Patient information

(albuterol sulfate) Inhalation Aerosol


Patient's Instructions for Use

Figure 1

Figure 2

Before using your PROVENTIL® HFA (albuterol sulfate) Inhalation Aerosol, read complete instructions carefully. Children should use PROVENTIL HFA Inhalation Aerosol under adult supervision, as instructed by the patient's doctor

Please note thatindicates that this inhalation aerosol does not contain chlorofluorocarbons (CFCs) as the propellant.

  1. SHAKE THE INHALER WELL immediately before each use. Then remove the cap from the mouthpiece (see Figure 1). Check mouthpiece for foreign objects prior to use. Make sure the canister is fully inserted into the actuator.
  2. As with all aerosol medications, it is recommended to prime the inhaler before using for the first time and in cases where the inhaler has not been used for more than 2 weeks. Prime by releasing four “test sprays” into the air, away from your face.
  3. BREATHE OUT FULLY THROUGH THE MOUTH, expelling as much air from your lungs as possible. Place the mouthpiece fully into the mouth, holding the inhaler in its upright position (see Figure 2) and closing the lips around it.
  5. HOLD YOUR BREATH AS LONG AS POSSIBLE, up to 10 seconds. Before breathing out, remove the inhaler from your mouth and release your finger from the canister.
  6. If your physician has prescribed additional puffs, wait 1 minute, shake the inhaler again, and repeat steps 3 through 5. Replace the cap after use.

Routine cleaning instructions:

Step 1. To clean, remove the canister and mouthpiece cap. Wash the mouthpiece through the top and bottom with warm running water for 30 seconds at least once a week (see Figure A). Never immerse the metal canister in water.

Figure A

Wash mouthpiece under warm running water.

Figure B

Allow mouthpiece to air dry, such as overnight.

Figure C

When blocked, little or no medicine comes out.

Step 2. To dry, shake off excess water and let the mouthpiece air dry thoroughly, such as overnight (see Figure B). When the mouthpiece is dry, replace the canister and the mouthpiece cap. Blockage from medication buildup is more likely to occur if the mouthpiece is not allowed to air dry thoroughly.

IF YOUR INHALER HAS BECOME BLOCKED (little or no medication coming out of the mouthpiece, see Figure C), wash the mouthpiece as described in Step 1 and air dry thoroughly as described in Step 2.

IF YOU NEED TO USE YOUR INHALER BEFORE IT IS COMPLETELY DRY, SHAKE OFF EXCESS WATER, replace the canister, and test spray twice into the air, away from your face, to remove most of the water remaining in the mouthpiece. Then take your dose as prescribed. After such use, rewash and air dry thoroughly as described in Steps 1 and 2.

8. The correct amount of medication in each inhalation cannot be assured after 200 actuations, even though the canister is not completely empty. The canister should be discarded when the labeled number of actuations have been used. Before you reach the specific number of actuations, you should consult your physician to determine whether a refill is needed. Just as you should not take extra doses without consulting your physician, you also should not stop using PROVENTIL HFA Inhalation Aerosol without consulting your physician.

You may notice a slightly different taste or spray force than you are used to with PROVENTIL HFA Inhalation Aerosol, compared to other albuterol inhalation aerosol products.


Use only as directed by your physician.


The action of PROVENTIL® HFA Inhalation Aerosol should last up to 4 to 6 hours. PROVENTIL HFA Inhalation Aerosol should not be used more frequently than recommended. Do not increase the number of puffs or frequency of doses of PROVENTIL HFA Inhalation Aerosol without consulting your physician. If you find that treatment with PROVENTIL HFA Inhalation Aerosol becomes less effective for symptomatic relief, your symptoms become worse, and/or you need to use the product more frequently than usual, medical attention should be sought immediately. While you are taking PROVENTIL HFA Inhalation Aerosol, other inhaled drugs should be taken only as directed by your physician. If you are pregnant or nursing, contact your physician about the use of PROVENTIL HFA Inhalation Aerosol.

Common adverse effects of treatment with PROVENTIL HFA Inhalation Aerosol include palpitations, chest pain, rapid heart rate, tremor, or nervousness. Effective and safe use of PROVENTIL HFA Inhalation Aerosol includes an understanding of the way that it should be administered. Use PROVENTIL HFA Inhalation Aerosol only with the yellow actuator supplied with the product. The PROVENTIL HFA Inhalation Aerosol actuator should not be used with other aerosol medications.

For best results, use at room temperature. Avoid exposing product to extreme heat and cold.

Shake well before use.

Cautions for Albuterol Sulfate


  • Known hypersensitivity to albuterol or any ingredients in the formulations.j

  • Known history of hypersensitivity to soya lecithin or related food products such as soybeans or peanuts; atropine and its derivatives; or any other ingredient in the specific formulation (albuterol sulfate in fixed combination with ipratropium bromide).233 243



Acute or Worsening Asthma

Oral inhalation therapy is intended for the acute symptomatic relief of bronchospasm.188 189 190 191 192 249 If control of mild asthma deteriorates such that regular (i.e., exceeding 4 times daily) use of a short-acting β2-agonist becomes necessary, institute maintenance therapy (e.g., inhaled corticosteroids)188 189 191 249 and discontinue regular use of short-acting β2-agonists in such patients; instead, use short-acting β2-agonists only as a supplement for relief of acute asthma symptoms.188 189 190 191 192 194 197 249 Contact a clinician for reevaluation if control of mild asthma deteriorates.114 154 192 193 196

Failure to respond to a previously effective dosage of albuterol may indicate seriously worsening asthma.156 157 181 188 189 190 191 192 193 194 196 197 237 241 242 243 244 249 Reevaluate asthma therapy and institute alternative regimens or therapy.156 157 181 188 189 190 191 192 193 194 196 197 237 241 242 243 244 249 Discontinue and contact a clinician if decreased effectiveness occurs; do not increase the dose or frequency of administration.241

Excessive Doses

Possible fatalities associated with excessive use of inhaled sympathomimetic drugs.114 139 153 237 241 243 255 258 145 154 212 262 208 146 181 233 The safety of concomitant use of >8 inhalations per day of a short-acting β2-adrenergic agonist with a long-acting β2-agonist (e.g., salmeterol) oral inhalation therapy has not been established.192 287 (See Sympathomimetic Agents under Interactions.)

Paradoxical Bronchospasm

What is albuterol inhalation (accuneb, proair hfa, proventil, proventil hfa, relion ventolin hfa, ventolin hfa)?

Albuterol is a bronchodilator that relaxes muscles in the airways and increases air flow to the lungs.

Albuterol inhalation is used to treat or prevent bronchospasm in people with reversible obstructive airway disease. Albuterol is also used to prevent exercise-induced bronchospasm.

Albuterol inhalation may also be used for purposes not listed in this medication guide.

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.
