Breyna and Symbicort are prescription combination inhalers used to help manage asthma and chronic obstructive pulmonary disease (COPD). Breyna is the FDA-approved generic equivalent of Symbicort, meaning it contains the same active ingredients and is intended to work the same way.

In this article, we’ll review each medication individually—what it treats, how it works, how to use it, side effects, and precautions—before comparing the key differences between them.

What Is Breyna?

Breyna is a combination inhaler that contains two active ingredients:

• Budesonide, an inhaled corticosteroid (ICS) that helps reduce inflammation in the airways
• Formoterol fumarate, a long-acting bronchodilator (LABA) that helps open the airways

Breyna is the generic equivalent to Symbicort.

What Breyna Is Used For

Breyna is prescribed for:

• Asthma maintenance treatment (ages 6 and up)
• COPD maintenance treatment in adults
• Reducing flare-ups
• Improving long-term breathing control

It is not a rescue inhaler and should not be used for sudden breathing problems.

How Breyna Works

Breyna combines a steroid (to reduce airway inflammation) with a bronchodilator (to relax airway muscles).
Taken regularly, it helps reduce coughing, wheezing, chest tightness, and shortness of breath.

How to Take Breyna

Follow your healthcare provider’s instructions. Typical use includes:

• 2 puffs twice daily (morning and evening)
• Use the inhaler with correct technique
• Rinse mouth with water after each use and spit it out to prevent oral thrush

Your provider may adjust your dose based on symptoms and response.

Potential Side Effects of Breyna

Common side effects may include:

• Sore throat
• Hoarse voice
• Oral thrush
• Cough
• Headache
• Mild tremor
• Increased heart rate

More serious side effects are possible, especially with long-term steroid use. Contact your provider if you experience worsening breathing or severe reactions.

Precautions for Breyna

Tell your healthcare provider if you have:

• Heart conditions
• High blood pressure
• Osteoporosis
• Thyroid issues
• Immune system problems
• A history of oral thrush
• A need for frequent rescue inhaler use

What Is Symbicort?

Symbicort is the brand-name version of the budesonide/formoterol combination inhaler. It contains:

• Budesonide (inhaled corticosteroid)
• Formoterol fumarate (long-acting bronchodilator)

It has been used for many years as a standard treatment for asthma and COPD.

What Symbicort Is Used For

Symbicort is used for:

• Asthma maintenance treatment (ages 6 and up)
• COPD maintenance treatment (adults)
• Preventing asthma flare-ups
• Long-term symptom control

Symbicort is also not a rescue inhaler.

How Symbicort Works

Symbicort works identically to Breyna. The combination of steroid and bronchodilator reduces inflammation and opens the airways for easier breathing.

How to Take Symbicort

Typical dosing is:

• 2 puffs twice daily
• Use inhaler at the same times each day
• Rinse mouth after each use

Proper inhaler technique is important for effectiveness.

Potential Side Effects of Symbicort

Side effects may include:

• Sore throat
• Hoarseness
• Thrush
• Cough
• Increased heart rate
• Shakiness
• Headache

Side effects are generally similar to Breyna.

Precautions for Symbicort

Discuss with your healthcare provider if you have:

• Cardiovascular conditions
• Diabetes
• Thyroid problems
• Osteoporosis
• Frequent infections
• A need for frequent rescue inhaler use

While the medications are therapeutically equivalent, there are a few practical differences:

1. Cost

• Breyna: Typically lower cost as the generic
• Symbicort: Usually more expensive as the brand-name option

For many patients, this is the biggest distinction.

2. Insurance Coverage

• Many insurance plans encourage using generics like Breyna
• Some plans still prefer Symbicort or cover both differently

Coverage varies by pharmacy benefit plan.

3. Inhaler Device

Though similar, the inhalers may feel slightly different to use. Some patients prefer the brand’s device, while others notice no difference.

4. Availability

• Symbicort tends to be widely available
• Generic availability can vary between pharmacies

5. Patient Preference

Some people stay with Symbicort because they are used to it, while others switch to Breyna to save money without sacrificing effectiveness.

If your provider writes a prescription that can be filled at a retail pharmacy, you may be able to use a CareCard prescription discount card to look for savings. Because Breyna is a generic, it is often more affordable even before discounts are applied.

Ask your provider for a written prescription and present your CareCard prescription discount card at the pharmacy counter to compare pricing.

Breyna and Symbicort contain the same active ingredients and work the same way to manage asthma and COPD. Breyna is the generic version and is typically more affordable, while Symbicort is the brand name that some patients and providers are accustomed to using.

Your healthcare provider can help determine which inhaler is the best fit based on your symptoms, insurance coverage, and treatment goals.

Is Breyna the same as Symbicort?
Yes. Breyna contains the same active ingredients as Symbicort and is considered its FDA-approved generic equivalent.

Is Breyna as effective as Symbicort?
Yes. Breyna is designed to provide the same therapeutic benefits as Symbicort.

What is the main difference between them?
The main difference is cost—Breyna is typically cheaper because it is a generic.

Can I switch from Symbicort to Breyna?
Many people can switch with no issue, but you should talk to your healthcare provider before changing inhalers.

Do they have the same side effects?
Yes. Because they contain the same active ingredients, their side effect profiles are nearly identical.
