What are the warnings and precautions for the use of Aerolin® spray?

The duration of action of salbutamol is 4 to 6 hours in most patients.
The treatment of asthma should be accompanied by an appropriate program, and the patient's response should be clinically monitored by pulmonary function tests.
Patients should not increase the dose or frequency of administration of Aerolin® spray, even if the usual relief does not occur or the duration of action decreases.
The increase in the use of short-acting beta2-adrenergic receptor agonists for symptom relief indicates a deterioration in asthma control.
The therapy with beta2-agonists can result in potentially severe hypokalemia, especially after parenteral or nebulization administration.
Aerolin® spray should be administered with caution in patients with thyrotoxicosis.
Special care is recommended in severe acute asthma, as this effect can be potentiated by concomitant treatment with xanthine derivatives, steroids, and diuretics, as well as hypoxia.
Bronchodilators should not be the only or main treatment for acute or unstable asthma.
Patients with severe asthma have continuous symptoms and constant exacerbations, with limited physical capacity and peak expiratory flow values below 60% of predicted, with greater than 30% variability, and usually do not return to normal after the use of bronchodilators.
Patients should seek medical advice if a previously effective dose of salbutamol does not produce the expected relief for at least 3 hours, so that any necessary additional measures can be taken.
The therapy with Aerolin® spray should be discontinued immediately if bronchospasm paradoxical occurs, and the patient should be reassessed and, if necessary, new treatment instituted.
a. The use of Aerolin® spray is not recommended for pregnant women.
b. Aerolin® spray should not be used in cases of imminent abortion.
c. Patients with thyroid problems should not use Aerolin® spray.
d. Patients with asthma should not use Aerolin® spray.
