Uses for iloprost

Iloprost (Inhalation) is used to treat the symptoms of pulmonary arterial hypertension (PAH). PAH is high blood pressure in the main artery that carries blood from the right side of the heart (the ventricle) to the lungs. When this high blood pressure occurs, the blood vessels in the lungs become tighter and have smaller openings. As a result, the right ventricle has to work harder to pump enough blood through the lungs. Iloprost is a synthetic (man-made) type of hormone called prostacyclin. Prostacyclin is normally made in the lungs and helps keep the blood vessels relaxed. People with PAH do not produce enough prostacyclin in their lungs. Iloprost will help the blood vessels relax, which increases blood flow to the lungs and decreases the workload on the heart.

This medicine is available only with your doctor's prescription.

Precautions while using iloprost

It is very important that your doctor checks your progress at regular visits to ensure that this medicine is working properly.

This medicine may cause your blood pressure to drop. Your doctor will check your blood pressure before you start the medicine and may check it during your regular office visits. You may also need to monitor your blood pressure at home. If you notice any changes to your recommended blood pressure, call your doctor right away.

Dizziness, lightheadedness, or fainting may occur after you use this medicine, especially when you get up suddenly from a lying or sitting position. Getting up slowly may help, but if the problem continues or gets worse, check with your doctor. Make sure you know how you react to this medicine before you drive, use machines, or do anything else that could be dangerous if you are dizzy or lightheaded.

Check with your doctor right away if you have chest pain, difficulty, fast, or noisy breathing, sometimes with wheezing, blue lips and fingernails, pale skin, increased sweating, coughing that sometimes produces a pink frothy sputum, shortness of breath, or swelling in the legs and ankles. These may be signs of pulmonary edema (fluid in the lungs).

Tell your doctor if you are pregnant or plan to become pregnant before using this medicine.

Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
