many cases, taking roflumilast with or without food may be acceptable, but the timing relative to meals can affect absorption and tolerability.

• Some patients tolerate the medicine better when taken with food, particularly if they experience stomach upset.
• If your symptoms worsen when taken with a specific meal, try a consistent routine and discuss changes with a healthcare professional.

Follow the instructions on your pack and the advice you were given. If a pharmacist or prescriber gave a specific direction on food timing, that guidance should take priority.

8) Alcohol interactions

Moderate alcohol use is not known to have a direct “one-to-one” interaction with roflumilast in most patients, but alcohol can still be a factor because:

• Both alcohol and roflumilast may contribute to stomach irritation or nausea/diarrhoea in some people.
• Alcohol may worsen sleep quality and can affect mood. Mood-related side effects are relevant with roflumilast.

If you drink alcohol, consider keeping it moderate and stop drinking if you notice increased side effects. Seek advice if you develop persistent gastrointestinal symptoms, dehydration, or changes in mood.

9) Medicine interactions (important)

Drug interactions can change how roflumilast works or how strongly side effects occur. Below are common categories to consider. Always tell your healthcare professional or pharmacist about all medicines you take, including over-the-counter products and herbal supplements.

Key interaction themes

• Liver metabolism (CYP-related) interactions: Some medicines can increase or decrease roflumilast levels.
• Medicines that affect stomach or gut: May compound diarrhoea or nausea.
• Medicines affecting mood or sleep: Because mood-related side effects can occur with roflumilast.

Examples of medicines/categories to discuss

• CYP inducers (can reduce roflumilast exposure), such as certain seizure medicines or rifampicin (an antibiotic).
• Strong inhibitors (can increase roflumilast exposure), depending on your specific medicines.
• Other medicines associated with weight loss or gastrointestinal side effects (may increase risk or severity).
• Medicines used for depression or anxiety, if you have had mood changes before (not necessarily prohibited, but worth discussing).

This list is not exhaustive. Your pharmacist can check interactions using your medicine list and your exact tablet strength.

When to get urgent help

Contact a healthcare professional urgently if you develop severe rash, swelling, fainting, severe diarrhoea with dehydration, or signs of serious mood changes such as new/worsening suicidal thoughts.

10) Safety profile: side effects and who should be cautious

Like all medicines, Daliresp can cause side effects. Many people tolerate it, but some experience issues—especially early in treatment. Knowing what to expect can help you act quickly if symptoms become significant.

Common side effects

• Diarrhoea
• Nausea
• Decreased appetite and weight loss (important in COPD patients who are already at risk of being underweight)
• Headache
• Abdominal pain or discomfort
• Insomnia or sleep disturbance (may occur in some people)

Less common but important risks

• Mood changes: anxiety, depression, and in rare cases suicidal ideation have been reported. Seek medical help promptly if you notice worsening mood, agitation, or suicidal thoughts.
• Severe allergic reactions: swelling of face/lips, trouble breathing, or widespread rash require urgent assessment.
• Severe diarrhoea or dehydration, especially if you are frail or already have fluid/electrolyte issues.

Who should use extra caution

• Low body weight or history of significant unintended weight loss.
• History of depression or previous mood disorders—monitor for changes.
• Liver impairment: roflumilast may not be suitable for moderate to severe liver problems. Your clinician will assess.
• Chronic diarrhoea or conditions that predispose you to diarrhoea.

Practical monitoring tips

• Check your weight weekly at home if you can.
• Keep an eye on appetite changes and ongoing stomach symptoms.
• Monitor mood and sleep; tell your healthcare team early if you feel different.
• If diarrhoea occurs, drink fluids and consider whether you may need medical advice if it persists.

11) Practical use tips for everyday life

1. Take it consistently

Using a consistent daily routine can help reduce missed doses and support steadier exposure. A phone reminder or linking the tablet to a daily habit (e.g., breakfast/dinner) may help.

2. Protect your appetite and weight

Weight loss can occur. If you notice reduced appetite:

• Choose nutrient-dense foods and small frequent meals.
• Ask a dietitian or GP for advice if weight loss continues.
• Report significant weight changes early.

3. Manage diarrhoea and nausea safely

If you develop diarrhoea or nausea, focus on hydration. If symptoms are severe, persistent, or accompanied by weakness or dizziness, seek medical advice.

4. Mood and sleep awareness

Because mood changes can occur, it helps to involve family members or carers who can notice changes in you. If you experience anxiety, depressed mood, agitation, or sleep problems, contact your healthcare team promptly.

5. Keep your inhalers on track

Daliresp does not replace your inhalers. Continue using your existing COPD medicines as directed, and ensure you use them correctly.

12) Alternative treatment options

COPD management often involves a combination of inhaled therapies, lifestyle support, vaccines, pulmonary rehabilitation, smoking cessation and, in selected cases, oral medicines. Alternatives to roflumilast may include:

Inhaled long-term medicines (commonly used)

• Long-acting beta₂-agonists (LABAs)
• Long-acting muscarinic antagonists (LAMAs)
• Combination inhalers (LABA/LAMA, and in some cases LABA/ICS)

Other add-on oral options (for selected patients)

• Medicines used for exacerbation prevention depending on your phenotype and exacerbation history.

Your best alternative depends on your COPD severity, symptoms, exacerbation pattern, lung function tests, and your tolerance of medicines. Discuss options with a clinician or pharmacist.

If you cannot tolerate roflumilast due to side effects, do not stop suddenly without advice—your clinician may adjust your regimen.

13) UK market and legal/regulatory context

In the UK, medicines like Daliresp are authorised and monitored under the medicines regulatory system. Supply is controlled to ensure safe use, with prescribing and supply guided by clinical assessment. Pharmacies follow UK standards for authenticity checks, storage, and patient counselling.

Recommendations for COPD treatment are supported by UK clinical guidance and updates to standard care pathways. These commonly emphasise:

• Correct inhaler technique and adherence
• Smoking cessation and vaccination
• Individualised selection of add-on therapies for exacerbation risk
• Regular review of symptoms, inhaler use, and side-effect burden

Recent guidance (general)

UK COPD guidance continues to focus on risk reduction for exacerbations and on using therapies that match the patient’s COPD “phenotype” and exacerbation history. Oral anti-inflammatory/anti-exacerbation options such as roflumilast may be considered for appropriate patients with severe COPD and chronic bronchitis features, particularly where exacerbations persist despite inhaled treatments.

Always rely on the most current advice from your healthcare professional, as local policies and individual circumstances vary.

14) Delivery and availability in the United Kingdom

Online pharmacies in the UK may offer delivery to UK addresses. Availability depends on stock levels and the strength/formulation you need. To help ensure a smooth experience:

15) Frequently asked questions (FAQ)

Is Daliresp a reliever inhaler?

No. Daliresp (roflumilast) is a maintenance tablet used to help reduce exacerbations over time. It is not a fast-acting rescue medicine for sudden breathlessness. Keep your reliever inhaler as prescribed.

How long does it take to work?

Roflumilast is intended for long-term management. Some people may notice changes in symptoms gradually, but exacerbation prevention is typically assessed over weeks to months. Continue daily use as advised.

Can I take it with food?

Food may affect absorption and tolerability. Many patients are advised to follow the specific instructions provided with their medicine. If stomach side effects occur, consistent timing (often with food) may help—discuss with a pharmacist if you are unsure.

What should I do if I lose weight?

Report weight loss to your healthcare professional promptly. Weight loss can be a known side effect, and COPD patients may already be at nutritional risk.

Are mood changes possible?

Yes. Anxiety, depression, and other mood-related effects have been reported. If you notice new or worsening mood symptoms, contact your healthcare team urgently, especially if you feel unsafe or have suicidal thoughts.

Can I drink alcohol while taking Daliresp?

Moderate alcohol may be possible for some people, but it can worsen stomach upset or affect mood and sleep. If you experience side effects, reduce or avoid alcohol and seek advice if symptoms persist.

Will it interact with my other medicines?

It may. Interactions can occur with medicines that affect liver metabolism, as well as those that influence gastrointestinal function or mood. Always provide your full medicine list to your pharmacist for interaction checking.

What happens if I miss a dose?

Take it when you remember on the same day. If it’s near the time of your next dose, skip the missed dose. Do not double up.

Who should not take roflumilast?

Suitability depends on your individual health factors. Extra caution is needed for certain liver problems and for people at higher risk of mood changes or underweight. Your clinician will decide based on your medical history.

What are red-flag side effects?

Get urgent medical attention for signs of severe allergic reaction, severe diarrhoea with dehydration, or serious mood changes including suicidal thoughts.
