There may develop but very rarely hypersensitivity reactions:

• angioedema;
• urticaria;
• bronchospasm;
• hypotension;
• collapse;
• muscle cramps;
• tachycardia.

Inhaled medicines may cause paradoxical bronchospasm. Paradoxical bronchospasm should be immediately arrested with a different formulation of Ventolin inhaler or another fast-acting bronchodilator. You should immediately discontinue Ventolin use, estimate patient’s condition, conduct necessary examinations and medical screenings and prescribe appropriate treatment. Inhaled medicines may cause oral mucosa and pharynx irritation.

Therapy with agonists beta 2-adrenergic receptors can sometimes cause hypokalemia, which may cause serious danger to the patient. Like other beta 2-adrenergic agonists, salbutamol can sometimes cause mental excitement and increase motor activity in children.

In patients with a predisposition to arrhythmia development salbutamol may cause cardiac arrhythmia, including:

• atrial fibrillation;
• supraventricular tachycardia;
• extrasystoles.
  

Contraindications

There are four main contraindicated points while taking Ventolin. Be attentive and read the article to get to know more about these aspects.
They are:

1. hypersensitivity to any drug component;
2. children up to six years;
3. chronic heart failure, arterial hypertension, thyrotoxicosis, tachyarrhythmia, pheochromocytoma;

Special Instructions

Increasing demand for inhaled b2-adrenergic agonists use with short action duration for asthma symptoms control indicates disease exacerbation. In such cases, you should overview patient’s treatment plan. Sudden and progressive asthma deterioration can become a threat to the patient’s life, so in such cases, it is necessary to urgently address the issue of appointment or increasing corticosteroids doses. Such patients are recommended to carry out daily monitoring of peak expiratory flow rate.

Very high doses can lead to adverse reactions development, so to solve the issue of dose increasing or drug use frequency can only be made by a doctor. Patients who use this inhaler at home, it is necessary to warn that if usual dose action becomes less effective or less long, you can not independently increase the dose or administration frequency, but should seek for medical advice immediately. Ventolin should be used with caution in patients who have received high doses of another sympathomimetic.

Salbutamol should be used with caution in patients with thyrotoxicosis.

Therapy b2-adrenoreceptor agonists, particularly when administered parenterally or by means of nebulizer can result in hypokalemia. It is advised to exercise special care when treating severe asthma attacks, since in these cases, hypokalemia may be enhanced by simultaneous use of:

• xanthine derivatives;
• corticosteroids;
• diuretics;
• hypoxia.

In such situations, it is necessary to control potassium level in blood serum.
