Drug Information:
Hydrochlorothiazide is a thiazide diuretic (water pill) that helps prevent your body from absorbing too much salt, which can cause fluid retention. Metoprolol is a beta-blocker. Beta-blockers affect the heart and circulation (blood flow through arteries and veins). Dutoprol is a combination medicine used to treat high blood pressure (hypertension). Dutoprol may also be used for purposes not listed in this medication guide. You should not use Dutoprol if you have a serious heart condition such as "sick sinus syndrome" or "AV block" (unless you have a pacemaker), slow heartbeats that have caused you to faint, or if your heart cannot pump blood properly.
