What is the dosage for salmeterol?

Salmeterol inhalations should not be used more often than prescribed (twice per day) and proper techniques of inhalation closely followed. Salmeterol is metabolized by the liver and should be used with caution in patients with liver dysfunction. Salmeterol is not meant to be used in treating acute asthma attacks; short acting inhaler medications are used for acute attacks. When using salmeterol in preventing exercised induced asthma, the medication is administered 30 to 60 minutes before exercise. Salmeterol does not take the place of oral or inhaled corticosteroids.

Which drugs or supplements interact with salmeterol?

Salmeterol can increase heart rate, blood pressure, and cause chest pain and excitement, especially if used in higher doses than recommended or used in those with coronary heart disease or high blood pressure. Tricyclic antidepressants and salmeterol should not be combined because of additive effect on the vascular system. In rare instances, salmeterol can induce paradoxical worsening of bronchospasm (which can be life-threatening). If this occurs, salmeterol should be discontinued, and the doctor notified immediately. Rare allergic reactions to salmeterol can cause skin rash, hives, swelling, bronchospasm, and anaphylaxis. Worsening of diabetes and lowering of potassium have also been described.
