SMA Injection Cost – Why It Is the Costliest Injection in the World?

Zolgensma is recognized as the most expensive single-dose injection in the world, designed to treat Spinal Muscular Atrophy (SMA), a rare and severe genetic disorder affecting infants and children. This gene therapy treatment can be life-changing, addressing the root cause of SMA by replacing the defective SMN1 gene, thereby helping motor neurons function properly and preventing further muscle degeneration.

In India, the cost of a single Zolgensma injection can reach up to ₹17 crore, making it a significant financial challenge for families. The high price is due to the advanced technology, research, and gene therapy production costs involved in developing this treatment. SMA treatment costs can also vary depending on the type of SMA—for instance, Type 1 SMA typically requires earlier intervention, making timely treatment crucial.

Other SMA treatment options include Spinraza (nusinersen) and Evrysdi (risdiplam), which are comparatively less expensive but require multiple doses or continuous administration. Globally, the cost of SMA treatments can differ widely based on healthcare systems, availability, and subsidies.

What is Spinal Muscular Atrophy (SMA)?

Spinal Muscular Atrophy (SMA) is a rare genetic disorder that affects the motor neurons in the spinal cord, which control voluntary muscle movements like crawling, walking, breathing, and swallowing. In SMA, these nerve cells gradually weaken and die, causing progressive muscle wasting, loss of mobility, and respiratory difficulties. The severity varies, but Type 1 SMA is the most serious and can be fatal within the first few years of life without treatment.

The condition is caused by a mutation in the SMN1 gene, responsible for producing the Survival Motor Neuron (SMN) protein. Without adequate SMN protein, nerve cells cannot properly signal muscles, resulting in muscle weakness, particularly in proximal muscles such as shoulders, hips, and thighs.

Types of SMA 

There are five main types of spinal muscular atrophy, categorized by the age of onset, severity of symptoms, and expected lifespan. Each type can influence the SMA medicine cost, treatment options, and urgency of intervention:

SMA Type 0 (Congenital SMA):

It is a rare and most severe form that affects fetuses before birth. Infants born with type 0 have extremely limited movement and usually don’t survive beyond the first month. There is often no time for intervention, including access to spinal muscular atrophy injections.

SMA Type 1 (Severe SMA / Werdnig-Hoffmann Disease):

This is the most common form, accounting for about 60% of SMA cases. Symptoms typically begin before 6 months of age and include hypotonia, poor head control, and difficulty swallowing or breathing. Without treatment like Zolgensma injection, life expectancy is often under 2 years. The SMA type 1 injection price is extremely high, with the Zolgensma cost in India reaching nearly ₹17 crore per injection, making it the most expensive injection in India and among the costliest injections in the world.

SMA Type 2 (Intermediate SMA / Dubowitz Disease):

Symptoms of SMA Type 2 appear between 6 and 18 months. Children may be able to sit unaided, but often cannot walk. Respiratory issues are common. The SMA type 2 treatment cost in India varies, depending on the therapy chosen, but it can still be in the crores, especially if Zolgensma is considered. SMA Type 2 life expectancy is approximately 25 years.

SMA Type 3 (Mild / Kugelberg-Welander Disease):

Symptoms of this form arise after 18 months, usually in childhood or adolescence. Patients often walk initially but may lose mobility over time. While less severe, the spinal muscular atrophy medicine cost can still be significant, especially for long-term treatments like Spinraza or Evrysdi.

SMA Type 4 (Adult-Onset SMA):

This form typically develops after the age of 21 and progresses slowly. It usually does not affect life expectancy, and treatment costs are lower compared to earlier-onset types, though SMA injection costs still apply if ongoing therapies are used.

How Common is SMA?

Though considered rare, SMA is the second most common severe hereditary disease in infants and young children, after cystic fibrosis. It affects an estimated 1 in 6,000 to 1 in 11,000 live births. It is more prevalent among White and Asian populations compared to Black and Hispanic individuals.

Despite its rarity, the high costs associated with SMA disease treatment in India and worldwide have brought global attention to its economic and emotional burden. As we explore further, you’ll learn how the Zolgensma injection price in India, the most expensive injection in the world, shapes the future for SMA patients and their families.

What is Zolgensma, and Why Does it Matter?

Zolgensma is a revolutionary gene therapy designed to treat Spinal Muscular Atrophy (SMA), especially the most severe form, SMA Type 1. Approved by the FDA in 2019 and later in several other countries, including India, it has been hailed as a one-time treatment that can dramatically improve the quality of life and survival of SMA patients. But it’s also made headlines for another reason: its jaw-dropping price.

The Zolgensma injection price has been widely discussed because it’s considered the most expensive injection in the world. The average Zolgensma cost globally is around $2.1 million (₹17 crore in India) for a single injection dose. That means the Zolgensma injection price in India ranks it among the costliest injections in the world.

How Zolgensma Works

Zolgensma works by delivering a fully functional copy of the SMN1 gene (which is missing or faulty in SMA patients) through a specially engineered virus called AAV9. Unlike traditional drugs that need to be taken repeatedly, Zolgensma is a one-time intravenous injection. Once administered, it targets the motor neurons and helps the body produce the essential SMN protein, which can stop the progression of muscle degeneration.

This is why Zolgensma matters, it doesn’t just manage symptoms; it tackles the genetic root of the disease. For infants diagnosed with SMA Type 1, receiving Zolgensma early can mean the difference between being able to breathe and move independently or being dependent on ventilators and losing motor function.

Zolgensma’s Role in SMA Treatment

Despite its cost, Zolgensma has become a beacon of hope for families dealing with SMA type 1 and even some type 2 cases. It offers a chance at a nearly normal life for children who might otherwise face rapid disease progression. However, with the Zolgensma injection price in India being so high, the SMA injection cost becomes a life-or-death matter for many families.

Spinal Muscular Atrophy Treatment Options

Treating Spinal Muscular Atrophy (SMA) involves managing symptoms, slowing disease progression, and, where possible, correcting the genetic issue at its root. Over the years, several treatments have been approved that target the underlying cause of SMA, offering patients better chances at improved motor function and longer life expectancy. The main treatment options today include Zolgensma, Spinraza, and Evrysdi.

Each treatment has a different mechanism, mode of delivery, and dosing regimen. Let’s explore how these therapies compare, especially in the context of SMA injection, gene therapy, and daily management medications.

Comparing SMA Treatment Options

	Zolgensma	Spinraza	Evrysdi
Description	Gene therapy that adds a working SMN 1 gene into the patient	This injection is used to help make more SMN protein	Daily medicine to help make more SMN protein

Zolgensma

Zolgensma is the only treatment that delivers a working copy of the SMN1 gene, directly addressing the root cause of SMA. It’s a one-time intravenous injection, usually administered in children under 2 years of age. This therapy has transformed SMA treatment by potentially halting the disease’s progression early. As it reaches systemically through the bloodstream, it offers wide-reaching therapeutic benefits to motor neurons.

This treatment has garnered global attention not only for its medical impact but also for being labeled as the most expensive injection in the world.

Spinraza

Approved in 2016, Spinraza was the first major treatment breakthrough for SMA. It’s an antisense oligonucleotide that modifies the splicing of the SMN2 gene to produce more SMN protein. However, Spinraza must be administered through a spinal injection (intrathecal bolus). After four initial doses over two months, patients must continue receiving an injection every four months for life.

This makes Spinraza a long-term commitment, both in terms of administration and cost. It’s typically used in patients of all ages and across SMA types, including SMA Type 1, Type 2, and Type 3.

Evrysdi

Evrysdi, approved in 2020 (and updated in 2022 and 2025), is the first oral SMA medicine. Like Spinraza, it enhances SMN2 gene splicing to increase SMN protein production. It is approved for patients of all ages, and its daily dosing can be done at home, either orally or via a feeding tube.

While it offers ease of use, the daily regimen means lifelong medication, and the treatment must be consistently managed to maintain effectiveness. It’s a suitable option, especially where gene therapy is unavailable or unaffordable.

Which SMA Treatment Is Right for Whom?

The choice of treatment depends on multiple factors:

• Age of diagnosis

• SMA Type (1, 2, or 3)

• Severity and progression

• Access and affordability

• Medical eligibility for gene therapy (Zolgensma)

For infants diagnosed early with SMA Type 1, Zolgensma is often the first-line recommendation due to its one-time curative potential. However, as it is the costliest injection in the world, many families in India and around the world opt for Spinraza or Evrysdi, which are more accessible but require long-term use.

The Role of Timeliness in Treatment

The earlier SMA is diagnosed, the better the outcome, especially when considering the effectiveness of gene therapy like Zolgensma. For presymptomatic infants or those with SMA Type 1, timely intervention can mean the difference between permanent disability and achieving motor milestones.

However, the challenge remains in affording treatment, especially in regions like India, where the Zolgensma price in India or the SMA disease treatment cost in India is often unaffordable without crowdfunding or external support.

Zolgensma SMA Injection Cost Worldwide 

Zolgensma has been a game-changer in the treatment of Spinal Muscular Atrophy (SMA), especially for children diagnosed with SMA Type 1. Approved as a one-time gene therapy, it has made headlines not just for its life-saving potential but also for being the most expensive injection in the world. The SMA injection cost varies widely depending on the country, healthcare system, and availability of subsidies or insurance coverage.

Here is a look at the estimated Zolgensma SMA injection cost in different countries:

Country / Region	Approximate Zolgensma SMA Injection Cost (the figures are approximate values)
India	₹16 -18 crores
United States	$ 2.1 million (₹17.7 crores)
United Kingdom	€ 1.79 million (₹18 crores)
Japan	¥ 167 million (₹12 crores)
Germany	€ 1.9 million (₹18 crores)
Italy	€ 2.155 million (₹21 crores)
France	€ 1.9 million (₹18 crores)

While the Zolgensma injection price in India is one of the highest due to import logistics, developed countries often reduce the Zolgensma cost through state-funded programs, special reimbursements, or negotiated pharma deals.

Despite regional pricing variations, Zolgensma remains the costliest SMA medicine globally and continues to raise questions about affordability, access, and equity.

Zolgensma Injection Price in India

Since Zolgensma is not manufactured domestically, it has to be imported on a named-patient basis. This means families must request the drug through government approvals and pharmaceutical assistance programs. The cost includes:

• The base Zolgensma medicine price in USD,

• Import duties,

• GST and handling charges,

• Hospital administration charges.

The overall SMA injection cost in India is, therefore, significantly higher than in countries where the drug is directly marketed and supported by public health insurance.

Where Is Zolgensma Available in India?

Zolgensma is not available over the counter. It is administered only through specialized pediatric hospitals with:

• Advanced ICU support,

• Genetic diagnosis capability,

• Trained staff for intravenous gene therapy.

Hospitals in major cities like Mumbai, Delhi, Hyderabad, Bangalore, and Chennai have facilitated Zolgensma infusions for SMA Type 1 patients.

Alternatives to Zolgensma and Their Costs

While Zolgensma remains the only one-time SMA gene therapy, it isn’t the only hope for families battling spinal muscular atrophy. Many patients rely on alternatives like Spinraza® and Evrysdi, especially in countries like India, where the Zolgensma injection price is exceptionally high.

Comparing Alternatives by Cost and Approach

Spinraza is administered every four months for life, with a high annual cost. Though each dose is cheaper than Zolgensma, long-term use often surpasses ₹10 crore.

Evrysdi offers the ease of daily oral administration and is slightly more affordable annually, but it, too, is a lifetime treatment.

In contrast, Zolgensma, despite being the costliest injection in the world, is a single-dose therapy that eliminates ongoing hospital visits or repeated dosing.

Financial Trade-offs

Treatment	Nature of Therapy	Approximate Cost in India	Commitment
Zolgensma	One-time gene therapy	₹ 17-18 crores	No further doses
Spinraza	Repeat intrathecal doses	₹ 4-6 crore per year	Lifetime
Evrysdi	Daily oral dose	₹ 2.5-3 crore per year	Lifetime

Choosing Wisely

For many families, choosing between these options is not just medical, it’s financial. While the Zolgensma injection cost is undeniably high, it may prove more economical in the long run than years of SMA disease treatment costs via Spinraza or Evrysdi.

For families unable to access Zolgensma, these alternatives offer continued hope, especially when supported through government aid, insurance, or crowdfunding.

Is the Zolgensma Price Justified?

The Zolgensma injection price, often referred to as the ₹17 crore injection, has made headlines worldwide. Many wonder: Can any medicine truly be worth that much? While it may seem unimaginable, understanding why Zolgensma is so expensive requires looking beyond just the numbers.

One-Time, Life-Changing Therapy

Unlike traditional treatments for Spinal Muscular Atrophy (SMA), such as Spinraza or Evrysdi, which require lifelong use, Zolgensma is a single-dose gene therapy. It works by replacing the faulty SMN1 gene, which is the root cause of SMA. The one-time nature means:

• No ongoing hospital visits

• No repeated drug administration

• No accumulating annual costs

Over a lifetime, other SMA medicine costs can easily surpass ₹15–₹20 crore, making Zolgensma a potentially more cost-effective solution in the long term.

Gene therapies like Zolgensma are expensive because:

• High Development and Manufacturing Costs
• They involve cutting-edge genetic engineering
• Manufacturing is complex and highly regulated
• The patient base is very small, making it an orphan drug
• Years of research, trials, and FDA/EMA approvals cost billions

All of this contributes to Zolgensma’s cost being one of the highest among global injections, making it widely known as the most expensive injection in the world.

Global Pricing vs India

In the US, the Zolgensma price is approximately $2.1 million (₹17–₹18 crore). The Zolgensma injection price in India remains the same or slightly higher due to:

• Import duties

• Lack of domestic availability

• Custom taxes and logistics costs

When compared to long-term SMA disease treatment costs in India, especially for SMA type 1 or SMA type 2, this single-dose injection, although expensive, can reduce years of hospitalizations, therapy, and indirect medical expenses.

 Emotional and Quality of Life Value

For many families, Zolgensma is not just a medicine; it’s hope. It allows children to breathe, eat, sit, and even walk, milestones once thought impossible. That emotional value is hard to quantify.

So, is the Zolgensma injection price justified? From a clinical, economic, and emotional standpoint, yes, it often is. While it may be the most expensive injection in India and globally, its potential to transform a child’s life in one dose makes it more than just a drug, it’s a lifeline.

Crowdfunding and Financial Help for Zolgensma

The Zolgensma injection price, often exceeding ₹17 crore in India, makes it the costliest injection in the world. For most families, this astronomical figure is impossible to manage without external support. Fortunately, crowdfunding has emerged as a lifeline, especially for parents of children diagnosed with SMA type 1 or SMA type 2, who need urgent access to this life-saving gene therapy. 

Given the incredibly high SMA disease injection cost in India, most families rely on:

• Crowdfunding from donation platforms,

• Government initiatives like the “Integrated Child Development Services” (ICDS),

• CSR donations,

• NGO or pharma-sponsored access programs.

Why Crowdfunding Works

Crowdfunding platforms allow families to raise small donations from thousands of people online. These campaigns share the child’s story and medical urgency across social media, communities, and beyond, giving strangers a chance to contribute to a life-changing cause.

Many successful Zolgensma fundraising campaigns in India have helped babies receive treatment in time, overcoming the hurdles of SMA injection cost and Zolgensma injection price in India.
