How does this medication work? What will it do for me?
Salbutamol belongs to a class of medications called bronchodilators, and more specifically, β2-adrenergic agonists. This medication is used to treat asthma, chronic bronchitis, and other breathing disorders. It works by relaxing the muscles in the walls of the small airways in the lungs. This helps to open up the airways and make breathing easier.
What form(s) does this medication come in?
Each mL of clear, colourless, orange-flavoured liquid contains 0.4 mg salbutamol. Nonmedicinal ingredients: citric acid monohydrate, ethyl alcohol, hydroxypropyl methylcellulose, orange flavour, purified water, sodium benzoate, sodium citrate dehydrate, and sodium cyclamate.
How should I use this medication?
The usual dose of salbutamol liquid for adults and children over 12 years of age is 5 mL to 10 mL (2 mg to 4 mg) given 3 to 4 times per day.
For children 6 to 12 years of age, the usual dose is 5 mL (2 mg) 3 to 4 times per day. For children 2 to 6 years of age, the usual dose is based on body weight and is given 3 to 4 times per day.
Many things can affect the dose of a medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are taking the medication without consulting your doctor.
Use an oral syringe to measure each dose of the liquid, as it gives a more accurate measurement than household teaspoons.
Salbutamol liquid should not be used for sudden breathing difficulties. For asthma attacks and other sudden breathing problems, a short-acting bronchodilator (e.g., salbutamol, terbutaline) inhaler should be used.
It is important to take this medication exactly as prescribed by your doctor. If you miss a dose, take it as soon as possible and continue with your regular schedule. If it is almost time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one. If you are not sure what to do after missing a dose, contact your doctor or pharmacist for advice.

Are there any other precautions or warnings for this medication?
Asthma control: If your usual dose of this medication no longer seems to work as well or if you are using more of your short-acting bronchodilator inhaler (e.g., salbutamol, terbutaline) than usual, your asthma could be worsening. Contact your doctor if this happens. Do not increase the dose or how often you take this medication without consulting your doctor.

Heart conditions: Salbutamol can cause heart complications when used by people with heart conditions, such as heart disease, abnormal heart rhythms, and high blood pressure. If you have any of these conditions, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Low blood potassium: Salbutamol liquid can cause low potassium levels in the blood.
