Nintedanib (Nintedanib) — Patient-Friendly Guide (Australia)

Nintedanib is an oral medicine used to treat certain serious lung conditions, and in some cases to slow the progression of disease. This page explains how nintedanib works, how it’s taken, what to expect, and key safety information for people living in Australia.

This information is designed to be clear and practical. It does not replace advice from your healthcare professional.

Quick Product Information

How Nintedanib Works (Mechanism of Action)

Nintedanib belongs to a class of medicines called tyrosine kinase inhibitors. It helps slow the processes that drive fibrosis (scarring and thickening of lung tissue).

Specifically, it targets multiple signalling pathways involved in:

• Fibroblast activation (cells that contribute to scarring)
• Abnormal tissue remodelling
• Pathological growth signalling in tissues
• Angiogenesis (formation of new blood vessels linked to disease progression)

In practical terms, nintedanib is intended to reduce the rate of decline in lung function for appropriate conditions, rather than providing immediate symptom relief.

Pharmacokinetics (Absorption, Distribution, Metabolism, Elimination)

Pharmacokinetics describes how the body processes a medicine. While exact figures vary by person, the key points for nintedanib are:

• Absorption: Nintedanib is absorbed after taking an oral dose. Swallow the capsule whole; do not crush or open.
• Time to reach peak level: Levels typically peak a few hours after ingestion (commonly about 2–4 hours, depending on the situation).
• Distribution: The medicine distributes into tissues; it has protein binding in blood.
• Metabolism: Nintedanib is primarily metabolised in the liver, mainly through the CYP3A4 pathway.
• Elimination: It is eliminated largely via faeces (bile-related routes), with a smaller portion in urine.
• Half-life: The effective duration in the body supports a twice-daily schedule (exact half-life may vary).

Because metabolism involves CYP3A4, medicines that strongly affect CYP3A4 can change nintedanib levels.

What Nintedanib Is Typically Used For in Australia

Nintedanib is used for fibrotic lung diseases where progressive scarring occurs. In Australia, indications align with local regulatory approvals and specialist treatment plans. Common clinical settings include:

• Idiopathic pulmonary fibrosis (IPF)
• Some other chronic fibrosing interstitial lung diseases (as defined in clinical guidance)
• Progressive fibrosing interstitial lung disease (PF-ILD) in appropriate patients

Your specialist will determine whether nintedanib is suitable based on your diagnosis, lung function tests, imaging, and overall health.

Typical Timing and How to Take It

For most people, nintedanib is taken twice daily (about 12 hours apart). A practical schedule might be:

• Morning: take your dose around the same time each day with your meal
• Evening: take the second dose about 12 hours later

Take with food: Nintedanib is usually recommended to be taken with food to reduce certain stomach-related side effects.

Swallow whole: Keep capsules intact. Do not crush, open, or chew.

If you miss a dose: If you remember soon after your scheduled time, you may take it—unless it’s close to the next dose. In general:

• Do not take double to make up for a missed dose.
• Follow the plan provided by your healthcare professional or dispensing information.

Food Interactions: What to Know

Food can affect stomach comfort and absorption. To support tolerability, nintedanib is typically recommended to be taken with food.

• Take with a meal (or a substantial snack if your instructions allow).
• Avoid sudden changes in meal patterns if they worsen symptoms such as nausea or diarrhoea.

There are no universal “forbidden foods,” but your own experience matters. Some people find that very fatty meals increase gastrointestinal discomfort, while others tolerate all meal types well.

Alcohol Interactions

Alcohol does not always have a direct “mechanism” interaction with nintedanib, but it may affect safety—especially in relation to the liver and overall gastrointestinal side effects.

• Liver safety: Nintedanib can sometimes cause elevations in liver enzymes. Alcohol may also stress the liver. Limit or avoid alcohol if you have raised liver function tests or symptoms of liver irritation.
• GI tolerance: Alcohol can worsen nausea, diarrhoea, reflux, and stomach upset in some people.

If you drink alcohol, discuss an appropriate approach with your treating team—particularly if you have liver disease, hepatitis, or abnormal blood test results.

Medicine Interactions (Important)

Because nintedanib is metabolised through CYP3A4, interactions can be significant. Tell your healthcare professional about all medicines and supplements you use, including:

• Prescription medicines
• Over-the-counter products
• Herbal supplements
• Vitamin and mineral products

Medicines that may increase nintedanib levels

Strong inhibitors of CYP3A4 may raise nintedanib concentrations, increasing the risk of side effects (such as diarrhoea, nausea, or liver enzyme increases).

Medicines that may reduce nintedanib levels

Strong CYP3A4 inducers may lower nintedanib levels, potentially reducing effectiveness.

Blood-thinning and bleeding risk

Nintedanib can increase bleeding risk in some patients. Caution is needed if you use:

• Anticoagulants (blood thinners)
• Antiplatelet medicines
• Other medicines that affect clotting

Other interaction considerations

• Liver-affecting medicines: medicines that also stress the liver may add risk.
• Gastrointestinal side effects: medicines causing diarrhoea or nausea may increase intolerance when combined with nintedanib.

Your prescribing team and pharmacist can check interaction risk using up-to-date Australian resources.

Dosing: Typical Regimens and Individual Adjustments

Dosing depends on the specific indication and your tolerability. In clinical practice in many settings, the standard regimen is:

• Common starting dose: often 150 mg twice daily (twice per day)
• Dose changes: if side effects occur, the prescriber may adjust the dose, interrupt treatment briefly, or reduce frequency to improve tolerability.

Important: Only follow the schedule provided with your supply and instructions from your healthcare professional. Do not change the dose on your own.

When dose adjustments are considered

• Persistent or severe diarrhoea
• Clinically significant liver enzyme elevations (based on blood tests)
• Other significant adverse reactions affecting daily life or safety
• Concomitant medicines that may increase nintedanib exposure

Safety Profile: Common and Serious Side Effects

Like all medicines, nintedanib can cause side effects. Many are manageable with early action, dose adjustments, and monitoring. Knowing what to watch for helps you stay in control.

Common side effects

• Diarrhoea (very common). Often begins early and can be managed with prompt treatment.
• Nausea
• Vomiting or abdominal discomfort
• Decreased appetite
• Weight loss (may occur if appetite is affected)
• Fatigue
• Elevated liver enzymes on blood tests
• Abdominal pain

Less common but important risks

• Bleeding events: especially in people also taking anticoagulants/antiplatelets or with certain medical conditions.
• High blood pressure or cardiovascular effects in some patients.
• Proteinuria (protein in urine) in some cases.
• Interstitial lung changes are a consideration in this treatment area—report breathing changes promptly.

Seek urgent medical help if you have

• Signs of severe bleeding (e.g., coughing/vomiting blood, black/tarry stools, unusual bruising with dizziness)
• Symptoms of liver problems: yellow skin/eyes (jaundice), dark urine, severe right upper abdominal pain, persistent severe nausea
• Severe or persistent diarrhoea causing dehydration (feeling faint, very dry mouth, reduced urination)
• Severe allergic-type reactions (swelling of face/lips, difficulty breathing, widespread rash)

Practical Use Tips (How to Improve Comfort and Adherence)

Many people discontinue nintedanib because side effects feel unexpected. The most effective approach is prevention and early management.

Diarrhoea prevention and treatment strategy (typical approach)

• Start early at the first sign of diarrhoea—don’t wait for it to become severe.
• Hydrate regularly (water and oral rehydration solutions if recommended).
• Use appropriate anti-diarrhoeal medicines as advised by your healthcare team. Common options include loperamide-based regimens in many clinical pathways.
• Monitor frequency: note how many times per day and whether there is blood or fever.
• Contact your doctor promptly if diarrhoea is persistent, severe, or leads to dehydration.

How to reduce nausea and stomach upset

• Take doses with food.
• Eat smaller meals if large meals worsen symptoms.
• Discuss anti-nausea strategies with your healthcare professional if needed.

Liver monitoring and check-ups

• Regular blood tests (often including liver enzymes) are commonly used to monitor safety.
• Attend scheduled appointments and report symptoms suggesting liver issues.

Bleeding risk awareness

• Inform clinicians before dental procedures or surgery.
• Report unusual bruising or bleeding.
• If you take blood thinners, ensure your clinician knows your exact regimen.

Swallowing and storage

• Swallow capsules whole with water.
• Keep in original packaging and store as directed on the label (typically at controlled room temperature).
• Keep out of reach of children.

Alternative Treatment Options

Treatment for fibrotic lung disease is individual. Depending on the exact diagnosis and stage, alternatives or additions may include:

• Other anti-fibrotic medicines (depending on eligibility and clinician judgement)
• Supportive care: pulmonary rehabilitation, vaccination, symptom management, oxygen if needed
• Managing underlying or associated conditions (e.g., autoimmune-associated interstitial lung diseases may require different approaches)
• Clinical trials for eligible patients

Your specialist can discuss how benefits and risks compare for your specific type of lung disease and your overall health.
