Breelib device
Breelib is a medical device called a nebuliser. A Nebuliser turns liquid drug into a fine mist which a patient can breathe into their lungs to help with their symptoms. Breelib should only ever be used to take the drug Ventavis (iloprost trometamol).
This website contains information for UK Breelib patients, their caregivers and healthcare professionals to help with using and caring for the device as well as other helpful pulmonary hypertension-related topics and resources.
