G Salbutamol 4 mg Tablet

Short-acting bronchodilator (reliever) for:

• Relief of wheezing and breathlessness in asthma and COPD
• Prevention of exercise- or allergen-induced bronchospasm
• Nebuliser: severe acute asthma attacks
• Tablets/syrup: when inhalers cannot be used (less preferred)

Inhaler (100 mcg/puff): adults and children — 1–2 puffs as needed for symptoms, up to 4 times daily; before exercise 2 puffs. In an attack, more puffs may be needed on medical advice.

Nebuliser: adults 2.5–5 mg up to 4 times daily (more often in severe attacks under supervision); children 2.5 mg.

Tablets/syrup: adults 2–4 mg three or four times daily; children 2–6 years 1–2 mg, 6–12 years 2 mg three or four times daily.

• Use a spacer with the inhaler for better delivery, especially in children.
• If you need your reliever more than 2–3 times a week, see your doctor — asthma control may need a preventer.

• Allergy to salbutamol
• Oral forms: threatened miscarriage or to delay premature labour (not recommended)

Common: shaky hands (tremor), headache, fast heartbeat, palpitations, nervousness.

Less common: muscle cramps, mouth/throat irritation.

Rare: low potassium (high doses), irregular heartbeat, paradoxical bronchospasm (wheeze worsens right after use — stop and use another reliever, seek help), allergic reactions.

• Use with caution in heart disease, high blood pressure, overactive thyroid, diabetes (blood sugar may rise).
• High doses with steroids, diuretics or theophylline can lower potassium.
• Seek urgent help if the reliever is not working as well as usual.

Inhaled salbutamol is safe to use in pregnancy and breastfeeding to control asthma.

• Non-selective beta-blockers such as propranolol (block its effect, may trigger asthma)
• Diuretics, steroids, theophylline (low potassium)
• MAO inhibitors, tricyclic antidepressants (heart effects)
• Digoxin (low potassium raises toxicity)

Fast heartbeat, tremor, agitation, low potassium, high blood sugar, chest pain. Seek medical care.

Store below 30°C. Do not puncture or burn the inhaler canister, even when empty. Protect nebuliser solution from light.
