If you or someone you love lives with chronic obstructive pulmonary disease, your doctor may have prescribed a new combination inhaler. You might see the active medicines listed as aclidinium and formoterol, or you might know the medicine by its brand name, such as Duaklir. Navigating a new respiratory medicine can feel overwhelming at first. Let us walk through everything you need to know in clear, simple terms so you can breathe easier and feel confident about your daily routine.
Living with chronic lung conditions requires careful management, and understanding your daily controller inhaler is a powerful step toward better health. This guide is written to help you grasp how your medicine works, how to use it safely, and what signs require immediate medical attention. Let us explore the details together.
Key Takeaways at a Glance
- This combination inhaler is a daily controller medicine for chronic obstructive pulmonary disease, not a fast-acting rescue inhaler.
- Aclidinium relaxes airway muscles over time. This formoterol opens your breathing tubes to make airflow smoother.
- Always take your prescribed dose at the exact same time every single day as directed by your doctor.
- Share your complete medical history and list all other medicines with your doctor before starting treatment.
- Watch closely for any unexpected breathing difficulties right after inhaling and contact your doctor right away if they occur.

What Does This Inhaler Actually Do?
Simply put, this inhaler is designed to help control your chronic obstructive pulmonary disease symptoms. It works by opening up the airways inside your lungs, relaxing tight muscles, and making your breathing much easier. Think of it like clearing out a narrow garden hose so water can flow freely without any blockages.
This medicine combines two active ingredients to achieve powerful results. The first ingredient is aclidinium, which belongs to a class of medicines called anticholinergics. The second ingredient is formoterol, which belongs to a class called long-acting beta-agonists. Both medicines work hand in hand to keep your breathing passages open day and night.
Important Distinction: This medicine is a daily controller, not a rescue treatment. It will not stop a sudden breathing flare-up right away. Your doctor should provide a separate fast-acting rescue inhaler for sudden emergencies.
Things to Tell Your Doctor Before Starting
Before you begin using this inhaler, open up and share your complete health history with your doctor. Certain medical conditions require special caution, so let your doctor know right away if you have any of the following health issues:
- A history of asthma or other chronic respiratory conditions.
- Diabetes or high blood sugar levels.
- Eye pressure problems, especially narrow-angle glaucoma.
- Heart disease, chest pain, or high blood pressure.
- An irregular heartbeat or heart rhythm disturbances.
- Kidney disease or chronic liver problems.
- Enlarged prostate gland or difficulty with urination.
- A history of seizures or convulsive disorders.
- Thyroid gland disorders.
- Allergies to aclidinium, formoterol, atropine, milk proteins, or any other substances.
- Allergies to specific foods, dyes, or preservatives.
- Pregnancy, planning to become pregnant, or breastfeeding.
Sharing these details openly protects your safety and helps your doctor tailor your treatment plan effectively. Never keep medical secrets from the professional caring for your lungs.

This medicine is designed to be inhaled directly through your mouth into your lungs. Always follow your doctor instructions precisely regarding how many puffs to take and how often to use your device.
- Try to use your inhaler at the exact same time every single day to build a healthy routine.
- Never stop taking your medicine without talking to your doctor first, even if you feel much better.
- Do not take more puffs than prescribed. Taking extra medicine will not help you heal faster and can increase side effects.
- Keep track of your dose counter so you always know when your medicine is running low.
What to Do in Case of an Overdose
If you suspect that you or someone else has used too much of this medicine, take action right away. Call your local emergency services or poison control center right away. In the US, call 911. In the UK, call 999. In other regions, visit your nearest hospital emergency department as quickly as possible.
What to Do If You Miss a Dose
If you forget to take your scheduled dose, take it as soon as you remember later that day. However, if it is almost time for your next scheduled dose, skip the missed dose entirely and stay on your normal schedule. Never take two doses at the same time to make up for a missed one.
Can Other Medicines Interfere with This Inhaler?
Yes, potential drug interactions are very important to consider. This inhaler can interact with various other pharmaceutical products. Make sure your doctor and pharmacist know about every single item you take, including prescription drugs, over-the-counter medicines, vitamins, herbal supplements, and lifestyle habits like smoking or alcohol use.
| Medicine Category | Examples and Details |
|---|---|
| Do Not Use Together | Other long-acting beta-agonists like indacaterol, olodaterol, or salmeterol. Certain heart medicines such as cisapride, dofetilide, dronedarone, pimozide, or thioridazine. |
| Inform Your Doctor If Using | Antihistamines for allergies, monoamine oxidase inhibitors for depression, other anticholinergic drugs like ipratropium or tiotropium, theophylline, and treatments for bladder issues or Parkinson disease. |
Things to Watch Out For and Possible Side Effects
As you use your daily inhaler, pay close attention to how your breathing feels and whether your symptoms improve or worsen over time. Share your observations during your regular medical checkups.
Emergency Warning Signs
Never use this daily controller inhaler for sudden breathing emergencies. Keep your rescue inhaler nearby at all times. If you find yourself needing your rescue inhaler often, your condition is not properly controlled. Contact your doctor right away. If you experience severe chest pain, sudden swelling of your face or lips, or extreme trouble breathing, call 911 (US/Canada), 999 (UK), or go to the nearest emergency room right away.
Sometimes, using an inhaler can paradoxically trigger sudden tightness or wheezing in your chest right after administration. If this happens, stop using the inhaler right away and contact your doctor for further guidance.
