Thanks for your question on Healthcare Magic. I can understand your concern. By your history and description, possibility of asthma is more likely in your daughter s case. Best treatment of asthma is inhaled treatment. Inhaled bronchodilators (formoterol or salmeterol) and inhaled corticosteroid (ICS) (budesonide or fluticasone) is best for asthma. Seroflo is having salmeterol and fluticasone. It is appropriate for her disease. Inhaled drugs act directly on lungs without causing systemic side effects. So inhaled drugs are very safe and effective for long term use. Her tremors are mostly due to levolin. She can stop levolin and start duolin inhaler to prevent tremors. So don t worry about habit formation and side effects of inhaler. Hope I have solved your query. I will be happy to help you further. Wishing good health to your daughter. Thanks.
