What Is Foracort Inhaler 6/400 Mcg?

Composition — What Does Foracort Inhaler 6/400 Contain?

• Budesonide (400 mcg): A potent inhaled corticosteroid that binds to glucocorticoid receptors within the cells lining the airways. It blocks the biosynthesis of pro-inflammatory cytokines, prostaglandins, and leukotrienes — the chemical messengers that trigger airway swelling, mucus hypersecretion, and hyperresponsiveness. At 400 mcg per dose, this is the high-strength corticosteroid formulation in the Foracort range, reserved for patients with persistent moderate-to-severe airway inflammation.
• Formoterol Fumarate (6 mcg): A fast-acting, long-acting beta-2 adrenergic agonist (LABA) that stimulates beta-2 receptors on bronchial smooth muscle cells, triggering cyclic AMP production and subsequent smooth muscle relaxation. This widens (dilates) the constricted airways within 1–3 minutes of inhalation — faster than other LABAs such as Salmeterol — and sustains bronchodilation for up to 12 hours.

What Is Foracort Inhaler 6/400 Mcg Used For?

• Moderate-to-Severe Persistent Asthma: For adult and adolescent patients (12 years and older) whose asthma is not adequately controlled on a lower-dose combination inhaler or an inhaled corticosteroid alone. The 400 mcg Budesonide dose provides a substantially stronger anti-inflammatory effect than the Foracort 100 or Foracort 200 formulations.
• Chronic Obstructive Pulmonary Disease (COPD): Long-term maintenance treatment of airflow obstruction in COPD, including chronic bronchitis and emphysema. Reduces the frequency, severity, and duration of COPD exacerbations and improves overall spirometric lung function (FEV1).
• Exercise-Induced Bronchospasm (EIB): When taken before physical activity, the Formoterol component provides rapid pre-emptive bronchodilation, reducing the likelihood of exercise-triggered airway narrowing.
• Step-Up Therapy in Uncontrolled Asthma: Prescribed when patients on lower-dose combination inhalers — such as Foracort 200 or Seroflo 250 — require escalation due to worsening daytime symptoms, increasing rescue inhaler use, or nocturnal awakening.

How to Use Foracort Inhaler 6/400 Mcg Correctly

1. Step 1 — Prime: Before first use, or if the inhaler has not been used for more than 7 days, prime by releasing 2 test sprays into the air (away from the face), shaking for 5 seconds between each spray.
2. Step 2 — Shake: Shake the inhaler vigorously for 5 seconds before each dose.
3. Step 3 — Exhale: Breathe out fully and steadily to empty your lungs as completely as possible.
4. Step 4 — Seal: Place the mouthpiece between your lips and form a tight seal. Do not cover the air vent at the bottom of the inhaler.
5. Step 5 — Inhale & Press: Begin breathing in slowly and deeply through your mouth. At the same time, press the canister down firmly to release one dose. Continue inhaling smoothly to draw the medication deep into the lungs.
6. Step 6 — Hold: Remove the inhaler from your mouth and hold your breath for 10 seconds (or as long as comfortable). This allows the medication to settle on the airway surfaces.
7. Step 7 — Second Puff: If a second inhalation is prescribed, wait 30 seconds, shake again, and repeat Steps 3–6.
8. Step 8 — Rinse: Immediately after use, rinse your mouth thoroughly with water and spit — do not swallow. This is essential to prevent oral thrush (candidiasis), a common side effect of high-dose inhaled corticosteroids.
9. Step 9 — Clean: Wipe the mouthpiece with a dry cloth weekly. Do not wash the metal canister.

Common Side Effects of Foracort Inhaler 6/400 Mcg

• Oral thrush (oropharyngeal candidiasis): Fungal infection in the mouth — significantly reduced by rinsing with water after every use. Higher corticosteroid doses carry a greater risk.
• Hoarseness of voice (dysphonia): Caused by the corticosteroid's local effect on laryngeal muscles. Often mild and dose-dependent.
• Cough or throat irritation: A brief cough immediately after inhalation is common.
• Headache: Typically mild and transient.
• Nausea or vomiting: Uncommon but reported, especially with higher doses.
• Increased heart rate (palpitations): Related to the Formoterol component's beta-adrenergic activity; usually mild at standard doses.
• Muscle tremor: Fine hand tremors, particularly at higher Formoterol doses.
• Low blood potassium (hypokalaemia): Especially with high-dose therapy; your doctor may monitor potassium levels.

• Paradoxical bronchospasm: Sudden worsening of breathing immediately after using the inhaler — discontinue and switch to rescue medication.
• Severe allergic reaction: Skin rash, urticaria, angioedema (facial/throat swelling), or anaphylaxis.
• Signs of adrenal suppression (with prolonged high-dose use): Fatigue, weakness, nausea, dizziness, and low blood pressure — particularly during periods of physical stress, illness, or surgery.
• Worsening eye symptoms: Blurred vision or visual halos — may indicate raised intraocular pressure or cataracts, associated with long-term high-dose corticosteroid use.

Precautions and Warnings Before Using Foracort 6/400 Inhaler

• Cardiovascular disease, arrhythmias, or significant hypertension — Formoterol has mild beta-1 agonist activity that can raise heart rate and blood pressure
• Diabetes mellitus — both Budesonide and Formoterol can elevate blood glucose levels
• Osteoporosis or low bone density — long-term high-dose inhaled corticosteroids can reduce bone mineral density with prolonged use
• Glaucoma or cataracts — associated with long-term corticosteroid exposure
• Active or latent tuberculosis, or untreated fungal or viral respiratory infections
• Thyroid disorders, phaeochromocytoma, or epilepsy (seizure disorders)
• Liver impairment — Budesonide is extensively first-pass metabolised by the liver; systemic exposure is significantly increased in hepatic disease
• Known allergy to Budesonide, Formoterol Fumarate, lactose, or milk protein
