What is Seretide?

Seretide is a combination inhaler used to manage and control asthma. As a preventer inhaler, it is used daily to stop symptoms from flaring up and causing an asthma attack. It combines corticosteroids with a bronchodilator to both soothe inflammation and open the airways.

Why do I need to use Seretide regularly?

Seretide needs to be used daily to keep your asthma under control. It prevents your symptoms from flaring up or leading to an asthma attack, allowing you to breathe more easily and to depend less on your reliever inhaler. You need to keep using it, even if you feel better. If you stop using it, your symptoms may start to get worse.

Will Seretide treat an asthma attack?

Seretide cannot be used to treat an asthma attack. Only your blue reliever inhaler should be used in the event of an asthma attack. Seretide is for prevention only and cannot relieve symptoms after they have occurred.

Which ingredients can cause an allergic reaction?

However, if you know you are allergic to any of the active or inactive ingredients please let your doctor know. Make sure to get emergency medical treatment if you experience trouble breathing, a skin rash or itchiness after taking this medication.


Seretide dosage

The standard dosage of Seretide is 1–2 puffs twice a day. Always follow the prescribing doctor’s instructions when taking Seretide.

How to start taking Seretide

Start taking Seretide as soon as you have been prescribed the inhaler. It's usually taken once in the morning and once in the evening. Seretide is often prescribed for people whose asthma has gotten worse or if one type of preventer medicine has not proved effective for keeping it under control.

How to take Seretide Evohaler

Before using your Seretide Evohaler for the first time, test it by taking the cap off, shaking the canister and pressing down on the button to release a puff into the air.

When you’re ready, shake the inhaler and sit or stand upright. Seal your lips around the mouth of the inhaler and start to breathe in. At the same time, press down once on the canister to release the medication,  and keep breathing in as long as comfortable. Hold your breath for a few seconds, if comfortable, before breathing out again. If you need to take a second puff, wait 30 seconds and then repeat the process.

How to take Seretide Accuhaler

Seretide Accuhaler is a dry powder inhaler. Before each use, open the outer case to reveal the mouthpiece. Then slide the plastic lever all the way back. This releases the medication ready to be inhaled. When you are ready, breathe out fully before sealing your lips around the mouthpiece. Breathe in slowly and deeply, holding your breath for up to ten seconds before exhaling. Repeat these steps if you need to take two puffs.

How and when to stop taking Seretide

You should not stop taking Seretide unless your doctor advises you to do so. Seretide must be taken daily as prescribed. It is a long term form of treatment, and your doctor will regularly review your condition to ensure the inhaler is working correctly. If you experience troublesome side effects, speak to your doctor before stopping Seretide.

What should I do if I find I’ve used Seretide more regularly than I should have?

Using more Seretide than you should have is unlikely to be harmful, but you should inform your doctor or pharmacist. Keep using your Seretide inhaler exactly as your doctor has prescribed. If your symptoms are not controlled, speak to your doctor rather than increasing the dose yourself.

What should I do if I forget to use Seretide?

If you have forgotten a dose of Seretide, then take it as soon as you can unless it's nearly time for your next one. You should never take double the dose to make up for a missed one.

How to cope with side effects of Seretide?

Treatment Options

Seretide vs. Symbicort

Seretide and Symbicort are both combination inhalers that work in similar ways to reduce inflammation in the lungs and to relax and widen the airways to breathe easier. Seretide contains fluticasone and salmeterol, whereas Symbicort contains budesonide and formoterol.

Seretide Evohaler vs. Seretide Accuhaler

The Seretide Evohaler is a metered-dose inhaler (MDI) which releases the medicine in the form of a spray or mist when the user presses down on the top of the canister. It can feel trickier to use as you must press down on the canister and breathe in simultaneously. The medicine contained in the Accuhaler is a dry powder, each dose being released before you breathe it in. This model may be more suitable for children and teenagers as it does not require two actions at once.

Seretide vs. other asthma inhalers

Seretide is a combination inhaler which means it has a more substantial effect than single medicine inhalers. It can help to manage more severe asthma, as well as COPD. However, as a preventer inhaler, it cannot be used to treat an asthma attack, so it's essential to have your reliever inhaler to hand in case you need it.
