Serevent (Salmeterol) is a long-acting beta2-adrenoreceptor agonist (LABA) bronchodilator. It is used to prevent asthma attacks or exercise-induced bronchospasm. It is also used to treat chronic obstructive pulmonary disease (COPD), including emphysema and chronic bronchitis. Serevent Diskus needs regular use in order to be effective. Do not use Serevent Diskus to treat a current asthma attack. It is not a rescue inhaler and will not work. Be sure to use the appropriate inhaler if you are having an attack. Serevent Diskus works due to its bronchodilator properties. Beta-2 agonists are medications that stimulate the beta-2 receptors on the smooth muscle cells that line the airways, causing these muscle cells to relax, which in turn leads to the opening of the airways. Also, Serevent Diskus is effective in blocking mast cells from releasing histamines, which is a natural chemical that causes tissue swelling and other allergic reaction in the body. By blocking this, Serevent further prevents the airways from narrowing and allows for easier breathing.
Serevent inhaler is available from United Kingdom also called Serevent Evohaler by GSK in the dosage of 25 mcg/120 dose. The Serevent Diskus comes from Canada by GSK and it is available in the dosage of 50 mcg/60 dose. The generic alternative, salmeterol, is currently not available.
Common side effects of Serevent include headache, flu symptoms, joint or muscle pain, throat irritation, cough, or stuffy or runny nose. Contact your doctor if you experience more serious side effects such as worsening asthma symptoms or other breathing problems after using Serevent, severe headache, blurred vision, pounding in your neck or ears, chest pain or irregular heartbeats, tremors or nervousness, signs of high blood sugar, or signs of low potassium levels. If you experience any serious side effects or signs of an allergic reaction, see emergency medical attention.
You should not use Serevent Diskus if you are allergic to salmeterol or to milk proteins. To make sure Serevent is safe for you, tell your doctor if you have ever had a food or drug allergy, heart disease or high blood pressure, epilepsy, diabetes, a thyroid disorder, or liver disease. Talk to your doctor if you are pregnant or breastfeeding in order to discuss any possible risks.
