What is Flolan?

Flolan is a prostaglandin (a hormone-like substance that occurs naturally in the body). Prostaglandins help to control functions in the body such as blood pressure and muscle contractions.

Flolan is used to treat pulmonary arterial hypertension (PAH). It improves your ability to exercise.

Flolan may also be used for purposes not listed in this medication guide.

Important Information

You should not use this medication if you are allergic to Flolan, if you have breathing problems when you first start using this medicine, or if you have congestive heart failure caused by a decrease in your heart's ability to pump blood back into the body.

Before using Flolan, tell your doctor if you have a bleeding or blood clotting disorder, heart disease, liver or kidney disease, or high blood pressure.

Flolan is injected into a vein using an infusion pump, usually through a permanent central intravenous (IV) catheter placed into a large vein (such as in your chest). You may need to use this medication for many years.

You may be shown how to use an infusion pump at home. Do not self-inject this medicine if you do not fully understand how to give the injection and properly dispose of used needles, IV tubing, and other items used to inject the medicine.

You will receive your first dose of this medicine in a hospital or clinic setting to quickly treat any serious side effects that occur. Your blood pressure and heart rate may also need to be monitored whenever your dose is changed.

Tell your doctor about all other drugs you use, especially medicines to prevent blood clots.

Do not stop using Flolan without first talking to your doctor, even if you feel fine or have no symptoms. Even short breaks in the flow of your medication through the IV can cause the treatment to stop working. Missing doses or stopping suddenly may make your condition worse and you may have symptoms such as dizziness, weakness, or trouble breathing.

Call your doctor if your symptoms do not improve, or if they get worse while using Flolan.
