What is the most important information I should know about Proventil?

• Seek medical attention if you notice that you require more than your usual or more than the maximum amount of any asthma medication in a 24-hour period. An increased need for medication could be an early sign of a serious asthma attack.

What is Proventil?

• Proventil works by relaxing muscles in the airways to improve breathing.
• Proventil is used to treat bronchospasm (wheezing, shortness of breath) associated with reversible obstructive airway disease such as asthma.
• Proventil may also be used for conditions other than those listed in this medication guide.

What should I discuss with my healthcare provider before taking Proventil?

• Before taking Proventil, tell your doctor if you have
  • heart disease or high blood pressure;
  • epilepsy or another seizure disorder;
  • diabetes;
  • an overactive thyroid (hyperthyroidism);
  • difficulty swallowing;
  • liver disease; or
  • kidney disease.
• You may not be able to take Proventil or you may require a dosage adjustment or special monitoring during treatment if you have any of the conditions listed above.
• Proventil is in the FDA pregnancy category C. This means that it is not known whether it will harm an unborn baby. Do not take Proventil without first talking to your doctor if you are pregnant or could become pregnant during treatment.
• It is not known whether Proventil passes into breast milk. Do not take Proventil without first talking to your doctor if you are breast-feeding a baby.

How should I take Proventil?

• Take Proventil exactly as directed by your doctor. If you do not understand these directions, ask your pharmacist, nurse, or doctor to explain them to you.
• Take each dose with a full glass of water.
• To ensure that you get a correct dose, measure the liquid forms of Proventil with a special dose-measuring spoon or cup, not with a regular table spoon. If you do not have a dose-measuring device, ask your pharmacist where you can get one.
• Do not break, crush, or chew the Volmax or Proventil Repetabs tablets. These are specially formulated to release the medication slowly in the body. The Volmax tablets have an outer shell that is not absorbed by the body. Occasionally, this shell may be seen in the stool. This is not a problem as the medication has been absorbed by the body.
• Seek medical attention if you notice that you require more than your usual or more than the maximum amount of any asthma medication in a 24-hour period. An increased need for medication could be an early sign of a serious asthma attack.
• Store the Volmax brand of Proventil tablets in the refrigerator between 36 and 46 degrees Fahrenheit (2 and 8 degrees Celsius).
• Store all other forms of Proventil at room temperature away from moisture and heat.

What happens if I miss a dose?
