Inhalers are used to control the asthma attack at that instant. However the use of asthma inhalers varies from one asthmatic sufferer to another depending upon the intensities of their attack. Basically inhalers like proventil (albuterol) and singular are commonly used but there many more inhalers that may be much better for one asthmatic patient than another. It is typically based on trial and error technique.

Asthma inhalers should not be used by those who have severe or uncontrolled asthma as they need long term medication rather than aid just at the time of attack. Asthmatic need to control symptoms from getting worse but an inhaler does not do so but it gives a short term relief during an asthma attack.

Also the asthma patient should immediately stop using inhalers who on using inhalers develops certain side effects like cough, irritation in throat, dizziness, loss of appetite, lightheadness, heartburn, allergic reactions, upset stomach, headache or vomiting. 

People with heart problems should be cautious while using ipratropium and salbutamol combination inhaler since proper technique is required with all inhalers. Some infants, young children and elderly people find it difficult to use inhalers and therefore are asked to use nebulizers. A physician can better determine and recommend the best type of inhaler for a specific patient.
