medication to help with severe asthma
These oral medications â including montelukast (Singulair), zafirlukast (Accolate) and zileuton (Zyflo) â help relieve asthma symptoms for up to 24 hours. In rare cases, these medications have been linked to psychological reactions, such as agitation, aggression, hallucinations, depression and suicidal thinking.
These include: 1  Allergy shots (immunotherapy). Over time, allergy shots gradually reduce your immune system reaction to specific allergens. 2  Omalizumab (Xolair). This medication, given as an injection every two to four weeks, is specifically for people who have allergies and severe asthma.
