MedicineNet and I understand that I may opt out of MedicineNet subscriptions at any time. DiureticsDiuretics are among the oldest known medications for treating high blood pressure. They work in the tiny tubes (tubules) of the kidneys to promote the removal of salt from the body. Water (fluid) also is removed along with the salt; however, the exact mechanism whereby diuretics lower blood pressure is not clearly known. The leading theory is that they directly cause the muscles surrounding blood vessels to relax. Diuretics may be used alone for high blood pressure. More frequently, however, low doses of diuretics are used in combination with other medications for high blood pressure to enhance the effect of the other medications. Common side effects of diruetics Dehydration Low blood potassium Low blood pressure Fatigue Increased blood glucose Increased level of uric acidThis list is not does not include all side effects or adverse events for diuretics. This class of medicine also are used for other health conditions, for example: Congestive heart failure Peripheral edema Pulmonary edema High potassium blood levelsMost commonly used diuretics to treat hypertensionhydrochlorothiazide (Hydrodiuril)chlorthalidone The loop diuretics furosemide (Lasix), bumetanide (Bumex), and torsemide (Demadex)The combination of triamterene and hydrochlorothiazide (Dyazide)metolazone (Zaroxolyn)The thiazide drugs are related to sulfa drugs. For those individuals who are allergic to sulfa drugs, ethacrynic acid, a loop diuretic, is a good option. Diuretics probably should not be used in pregnant women. From Alpha-blockersMuscles surrounding blood vessels have alpha receptors. Stimulation of alpha receptors, like stimulation of beta receptors, cause the muscles surrounding the arteries to contract and narrow the arteries. By blocking the alpha receptor, alpha-blockers relax the muscles and lower blood pressure.Common side effects of alpha blockers Low blood pressure Dizziness Nausea WeaknessExamples of generic and brand names available for alpha blockersterazosin (Hytrin - brand name discontinued in the US)doxazosin (Cardura)This list is not does not include all side effects or adverse events for alpha blockers. Alpha blockers also are used for treating a health problem called benign prostate hyperplasia (BPH).Alpha-beta blockersAlpha-beta blockers work the same way as alpha-blockers but also slow the heartbeat as
