Common use

Proventil (albuterol) is a fast-acting bronchodilator that belongs to the class of medications known as beta-2 adrenergic agonists. This rescue inhaler works by relaxing the smooth muscles in the airways and rapidly increasing air flow to the lungs, providing quick breathing relief when you need it most.

Proventil is used to treat or prevent bronchospasm in people with reversible obstructive airway disease, including asthma and chronic obstructive pulmonary disease (COPD). As a trusted asthma inhaler, albuterol provides rapid relief from wheezing, shortness of breath, chest tightness, and coughing caused by airway constriction. Proventil is also commonly used to prevent exercise-induced bronchospasm, allowing individuals with asthma to maintain an active lifestyle. Whether you are managing acute asthma symptoms or preparing for physical activity, this bronchodilator delivers reliable, fast-acting respiratory support.



Dosage and direction

Use Proventil exactly as it was prescribed for you. The typical dose for adults and children over 4 years is 1-2 inhalations every 4 to 6 hours as needed for breathing relief. Do not use the medication in larger amounts, or use it for longer than recommended by your doctor. If you find that you need to use your rescue inhaler more frequently than usual, this may indicate that your asthma is not well controlled, and you should consult your doctor about adjusting your treatment plan.

For preventing exercise-induced bronchospasm, use 2 inhalations approximately 15-30 minutes before exercise. Shake the inhaler well before each use to ensure proper medication delivery. Breathe out fully, place the mouthpiece in your mouth, press down on the canister while breathing in slowly and deeply, then hold your breath for about 10 seconds before exhaling.



Precautions

When using the Proventil inhaler device for the first time, prime it by spraying 4 test sprays into the air, away from your face. Shake well before priming. Also prime the inhaler if you have not used it for 2 weeks or longer, or if you have dropped the inhaler. Proper priming ensures you receive the correct dose of albuterol with each use.

Keep track of how many inhalations you have used so you know when the canister is running low. Having a backup rescue inhaler available is recommended, especially for individuals who rely on their bronchodilator for managing acute bronchospasm episodes. Clean your inhaler mouthpiece regularly as directed in the product instructions to prevent medication buildup and ensure optimal delivery.



Contraindications

You should not use Proventil if you are allergic to albuterol (salbutamol) or any of the inactive ingredients in the formulation.

If you have certain conditions, you may need a dose adjustment or special tests to safely use this medication. Before using Proventil, tell your doctor if you have:

heart disease, high blood pressure, or congestive heart failure;

a heart rhythm disorder or irregular heartbeat;

a seizure disorder such as epilepsy;

diabetes (albuterol may affect blood sugar levels);

overactive thyroid (hyperthyroidism); or

low potassium levels in your blood.

Tell your doctor if you are pregnant or plan to become pregnant during treatment. It is not known whether albuterol passes into breast milk or if it could harm a nursing baby. Discuss the risks and benefits with your healthcare provider.



Possible side effects

Stop using Proventil and get emergency medical help if you have any of these signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat. Call your doctor at once if you have a serious side effect such as:

paradoxical bronchospasm (wheezing, chest tightness, trouble breathing), especially after starting a new canister of this medicine;

chest pain and fast, pounding, or uneven heart beats;

tremor, nervousness, or restlessness;

low potassium (confusion, uneven heart rate, extreme thirst, increased urination, leg discomfort, muscle weakness or limp feeling); or

dangerously high blood pressure (severe headache, blurred vision, buzzing in your ears, anxiety, confusion, chest pain, shortness of breath, uneven heartbeats, seizure).

Less serious Proventil side effects may include:

headache, dizziness, nervousness;

sleep problems (insomnia);

cough, hoarseness, sore throat, runny or stuffy nose;

dry mouth and throat;

muscle pain or mild tremor; or

diarrhea, nausea.

These milder side effects typically diminish as your body adjusts to the albuterol medication. If they persist or worsen, contact your healthcare provider for guidance.



Drug interaction

Before using this bronchodilator medication, tell your doctor if you are taking any of the following medicines:

a diuretic (water pill), which may increase the risk of low potassium;

digoxin (digitalis, Lanoxin);

a beta-blocker such as atenolol (Tenormin), metoprolol (Lopressor), propranolol (Inderal), and others — these may reduce the effectiveness of albuterol;

an antidepressant such as amitriptyline (Elavil, Etrafon), doxepin (Sinequan), imipramine (Janimine, Tofranil), nortriptyline (Pamelor), and others;

an MAO inhibitor such as isocarboxazid (Marplan), phenelzine (Nardil), rasagiline (Azilect), selegiline (Eldepryl, Emsam), or tranylcypromine (Parnate); or

other bronchodilators such as levalbuterol (Xopenex), pirbuterol (Maxair), terbutaline (Brethine), salmeterol (Serevent), metaproterenol (Alupent), or isoproterenol (Isuprel).

Tell your doctor about all the prescription and over-the-counter medications you use. This includes vitamins, minerals, herbal products, and drugs prescribed by other doctors. Complete medication disclosure helps prevent potentially harmful drug interactions.



Missed dose

Use the medication as soon as you remember. If it is almost time for the next dose, skip the missed dose and use the medicine at the next regularly scheduled time. Do not use extra medicine to make up the missed dose. If you use Proventil only as a rescue inhaler on an as-needed basis, there is no regular dosing schedule to follow.



Overdose

Seek emergency medical attention if you think you have used too much of this medicine. An overdose of albuterol can be serious and potentially fatal. Overdose symptoms may include nervousness, headache, tremor, dry mouth, chest pain or heavy feeling, rapid or uneven heart rate, pain spreading to the arm or shoulder, nausea, sweating, dizziness, seizure (convulsions), feeling light-headed or fainting. Contact your local poison control center immediately if you suspect an overdose.



Storage

Store Proventil at room temperature away from moisture and heat. Extreme heat can cause the medicine canister to burst. Do not store it in your car on hot days or expose it to temperatures above 120 degrees F (49 degrees C). Do not throw an empty canister into open flame. Keep your asthma inhaler away from children and ensure the protective cap is in place when not in use.
