“Doctor, my friend has lung fibrosis and is taking steroids, but you’ve prescribed antifibrotic medicine for me. Why are our treatments different?”
This is one of the most common questions patients ask after being diagnosed with interstitial lung disease (ILD).
Many people believe that steroids are the strongest treatment for every lung disease, while others assume that antifibrotic medicines can cure lung fibrosis.
The truth is that these medicines work in very different ways, and choosing the right treatment depends on the type of interstitial lung disease you have, not simply on how severe it is.
Understanding the difference between antifibrotic medicines and steroids in ILD can help you feel more confident about your treatment and why your pulmonologist has recommended it.
What Is Interstitial Lung Disease (ILD)?
Interstitial lung disease (ILD) is a group of conditions that cause inflammation, scarring (fibrosis), or both within the lungs.
Some ILDs are mainly inflammatory, while others are predominantly fibrotic. This distinction is important because it influences which medicines are most likely to help.
Your pulmonologist will recommend treatment based on the underlying disease rather than using the same medication for every patient.
Why Aren’t All ILD Patients Treated the Same Way?
Although many ILDs cause breathlessness and cough, they do not all behave in the same way.
Some conditions are driven mainly by inflammation, which may respond well to steroids or other immunosuppressive medicines.
Others are driven mainly by fibrosis (lung scarring). In these diseases, antifibrotic medicines are often more appropriate because they are designed to slow the progression of scarring.
This is why two patients with different types of ILD may receive completely different treatments.
What Are Antifibrotic Medicines?
Antifibrotic medicines are drugs that help slow the progression of lung scarring.
They do not remove existing scar tissue or cure lung fibrosis, but they can reduce the rate at which fibrosis worsens in eligible patients.
The two antifibrotic medicines most commonly used are:
- Pirfenidone
- Nintedanib
These medicines are commonly prescribed for Idiopathic Pulmonary Fibrosis (IPF) and, in selected cases, for other progressive fibrosing interstitial lung diseases, depending on the clinical situation and current treatment recommendations.
What Do Antifibrotic Medicines Do?
Their main goal is to:
- Slow the progression of lung fibrosis.
- Help preserve lung function for longer.
- Reduce the rate of decline seen on pulmonary function tests.
- Delay worsening of symptoms in many patients.
It is important to understand that antifibrotic medicines are designed to slow disease progression, not to reverse existing scarring.
What Is the Role of Steroids in ILD?
Steroids, such as prednisolone, work differently.
Rather than targeting fibrosis, they reduce inflammation within the lungs.
For this reason, steroids may be helpful in certain inflammatory interstitial lung diseases, including selected autoimmune-related ILDs, hypersensitivity pneumonitis, organizing pneumonia, eosinophilic lung diseases, and other conditions where inflammation is a major feature.
However, steroids are not appropriate for every patient with ILD, and in some conditions—particularly Idiopathic Pulmonary Fibrosis (IPF)—routine long-term steroid therapy is generally not recommended because it has not been shown to improve outcomes and may increase the risk of adverse effects.
Why Has My Doctor Chosen Antifibrotic Medicine Instead of Steroids?
Many patients assume that steroids are a stronger medicine.
In reality, your treatment is chosen based on how your disease behaves, not on which medicine is “stronger.”
If your ILD is mainly causing progressive fibrosis, an antifibrotic medicine may provide greater benefit.
If inflammation is the main problem, steroids or other anti-inflammatory medicines may be more appropriate.
Sometimes, different medicines are used at different stages of the disease or in combination, depending on the diagnosis and your overall health.
Can Antifibrotic Medicines and Steroids Be Used Together?
In some patients, yes.
Whether these medicines are used together depends entirely on the specific type of ILD, the amount of inflammation present, and the overall treatment plan developed by your pulmonologist.
Not every patient will require both medicines, and treatment decisions should always be individualized.
Will These Medicines Cure My Lung Fibrosis?
This is another common concern.
Unfortunately, no current medication can completely reverse established lung fibrosis.
However, modern treatments can:
- Slow disease progression.
- Preserve lung function.
- Improve symptom control.
- Reduce complications in selected patients.
- Help maintain quality of life.
Early diagnosis and timely treatment often provide the greatest opportunity to achieve these goals.
What Else Is Important Besides Medication?
Successful interstitial lung disease treatment involves much more than taking medicines.
Your care may also include:
- Pulmonary rehabilitation.
- Regular pulmonary function tests.
- Oxygen therapy if required.
- Vaccinations.
- Smoking cessation.
- Nutritional support.
- Physical activity within your limits.
- Routine follow-up with your pulmonologist.
Together, these measures help support your overall lung health.
Common Questions Patients Ask
Can antifibrotic medicines repair damaged lungs?
No. They are designed to slow further scarring, not remove existing fibrosis.
Are steroids always better than antifibrotic medicines?
No. They treat different processes. The best treatment depends on the type of ILD you have.
Why does another patient with ILD have different treatment?
Because interstitial lung disease includes many different conditions, each requiring an individualized treatment plan.
Will I need these medicines for life?
Some patients require long-term treatment, while others may have changes in their treatment plan depending on disease progression, response to therapy, and the underlying diagnosis.
Can lifestyle changes help?
Yes. Staying active, avoiding smoking, maintaining vaccinations, attending follow-up appointments, and participating in pulmonary rehabilitation can all play an important role in your long-term care.
When Should You Speak to Your Pulmonologist?
Arrange a review if you notice:
- Increasing breathlessness.
- Worsening cough.
- Reduced exercise tolerance.
- New oxygen requirements.
- Side effects from medication.
- Questions about your treatment plan.
Never stop antifibrotic medicines or steroids without discussing them with your healthcare provider.
The Bottom Line
Antifibrotic medicines and steroids are not competing treatments—they have different roles in managing interstitial lung disease.
Antifibrotic medicines are used to slow the progression of lung scarring in appropriate patients, while steroids help reduce inflammation in selected inflammatory lung diseases.
The best treatment depends on your specific diagnosis, imaging, lung function, and overall clinical assessment. Understanding why a particular medicine has been recommended can help you take an active role in your care and improve long-term treatment adherence.
