Fostair 100/6 Inhaler

Fostair is a combination inhaler containing two active ingredients: beclometasone dipropionate (a corticosteroid) and formoterol fumarate dihydrate (a long-acting bronchodilator). This pressurised inhalation solution is used for the regular treatment of asthma in adults whose condition is not adequately controlled with inhaled corticosteroids alone, and for symptomatic treatment of severe chronic obstructive pulmonary disease (COPD).

What is Fostair?

Fostair is a pressurised inhalation solution containing two active substances which work together to treat respiratory conditions:

Active Ingredients and Drug Class

  • Beclometasone dipropionate (100 mcg per actuation): A corticosteroid that reduces inflammation and swelling in the airways
  • Formoterol fumarate dihydrate (6 mcg per actuation): A long-acting beta-2 agonist bronchodilator that relaxes airway muscles

Mechanism of Action

Think of Fostair as having two complementary actions: the corticosteroid component (beclometasone) acts like a fire extinguisher that puts out the inflammation in your airways, while the bronchodilator (formoterol) works like a key that unlocks and opens up your constricted breathing passages.

Biological Pathway Explanation

Beclometasone works by entering airway cells and binding to glucocorticoid receptors, which then reduces the production of inflammatory chemicals. Formoterol stimulates beta-2 receptors in the airway smooth muscles, causing relaxation and bronchodilation that lasts for about 12 hours.

What is Fostair Used For?

Approved Indications

ConditionPatient Criteria
Asthma Adults (18+) whose asthma is not adequately controlled with inhaled corticosteroids and "as needed" short-acting bronchodilators, OR those responding well to both corticosteroids and long-acting bronchodilators
COPD Adults (18+) with severe chronic obstructive pulmonary disease (COPD)

Target Patient Populations

Fostair is specifically indicated for adult patients with:

  • Moderate to severe asthma requiring combination therapy
  • Asthma not controlled on inhaled corticosteroids alone
  • Severe COPD (primarily caused by smoking)

⚠️ CRITICAL SAFETY WARNING

If you experience worsening shortness of breath or wheezing immediately after using Fostair (paradoxical bronchospasm), STOP using the inhaler immediately and use your quick-acting "reliever" inhaler. Contact your doctor straightaway as this may indicate a serious reaction requiring alternative treatment.

Before Using Fostair

Medical History Assessment Checklist

Inform your doctor if you have any of the following conditions:

  • Heart problems (angina, recent heart attack, heart failure, coronary heart disease, valvular heart disease, hyperthick obstructive cardiomyopathy)
  • Narrowing of arteries (arteriosclerosis), high blood pressure, or aneurysm
  • Heart rhythm disorders (increased or irregular heart rate, palpitations)
  • Overactive thyroid gland
  • Low blood potassium levels
  • Liver or kidney disease
  • Diabetes
  • Tumour of the adrenal gland (phaeochromocytoma)
  • History of tuberculosis (TB) or chest infections
  • Planned surgery requiring anaesthesia

Required Baseline Tests

Your doctor may recommend:

  • Blood tests to check potassium levels (especially if taking diuretics or if you have severe asthma)
  • Blood glucose monitoring if you have diabetes
  • Electrocardiogram (ECG) if you have heart rhythm concerns

Fostair Contraindications

Absolute Contraindications

  • Hypersensitivity to beclometasone dipropionate, formoterol fumarate dihydrate, or any excipients
  • Children and adolescents under 18 years of age

Relative Contraindications (Use With Caution)

  • Severe cardiovascular disorders

Fostair and Other Medicines

High-Risk Medication Combinations

  • Beta-blockers: Avoid concurrent use (atenolol, propranolol, sotalol, timolol eye drops) as they may reduce Fostair's effectiveness
  • Antiarrhythmics: Quinidine, disopyramide, procainamide may increase risk of heart rhythm disturbances
  • MAOIs and tricyclic antidepressants: May cause changes in heart rhythm and blood pressure
  • Diuretics: May worsen potassium-lowering effects
  • Other bronchodilators: Theophylline, aminophylline may increase risk of side effects
  • HIV medications: Ritonavir, cobicistat may increase Fostair effects requiring careful monitoring

Timing Recommendations

If you need to use eye drops containing beta-blockers for glaucoma, administer them at least 10-15 minutes before using Fostair to minimize interaction.

Pregnancy & Breastfeeding

Pregnancy

Fostair is not recommended during pregnancy unless clearly necessary and only under strict medical supervision. There are no adequate clinical data on use during pregnancy.

Breastfeeding

Avoid using Fostair while breastfeeding unless advised by your doctor, as it is unknown whether the components are excreted in human milk.

Contraception Requirements

Women of childbearing potential should use effective contraception while taking Fostair. Discuss appropriate contraceptive methods with your doctor.

Driving & Machine Operation

Fostair is unlikely to affect your ability to drive and use machines. However, if you experience side effects such as dizziness, trembling, or visual disturbances, you should avoid driving or operating machinery until these symptoms resolve.

Warning Signs to Watch For

  • Dizziness or lightheadedness
  • Trembling or shakiness
  • Blurred vision
  • Palpitations or irregular heartbeat

Fostair Ingredients

Active Ingredients

  • Beclometasone dipropionate: 100 micrograms per actuation

How to Use Fostair

Fostair is for inhalation use only. Always use exactly as prescribed by your doctor.

Step-by-Step Administration

  1. Remove the protective cap from the mouthpiece and check it's clean
  2. Breathe out as slowly and deeply as possible

Fostair (Beclometasone/Formoterol) FAQs

Yes, in some treatment approaches, Fostair can be used both as a maintenance treatment and as a reliever for sudden asthma symptoms. However, this should only be done under specific medical guidance and with appropriate dose limitations (maximum 6 reliever puffs per day).

The bronchodilator effect (formoterol) begins within 1-3 minutes of inhalation, with maximum effect reached in about 1-2 hours. The anti-inflammatory effect (beclometasone) builds up over time with regular use.

No, if you have a known allergy to beclometasone, formoterol, or any of the other ingredients in Fostair, you should not use this medication. Inform your doctor of any inhaler allergies before starting treatment.

Fostair contains a small amount of ethanol (7mg per puff) as part of the formulation. This minimal amount (equivalent to less than 1ml of beer or wine in two puffs) is unlikely to have any noticeable effects and is considered safe for most users.

If you experience paradoxical bronchospasm (worsening breathing immediately after use), stop Fostair immediately, use your quick-acting reliever inhaler, and contact your doctor straightaway as you may need alternative treatment.

No, Fostair is not approved for use in children and adolescents under 18 years of age due to insufficient safety and efficacy data in this population.

The inhaler has a dose counter on the back. Replace when the counter shows 20 and stop using when it shows 0. Do not rely on shaking the canister as this is not an accurate indicator of remaining doses.

Fostair is not recommended during pregnancy unless clearly necessary. There are no adequate clinical data on use during pregnancy, so it should only be used if the potential benefit justifies the potential risk to the fetus.

Fostair contains beclometasone and formoterol, while other common combination inhalers contain different corticosteroids (like fluticasone or budesonide) and different long-acting bronchodilators (like salmeterol or vilanterol). The specific combination and delivery system may work better for some individuals.

No, do not stop or reduce your Fostair dose without consulting your doctor, even if you feel better. Asthma and COPD require ongoing management, and stopping maintenance medication can lead to worsening symptoms and exacerbations.

Clean your inhaler once a week by wiping the inside and outside of the mouthpiece with a clean, dry cloth. Do not use water or other liquids, and never remove the canister from the actuator.

Store below 25°C. Single packs should be used within 3 months of collection from pharmacy. Double packs should be refrigerated before first use, then used within 3 months of opening and stored below 25°C.
