Nintedanib Medications

Nintedanib Info

What is Nintedanib?

Nintedanib is a medication that belongs to a class of drugs known as tyrosine-kinase inhibitors. Its main purpose is to slow the formation of scar tissue in the lungs. This active ingredient appears in medicines such as Ofev and generic-named Nintedanib.

Medications with Nintedanib

In Hong Kong, the most common products that contain Nintedanib are:

• Ofev - the branded version, supplied as hard-gel capsules.
• Nintedanib - the generic form, also available as hard-gel capsules.

Both formulations come in the same strength and are taken by mouth. The capsules are usually prescribed by specialists in respiratory or rheumatology clinics. Availability may vary between public hospitals and private pharmacies, but both are approved by the Hong Kong Pharmacy and Poisons Board.

What Does Nintedanib Treat?

• Idiopathic Pulmonary Fibrosis (IPF) - a chronic disease where lung tissue becomes stiff, making breathing difficult. Nintedanib helps to slow the decline in lung function.
• Progressive Fibrosing Interstitial Lung Disease (PF-ILD) - a group of conditions where lung scarring worsens over time, irrespective of the underlying cause.
• Systemic Sclerosis-Associated Interstitial Lung Disease (SSc-ILD) - lung involvement linked to systemic sclerosis, an autoimmune condition that can cause skin thickening and organ fibrosis.

These uses are approved by health authorities in Hong Kong. The drug is intended for adults whose disease is progressing despite standard care. It is not a cure, but it can help maintain ability to perform everyday activities for a longer period.

How Nintedanib Works

Nintedanib blocks several signalling pathways that drive the growth of fibrotic tissue. By inhibiting these pathways, the medication reduces the speed at which new scar tissue forms in the lungs. The effect is usually seen within weeks, although the full benefit develops over several months of regular use.

Safety Information

Common Side Effects

• Loose stools or diarrhoea, often mild to moderate.
• Nausea and occasional loss of appetite.
• Stomach discomfort or abdominal pain.
• Mild increase in liver enzymes, which doctors monitor with blood tests.

These reactions are generally temporary and may improve with supportive care such as hydration and diet adjustments.

Serious Reactions

• Severe liver injury, indicated by yellowing of the skin or eyes, dark urine, or persistent nausea.
• Significant gastrointestinal bleeding, which may appear as black, tarry stools or vomiting blood.
• Rapid breathing difficulty or new-onset chest pain.

If any of these signs occur, seek emergency medical help right away.

Who Should Be Cautious

• People with pre-existing liver disease or abnormal liver test results.
• Individuals who are pregnant, planning pregnancy, or breastfeeding, as the drug may affect fetal development.
• Patients with a known hypersensitivity to Nintedanib or any of its capsule ingredients.

Interaction Awareness

• Strong inhibitors of the enzyme CYP3A4 (such as certain antifungal or antiviral medicines) can raise Nintedanib levels in the body.
• Blood-thinning agents (e.g., warfarin) may increase the risk of bleeding when taken together.
• Alcohol can aggravate liver-related side effects, so limiting intake is advisable.
• Because Nintedanib may cause mild dizziness, avoid driving or operating heavy machinery if you feel unsteady.

What to Know Before Using

Store the capsules in a cool, dry place away from direct sunlight and out of reach of children. Keep the original packaging until the expiry date is reached. Treatment duration differs according to the condition being managed-some patients use the drug for many years, while others may stop after a defined period. Always follow the instructions printed on the medication label and discussed with your healthcare team. For detailed usage, dosing, and administration, refer to your specific medication’s information.
