Pentamidine Oral Inhalation

Keep all appointments with your doctor and the laboratory. Your doctor will order certain lab tests to check your response to pentamidine.

You may develop a cough while using aerosol pentamidine. The cough may be more severe if you smoke or have a history of asthma. If you experience cough or difficulty breathing, call your doctor. Your doctor may suggest slowing the aerosol stream or may prescribe a bronchodilator (medication that opens the airways) to use before your pentamidine inhalation.

Do not let anyone else take your medication. Ask your pharmacist any questions you have about refilling your prescription.

It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
