Seretide

Seretide contains two active ingredients with different functions, salmeterol and fluticasone propionate. Salmeterol works as a bronchodilator – this means that it helps to keep your airways open. Fluticasone propionate is a corticosteroid and is used to reduce swelling, inflammation and irritation in the airways.

Fluticasone propionate is a corticosteroid, it is used to reduce swelling, inflammation and irritation in the airways.

What is Seretide used for?

Seretide is used to keep the airways open and reduce irritation and inflammation in the airways. These properties are useful when treating:

  • Asthma;
  • Chronic Obstructive Pulmonary Disease (COPD).

Seretide is a long-term preventative inhaler that can be used by children (aged 4 and over) and adults. It is used to help prevent attacks of breathlessness and wheezing.

How do you use Seretide to treat asthma and COPD?

Seretide is available in two types of inhaler:

  • An Evohaler (aerosol inhaler);
  • An Accuhaler (which works with powder and capsules).

To use the Evohaler:

  1. Remove the cap from the inhaler and check that it is clean;
  2. Shake the inhaler 4 to 5 times;
  3. Breathe out as far as is comfortable;
  4. Place the mouthpiece in your mouth and form a seal with your lips;
  5. As you start to breathe in press down on the top of the inhaler and keep breathing in;
  6. Remove the inhaler and hold your breath for 3 seconds or as long as is comfortable;
  7. Repeat if required;
  8. Replace the cap firmly once you are finished;
  9. Wash your mouth with water or brush your teeth after taking your inhaler to help prevent thrush.

This inhaler can also be used with a spacer – which helps you take the puff of medication in over several breaths – this is useful if you struggle to press the inhaler and breathe in at the same time or struggle to breathe deeply enough to get the medicine into your airways properly.

To use the Accuhaler:

  1. Open the inhaler by holding the outer case in one hand and putting the thumb of your other hand on the grip, push away from you with your thumb until you hear a click;
  2. Slide the lever away from you as far as it will go until you hear a click, this loads the powder ready for you to inhale, only do this once to release the correct amount of medicine;
  3. Hold the Accuhaler flat and breathe out away from the inhaler;
  4. Place the mouthpiece in your mouth and breathe in deeply;
  5. Remove the inhaler and hold your breath for ten seconds or as long as is comfortable;
  6. Breathe out slowly;
  7. Close the inhaler by sliding the thumb grip towards you until you hear a click – this will also reset the lever;
  8. When you are finished rinse your mouth with water or brush your teeth to help prevent thrush.

If you are unsure how to use your inhaler check with your doctor, nurse or pharmacist as they will be able to help. What is the correct dosage of Seretide?

As with all medication, you should follow the instructions of your doctor or pharmacist when it comes to how much you should take, how often and for how long.

Seretide comes in 3 different doses in each type of inhaler

For the Accuhaler:

  • 50/100;
  • 50/250;
  • 50/500.

As a general rule, these treat mild, moderate and severe asthma from the lowest dose to the highest. Only the strongest dose of 50/500 is used to treat COPD.

For asthma in adults and children 12 and over the dose is:

  • 50/100 – one inhalation twice a day;
  • 50/250 – one inhalation twice a day;
  • 50/500 – one inhalation twice a day. Children aged 4 – 12 years:
  • 50/100 – one inhalation twice a day.

For adults with COPD:

  • 50/500 – one inhalation twice a day.

For the Evohaler the doses are:

  • 25/50;
  • 25/125;
  • 25/250.

For asthma in adults and children 12 or over the dose is:

25/50 – two puffs twice a day;

25/125 – two puffs twice a day;

25/250 – two puffs twice a day. Children aged 4 – 12 years:

25/50 – two puffs twice a days.

A few important points:

  • Take the Evohaler morning and night;
  • Both the Accuhaler and Evohaler should be taken at the same time(s) every day;
  • Continue taking your medicine until your doctor tells you to stop as these are long-term medicines;
  • Do not change the dose without talking to your doctor;
  • Do not use these inhalers if you are suffering from an attack of coughing or wheezing, these are preventative inhalers and will not work in emergency circumstances – you should have a reliever inhaler for this;
  • If you forget to use your inhaler, use it as soon as you remember unless it is almost time for your next dose. In this case, simply skip the missed dose, and never take a double dose to make up for a missed dose.
