Before taking enalapril and hydrochlorothiazide,
tell your doctor and pharmacist if you are allergic to enalapril (Vasotec, in Vaseretic); hydrochlorothiazide (HCTZ, Microzide, Oretic); angiotensin-converting enzyme (ACE) inhibitors such as benazepril (Lotensin, in Lotrel), captopril (Capoten), fosinopril (Monopril), lisinopril (in Prinzide, in Zestoretic), moexipril (Univasc, in Uniretic), perindopril (Aceon), quinapril (Accupril, in Accuretic, in Quinaretic), ramipril (Altace), and trandolapril (Mavik, in Tarka); sulfa drugs; any other medications; or any of the ingredients in enalapril and hydrochlorothiazide tablets. Ask your pharmacist for a list of the ingredients.
tell your doctor or pharmacist if you are taking valsartan and sacubitril (Entresto) or if you have stopped taking it within the last 36 hours. Your doctor will probably tell you not to take enalapril and hydrochlorothiazide, if you are also taking valsartan and sacubitril. Also, tell your doctor if you have diabetes and you are taking aliskiren (Tekturna, in Amturnide, Tekamlo, Tekturna HCT). Your doctor will probably tell you not to take enalapril and hydrochlorothiazide if you have diabetes and you are also taking aliskiren.
tell your doctor and pharmacist what prescription and nonprescription medications, vitamins, nutritional supplements, and herbal products you are taking. Be sure to mention any of the following: aspirin and other nonsteroidal anti-inflammatory medications (NSAIDs) such as indomethacin (Indocin, Tivorbex); cholestyramine (Prevalite); colestipol (Colestid); diuretics ('water pills'); insulin or oral medications for diabetes; lithium (Lithobid); oral steroids such as dexamethasone, methylprednisolone (Medrol), and prednisone (Rayos); other medications for high blood pressure; pain medications; phenobarbital (Luminal); and potassium supplements. Your doctor may need to change the doses of your medications or monitor you carefully for side effects.
tell your doctor if you have or have ever had heart, parathyroid, liver, or kidney disease; lupus; diabetes; allergies; asthma; gout; or angioedema (a condition that causes hives, difficulty breathing, and painful swelling of the face, lips, throat, tongue, hands, or feet).
tell your doctor if you are breast-feeding.
if you are having surgery, including dental surgery, tell the doctor or dentist that you are taking enalapril and hydrochlorothiazide.
ask your doctor about the safe use of alcoholic beverages while you are taking enalapril and hydrochlorothiazide. Alcohol can make the side effects from enalapril and hydrochlorothiazide worse.
you should know that diarrhea, vomiting, not drinking enough fluids, and sweating a lot can cause a drop in blood pressure, which may cause lightheadedness and fainting.
