How should I use treprostinil inhalation?
Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose. Use the medicine exactly as directed.
Do not swallow treprostinil inhalation. The medicine should be inhaled using only the Tyvaso inhalation system.
Treprostinil inhalation should be used only with a Tyvaso inhalation system. Read and carefully follow any Instructions for Use provided with your medicine. Ask your doctor or pharmacist if you do not understand these instructions.
Treprostinil inhalation is usually given 4 times per day at evenly spaced intervals during waking hours. Use exactly as directed on the label, or as prescribed by your doctor.
Do not mix other inhalation medicines with treprostinil in the Tyvaso inhalation system.
Wash your hands before preparing your treprostinil doses in the inhalation system.
Before your first dose of each day, twist off the top of one ampule and empty the contents into the medicine cup of the inhalation system. One ampule of treprostinil inhalation contains enough medicine for all 4 of a day's doses.
At the end of the day after your last dose, empty and rinse out the medicine cup, even if there is still some medicine left in it.
The effects of treprostinil inhalation will lessen over time between doses. Talk with your doctor if you need to time your dosing around any planned activities.
Do not use more than 12 breaths per treatment session, 4 times per day.
Use treprostinil regularly to get the most benefit. You should not reduce your dose or stop using treprostinil suddenly. Stopping suddenly may make your condition worse. Get your prescription refilled before you run out of medicine completely. Make sure you have a backup inhalation system available so as not to interrupt your treatment if one system stops working.
Call your doctor if your symptoms do not improve, or if they get worse while using treprostinil inhalation.
Store treprostinil ampules in their foil pouch at room temperature away from moisture, heat, and light. Once you have opened a foil pouch, the ampules in it should be used within 7 days.
Store the inhalation system upright and tightly capped with the plugs when not in use. Any treprostinil in the medicine cup must be used within 24 hours. Throw away any unused medicine at the end of the day after your last dose.
