About Seretide

Seretide is a prescription only inhaled medication used in the treatment of asthma. The inhaler contains two medicines: salmeterol and fluticasone propionate.

It is sometimes called a ‘preventer’ inhaler. It should be used long-term to help prevent breathing problems in asthma. It is also known as a ‘steroid’ inhaler.

It is important that a patient with asthma is using the correct treatment to ensure their symptoms are kept under control. Patients who use their reliever inhaler such as Ventolin, Salbutamol or Salamol more than twice a week, should be using a preventer inhaler such as Seretide.

The Difference Between Blue and Brown Inhalers

After an online consultation, our doctors can prescribe two different types of Seretide inhalers called Accuhalers and Evohalers. You can read how to use the different types of inhaler here. The accuhaler is available in three strengths: 100 mcg, 250 mcg, and 500 mcg. The Evohaler is available as Seretide 50 mcg, Seretide 125 mcg, and Seretide 250 mcg.

Some people find the Accuhaler easier to use because you don’t have to synchronise pressing the button with your breathing. The Accuhaler is a circular inhaler that contains dry powder.

How does Seretide work?

Seretide contains two medicines: salmeterol and fluticasone propionate. These ingredients work together to help prevent asthma attacks.

Salmeterol is a long-acting bronchodilator. Bronchodilators help the airways in the lungs open and stay open. This helps to relieve asthma symptoms, like shortness of breath. This makes it easier for air to pass through the airways. It is long-acting which means it helps keep the airways open for at least 12 hours.

Fluticasone propionate is a corticosteroid. It helps treat asthma by reducing the swelling in the airways of the lungs.

How do I use Seretide?

There are two different types of Seretide inhalers available and each is used in a different way. See the Asthma UK videos on how to use the Evohaler and the Accuhaler. Your doctor will tell you how many puffs to take every day. Usually the prescribed dose is two puffs twice a day for the Evohaler and one puff twice a day for the Accuhaler.

Seretide alternatives

There are a number of other ‘preventer inhalers’ available to treat asthma. Your GP or asthma nurse/pharmacist will decide the right inhaler for you based on a number of factors. Two factors they consider are how severe your asthma is and what other inhalers you use.

Examples of other preventer inhalers include Clenil (contains beclometasone) and Flixotide (contains fluticasone). 

Other asthma medications contain a combination of steroids and long-acting bronchodilators, which open up your airways. One example of a combination inhaler is Symbicort Turbohaler.

What is Seretide inhaler used for?

The inhaler is used to treat asthma and chronic obstructive pulmonary disease (COPD). It contains two ingredients that work in combination on the lungs to improve asthma symptoms. Simple Online Pharmacy doctors can only prescribe Seretide online for asthma.

Is Seretide a steroid inhaler?

The inhaler contains a corticosteroid meaning it is a steroid inhaler. This is different to anabolic steroids sometimes used by athletes to add muscle mass.

Why should you rinse your mouth out after using an inhaler?

Patients are advised to do this because it minimises the risk of developing oral thrush as a side effect.

Side Effects

Seretide Side Effects

Seretide is a well-tolerated medicine, however, there is always a risk of side effects when taking any medicine. It is important to read the patient information leaflet to be aware of the potential side effects. 

Common side effects of this inhaler include headaches, oral thrush, muscle cramps, a hoarse voice, and an irritated throat.

Oral thrush is a common side effect of any steroid inhaler. To minimise the chance of getting thrush, you should rinse your mouth out with water and spit it out or brush your teeth after each dose of Seretide. Using a spacer device can also help to minimise the risk of getting oral thrush.
