    Ventolin HFA General Information

    ventolin_bVentolin is a drug that belongs to bronchodilators and is used to treat airway diseases and breathing disorders, such as asthma, chronic bronchitis, bronchospasm, and others. It aims to increase air flowing to the lungs thus relaxing the airway muscles and helping breathe easier.

    Before using Ventolin, consult your doctor and make sure you tell him/her about the following conditions you may have if any:

    • You have an allergy to albuterol;
    • You have suffered from heart disease;
    • You have high blood pressure, epilepsy, or heart rhythm disorder;
    • You suffer from diabetes;
    • You are pregnant or planning to become pregnant;
    • You are breastfeeding.

    Moreover, you should inform your doctor on any treatment, or intake of any drug, vitamin complex, herbal medicine, or supplements.

    Pay special attention to the following pharmaceuticals:

    • Monoamine oxidase inhibitors
    • Other inhalers or asthma medicines
    • Diuretics
    • Beta-blocker medicines
    • Tricyclic antidepressants

    Ventolin may come under numerous brand names and can be delivered in different forms, such as a respirator solution, isotonic solution, blisters, and inhalation aerosols.


    Ventolin HFA Inhaler Uses

    Use Ventolin as instructed in the Patient Information leaflet unless otherwise is directed by your health provider. Do not use it more often or less often than prescribed, as the dosage is dependent on your particular case of disease and your body’s response to treatment. Even if the medicine no longer alleviates your symptoms, do not change the dosage on your own without first consulting your doctor.

    An average dose to help asthma symptoms is 1 to 2 inhalations for people ≥ 12, and 1 inhalation for children under 11. For more severe attacks, more inhalations may be recommended. Inhale Ventolin by mouth every 4 to 6 hours, unless otherwise is prescribed by your health provider. When it comes to long-term management of asthma, the dose is 1 to 2 inhalations made 4 times per day. Do not exceed the daily dose of 8 inhalations for adults and 4 inhalations for children.

    To prevent exercise-induced asthma, inhale 2 puffs approximately half an hour before exercise. For children, the usual dose is 1 puff before exercise.

    If you are prescribed with two inhalations, wait 1 minute between puffs. In case you are using other inhalers, wait 1 minute between inhalation of each spray.

    For patients prescribed with a nebulizer solution, the usual dose is 2.5 mg to 5.0 mg administered 4 times a day. For children under 12, the usual dose is 2.5 mg taken not more than 4 times per day.

    Ventolin HFA Precautions

    Before you start using Ventolin, inform your care provider if you are allergic to albuterol or other components. Make sure you also report on any possible side effects or serious reactions you may have had to such pharmaceuticals as terbutaline, metaproterenol or levalbuterol. Such conditions as pregnancy, current breastfeeding, heart problems, or blood pressure issues may also affect your medicine plan.

    Since this drug may cause light dizziness, avoid driving a car, operating machinery, or performing other activities requiring quick reaction and alertness.

    When the prescribed dosage of Ventolin no longer helps asthma symptoms, do not increase the dose on your own as you may worsen your asthma case. Consult your doctor regarding the necessary dose change or using another inhaler.

    Long-term intake of albuterol may increase blood sugar levels, so patients with diabetes should discuss their condition and the appropriate medical schedule with their doctor. A special monitoring may be recommended to control the condition and detect possible side effects, if any.

    In some patients, albuterol can cause difficulty breathing or abnormal heart rhythms.  If you notice any symptoms, stop using the medication and check with your doctor immediately. Some people may also experience low blood potassium, seizures, or overactive thyroid. Should you notice any deviation from your usual health condition, inform your doctor straight away.

    All children should take Ventolin under supervision by an adult after consulting a physician.

    The conducted studies suggest that albuterol is normally well-tolerated, and rarely causes severe adverse effects. However, at least 1% patients have reported on changes in heart rate caused by administration of 0.18 mg of albuterol by a metered-dose inhaler. Since albuterol in some cases may produce tachycardia, it can aggravate angina.

    The following complications associated with albuterol have been reported by not more than 1% patients:

    • Atrial fibrillation
    • Supraventricular ectopic beats
    • Ventricular tachycardia and reflex tachycardia
    • Palpitations
    • Peripheral vasodilatation
    • Atrial or ventricular arrhythmias
    • Pulmonary edema
    • Tremors
    • Intracellular shift of potassium
    • Transient lactic acidosis
    • Hypokalemia
    • Hyperglycemia and lactic acidosis
    • Diabetic ketoacidosis
    • Paradoxical bronchospasm

    These data however do not mean every patient taking Ventolin will suffer from the above complications. The onset of symptoms related to these conditions is very rare, and if any of them occur, consult your doctor immediately. You may be advised to change the medication, dosage or route of administration.
