Singulair is also known by the generic name Montelukast


USES:
Montelukast is used regularly to prevent the wheezing and shortness of breath caused by asthma and decrease the number of asthma attacks. Montelukast is also used before exercise to prevent breathing problems during exercise (bronchospasm). This medication can help decrease the number of times you need to use your rescue inhaler. This medication is also used to relieve symptoms of hay fever and allergic rhinitis (such as sneezing, stuffy/runny/itchy nose).

This medication does not work immediately and should not be used to treat sudden asthma attacks or other breathing problems.

This drug works by blocking certain natural substances (leukotrienes) that may cause or worsen asthma and allergies. It helps make breathing easier by reducing swelling (inflammation) in the airways.

Symbicort is also known by the generic name Budesonide-Formoterol


USES:
This product is used to control and prevent symptoms (wheezing and shortness of breath) caused by asthma or ongoing lung disease (such as COPD). It contains 2 medications:
budesonide and formoterol. Budesonide belongs to a class of drugs known as corticosteroids. It works by reducing the irritation and swelling of the airways. Formoterol belongs to the class of drugs known as long-acting beta agonists. It works by opening airways in the lungs to make breathing easier. Controlling symptoms of breathing problems can decrease time lost from work or school.

This medication must be used regularly to be effective. It does not work immediately and should not be used to relieve sudden asthma attacks. If an asthma attack occurs, use your quick-relief inhaler (such as albuterol, also called salbutamol in some countries) as prescribed.
