Albuterol hfa 90mcg (9gm) aer?

Albuterol HFA 90 µg per actuation (aerosol)

Why it’s used

• Acute asthma relief – “rescue” inhaler for sudden wheeze, shortness of breath, chest tightness, or cough.
• Bronchospasm from COPD – used similarly to relieve sudden bronchoconstriction.
• Exercise‑induced bronchoconstriction – taken before physical activity (usually 4–10 min beforehand).

Typical dosing

Important: “Puff” refers to a single actuation of the inhaler. If you’re unsure of your technique, ask a pharmacist or nurse to demonstrate the proper method.

How to use it correctly

1. Shake the inhaler well (about 5–10 shakes).
2. Remove the cap and prime the inhaler (if it’s the first use or you haven’t used it in a while): press the nozzle 3–5 times.
3. Inhale slowly and deeply while pressing the inhaler once.
4. Hold your breath for ~10 s, then exhale slowly.
5. If another puff is needed, wait about 30–60 s before repeating.

• Spacers: If you have trouble coordinating inhalation, a spacer or valved holding chamber can improve drug delivery and reduce side effects.
• Cleaning: Keep the inhaler and spacer clean; replace the propellant cartridge every 3–4 years (or as per manufacturer).
• Storage: Keep at room temperature (20–25 °C) and avoid freezing or high heat.

Common side effects

These usually subside after 1–3 days of use. If symptoms persist or worsen, contact your clinician.

Precautions & contraindications

• Heart disease: Use with caution in patients with coronary artery disease, arrhythmias, or uncontrolled hypertension.
• Hypokalemia: Albuterol can cause potassium shifts; monitor potassium if you’re on diuretics or have kidney disease.
• Hyperthyroidism: May worsen tachycardia.
• Pregnancy: Generally considered safe in the short term; use under medical advice if needed.
• Children: Use only as directed; the dosing range (1–2 puffs) is also valid for children ≥ 6 years but may be adjusted by a pediatrician.

Drug interactions

When to seek medical help

• Severe shortness of breath or wheezing that doesn’t improve after 2–4 puffs.
• Chest pain, palpitations, or rapid heartbeat that lasts > 15 min.
• Signs of an allergic reaction (rash, itching, swelling, dizziness, difficulty breathing).
• Excessive tremor or anxiety that interferes with daily life.
