Did your doctor give you a new inhaler because you have COPD (Chronic Obstructive Pulmonary Disease)? Is it called Aclidinium and Formoterol? Maybe it's under the brand name Duaklir. If so, this article will be very important to you. Since this is a somewhat complicated medication, let's explain everything simply, as if we were talking to a friend.
What actually happens with this inhaler?
Simply put, this inhaler is used to control COPD . It works by widening the airways in your lungs, relaxing them, and making it easier to breathe. Think of it like unclogging a clogged pipe.
It contains two main types of medication. One is Aclidinium, which belongs to the group called ``Anticholinergic``. The other is Formoterol, which is a ``Bronchodilator``. Both of these work together to help keep your airways open.
Very important: This is not a medicine to use when you suddenly have difficulty breathing (COPD flare-up). This is a ``Controller Inhaler'', which is used daily to control symptoms. Your doctor may have given you a separate ``Reliever/Rescue'' inhaler, which is a quick-acting inhaler to use in an emergency.
Things you need to tell your doctor before taking medicine
Before you start using this inhaler, it is very important to talk openly with your doctor about your complete health history, especially if you have any of the following conditions:
- Asthma
- Diabetes
- Glaucoma, a disease of increased pressure in the eyes
- Heart disease or high blood pressure
- Irregular heartbeat
- Kidney or Liver disease
- Prostate problems
- Seizures
- Thyroid disease
- If you have an allergic reaction to these medications, namely Aclidinium, Formoterol, Atropine , or milk proteins .
- If you have allergies to any other medicine, food, or dye.
- If you are pregnant or trying to get pregnant.
- If you are a mother who is breastfeeding a child.
It is very important for your safety to say these things without hiding them.
How to use the inhaler correctly?
This is an inhaled medication. Use it only as directed by your doctor, and only as often as prescribed.
- Try to use it at the same time every day . Once you make this a habit, you'll be less likely to forget.
- Do not stop taking the medicine until your doctor tells you to. Continue taking it even if your symptoms subside.
- Do not use more than the prescribed amount. Doing so will not make you feel better faster, but it may increase side effects.
What to do if the dose increases (overdose)?
If you think you have overdosed, immediately call the National Poisons Information Centre at the Colombo National Hospital . Or go to the nearest hospital Emergency Department (ETU) immediately.
What if I miss a dose?
If you forget to take a dose, take it as soon as you remember. But if it is almost time for your next dose, skip the missed dose and take the next dose at the scheduled time. Never take two doses at the same time.
Can this interact with other medications?
Yes, this is a very important question. This inhaler can interact with some other medications. So tell your doctor about all the medications you are taking, not just the ones prescribed by your doctor, but also the ones you buy from the pharmacy, vitamins, traditional medicines (Sinhala medicine), and even your eating habits (alcohol, smoking).
