Dulera is a combination inhaler used for the long-term maintenance treatment of asthma in patients 5 years of age and older. It contains two active ingredients: mometasone furoate, an inhaled corticosteroid (ICS), and formoterol fumarate, a long-acting beta2-agonist (LABA).
Dulera is prescribed when asthma is not adequately controlled with an inhaled corticosteroid alone. It is not a rescue inhaler and should not be used to treat sudden breathing problems. Patients still need a separate short-acting rescue inhaler (such as Albuterol) for acute asthma attacks.
Dulera is manufactured by Organon (formerly part of Merck). There is currently no generic version available in the United States.

Dulera works through a dual mechanism of action that targets two key aspects of asthma:
By combining anti-inflammatory and bronchodilator effects in a single inhaler, Dulera provides more comprehensive asthma control than either component alone. Patients should shake the inhaler well before each use, take 2 puffs twice daily, and rinse their mouth with water afterward to reduce the risk of oral thrush.

Dulera earns a findability score of 55 out of 100, placing it in the moderate-difficulty range. As a brand-name combination inhaler with no generic equivalent currently available, Dulera can be harder to track down than more widely stocked asthma medications. An active shortage of the 100 mcg/5 mcg strength reported since September 2025 has further complicated availability at many retail pharmacies.
The lack of a generic option means patients are limited to the brand product manufactured by Organon. Insurance formularies often place Dulera on higher tiers or require step therapy through preferred alternatives like generic Symbicort or Advair first, which can add delays. If your pharmacy is out of stock, Medfinder can help you locate nearby pharmacies that currently have Dulera in stock.
Dulera is commonly prescribed by several types of healthcare providers:
Dulera is also available through telehealth consultations, which can be a convenient option for established asthma patients who need prescription renewals.
No, Dulera is not a controlled substance. It is not classified under any DEA schedule. You do not need special prescriptions or ID verification to fill it, though a valid prescription from a licensed healthcare provider is still required.
The most commonly reported side effects of Dulera include:
Important safety information: Dulera carries a boxed warning about the risk of asthma-related death associated with LABAs. It should only be used when asthma is not adequately controlled on an inhaled corticosteroid alone. Serious but less common side effects include adrenal insufficiency, paradoxical bronchospasm, reduced bone mineral density, glaucoma, cataracts, and growth suppression in children. Contact your doctor immediately if you experience worsening breathing, chest pain, or severe allergic reactions.

Strong CYP3A4 inhibitors
moderate(ketoconazole, ritonavir, clarithromycin, itraconazole) — can increase the systemic effects of mometasone, raising the risk of adrenal suppression and other corticosteroid side effects. Use with caution.
Beta-blockers
moderatemay block the bronchodilating effect of formoterol and can cause severe bronchospasm. Avoid use together when possible.
MAO inhibitors and tricyclic antidepressants
moderatemay increase the cardiovascular effects of formoterol, including elevated heart rate and blood pressure.
Non-potassium-sparing diuretics
moderatemay worsen low potassium levels (hypokalemia) and increase the risk of heart rhythm changes.
Other long-acting beta2-agonists
moderateshould not be used together with Dulera due to risk of overdose and cardiovascular side effects.
Dulera remains an effective option for managing moderate to persistent asthma, but finding it in 2026 can be a challenge. With no generic available, a cash price of $400 to $500, and an ongoing shortage of the 100 mcg/5 mcg strength, patients may need to do some legwork to fill their prescriptions.
If you have commercial insurance, the Organon Dulera Savings Card can reduce your copay to as little as $15 per prescription. Uninsured patients should explore the Organon Patient Assistance Program or consider switching to a more affordable generic alternative like Symbicort or Advair with their doctor's guidance.
