In addition, asthma prevention should include identifying allergens and avoiding contact, as well as strengthening the immune system and regularly using preventive medications. Common preventive medications include inhaled corticosteroids, leukotriene receptor antagonists, and cromolyn sodium as anti-inflammatory drugs. During acute attacks, additional use of β2-agonists or theophylline-like drugs may be added. In treatment, inhaled corticosteroids can be used first, and then switched to cromolyn sodium or ketotifen to maintain after the condition stabilizes. For children using ketotifen tablets, it is usually recommended to take 0.5 mg per dose twice a day for those under 3 years old; for those over 3 years old, 1 mg per dose twice a day.
