Salmeterol, sold under the brand name Serevent among others, is a medication used in the maintenance of asthma or chronic obstructive pulmonary disease (COPD). In asthma it is used together with a inhaled corticosteroid. It is also used for exercise-induced bronchoconstriction. Effects may begin in about 30 min and last about 12 hours.

Common side effects include headache, runny nose, thrush, cough, and change in voice. Other side effects may include low potassium, anaphylaxis, bronchospasm, and QT prolongation. Use during pregnancy or breastfeeding is deemed reasonable. It is a long-acting β2 adrenergic receptor agonist (LABA).

Salmeterol was patented in 1983 and came into medical use in 1990. In the United Kingdom 120 doses costs the NHS about £30 in 2021. This amount in the United States costs about 800 USD. It is also avaliable as fluticasone/salmeterol.
