What is Iloprost?

Iloprost is a prescription medicine used to treat pulmonary arterial hypertension. To understand how it helps your body, it helps to look at how blood flows through your lungs. Think of the blood vessels carrying blood from your heart to your lungs as narrow tubes.

In pulmonary hypertension, these tiny blood vessels become squeezed, tight, and narrow. Because of this narrowing, your heart has to work much harder to pump blood through them. This extra strain makes your heart tired and raises blood pressure inside your lungs.

Iloprost steps in to help by relaxing those tight, narrowed blood vessels. Once the vessels open up, your heart does not have to work nearly as hard to pump blood. Lung pressure drops, breathing becomes easier, and you gain more energy for daily activities.

The most important rule is to use this medicine only under the direct guidance and prescription of your doctor. Using a medicine prescribed for someone else can cause serious harm.

Things to Tell Your Doctor First

Before your doctor prescribes Iloprost, they need a complete picture of your health. Make sure to tell your doctor right away if you have any of the following health conditions or personal circumstances:

  • Kidney problems: If you have any history of kidney disease or reduced kidney function.
  • Liver problems: If your liver does not work properly or you have a liver condition.
  • Low blood pressure: If your blood pressure tends to run lower than normal.
  • Allergies: If you are allergic to Iloprost, any other medicines, foods, dyes, or preservatives.
  • Pregnancy: If you are pregnant or plan to become pregnant soon.
  • Breastfeeding: If you are currently nursing or breastfeeding your baby.

Sharing these details keeps you safe. Your medical team relies on this information to decide if this treatment is the right match for your body.

How to Use This Medicine Correctly

Iloprost is a unique medicine that you do not swallow as a pill. Instead, it comes as a liquid that you breathe into your lungs through inhalation. You use a special machine called a nebulizer to turn the liquid into a fine mist.

Doctors typically require a specific device known as the I-neb AAD nebulizer for this treatment. The nebulizer transforms liquid medicine into an aerosol mist so you can breathe it deep into your lungs with a normal mouth breath.

Important Rules to Remember:

  • Use the correct device: Always use only the exact nebulizer model recommended by your doctor.
  • Do not mix medicines: Never mix any other medicine into the nebulizer chamber with your Iloprost dose.
  • Follow your schedule: Take the medicine exactly as many times a day as your doctor instructs. Never take extra doses on your own.
  • Read the instructions: Read the patient information leaflet that comes with your medicine carefully. Ask your doctor if anything is unclear.

Giving This Medicine to Children?

If a child needs this medicine, special precautions and careful supervision are required. Talk thoroughly with your pediatrician to understand the exact steps for pediatric use.

What to Do If You Take Too Much

If you believe you used more medicine than prescribed, act quickly. Call your local emergency services right away or go straight to the nearest hospital emergency department (ER).

What to Do If a Dose is Missed?

If you forget to take a dose of Iloprost, take it as soon as you remember. However, if it is almost time for your next scheduled dose, skip the missed dose entirely.

Simply return to your normal dosing schedule with the next dose. Never take two doses at the same time to make up for a missed dose.

Other Medicines That May Interact

Other products and medicines can interact with Iloprost and change how it works in your body. Share a complete list of everything you take, including vitamins, herbal supplements, and over-the-counter drugs, with your doctor.

  • Blood thinners: Medicines that prevent blood clots, such as warfarin, aspirin, clopidogrel, apixaban, or rivaroxaban.
  • Blood pressure medicines: Other drugs used to lower high blood pressure.
  • Heart medicines: Treatments prescribed for various heart conditions.
  • Vessel-expanding drugs: Other similar medicines like cilostazol, dipyridamole, or pentoxifylline.

If you smoke cigarettes, drink alcohol, or use recreational substances, tell your doctor as well. These substances can alter how your body processes your treatment.

Things to Watch While Using This Medicine

  • Medical checkups: Attend all scheduled clinic appointments so your doctor can check your progress. Tell your doctor if your symptoms stay the same or get worse.
  • Dizziness and sleepiness: This medicine can make you feel dizzy, lightheaded, or sleepy. Avoid driving or operating machinery until you know how the medicine affects you.
  • Changing body positions: Do not jump up quickly from a sitting or lying position. Stand up slowly to avoid fainting, especially for older adults.
  • Alcohol: Avoid drinking alcohol while using this medicine, as it can worsen side effects like low blood pressure.
