Dulera® Inhaler for Asthma

Dulera® is a maintenance inhaler used to help control persistent asthma. It combines an inhaled corticosteroid with a long-acting bronchodilator to reduce airway inflammation and improve breathing over time. If you pay Dulera without insurance, our US delivery from Canada model can help you explore lower out-of-pocket options.

What Dulera Is and How It Works

Border Free Health connects U.S. patients with licensed Canadian partner pharmacies; prescriptions are verified with prescribers before dispensing.

Dulera pairs mometasone furoate, an anti-inflammatory steroid, with formoterol fumarate, a long-acting beta2-agonist that relaxes airway muscles. Together, they help prevent symptoms such as wheeze, chest tightness, and nighttime awakenings. This is a controller, not a rescue inhaler, and it does not treat sudden bronchospasm. Keep your quick-relief inhaler available for acute symptoms per your clinician’s guidance. As a Asthma controller, the medicine is taken regularly, even when you feel well.

The Mometasone formoterol inhaler works by addressing both airway swelling and bronchoconstriction. Mometasone reduces inflammatory mediators in the lungs. Formoterol helps keep the airways open for many hours. You should not use additional long-acting beta-agonists with this treatment. If control is inadequate, speak with your healthcare professional about your plan.

Who It’s For

This treatment is indicated for the maintenance therapy of asthma in patients for whom a combination inhaled corticosteroid and long-acting bronchodilator is appropriate. It is not for relief of acute symptoms or for the primary treatment of status asthmaticus. People with known hypersensitivity to any component should avoid use.

Tell your prescriber about eye problems, bone health concerns, infections, tuberculosis, or exposure to chickenpox or measles. Discuss any heart rhythm issues, high blood pressure, thyroid disease, or seizure history. Children and adolescents may be more sensitive to growth effects; height should be monitored over time. For COPD, ask your clinician about approved options.

Dosage and Usage

Use two inhalations twice daily, about 12 hours apart, or as directed on your prescription label. Shake well before each puff. If using a spacer, review device instructions from your clinician or pharmacist.

• Prime before first use and if not used for several days
• Exhale fully, seal lips around the mouthpiece, and inhale slowly during actuation
• Hold your breath for up to 10 seconds, then exhale gently
• Wait brief moments between puffs if two are prescribed
• Rinse mouth and spit after use to reduce the risk of thrush

Do not exceed your prescribed number of inhalations. If symptoms worsen or you need your rescue inhaler more often, contact your prescriber. Refer to the official label for full directions.

Strengths and Forms

This HFA metered-dose inhaler is available in commonly published strengths: 100/5 mcg and 200/5 mcg per actuation. Canister counts may vary by market. The Zenhale inhaler name is used in certain regions; availability and packaging can differ by country.

Missed Dose and Timing

If you miss a dose, take it when you remember unless it is close to the next dose. If it is almost time for the next scheduled dose, skip the missed one and resume your regular schedule. Do not take extra puffs to make up for a missed dose. Consistency matters for controller inhalers, so consider reminders or a routine tied to morning and evening activities.

Storage and Travel Basics

Store the inhaler at room temperature away from extreme heat, open flame, and freezing conditions. Keep the cap on when not in use. Do not puncture the canister. Keep out of reach of children and pets. When traveling, keep the inhaler in your carry-on bag and bring a copy of your prescription. Airport security is familiar with inhalers, but having documentation can help. If you are sourcing from Canada, maintain the original packaging for identification during travel.

Benefits

The combination therapy can simplify your daily routine by pairing anti-inflammatory control with long-acting bronchodilation in one device. The Dulera inhaler may reduce daytime symptoms, nighttime awakenings, and the need for rescue medication for many patients. Using a single controller can also support adherence compared with multiple separate inhalers. Always evaluate response with your healthcare professional and follow the written asthma action plan.

Side Effects and Safety

• Throat irritation or hoarseness
• Oral thrush or mouth discomfort
• Headache
• Cough
• Nasal congestion
• Upper respiratory tract infection

Serious but less common risks include paradoxical bronchospasm, effects on the heart such as palpitations, changes in blood pressure, or chest pain, and allergic reactions like rash, swelling, or breathing difficulty. Inhaled steroids can contribute to cataracts, glaucoma, reduced bone mineral density, and adrenal suppression, especially at higher exposures. Children and adolescents may experience growth effects; routine monitoring is advised. Report any significant worsening of breathing, faintness, or signs of infection promptly.

Drug Interactions and Cautions

Tell your prescriber about all medicines and supplements. Strong CYP3A4 inhibitors such as ketoconazole or certain antivirals can increase steroid exposure. Beta-blockers may reduce bronchodilation. Other adrenergic agents, MAO inhibitors, certain tricyclic antidepressants, or diuretics may raise the risk of cardiovascular effects or low potassium when combined with a Mometasone furoate formoterol inhaler. Avoid using additional long-acting beta-agonists with this therapy. If you need frequent rescue puffs, seek medical advice.

What to Expect Over Time

Some people notice smoother breathing patterns after consistent use for several days, while others may need longer to gauge benefit. Symptom control depends on your asthma severity, inhaler technique, and adherence. Regular follow-up helps your clinician assess step-up or step-down decisions. Keep tracking symptoms, nighttime awakenings, and rescue use to guide discussions.

Compare With Alternatives

Other asthma controllers include budesonide/formoterol combinations and once-daily inhaled corticosteroids. You can review class comparisons in our article Breyna Vs Symbicort. As another option, some patients use a long-acting muscarinic antagonist add-on such as Lupin® Tiotropium after clinician review. For corticosteroid-only choices, see Arnuity Ellipta Alternatives.

Availability and Substitutions

Availability can vary by strength and region. If a specific presentation is temporarily out of stock, your prescriber may recommend a therapeutically appropriate alternative in the same class or a different controller strategy. We do not list restock dates. Your clinician’s plan should guide any substitution.

Patient Suitability and Cost-Saving Tips

Good candidates are patients whose asthma warrants a combination inhaled corticosteroid and long-acting bronchodilator and who can commit to twice-daily use. Those with uncontrolled hypertension, significant arrhythmias, or recurrent infections require careful review before starting. If you are sensitive to milk proteins, verify excipients on the label.

• Ask about a multi-inhaler supply to reduce refill frequency
• Coordinate refills to avoid gaps before travel
• Use reminders to improve adherence and symptom control
• Review inhaler technique at each visit to maximize benefit
• Discuss step-down strategies once stable for an extended period
