Which drugs or supplements interact with acebutolol?

  • The use of beta blockers together with fenoldopam
    (Corlopam), a drug used to manage severe
    high blood pressure, may result in
    low blood pressure since beta-adrenergic blocking drugs add to the
    blood pressure-lowering effects of fenoldopam.
  • With concomitant use of
    clonidine (Catapres) and beta-adrenergic blocking
    drugs, severe
    high blood pressure may occur if patients abruptly discontinue the
    clonidine. Because of this effect, it is advisable to discontinue
    beta-adrenergic blocking drugs prior to starting clonidine.
  • Using epinephrine (Adrenalin,
    EpiPen) and beta-adrenergic blocking drugs
    together causes high blood pressure and a slow heartbeat since the
    beta-adrenergic stimulating effects of epinephrine that raise blood pressure and
    heart rate are exaggerated by the beta-adrenergic blocking drugs which prevent
    dilation of the blood vessels and increase the heart rate. To avoid this effect,
    it is best not to use both drugs together. If, however, both drugs are
    administered together, it is important to monitor blood pressure levels. Also,
    high blood pressure and a slow heartbeat are less likely to occur if
    beta-adrenergic blocking drugs that are selective for the heart such as atenolol
    (Tenormin) and Sectral (Sectral) are used.
  • Epinephrine- and norepinephrine-depleting drugs, such as
    (Harmonyl), may have an additive effect when given with beta-blocking drugs and
    cause an abnormally slow heart beat or
    low blood pressure, which may give rise
    to dizziness or
