If you are also using the inhalation form of a bronchodilator (medicine used to help relieve breathing problems), use the pentamidine inhalation at least 5 to 10 minutes after the bronchodilator, unless otherwise directed by your doctor. This will help to reduce the possibility of side effects. Do not use the bronchodilator or any medicine other than pentamidine in the nebulizer.
A bitter or metallic taste may occur during use of this medicine. Sucking on a hard candy after each treatment can help reduce this problem.
Cigarette smoking can increase the chance of coughing and difficulty in breathing during pentamidine inhalation therapy.
