Prazosin/Polythiazide

Prazosin and polythiazide are often prescribed together to help keep high blood pressure under control. Prazosin helps relax blood vessels to make it easier for blood to flow through them, while polythiazide is a diuretic that stimulates the kidneys to remove excess fluids from the bloodstream. These medications are prescribed for people who have not responded well to other blood pressure medications.

Side Effects/Warnings

This medication is not meant for people who have never been on high blood pressure medication before. It is a very powerful combination that has to be adjusted carefully to ensure that patients don’t have a severe drop in blood pressure. It should only be used if other blood medications fail, and patients should be monitored carefully and have their dose adjusted frequently until the medication works correctly.
