Initial dose based on previous asthma drug therapy and disease severity; 100 mcg via oral inhalation once daily is the usual recommended starting dose for patients not on an inhaled corticosteroid. After 2 weeks of therapy, if asthma symptoms are uncontrolled, increase dose to 200 mcg via oral inhalation once daily. Max: 200 mcg once daily. Administer at the same time each day. The maximum beneficial effect may not be achieved for up to 2 weeks or longer after starting treatment. Titrate to the lowest effective dose once asthma stability is achieved.
Whilst the use of inhaled steroids and long acting beta-adrenoceptor agonists (LABA) are recommended in asthma guidelines for the resulting improved symptom control,  concerns have been raised that salmeterol may increase the small risks of asthma deaths and this additional risk is not reduced with the additional use of inhaled steroids.  Other side effects from this drug combination may include increased blood pressure, change in heart rate, an irregular heartbeat, increased risk of osteoporosis, cataracts, and glaucoma.
