How to Use This Medication

This medication is given by a health care professional as directed by your doctor, usually once every 4 weeks. It is given using a special machine called a nebulizer that changes the solution to a fine mist that you inhale. Each treatment usually takes 30 to 45 minutes. You may also be given another inhaled medication (such as albuterol) to help open your airways before each treatment with pentamidine. Learn and follow all instructions for the use of this medication and the nebulizer. If you have any questions, ask your doctor, pharmacist, or respiratory therapist.

The dosage is based on your medical condition and response to treatment.

Use this medication regularly to get the most benefit from it. To help you remember, mark your calendar to keep track of when to schedule the next dose.

Tell your doctor right away if you develop symptoms of infection such as breathing problems, cough, or fever between treatments.
