What is Accuretic?
Hydrochlorothiazide is a thiazide diuretic (water pill) that helps prevent your body from absorbing too much salt, which can cause fluid retention.
Quinapril is an ACE inhibitor. ACE stands for angiotensin converting enzyme. Quinapril lowers blood pressure and also relieves symptoms of fluid retention.
Accuretic is a combination medicine used to treat hypertension (high blood pressure).
Accuretic may also be used for purposes not listed in this medication guide.
Do not use if you are pregnant. If you become pregnant, stop taking this medicine and tell your doctor right away.
You should not use Accuretic if you have ever had angioedema, or if you are unable to urinate. Do not take this medicine within 36 hours before or after taking medicine that contains sacubatril (such as Entresto).
Before taking this medicine
You should not use this medicine if you are allergic to hydrochlorothiazide or quinapril, or if:
you have a history of angioedema;

Do not take Accuretic within 36 hours before or after taking medicine that contains sacubatril (such as Entresto).
If you have diabetes, do not use Accuretic together with any medication that contains aliskiren (such as Tekturna or Tekamlo).

How should I take Accuretic?
Follow all directions on your prescription label. Your doctor may occasionally change your dose. Do not take this medicine in larger or smaller amounts or for longer than recommended.
Call your doctor if you have ongoing vomiting or diarrhea, or if you are sweating more than usual. You can easily become dehydrated while taking quinapril. This can lead to very low blood pressure, electrolyte disorders, or kidney failure.
Your blood pressure will need to be checked often. Your blood and urine may also be tested if you have been vomiting or are dehydrated. Visit your doctor regularly.
Keep using this medicine as directed, even if you feel well. High blood pressure often has no symptoms. You may need to use blood pressure medication for the rest of your life.
If you need surgery, tell the surgeon ahead of time that you are using Accuretic. You may need to stop using the medicine for a short time.
Store at room temperature away from moisture, heat, and light.
What happens if I miss a dose?
Take the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not take extra medicine to make up the missed dose.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.
What should I avoid while taking Accuretic?
Do not use salt substitutes or potassium supplements while taking quinapril, unless your doctor has told you to.
Avoid getting up too fast from a sitting or lying position, or you may feel dizzy. Get up slowly and steady yourself to prevent a fall.
Avoid becoming overheated or dehydrated during exercise, in hot weather, or by not drinking enough fluids. Follow your doctor's instructions about the type and amount of liquids you should drink. In some cases, drinking too much liquid can be as unsafe as not drinking enough.
Drinking alcohol can further lower your blood pressure and may increase certain side effects of this medicine.
