Seretide Inhalers Online

You can request to buy Seretide online, from our UK registered online pharmacy and doctor service. After completing your assessment and checking out, your order will be passed to our UK registered doctors for review. If approved, our pharmacy team will dispense and dispatch your medication to your chosen address.

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 to stay open. This makes it easier for air to get in and out. The effects last for at least 12 hours. Fluticasone propionate is a corticosteroid which reduces swelling and irritation in the lungs.

What is 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 and it needs to be used long-term to help prevent breathing problems in asthma. It is also known as a ‘steroid’ inhaler.

It is very important that a patient with asthma is on 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, or who wake up in the night more than twice a week should be using a preventer inhaler such as Seretide.

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. Available strengths vary from 50mcg (low dose) to 500mcg (high dose).

If you experience breathing difficulties, or you feel your asthma is no longer controlled, seek medical attention. If you find you are using your inhaler more often than usual, an asthma review with your GP or nurse should be scheduled as soon as possible. 

How does Seretide work?

Both active ingredients work differently to treat asthma:

  • Salmeterol is a long-acting bronchodilator. Bronchodilators help the airways in the lungs open and stay open. They do so by relaxing the muscle. 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.

Inhaled corticosteroids, like fluticasone propionate, are one of the main medicines used to help control Asthma symptoms. They are used to treat asthma in the long-term. By reducing the swelling in the airways they reduce symptoms of asthma such as shortness of breath and wheezing. 

Seretide needs to be used every day to work, even if asthma symptoms improve. This is important because if you stop taking it your symptoms could return or worsen.

Seretide should not be used to treat a sudden attack of wheezing and breathlessness. In these instances a fast acting ‘reliever’ inhaler should be used, such as ventolin.

Alternatives to Seretide

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 such as how severe your asthma is and what other inhalers you use.

Some other corticosteroids that are used for asthma are:

  • Beclometasone
  • Budesonide
  • Mometasone

Examples of branded inhalers that contain other corticosteroids are Pulmicort, Qvar and Flixotide.

Seretide can be used alongside Ventolin (salbutamol) as a treatment for asthma. Seretide is used as a ‘preventer’ and Ventolin is used as a ‘reliever’.

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

This is advised to minimise the chance of getting oral thrush as a side effect.

  • How to clean Seretide?

    Cleaning your inhaler to stop your inhaler blocking, it is important to clean it at least once a week. To clean your inhaler:

    • Wipe the inside and outside of the mouthpiece and the plastic casing with a dry cloth or tissue.
    • Remove the mouthpiece cover.
    • Do not remove the metal canister from the plastic casing at any time.
    • Replace the mouthpiece cover. It will ‘click’ into place when fitted correctly. If it does not ‘click’ into place, turn the mouthpiece cover the other way round and try again. Do not use too much force.

Side Effects

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.

Listed below are some of the more common side effects of Seretide which users may experience:

  • Headaches - this usually improves as treatment continues
  • Oral thrush
  • Muscle pain or cramps

To minimise the chance of getting thrush, you should rinse your mouth out with water and spit it out and/or brush your teeth after taking each dose of your medicine. Using a spacer can also help.
