Summary
Norepinephrine is a vasopressor used in shock, and lofexidine reduces sympathetic tone and blood pressure. Their effects are pharmacologically opposed, which may make the hemodynamic response to norepinephrine less predictable.
What this interaction means in plain words
Lofexidine and Norepinephrine have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Why it happens
Opposing adrenergic effects: central sympathetic inhibition versus direct vasoconstrictor action.
What to do
