Ventolin Inhaler (Salbutamol)

Ventolin inhaler is a pressurized metered-dose inhaler designed to give a dose of 100 mcg of albuterol which relaxes muscles in the airways and increases air flow to the lungs. It is used to treat or prevent bronchospasm in people with asthma or chronic obstructive pulmonary disease. The bronchodilator works almost straight away to make your breathing easier. It remains effective for about 5 hours.

What is Ventolin inhaler?

Ventolin is a bronchodilator that relaxes the muscles of the airways and increases the flow of air into the patient’s lungs. The drug acts on beta2-receptors, which predominate in the smooth muscles of the bronchi (breathing tubes). The inhaler is used to treat or prevent bronchospasm in people with reversible obstructive respiratory disease. The active ingredient is salbutamol (also known as albuterol). The medicine is intended for use by adults and children older than 4 years.

Indications for use

  • Prevention and relief of bronchospasm in bronchial asthma;
  • Symptomatic treatment of broncho-obstructive syndrome (chronic bronchitis, chronic obstructive pulmonary disease, etc.);
  • Symptomatic treatment of night-time asthma (prolonged tableted forms);
  • Prevention of preterm labor.

Instructions for use

Use Ventolin in dosages recommended by your doctor. Follow all directions given in prescription. Do not use the medicine for longer than recommended.

Shake your inhaler before each use. The usual dose of the drug is 2 inhalations every 4-6 hours. The effect of albuterol can last up to 6 hours. In no case do not increase the dose or frequency of use of the medicine without consulting a doctor.

Each inhalation canister provides 200 inhalations.

Cardiovascular side effects include rapid heartbeat, reflex tachycardia with an increase or decrease in blood pressure. Albuterol in higher doses may exacerbate angina, myocardial ischemia, or cause atrial or ventricular arrhythmias of the heart. The research has not established whether albuterol is dangerous for the fetus or infant. Be sure to notify the doctor if you are pregnant, plan to become pregnant or feed a newborn. It is not known how the drug affects breast milk and whether it can harm the infant. Therefore, you should always consult a doctor before going on breastfeeding while taking albuterol. The drug is not recommended for use by children under 4 years of age. Receiving high doses of salbutamol with asthma exacerbation leads to the fact that each subsequent attack becomes more intense than the previous one. In severe suffocation, the interval between inhalations should be at least 20 minutes. In the absence of a minimal effect from inhalation or the appearance of pronounced tremor, tachycardia, and cardiac arrhythmias, further uncontrolled use of the inhaler is contraindicated. The risk of complications increases with a significant duration of treatment and with abrupt withdrawal of the drug. If a dose of a drug that was previously effective for you is not able to provide relief for your health, this fact is a sign of a serious asthma exacerbation. Before increasing the dose, be sure to consult your doctor. If the medicine gets into your eyes, immediately rinse them with plenty of water. The medication should be stored at room temperature away from moisture, heat, or low temperatures. Keep the inhaler away from open flame or high temperatures, as it is flammable.
