Why this happens
Both amlodipine and doxazosin (Doxadura) work by relaxing and widening your blood vessels to lower blood pressure. When used together, their effects add up (an additive effect), which can sometimes lower blood pressure too much.
What you should do
It is common for doctors to prescribe these together, but you should be cautious. When starting this combination or increasing the dose, get up slowly from a bed or chair to avoid dizziness. Monitor your blood pressure regularly at home if possible. If you feel very dizzy, faint, or have a racing heartbeat, contact your doctor.
