Dulera® Inhaler for Asthma

Dulera® is a prescription inhaler for long-term asthma control. This page explains how it works, who it may suit, and how to access Canadian supply with US shipping from Canada, including typical options if considering the Dulera price without insurance. You can review strengths, storage, and safety basics so you can prepare for a conversation with your prescriber.

What Dulera Is and How It Works

Dulera combines two medicines: mometasone, an inhaled corticosteroid, and formoterol, a long-acting beta2-agonist. Together, they help reduce airway inflammation and keep bronchial muscles relaxed. This dual action may lower the frequency of daily symptoms and improve breathing over time. A mometasone formoterol HFA inhaler delivers measured puffs directly to the lungs for maintenance control, not quick relief.

Use a rescue inhaler for sudden symptoms. This treatment should be taken every day as directed, even when you feel well. You can learn more about asthma basics in our resource What Is Asthma, and see related topics under Asthma.

Who It’s For

This therapy is used for the maintenance treatment of asthma in adults and adolescents when a controller plus long-acting bronchodilator is appropriate. It is not for relief of sudden breathing problems. People with severe milk protein allergy, status asthmaticus, or acute, rapidly deteriorating asthma should avoid this medicine. Those with heart rhythm problems, high blood pressure, osteoporosis, glaucoma, cataracts, thyroid disorders, or infections should discuss risks with a clinician before starting.

If symptoms are not controlled, or if frequent reliever use continues, contact your healthcare professional. For broader breathing health tips, see our article Healthy Lung Month.

Dosage and Usage

Typical schedules involve two inhalations twice daily, about 12 hours apart. Your prescriber will select a strength based on previous controller therapy and current control. Do not use this medicine for acute symptom relief. Always have a fast-acting rescue inhaler available.

Prime the device before first use, and reprime if it has not been used for several days. Breathe out fully away from the inhaler, seal lips around the mouthpiece, and inhale slowly and deeply while pressing down on the canister. Hold your breath briefly, then exhale gently. Wait about a minute before the second inhalation. Rinse your mouth with water and spit after each dose to help reduce the risk of thrush. Tracking the dose counter helps avoid running out unexpectedly. For more device tips across this class, browse Respiratory.

Strengths and Forms

The inhaler is supplied in metered-dose canisters with 120 labeled puffs. Common strengths combine mometasone and formoterol in these options: 100 mcg/5 mcg and 200 mcg/5 mcg per actuation. Availability can vary by market and stock. Your prescriber will match the strength with your asthma severity and prior inhaled corticosteroid exposure. Many patients find the built-in counter and compact design convenient for daily use and travel. Some packs are labeled as Dulera inhaler 120 actuations, which indicates the total sprays in the canister.

Missed Dose and Timing

If you miss a dose, take it when you remember. If it is close to the next scheduled time, skip the missed dose and resume your regular schedule. Do not take extra puffs to make up for a missed dose. Keeping doses at the same times each morning and evening may help with consistency. If you repeatedly forget doses, ask your clinician about reminders or planning tools.

Storage and Travel Basics

Store the canister at room temperature and keep it capped when not in use. Avoid heat, flame, and direct sunlight. Do not freeze or puncture the canister. Keep out of reach of children and pets. For trips, carry your inhaler in hand luggage with your prescription label and a spacer if used. Avoid leaving it in a parked car. If traveling across time zones, keep morning and evening spacing consistent using local time. As a general safeguard, we support temperature-controlled handling when required.

Benefits

Inhaled corticosteroid and long-acting bronchodilator therapy can help reduce day-to-day symptoms and nighttime awakenings. Many people need fewer rescue puffs when adherent to a twice-daily controller. The device is portable, has a dose counter, and can be used with a spacer if a clinician recommends one. Rinsing the mouth after use helps minimize local side effects and supports long-term comfort with the regimen.

Side Effects and Safety

Common effects may include throat irritation, hoarseness, cough, headache, or mild tremor. Some people notice palpitations, nervousness, or muscle cramps. Oral thrush can occur; mouth rinsing after each dose helps reduce this risk.

• Throat discomfort or hoarseness
• Cough or upper respiratory symptoms
• Headache or dizziness
• Mild tremor or palpitations
• Oral thrush risk without rinsing

Serious risks are uncommon but can include paradoxical bronchospasm, severe allergic reactions, effects on adrenal function, changes in vision from glaucoma or cataracts, bone effects, and heart rhythm changes. Contact a healthcare professional if breathing suddenly worsens after dosing. Using this medicine with insulin or sulfonylureas is not typical; however, any therapy that can lower potassium or affect heart rhythm requires caution.

Drug Interactions and Cautions

Tell your prescriber about all medicines and supplements you take. Strong CYP3A4 inhibitors such as ketoconazole, clarithromycin, or ritonavir may increase steroid exposure. Beta-blockers can reduce the bronchodilator effect. Diuretics and xanthines may affect potassium levels. Other long-acting bronchodilators, MAOIs, or tricyclic antidepressants require caution due to cardiovascular effects. People with glaucoma, cataracts, osteoporosis, seizures, thyroid disorders, diabetes, or heart disease should review risks and monitoring. Learn about related respiratory regimens in Treatment And Medications.

What to Expect Over Time

With consistent use, many people notice steadier symptom control and fewer flare-ups. Relief is not immediate; a reliever inhaler is still needed for sudden symptoms. Regular follow-up helps your prescriber adjust the plan as control changes. Keeping a symptom diary, noting reliever use, and checking the dose counter can support steady control. If nighttime symptoms persist or exercise limitations continue, ask your clinician about reassessment and potential step-up or step-down strategies based on the official label.

Compare With Alternatives

Several controller options exist. Some combine an inhaled steroid with a long-acting bronchodilator in different devices. Two commonly prescribed alternatives include Advair® Hfa Inhaler and Breo® Ellipta. Device preference, dosing schedule, prior response, and insurer requirements may guide selection. Your prescriber can help determine whether this treatment or another controller fits your history and current needs.

Availability and Substitutions

Stock can fluctuate. If a canister is unavailable, a prescriber may recommend a comparable controller from the same class. Our team can share in-stock options that match your prescription. You can also explore a Dulera online pharmacy listing for current availability and alternatives. Any switches should follow clinician guidance and the official product information.

Patient Suitability and Cost-Saving Tips

This therapy may suit people whose asthma is not adequately managed by an inhaled steroid alone. It may not be appropriate for those with significant cardiovascular disease, certain eye conditions, active infections, or severe milk protein allergy. Always use a reliever for sudden symptoms.

To lower overall spending, consider multi-month fills if approved by your prescriber, and set refill reminders before the counter nears zero. Discuss generic mometasone formoterol price differences where relevant, though availability varies by region. Keep your device clean, store it correctly, and bring it to appointments so technique can be checked. These steps help maintain consistency and reduce wasted doses.
