What is a generic medication?

Generic medications are significantly discounted copies of brand name medication that have the same active ingredients, intended use, dosage, side effects, effects, and route of administration as the original brand name medication.

Qualaquin Drug Information

  • Qualaquin Overview

    Qualaquin is used alone or with other medication to treat malaria caused by mosquito bites in countries where malaria is common. Malaria parasites can enter the body through these mosquito bites, and then live in body tissues such as red blood cells or the liver. Qualaquin is used to kill the malaria parasites living inside red blood cells. In some cases, you may need to take a different medication (such as primaquine) to kill the malaria parasites living in other body tissues. Both drugs may be needed for a complete cure and to prevent the return of infection (relapse). Quinine belongs to a class of drugs known as antimalarials. It is not used for the prevention of malaria. The United States Centers for Disease Control provide updated guidelines and travel recommendations for the prevention and treatment of malaria in different parts of the world. Discuss the most recent information with your doctor before traveling to areas where malaria occurs.

  • Qualaquin Warnings

    The US Food and Drug Administration (FDA) warns that quinine should not be used to treat leg cramps. It has not been shown to work for this use and may cause serious side effects. Consult your doctor or pharmacist for more details.

  • How to Use Qualaquin

    Read the Medication Guide and, if available, the Patient Information Leaflet provided by your pharmacist before you start taking quinine and each time you get a refill. If you have any questions, ask your doctor or pharmacist. Take Qualaquin by mouth, with food to decrease upset stomach, exactly as prescribed by your doctor. Qualaquin is usually taken every 8 hours for 3 to 7 days or as directed by your doctor. Take Qualaquin 2 to 3 hours before or after taking antacids containing aluminum or magnesium. These products bind with quinine, preventing your body from fully absorbing the drug. Dosage and length of treatment are based on your medical condition, country where you were infected, other medications you may be taking for malaria, and your response to treatment. The dosage in children is also based on weight. It is very important to continue taking Qualaquin (and other malaria medications) exactly as prescribed by your doctor. Do not take more or less of Qualaquin than prescribed. Do not skip any doses. Continue to take Qualaquin until the full prescribed amount is finished, even if symptoms disappear after a few days. Skipping doses or stopping the medication too early may make the infection more difficult to treat and result in a return of the infection. Qualaquin works best when the amount of drug in your body is kept at a constant level. Therefore, take Qualaquin at evenly spaced intervals. To help you remember, take it at the same times each day. Tell your doctor if you do not start feeling better after 1-2 days of starting Qualaquin. If your fever returns after completing this prescription, contact your doctor so that he/she can determine whether the malaria has returned.

  • Qualaquin Precautions

    Before taking quinine, tell your doctor or pharmacist if you are allergic to it; or to quinidine or mefloquine; or if you have any other allergies. Qualaquin may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details. Before using Qualaquin, tell your doctor or pharmacist your medical history,previous serious side effects with quinine (such as blood problems), family/personal history of a certain enzyme problem (glucose-6-phosphate dehydrogenase deficiency-G6PD), a certain eye nerve problem (optic neuritis), hearing problems (such as ringing in the ears), a certain nerve/muscle disease (myasthenia gravis), heart rhythm problems (such as atrial fibrillation/flutter), kidney problems, liver problems. Qualaquin may make you dizzy or blur your vision. Alcohol or marijuana (cannabis) can make you more dizzy. Do not drive, use machinery, or do anything that needs alertness or clear vision until you can do it safely. Limit alcoholic beverages. Talk to your doctor if you are using marijuana (cannabis). Before having surgery, tell your doctor or dentist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products). Quinine may cause a condition that affects the heart rhythm (QT prolongation). QT prolongation can rarely cause serious (rarely fatal) fast/irregular heartbeat and other symptoms (such as severe dizziness, fainting) that need medical attention right away. The risk of QT prolongation may be increased if you have certain medical conditions or are taking other drugs that may cause QT prolongation. Before using quinine,certain heart problems (heart failure, slow heartbeat, QT prolongation in the EKG), family history of certain heart problems (QT prolongation in the EKG, sudden cardiac death). Low levels of potassium or magnesium in the blood may also increase your risk of QT prolongation. This risk may increase if you use certain drugs (such as diuretics/"water pills") or if you have conditions such as severe sweating, diarrhea, or vomiting. Talk to your doctor about using quinine safely. Older adults may be more sensitive to the side effects of Qualaquin, especially QT prolongation (see above). During pregnancy, Qualaquin should be used only when clearly needed. Discuss the risks, benefits, and treatment options with your doctor. Untreated malaria is a serious condition that can harm both a pregnant woman and her unborn baby. Qualaquin passes into breast milk. However, Qualaquin is unlikely to harm some nursing infants. Your doctor will test your infant for a certain enzyme deficiency (glucose-6-phosphate dehydrogenase deficiency-G6PD) before you breast-feed. Consult your doctor before breast-feeding.

  • Qualaquin Misdose

    If you miss a dose of Qualaquin, take it as soon as you remember. If more than 4 hours has passed since the missed dose, skip the missed dose. Take your next dose at the regular time. Do not double the dose to catch up.

  • Qualaquin Interactions

    See also How to Use section. Drug interactions may change how your medications work or increase your risk for serious side effects. This document does not contain all possible drug interactions. Keep a list of all the products you use (including prescription/nonprescription drugs and herbal products) and share it with your doctor and pharmacist. Do not start, stop, or change the dosage of any medicines without your doctor's approval."blood thinners" (such as warfarin), penicillamine. Other medications can affect the removal of quinine from your body, which may affect how quinine works. Examples include cimetidine, erythromycin, ketoconazole, phenytoin, rifampin, HIV protease inhibitors (such as lopinavir, ritonavir), urinary alkalinizers such as sodium bicarbonate, among others. Qualaquin can slow down the removal of other medications from your body, which may affect how they work. Examples of affected drugs include desipramine, digoxin, certain "statin" drugs (atorvastatin, lovastatin, simvastatin), phenobarbital, among others. Many drugs besides quinine may affect the heart rhythm (QT prolongation), including amiodarone, dofetilide, mefloquine, pimozide, procainamide, quinidine, sotalol, macrolide antibiotics (such as erythromycin), among others. Therefore, before using quinine, report all medications you are currently using to your doctor or pharmacist. Cimetidine is a nonprescription drug that is commonly used to treat extra stomach acid (such as heartburn, ulcers). Because cimetidine and aluminum/magnesium antacids may interact with quinine, ask your pharmacist about other products to treat extra stomach acid. Quinine is very similar to quinidine. Do not use medications containing quinidine while using quinine. Qualaquin may interfere with certain laboratory tests (including certain urine tests for catecholamines, protein, steroids), possibly causing false test results. Make sure laboratory personnel and all your doctors know you use Qualaquin.
