Consumer information for this interaction is not currently available.
MONITOR: Theoretically, the pharmacologic effects of agents that act through agonism at the alpha receptor may be antagonized by those that act via antagonism at the same receptor, and vice versa. Alpha-1 agonists and alpha agonists with beta-agonist effects exert opposing effects on vascular tone and blood pressure than alpha-1 antagonists. Some of these agents act on both alpha-1 and alpha-2 receptors, though they may have a stronger affinity for one or the other. The severity of the interaction may also be influenced by the degree of systemic absorption of each agent.
MANAGEMENT: Monitoring for diminished effects on blood pressure and vasoconstriction is recommended if an alpha-agonist (e.g., epinephrine, norepinephrine, ephedrine, metaraminol) is coadministered with an alpha-antagonist (e.g., phentolamine, phenoxybenzamine, terazosin). If the concomitant alpha agonist being used also acts on beta receptors, the effects of unopposed beta stimulation should also be considered.
Drug and food interactions
prazosin food
Applies to: prazosin
Ask your doctor before using prazosin together with ethanol. Using prazosin with ethanol can lower your blood pressure. This can cause dizziness or feeling like you might pass out, especially when getting up from a sitting or lying position. This may be more likely to occur when you first start taking either of these medications. You may need a dose adjustment or need your blood pressure checked more often if you take both medications. You may develop flushing, warmth or redness under your skin or tingly feeling after alcohol intake (especially in you are of Asian descent) and should be advised to avoid alcohol or limit your intake. 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.
ePHEDrine food
Applies to: ephedrine
Both ePHEDrine and caffeine can increase blood pressure and heart rate, and combining them may enhance these effects. Talk to your doctor before using these medications, especially if you have a history of high blood pressure or heart disease. You may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications. Contact your doctor if your condition changes or you experience increased side effects. 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.
