Airpro belongs to a group of medicines called fast-acting bronchodilators or “relievers”. It is used to treat the symptoms of asthma and chronic obstructive pulmonary disease (COPD) such as coughing, wheezing and feeling short of breath. Airpro is called "reliever" inhalers because they give you quick relief from breathing problems when you need it. In most cases, you will be given another inhaler to prevent your symptoms (a “preventer”) and you should use this regularly every day. Airpro works quickly and the effects can last several hours. You can take it at any time of day, but only use it when you notice symptoms, such as coughing, wheezing, shortness of breath and tightness in the chest or you know that you are going to do an activity that can make you breathless. When an asthma attack happens, you should take the number of puffs your doctor recommends. There are several types of inhaler device so make sure you know how to use your inhaler correctly, otherwise it may not work. Do not stop using this medicine unless your doctor tells you to. If you stop, your breathing problems could get worse. Airpro is generally safe and effective but some common side effects include dizziness, vomiting, pain and stuffy nose. These side effects are not often dangerous and they should gradually improve as your body gets used to this medicine. There are other, rarer, side effects and you should call your doctor straight away if you get chest pain, a very bad headache or very bad dizziness. Before using Airpro, you should tell your doctor if you have high blood pressure, an overactive thyroid gland, a history of heart problems, diabetes or low levels of potassium in your blood to make sure it is safe. Also make sure your doctor knows if you are pregnant or breastfeeding before taking this medicine. Because this medicine can make you feel dizzy or shaky, do not drive, cycle or use tools or machinery until you feel better. You should not smoke as it causes damage to your lungs and will make your condition worse.
