How should I use Xopenex HFA?

Follow all directions on your prescription label. Do not use this medicine in larger or smaller amounts or for longer than recommended.

Read all patient information, medication guides, and instruction sheets provided to you. Ask your doctor or pharmacist if you have any questions.

Any child using Xopenex HFA should be supervised by an adult while using this medicine.

Prime the inhaler device before your first use. Pump 4 test sprays into the air, away from your face. Shake the inhaler for at least 5 seconds before each spray. Prime again whenever the inhaler has not been used in longer than 3 days.

To use the inhaler:

Store the levalbuterol inhaler with the mouthpiece down. Keep the inhaler at room temperature away from heat, sunlight, or freezing temperatures. If your inhaler has a dose number indicator on it, throw away the inhaler when the number displays "0" to show that all sprays have been used.

Keep the inhaler canister away from open flame or high heat, such as in a car on a hot day. The canister may explode if it gets too hot. Do not puncture or burn an empty inhaler canister.

Levalbuterol concentrate solution is given with a nebulizer. The concentrate must be mixed with a liquid (diluent) before using it. Ask your pharmacist about which diluent to use and where you can buy it. Be sure you understand how to properly mix the medicine and place it into the nebulizer.

To use the solution with a nebulizer:

Do not use the nebulizer solution if it does not appear clear and colorless.

Store the levalbuterol concentrate vials in the protective foil pouch at room temperature, away from moisture, heat, and light. Keep each vial in the foil pouch until you are ready to prepare a dose in the nebulizer.

Each single-use plastic vial of levalbuterol concentrate is for one use only. Throw away after one use, even if there is still some medicine left in it after inhaling your dose.

Asthma is often treated with a combination of drugs. Use all medications as directed by your doctor. Do not change your doses or medication schedule without your doctor's advice.

Using too much levalbuterol or using it too often can cause life-threatening side effects. Seek medical attention if you think your asthma medications are not working as well. An increased need for medication could be an early sign of a serious asthma attack.

What happens if I miss a dose?

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.

Use Xopenex HFA regularly to get the most benefit. Get your prescription refilled before you run out of medicine completely.

What happens if I overdose?

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. An overdose of levalbuterol can be fatal.

What should I avoid while using Xopenex HFA?
