Proventil aerosol contains a microcrystalline suspension of albuterol sulfate, ethanol, and oleic acid.
Proventil is a bronchodilator that relaxes the muscles of the respiratory tract and increases the flow of air into the patient’s lungs. The substance predominantly acts on beta2-receptors in the smooth muscles of the bronchi (breathing tubes).
The drug is used to treat or prevent bronchospasm in people with reversible obstructive respiratory disease.
- Use albuterol in dosages recommended by your doctor. Follow all recipe directions;
- Do not use the medicine for longer than recommended;
- Before each use of the drug, shake your inhaler;
- The usual dose of albuterol is 2 inhalations every 4 to 6 hours. In this case, the effect lasts about 4 to 6 hours;
- 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 highly flammable;
- If the medicine gets into your eyes, rinse them with plenty of water immediately;
- Patients with cardiovascular disorders (especially coronary insufficiency), cardiac arrhythmias and hypertension, convulsive disorders should use albuterol with caution and only in cases agreed with the attending physician;
- The effect of albuterol solution for inhalation can last up to six hours and therefore should not be used more often than recommended;
- Never increase the dose or frequency of use of the drug without consulting a doctor;
- Proventil should not be combined with other medicines for asthma unless otherwise recommended by a doctor.
It is safe to use Proventil 4-6 times per day. But if you are having an attack, you can make inhalations every 30-60 minutes for 2-3 hours without significant risk of side effects.
The medication is generally well tolerated by patients, and all side effects are quite consistent with its pharmacological activity.
Proventil can cause the following allergic reactions:
- shortness of breath, choking, or other breathing problems;
- chest pain, fast heart rate;
- pain or burning when urinating;
- high blood sugar – increased thirst, frequent urination, hunger, dry mouth, sweet smell when breathing, drowsiness, dry skin, blurred vision, weight loss;

- increased body temperature;
- redness of the face, neck, upper chest;
- urination problem;
- trouble sleeping;
In general, the severity of these side effects depends on the dose. With further treatment, some side effects may pass by themselves, as your body adapts to the drug.

Albuterol in higher doses may exacerbate angina, myocardial ischemia, or cause atrial or ventricular arrhythmias of the heart.
Overdose symptoms may include dry mouth, tremor, chest pain, fast heartbeat, nausea, general feeling of sickness, convulsions, feeling of weakness or fainting.
Receiving high doses of salbutamol with asthma exacerbation leads to the fact that each subsequent attack of asphyxiation becomes more intense than the previous one.
