A thiazide diuretic that lowers blood pressure by reducing fluid volume through increased urine output and by relaxing blood vessels, widely used alone or in combination with other antihypertensives to treat high blood pressure, heart failure, and edema. It is also used to prevent kidney stones in patients with high urinary calcium. Potassium levels should be monitored as this medication can cause hypokalemia.

                                Hydrochlorothiazide + Lithium Carbonate
                            
                        

                        
                        
Thiazide diuretics increase lithium reabsorption in the proximal renal tubule, reliably causing lithium toxicity without dose adjustment.

                                Hydrochlorothiazide + Lisinopril
                            
                        

                        
                        
The ACE inhibitor and thiazide combination is guideline-recommended for hypertension but can cause first-dose hypotension and metabolic disturbances including hypokalemia or hyperkalemia.

                                Hydrochlorothiazide + Losartan
                            
                        

                        
                        
Losartan + hydrochlorothiazide is a guideline-recommended combination for hypertension; the primary interactions are additive hypotension and variable electrolyte effects.

                                Hydrochlorothiazide + Memantine
                            
                        

                        
                        
Hydrochlorothiazide may reduce renal clearance of memantine through alkalinisation of urine, as memantine elimination is pH-dependent; the clinical impact is generally minor.

                                Hydrochlorothiazide + Naproxen
                            
                        

                        
                        
Naproxen reduces the diuretic and antihypertensive efficacy of thiazide diuretics, blunting blood pressure control.

                                Hydrochlorothiazide + Gabapentin
                            
                        

                        
                        
Hydrochlorothiazide-induced sodium and fluid loss can increase the risk of dizziness and orthostatic hypotension when combined with gabapentin, which also causes dizziness and impairs balance.

                                Hydrochlorothiazide + Furosemide
                            
                        

                        
                        
Sequential nephron blockade with furosemide and thiazide diuretics produces a synergistic diuretic effect that can rapidly cause severe hypovolemia, hyponatremia, and hypokalemia.

                                Hydrochlorothiazide + Empagliflozin
                            
                        

                        
                        
The combination of empagliflozin and hydrochlorothiazide can cause additive volume depletion and hypotension, and may also increase the risk of genital mycotic infections through shared glucosuria.
