Summary
Propylhexedrine is a sympathomimetic nasal decongestant that is mainly used by inhalation. At normal doses systemic effects are small, but misuse or excessive dosing can raise blood pressure and heart rate. Any pressor effect would oppose hydralazine's action.

Hydralazine and Propylhexedrine have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
