How to buy Seretide?

Buying Seretide is simple and becoming an increasingly popular method. To save the time returning to the doctor's surgery in-person for a repeat prescription, you can order online here. All inhaler medications require a quick consultation to ensure the medication is going to be highly effective for your particular strain of asthma. This is no exception at NEW HEALTHSITE with a five-minute questionnaire reviewed by a certified medical professional, very similar to a face-to-face appointment.

If you need Seretide in a hurry, that's no problem. When ordered before 4.30pm, you will receive your treatment the very next day before 1pm. If you live within a London postcode, this can be same day delivery.

Is it safe to order online?

When ordering from a certified online pharmacy, you can be ensured that your medication is safe. If the pharmacy doesn't ask you to complete essential health and medical question, however, this is a telltale sign that the website isn't certified. The website should also display clear signs that it is registered and approved by the relevant authorities. In the UK, this includes being registered by the MHRA, GMC .

All medication will be delivered in tamper proof packaging complete with the full patient leaflet, which confirms that the medication is clinically proven and highly effective.

What is included in the price?

When ordering Seretide online here at HEALTHSITE, this is an all-inclusive price including the prescription, consultation, medication and delivery. There are no hidden costs. The price adjusts depending on the dosage and quantity you have ordered, which can be seen below:

Can you buy without a prescription?

It's not possible to buy Seretide over the counter. This is because your personal health history and current medications must be taken into account. A doctor can safely prescribe Seretide for you.

What Is Seretide?

Seretide is used to control asthma before an attack can happen. It contains the following two active ingredients:


Fluticasone is a synthetic corticosteroid. Your body naturally produces corticosteroids in the adrenal glands to tackle inflammation. Fluticasone is absorbed into the lungs to prevent the chemical reactions that create inflammation. During an asthma attack, your inflamed airways tighten and make it difficult to breathe. By preventing this inflammation, Fluticasone stops asthma attacks before they can begin.


Salmeterol is a long-acting beta 2 agonist. Your lungs contain beta 2 receptors and the term 'agonist' simply means 'stimulating action'. Salmeterol stimulates action in the beta 2 receptors in your lungs that make them relax and open up. This action eases your breathing, wheezing and chest pain.

Sometimes Salmeterol is sometimes called a long-acting Bronchodilator (LABA) instead.

Seretide is not a reliever inhaler that you take during an asthma attack because it only contains long-acting beta 2 agonists. Reliever inhalers contain short-acting beta 2 agonists that open your airways more rapidly. However, Seretide lasts longer and is an effective preventer when taken correctly.

Some people are under the impression that corticosteroids are the anabolic steroids some bodybuilders use to gain extra muscle. Corticosteroids are an entirely different class of medication. Users cannot become addicted to Seretide and it will not affect your body shape.

How Does Seretide Work?

Seretide is taken as an inhaler meaning you breathe the medicine directly into your lungs where it's needed. The active ingredients are then absorbed by the blood to reduce inflammation and stimulate your lungs to relax. Reliever inhalers are generally used by those whose asthma is not managed using a reliever inhaler at the point of an attack.

Whether you have recently been diagnosed with asthma, or have long become accustomed to using an inhaler, it is advised to check your inhalation technique. Up to a third of asthmatics use their inhaler incorrectly, which means asthma medicines are not as effective as they could be.

Uncontrolled asthma is dangerous. Asthmatics should have a yearly review with their health professional. It's worth remembering that your local pharmacy or practice nurse is available with support at any time, including observation of inhalation technique.

How To Use Seretide

Seretide is usually taken twice a day by those with asthma that needs more management than a reliever can provide. However, dosage instructions should be prescribed by a doctor. Everyone is different and requires differing dosages of medication to control their condition, asthma is no exception.

Seretide is available in two inhaler forms:


This is a metered dose inhaler (MDI). An Evohaler sprays the active ingredients out in a mist that you immediately and sharply inhale. It requires some coordination as the canister must be depressed at the point of breathing in. Children, older people and those with hand difficulties may find an Evohaler is not the best option for them.

The Evohaler can be used alongside a spacer. Spacers are attachments that clip onto the inhaler to cover your mouth and nose area. You can then breathe in the mist at a slower pace. Ensure that the spacer is the same make as your Evohaler so the fit is tight enough to contain the whole dose.


This is a dry powder inhaler that doesn't require a spacer. It's activated by breathing. You turn a lever to remove the top of the blister pack. The medicine is then taken by breathing in slowly and steadily.

Regular use of Seretide will bring asthma symptoms under control but it's important to keep taking the medicine even if your asthma symptoms subside. It's likely they will return if Seretide is not taken as prescribed.

Seretide Side Effects

Although the majority of people are able to take Seretide safely it may cause some side effects.

Side effects include:

  • Headache
  • In COPD patients experience colds, sinusitis, pneumonia, bronchitis and bone fracture or bruising
  • Oral thrush caused by the corticosteroid element. Thrush is a fungal infection that causes white patches in your mouth. Rinsing with water after taking Seretide or using a spacer can help.
  • Low levels of potassium
  • Sore throat or hoarseness
  • Muscle cramps or pain in the joints and muscles
  • Tremors
  • Palpitations or tachycardia
  • Anxiety
  • Sleep disorders
  • Chest pain

Rarer side effects include:

  • Narrowing of airways immediately after use
  • Abnormal heartbeat
  • Cushing's Syndrome in long term use
  • Glaucoma in long term use
  • Cataracts in long term use
  • Hyperactivity or other behavioural change
  • Suppression of adrenal gland function in long term use
  • Osteoporosis

You should always read the manufacturer's list of possible side effects to be completely informed about your medicines.

Seretide Dosages

Taking the correct dosage of Seretide is important. Most people are advised to begin with a lower dose and increase this if symptoms are not brought under control. Although it's generally taken twice a day, this pattern can be altered to suit individual circumstances, for example, if your asthma symptoms are worse at night your doctor may suggest one dosage is taken before bedtime.

The Seretide accuhaler is available in three different dosages which are all pre-dispensed ready for inhalation.

  • 50 microgram/100 microgram
  • 50 microgram/250 microgram
  • 50 microgram/ 500 microgram

Patients with Chronic Obstructive Pulmonary Disease (COPD) should take the 50/500 accuhaler as it is the only one with the correct dosage for the disease.

The Seretide Evohaler is available in three different forms which are all pre-dispensed ready for inhalation.

  • 25 microgram/50 microgram
  • 25 micrograms/125 micrograms
  • 25 micrograms/250 micrograms

The prescriber will assess which is best for your needs at the time of consultation.

If a dose is forgotten it's not necessary to take it at a later time. You should proceed to the next dosage without filling in with the missed one or doubling up.

Seretide Precautions

It's important to know that Seretide is a preventative medicine not a reliever, so it's not suitable for use at the point of an asthma attack. The medication needed for this is Salbutamol that is found in Ventolin for example. Salbutamol swiftly relaxes your airways.

Asthmatics should consult their doctor if they find that their prescribed dose of asthma medication is not helping and symptoms are worsening or increasing. Symptoms can increase for no apparent reason or sometimes exacerbate during the hay fever or cold and flu seasons. An increase in symptoms often means a new dose is required.

Seretide is a safe and clinically proven medication when it's taken at the prescribed dose, but there are some people who are advised not to use it.

These are people with:

  • An allergy or sensitivity to the ingredients
  • Children under the age of four

People who have, or who have had, the following should speak to their doctor about using Seretide:

  • An overactive thyroid (hypertension)
  • Heart disease
  • An irregular heartbeat (arrhythmia)
  • Diabetes
  • A previous case of tuberculosis (TB)
  • Low levels of potassium (hypokalaemia)
  • Pregnant and breastfeeding women as small amounts of Seretide may pass into breast milk; however, pregnant asthmatics must maintain control of asthma

Other Medication Interactions

Some medicines can interfere with the effectiveness of Seretide or cause complications, so it's important to disclose any medication you already take with your doctor. This includes any herbal, recreational or over-the-counter drugs.

Medicine that should not be taken with Seretide are:

  • Beta blockers as these cause the airways to narrow - this includes eye-drop beta blockers for glaucoma.
  • Diuretics, other preventative or reliever medications, or Xanthine derivatives without medical advice as in combination they may adversely affect potassium levels.
  • Azole antifungals, macrolide antibiotics, protease inhibitors for HIV and telaprevir as these increase the amount of active ingredients in your body and increase the risk of side effects.
