Treatment for cough variant asthma
Asthma is treated by avoiding triggers, using "rescue" inhalers when attacks happen and "preventive" inhalers. The doctor may prescribe inhalers for different purposes (prevention and rescue). Other types of inhalers and tablets can be added to improve control. Severe attacks can be life threatening and will need emergency medical care.
