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