Ventolin Adverse Reactions

Adverse events are listed as follows by system organ class and frequency. Frequencies are defined as: Very common (≥1/10), common (≥1/100 to <1/10), uncommon (≥1/1000 to <1/100), rare (≥1/10,000 to <1/1000) and very rare (<1/10,000) including isolated reports. Very common and common events were generally determined from clinical trial data. Rare and very rare events were generally determined from spontaneous data.
Immune system disorders: Very rare: Hypersensitivity reactions including angioedema, urticaria, bronchospasm, hypotension and collapse.
Metabolism and nutrition disorders: Rare: Hypokalaemia.
Potentially serious hypokalaemia may result from beta₂-agonist therapy.
Respirator Solution/Nebule/Infusion: Very rare: Lactic acidosis.
Lactic acidosis has been reported very rarely in patients receiving intravenous and nebulised salbutamol therapy for the treatment of acute asthma exacerbation.
Nervous system disorders: Common: Headache.
Very rare: Hyperactivity.
Syrup/Infusion: Very common: Tremor.
Evohaler/Respirator Solution/Nebule: Common: Tremor.
Cardiac disorders: Common: Tachycardia.
Syrup: Common: palpitations.
Unknown: Myocardial ischaemia* (see Precautions).
*reported spontaneously in post-marketing data therefore frequency regarded as unknown.
Syrup/Infusion: Rare: Cardiac arrhythmias including atrial fibrillation, supraventricular tachycardia and extrasystoles.
Evohaler/Respirator Solution/Nebule: Uncommon: Palpitations.
Very rare: Cardiac arrhythmias including atrial fibrillation, supraventricular tachycardia and extrasystoles.
Infusion: Very common: Tachycardia, palpitations.
Uncommon: Myocardial ischaemia*.
*In the management of pre-term labour with VENTOLIN injection/solution for infusion.
Vascular disorders: Rare: Peripheral vasodilation.
Musculoskeletal and connective tissue disorders: Syrup/Infusion: Common: Muscle cramps.
Syrup: Very rare: Feeling of muscle tension.
Evohaler/Respirator Solution/Nebule: Uncommon: Muscle cramps.
Respiratory, thoracic and mediastinal disorders: Evohaler/Respirator Solution/Nebule: Very rare: Paradoxical bronchospasm.
Infusion: Uncommon: Pulmonary oedema.
In the management of pre-term labour, VENTOLIN injection and solution for intravenous infusion has uncommonly been associated with pulmonary oedema. Patients with predisposing factors including multiple pregnancies, fluid overload, maternal infection and pre-eclampsia may have an increased risk of developing pulmonary oedema.
Gastrointestinal disorders: Evohaler/Respirator Solution/Nebule: Uncommon: Mouth and throat irritation.
Infusion: Very rare: Nausea and vomiting.
In the management of premature labour, intravenous infusion of VENTOLIN has very rarely been associated with nausea and vomiting.
Injury, poisoning and procedural complications: Infusion: Very rare: Slight pain or stinging on intramuscular use of undiluted injection.
