Asthma medications are primarily used to treat the symptoms of asthma and prevent future asthma attacks. Depending on the severity of the condition, there are various types of medications available for controlling asthma. Short-acting bronchodilators such as albuterol can be used to immediately relieve wheezing, coughing and chest tightness during an asthma attack. Long-term control medications such as inhaled corticosteroids can help reduce inflammation in the airways and control symptoms over time, while leukotriene modifiers can also work to prevent attacks and improve symptom control. Additionally, other medications such as cromolyn sodium and nedocromil are often prescribed when short-term relief is needed but more frequent use of a rescue inhaler isn’t ideal. Often times, doctors may suggest combinations of multiple different drugs in order to find the best treatment for a patient's specific needs. Asthma medication should be used as prescribed by a doctor in order to ensure maximum effect and safety from side effects such as tremors, increased heart rate and shakiness. In addition to avoiding triggers that could worsen asthmatic episodes (such as smoke or pollen), it is crucial for people with asthma to take their medications regularly and consistently in order to keep their condition under control.
