What is Ventolin?

Ventolin is a bronchodilator that relaxes muscles in the airways and increases air flow to the lungs. In the United States, Ventolin is available only as Ventolin HFA, a metered-dose inhaler delivering 90 mcg of albuterol sulfate per actuation; all other Ventolin formulations, including the tablets, syrup, nebulizer solutions, and Rotacaps, have been discontinued. Generic albuterol formulations are still available.

Ventolin HFA is used to treat or prevent bronchospasm, or narrowing of the airways in the lungs, in people with asthma or certain types of chronic obstructive pulmonary disease (COPD). It is also used to prevent exercise-induced bronchospasm.

Ventolin HFA is not approved for use by anyone younger than 4 years old

Warnings

It is important to keep Ventolin on hand at all times. Get your prescription refilled before you run out of medicine completely. Keep using all of your other medications as prescribed by your doctor.

Talk with your doctor if any of your asthma medications do not seem to work as well in treating or preventing attacks. If it seems like you need to use more of any of your medications in a 24-hour period, talk with your doctor. An increased need for medication could be an early sign of a serious asthma attack.

Only use Ventolin as prescribed by your physician. An overdose of albuterol can be fatal. Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.

Extreme heat can cause the Ventolin HFA canister to burst. Do not store your inhaler in your car on hot days. Do not throw an empty canister into an open flame.

Follow all directions on your medicine label and package. Tell each of your healthcare providers about all your medical conditions, allergies, and all medicines you use.

Before taking this medicine

You should not use Ventolin if you are allergic to albuterol.

Ventolin inhaler is not approved for use by anyone younger than 4 years old.

To make sure this medicine is safe for you, tell your doctor if you have:

  • heart disease, high blood pressure;
  • a thyroid disorder;
  • seizures;
  • diabetes; or
  • low levels of potassium in your blood.

Tell your doctor if you are pregnant or plan to become pregnant. It is not known whether albuterol will harm an unborn baby. However, having uncontrolled asthma during pregnancy may increase the risk of premature birth, low birth weight, or eclampsia (dangerously high blood pressure that can lead to medical problems in both mother and baby). The benefit of preventing bronchospasm may outweigh any risks to the baby.

If you are pregnant, your name may be listed on a pregnancy registry to track the effects of albuterol on the baby.

It may not be safe to breastfeed while using Ventolin HFA. Ask your doctor about any risk.

How should I use Ventolin?

Use Ventolin exactly as prescribed by your doctor. Follow all directions on your prescription label and read all medication guides.

Read and carefully follow any Instructions for Use provided with your medicine. Ask your doctor or pharmacist if you do not understand these instructions.

Do not allow a young child to use Ventolin without help from an adult.

To prevent exercise-induced bronchospasm, use this medicine 15 to 30 minutes before you exercise. The effects of Ventolin should last about 4 to 6 hours.

Seek medical attention if your breathing problems get worse quickly, or if you think your asthma medications are not working as well.

Ventolin HFA must be shaken well before each use.

Always use the new inhaler device provided with your refill. Do not float a medicine canister in water to see if it is empty.

Your dose needs may change due to surgery, illness, stress, or a recent asthma attack. Do not change your dose or dosing schedule without your doctor's advice.

Store at room temperature away from moisture, heat, or cold temperatures.

Store Ventolin HFA with the mouthpiece down.

Keep the inhaler canister away from open flame or high heat. The canister may explode if it gets too hot. Do not puncture or burn an empty inhaler canister.

What happens if I miss a dose?

Ventolin should be used only when needed. Use the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not use extra medicine to make up the missed dose.

Get your prescription refilled before you run out of medicine completely.

How to use an inhaler: step-by-step for every type
To use a metered-dose inhaler (the most common type of rescue inhaler), take off the cap, shake it, and breathe out away from the inhaler. Close your lips around the mouthpiece, press the canister once as you start a slow, deep breath in, and then hold your breath for about 10 seconds. Dry powder inhalers work differently. You don't shake them, and you breathe in fast and deep instead of slow. Continue reading
Is Salbutamol the same as Albuterol?
