Quinaretic is used for:
Treating high blood pressure. It may also be used for other conditions as determined by your doctor.
Quinaretic is an angiotensin-converting enzyme (ACE) inhibitor and thiazide diuretic combination. It works by causing blood vessels to relax (widen) and increasing the excretion of excess fluid, which lowers blood pressure.
Do NOT use Quinaretic if:
- you are allergic to any ingredient in Quinaretic or any other sulfonamide medicine (eg, glyburide, probenecid, sulfamethoxazole)
- you have a history of angioedema (swelling of the hands, face, lips, eyes, throat, or tongue; difficulty swallowing or breathing; or hoarseness) caused by treatment with an ACE inhibitor
- you are pregnant
- you have severe kidney problems or are unable to urinate
- you are taking a medicine that contains aliskiren and you also have diabetes or kidney problems. Check with your doctor or pharmacist if you are not sure if a medicine you take contains aliskiren
- you are taking dextran sulfate, dofetilide, or ketanserin
Contact your doctor or health care provider right away if any of these apply to you.

Some MEDICINES MAY INTERACT with Quinaretic. Tell your health care provider if you are taking any other medicines, especially any of the following:
- Eplerenone, potassium-sparing diuretics (eg, amiloride, spironolactone), potassium supplements, or salt substitutes containing potassium because the risk of high blood potassium levels may be increased
- Everolimus, sirolimus, or temsirolimus because the risk of angioedema may be increased
- Aliskiren or angiotensin receptor blockers (eg, losartan) because the risk of certain side effects (eg, kidney problems, high blood potassium levels, low blood pressure) may be increased
- Nonsteroidal anti-inflammatory drugs (NSAIDs) (eg, celecoxib, ibuprofen, indomethacin) because they may decrease Quinaretic's effectiveness and the risk of serious kidney problems may be increased

- Dextran sulfate, digoxin, dofetilide, ketanserin, lithium, or thiopurines (eg, azathioprine) because the risk of their side effects may be increased by Quinaretic
- Insulin, oral hypoglycemics (eg, glyburide), or tetracycline because their effectiveness may be decreased by Quinaretic
This may not be a complete list of all interactions that may occur. Ask your health care provider if Quinaretic may interact with other medicines that you take. Check with your health care provider before you start, stop, or change the dose of any medicine.
How to use Quinaretic:
Use Quinaretic as directed by your doctor. Check the label on the medicine for exact dosing instructions.
- Take Quinaretic by mouth with or without food.
- Quinaretic may increase the amount of urine or cause you to urinate more often when you first start taking it. To keep this from disturbing your sleep, try to take your dose before 6 pm.
- If you are taking a tetracycline antibiotic, a quinolone antibiotic (eg, ciprofloxacin, levofloxacin), or colestipol or cholestyramine for high cholesterol, ask your doctor or pharmacist how to take it with Quinaretic. This product contains magnesium, which can interfere with absorption of these medicines.
- Take Quinaretic on a regular schedule to get the most benefit from it.
- Taking Quinaretic at the same time each day will help you remember to take it.
- Continue to take Quinaretic even if you feel well. Do not miss any doses.
- If you miss a dose of Quinaretic, take it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once.
Ask your health care provider any questions you may have about how to use Quinaretic.
Important safety information:
- Quinaretic may cause drowsiness, dizziness, light-headedness, or fainting. These effects may be worse if you take it with alcohol or certain medicines. Use Quinaretic with caution. Do not drive or perform other possibly unsafe tasks until you know how you react to it.
- Quinaretic may cause dizziness, light-headedness, or fainting; alcohol, hot weather, exercise, or fever may increase these effects. To prevent them, sit up or stand slowly, especially in the morning. Sit or lie down at the first sign of any of these effects.
- Report any light-headedness or fainting to your doctor immediately. Your risk of light-headedness or fainting may be increased if you experience diarrhea, vomiting, or excessive sweating, if you do not drink enough fluids, or if you are on a low-salt (sodium) diet.
- Patients who take medicine for high blood pressure often feel tired or run down for a few weeks after starting treatment. Be sure to take your medicine even if you may not feel "normal." Tell your doctor if you develop any new symptoms.
- Quinaretic has magnesium in it. Before you start any new medicine, check the label to see if it has magnesium in it too. If it does or if you are not sure, check with your doctor or pharmacist.
- Quinaretic may cause you to become sunburned more easily. Avoid the sun, sunlamps, or tanning booths until you know how you react to Quinaretic. Use a sunscreen or wear protective clothing if you must be outside for more than a short time.
- Quinaretic may cause a serious side effect called angioedema. Black patients may be at greater risk of developing this side effect. Contact your doctor at once if you develop swelling of the hands, face, lips, eyes, throat, or tongue; difficulty swallowing or breathing; or hoarseness.
- Quinaretic contains hydrochlorothiazide, a sulfonamide, which can cause certain eye problems (myopia, angle-closure glaucoma). Your risk may be increased if you are allergic to sulfonamide medicines (eg, sulfamethoxazole) or to penicillin antibiotics (eg, amoxicillin). Untreated angle-closure glaucoma can lead to permanent vision loss. If these eye problems occur, symptoms usually occur within hours to weeks of starting Quinaretic. Contact your doctor immediately if you experience symptoms such as vision changes (eg, decreased vision clearness) or eye pain.
- Dehydration, excessive sweating, vomiting, or diarrhea may lead to a fall in blood pressure. Contact your health care provider at once if any of these symptoms occur.
- Check with your doctor before you use a salt substitute or a product that has potassium in it.
- Quinaretic may lower the ability of your body to fight infection. Avoid contact with people who have colds or infections. Tell your doctor if you notice signs of infection like fever, sore throat, rash, or chills.
- It may take 1 to 2 weeks for Quinaretic to work. Do not stop taking Quinaretic without checking with your doctor.
- Tell your doctor or dentist that you take Quinaretic before you receive any medical or dental care, emergency care, or surgery.
- Diabetes patients - Quinaretic may affect your blood sugar. Check blood sugar levels closely. Ask your doctor before you change the dose of your diabetes medicine.
- Quinaretic may raise your blood sugar. High blood sugar may make you feel confused, drowsy, or thirsty. It can also make you flush, breathe faster, or have a fruit-like breath odor. If these symptoms occur, tell your doctor right away.
- Quinaretic may interfere with certain lab tests, including parathyroid function tests. Be sure your doctor and lab personnel know you are taking Quinaretic.
- Lab tests, including liver and kidney function, blood pressure, complete blood cell counts, and blood electrolytes, may be performed while you take Quinaretic. These tests may be used to monitor your condition or check for side effects. Be sure to keep all doctor and lab appointments.
