What is Serevent Diskus? 

Serevent Diskus, with the generic name salmeterol xinafoate, is an oral inhalation indicated for long-term maintenance treatment of asthma. It is also used to treat ongoing chronic obstructive pulmonary disease (COPD) with chronic bronchitis and emphysema. This drug prevents and decreases symptoms of breathing problems like wheezing and breathing difficulty. 

This long-acting beta 2 adrenergic agonist works by stimulating an enzyme that allows the conversion of adenosine triphosphate to cyclic adenosine monophosphate, which results in the relaxation of bronchial smooth muscles and inhibition of the release of immediate hypersensitivity mediators. This is available in Serevent Diskus 50 mcg/inhalation. 

How to use Serevent Diskus 

To begin, read the medication information leaflet that comes with this inhaler. Do not use this drug unless you have fully understood all information and instructions printed in the guide. If you need further medical advice or have queries on using Serevent Diskus properly, you may ask your doctor or pharmacist. 

Remember to use this oral inhalation regularly and with a dosing schedule to achieve the best results. Make sure to comply with the instructions given by your doctor. Do not alter your dosage because it depends on your medical condition, response to treatment, and other medications you are taking. In addition, do not stop using this inhaler abruptly. Your dosage will be gradually decreased to avoid rebound effects. 

If you are prescribed with other inhalations at the same time, observe at least a minute of an interval between each medication to allow drug absorption. If you are using this drug in order to prevent asthma caused by strenuous activities such as exercise, make sure to use it 30 minutes before the activity. 

Step by step guide in using Serevent Diskus inhaler: 

  1. Open the foil pouch of the inhaler. On the label, write the date that the pack is opened and the discard date. The discard date should be 6 weeks after the opening date. 
  2. To open the inhaler, hold it with one hand and use the other hand to push the thumb grip open until you see the mouthpiece. You will hear a snap. 
  3. Hold the inhaler in a flat position, mouthpiece facing you. Push the level away from the mouthpiece until you hear a click. The counter in the inhaler should read “1” which means that the diskus is ready to use. 
  4. Breathe out or exhale through your mouth entirely.  
  5. Put the mouthpiece of the diskus inside your mouth and seal your lips around it. Inhale deeply and quickly through your mouth. 
  6. Remove the diskus from your mouth and hold your breath for not less than ten seconds. You may feel or taste the powder of the medication in your mouth.  
  7. Exhale fully and close the diskus by pushing the thumb grip back.
