Uses

This medication is used to treat a type of high blood pressure in the lungs (pulmonary arterial hypertension). Treprostinil helps to increase your ability to exercise and improves symptoms such as shortness of breath and tiredness. It works by relaxing and widening the blood vessels (arteries) in the lungs and other parts of the body so that blood can flow more easily. This medication belongs to a class of drugs known as vasodilators.

How to use

Read the Patient Information Leaflet provided by your pharmacist before you start using treprostinil and each time you get a refill. Follow the illustrated directions for the proper use of this medication. If you have any questions, ask your doctor or pharmacist.

This medication comes in a single-use cartridge. Do not swallow or open the cartridges. Inhale the contents of the cartridge by mouth using the inhaler device as directed by your doctor, usually 4 times daily during waking hours, at least 4 hours apart. This medication must always be used with its own special inhaler device. Always discard your old inhaler device after 7 days of use and use a new inhaler device.

Leave the cartridges sealed in the blister card until just before use. If stored in the refrigerator, bring the cartridge and inhaler device to room temperature for 10 minutes before using. Inhale the cartridge contents as directed to make sure you inhale all of the drug. Do not shake the inhaler after placing the cartridge into the inhaler device. Be sure to inhale deeply through the mouthpiece when using this drug. Hold your breath for as long as you comfortably can. Do not exhale or blow into the inhaler device. If two or more cartridges are prescribed, use only 1 cartridge at a time. Do not get this medication on the skin. If this happens, rinse the area with water.

The dosage is based on your medical condition and response to treatment.
