Clenil Aerosol 800mcg/2ml – Beclomethasone Inhaled Steroid for Asthma

Drug Class: Inhaled Corticosteroid (ICS) | Form: Solution for Nebulisation (Unit Dose Vial — UDV) | Prescription Status: Prescription Only (Rx)

What Is Clenil Aerosol 800mcg?

Clenil for Aerosol (800mcg/2ml) is a prescription inhaled corticosteroid delivered as a unit dose vial (UDV) for use with a nebuliser. Each 2ml vial contains Beclomethasone Dipropionate 800mcg — a potent synthetic corticosteroid that reduces and controls chronic inflammation in the airways, addressing the underlying cause of asthma rather than simply relieving symptoms in the moment.

Unlike bronchodilators such as Salbutamol that open the airways rapidly during an acute attack, Clenil is a preventer medication — it works by consistently suppressing airway inflammation over time, reducing the frequency and severity of asthma attacks, decreasing airway hypersensitivity to triggers, and improving long-term lung function. The nebulised form makes Clenil particularly suitable for patients who cannot use pressurised inhalers effectively — including young children, elderly patients, and those with severe breathlessness who lack the coordination or inspiratory effort required for metered dose inhalers.

Clenil must be used regularly as prescribed — its benefits build over days to weeks of consistent use and it is not intended for immediate relief of acute breathlessness.

What Is Clenil Aerosol 800mcg Used For?

Clenil Aerosol is prescribed for:

• Severe persistent asthma (دمہ) — long-term control of severe asthma where high-dose inhaled corticosteroid therapy is required to maintain symptom control and prevent frequent exacerbations
• Moderate to severe asthma in patients requiring nebulised therapy — patients unable to use standard inhalers effectively, including young children and the severely breathless
• Chronic obstructive bronchopathy with asthmatic component — chronic airway disease with significant reversible inflammatory and bronchospastic features that respond to corticosteroid treatment
• Step-up asthma management — escalation of inhaled corticosteroid dose when lower doses have failed to achieve adequate asthma control
• Reduction of systemic steroid dependence — transitioning patients from long-term oral corticosteroids to high-dose inhaled therapy to minimise systemic steroid side effects under specialist supervision

Clenil is a preventer — it must be used regularly every day. It does not provide immediate relief during an acute asthma attack. Always keep a fast-acting bronchodilator (such as Salbutamol) available for acute symptom relief.

How Does Clenil Aerosol Work?

Beclomethasone Dipropionate 800mcg — Inhaled Corticosteroid: Beclomethasone Dipropionate is a synthetic corticosteroid that, when inhaled, acts directly on the inflammatory cells and mediators within the airway mucosa. It works by binding to intracellular glucocorticoid receptors in the cells lining the airways — activating anti-inflammatory genes while suppressing the genes responsible for producing inflammatory cytokines, chemokines, and other mediators that drive chronic airway inflammation in asthma.

The result of consistent daily use is a progressive reduction in airway inflammation, decreased mucus hypersecretion, reduced airway hyperresponsiveness to triggers such as exercise, cold air, and allergens, and gradual improvement in airway calibre and lung function. These changes develop over days to weeks of regular use — which is why Clenil must be taken every day regardless of whether symptoms are present.

Why Nebulised Delivery Matters: Nebulisation converts the liquid Beclomethasone solution into a fine aerosol mist that is inhaled slowly and deeply over several minutes — allowing the drug to deposit throughout the entire airway, including smaller peripheral airways that pressurised inhalers may not reach as effectively. This makes nebulised Beclomethasone particularly valuable for severe asthma, very young children, and patients with significantly impaired lung function.

Preventer vs. Reliever — A Critical Distinction: Clenil addresses the cause of asthma symptoms — chronic airway inflammation — rather than the immediate consequence — bronchospasm. Regular use reduces the underlying inflammatory state of the airways so that triggers cause less severe reactions and acute attacks occur less frequently. It does not relax airway smooth muscle or provide the rapid bronchodilation needed during an acute attack — a fast-acting reliever such as Salbutamol must always be kept available alongside Clenil therapy.

Dosage and Administration

⚠️ Use exactly as prescribed. Never stop Clenil suddenly without medical advice — dose must be tapered under doctor supervision. Always rinse mouth and throat with water after nebulisation. Keep reliever inhaler available at all times for acute attacks.

How to Use with a Nebuliser:

1. Wash hands thoroughly before handling the vial and nebuliser
2. Twist and open one UDV vial — use the entire 2ml contents
3. Pour the vial contents into the nebuliser chamber
4. Attach the mouthpiece or face mask as appropriate — face mask recommended for young children
5. Switch on the nebuliser and breathe slowly and deeply through the mouth until the chamber is empty — typically 5 to 10 minutes
6. Immediately after nebulisation, rinse the mouth and throat thoroughly with water and spit out — this removes deposited Beclomethasone from the oropharynx and prevents oral thrush (fungal infection)
7. Clean the nebuliser chamber and mask after every use according to the manufacturer's instructions

Active Ingredients

Who Should NOT Use Clenil Aerosol?

Do not use Clenil if you:

• Are allergic to Beclomethasone Dipropionate or any ingredient in this product
• Are experiencing an acute asthma attack — Clenil will not provide immediate relief; use a fast-acting bronchodilator and seek medical attention
• Have active untreated respiratory tuberculosis — corticosteroids suppress immune response and can worsen TB

Always consult your doctor before use if you:

• Have active respiratory infection — bacterial, viral, or fungal lung infections require treatment before or alongside corticosteroid therapy
• Are being transferred from oral corticosteroids to inhaled therapy — this transition requires careful medical supervision as adrenal insufficiency can develop
• Have diabetes — inhaled corticosteroids at high doses can affect blood glucose control
• Are pregnant or breastfeeding — use only when benefit clearly outweighs risk as assessed by your doctor
• Have thyroid disease, osteoporosis, or glaucoma — high-dose inhaled corticosteroids can have systemic effects with prolonged use

Side Effects

Common (local — related to airway deposition):

• Oral thrush (منہ میں فنگل انفیکشن) — fungal infection of the mouth and throat caused by Beclomethasone depositing on oral mucosa — prevented almost completely by rinsing mouth with water immediately after every nebulisation
• Hoarseness or mild voice changes — caused by steroid deposition on vocal cords
• Mild throat irritation or cough immediately after nebulisation

Serious — Consult Your Doctor:

• Adrenal suppression — with high-dose or prolonged use, inhaled corticosteroids can suppress the adrenal glands' ability to produce natural cortisol — patients transferring from oral steroids are at particular risk; never stop Clenil suddenly
• Growth effects in children — prolonged high-dose inhaled corticosteroid use may slow growth velocity in children; regular height monitoring is recommended
• Paradoxical bronchospasm — rare but important: if breathing worsens immediately after nebulisation rather than improving, stop use and contact your doctor immediately — this indicates bronchospasm triggered by the inhaled medication
• Systemic corticosteroid effects with prolonged high-dose use — bone density reduction, cataracts, raised blood pressure, blood glucose elevation — risk is lower with inhaled than oral steroids but not absent at high doses
• Severe allergic reaction — rash, swelling, difficulty breathing (یہ طبی ہنگامی صورتحال ہے)

Frequently Asked Questions

Clenil does not relieve my breathlessness during an attack — is it working?

Yes — Clenil is working correctly if used regularly, but it is not designed to relieve acute breathlessness. It is a preventer medication that reduces the underlying airway inflammation responsible for asthma over time — not a bronchodilator that opens airways immediately during an attack. For acute breathlessness, you must use your fast-acting reliever inhaler such as Salbutamol. If you are using your reliever more than twice a week, this indicates your asthma is not well controlled and your doctor should review your preventer therapy. Regular daily use of Clenil should reduce how often you need your reliever over weeks of consistent treatment.

Why is rinsing my mouth after nebulisation so important?

Rinsing the mouth and throat with water immediately after every Clenil nebulisation is one of the most important steps in the administration process. During nebulisation, a proportion of the Beclomethasone deposits on the mouth, throat, and vocal cords rather than reaching the lungs. This deposited steroid can cause oral thrush — a fungal infection presenting as white patches in the mouth — and hoarseness of the voice. Thorough rinsing with water and spitting out removes the deposited drug before it can cause local side effects. This simple step prevents oral thrush in the vast majority of patients.

Can I stop using Clenil when my asthma feels better?

No — this is one of the most important things to understand about preventer therapy. Asthma feeling better is a sign that Clenil is working — not a sign that it is no longer needed. Stopping Clenil suddenly removes the anti-inflammatory protection that is keeping your airways calm and your symptoms controlled. Airway inflammation will gradually return, asthma symptoms will worsen, and you may experience a serious exacerbation. Always continue Clenil as prescribed and only reduce or stop under your doctor's specific instruction with a planned tapering schedule.

Why is the nebulised form used instead of a standard inhaler?

Nebulised Beclomethasone is prescribed when standard pressurised metered dose inhalers (pMDIs) or dry powder inhalers cannot be used effectively. This includes young children who cannot coordinate breath-actuation with a pMDI, elderly patients with limited hand strength or coordination, and patients during severe exacerbations who lack the inspiratory force to use dry powder inhalers. Nebulisation requires only normal tidal breathing — making it accessible to all patient groups regardless of coordination ability or lung function severity.

Is high-dose inhaled corticosteroid safe — I thought steroids cause serious side effects?

Inhaled corticosteroids like Beclomethasone carry significantly lower systemic side effect risk than oral or injected steroids because they act locally in the airways and very little is absorbed into the bloodstream. The 800mcg dose in Clenil is considered high-dose inhaled therapy and is reserved for severe asthma where the benefit of controlling dangerous airway inflammation clearly outweighs the low but real risk of systemic effects. Your doctor will use the lowest dose that achieves adequate asthma control and will monitor for systemic effects with regular review. Uncontrolled severe asthma carries far greater health risk than appropriately supervised high-dose inhaled corticosteroid therapy.
