How do you counsel and manage cough as a side effect when initiating inhaled treprostinil in a patient with IPF?

At the present time, since it is prescribed in ILD-PH, I try to ensure that they are euvolemic and have precapillary pulmonary arterial hypertension (PAH). Most patients say it makes the throat dry; they do drink water before and after. I will have them do an albuterol inhaler or an albuterol and steroid combination inhaler before treprostinil. Asking them to try lozenges is sometimes helpful.
