Is hydralazine a water pill (diuretic)?

Hydralazine is not a water pill (diuretic). It is a vasodilator that works by relaxing blood vessels to lower blood pressure. Unlike diuretics (water pills), hydralazine will not make you pee more. Hydralazine should not be confused with hydrochlorothiazide, which is a diuretic (water pill).



How fast does hydralazine pill work?

Hydralazine usually works within an hour, but its effects only last for 3-7 hours. That’s why you need to take this medicine 2-4 times a day to control blood pressure.



Is it safe to take hydralazine during pregnancy?

There is not enough data to say whether hydralazine tablets are safe during pregnancy.  Tell your healthcare provider if you become pregnant while on this medicine.

Does alcohol affect hydralazine?

Alcohol can affect hydralazine and cause side effects such as headache, dizziness, flushing, and low blood pressure.
