Consumer:Using cyclobenzaprine together with guanethidine may decrease the effects of guanethidine. Contact your doctor if your condition changes or if your blood pressure increases. If your doctor does prescribe these medications together, you may need a dose adjustment or need your blood pressure checked more often to safely use both medications. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
Professional:MONITOR: The manufacturer of cyclobenzaprine reports that it may block the antihypertensive effects of guanethidine. Loss of blood pressure control may result. The mechanism is unknown but may be related to inhibition of guanethidine uptake into adrenergic neurons.
MANAGEMENT: If patients receive this combination, their blood pressure should be closely monitored when initiating or discontinuing either drug. Either a different muscle relaxant or a different antihypertensive agent may be considered.
