WARNING

Quinidine is one antiarrhythmic medication that may raise your risk of dying. If you have cardiac disease, such as a valve issue or heart failure, let your doctor know (HF; condition in which the heart cannot pump enough blood to other parts of the body). Call your doctor right away if you have any of the following symptoms: heart palpitations or chest pain

Consult your doctor about the dangers of quinidine use. Quinidine has not been demonstrated to extend the lives of those without life-threatening arrhythmias, and it may even raise the risk of developing arrhythmias (irregular heartbeats).

Why is this medication prescribed?

For some types of irregular heartbeats, quinidine is utilised. Antiarrhythmic medications, which include quinidine, are a group of drugs. Your heart becomes stronger against irregular activity as a result of how it works.

How should this medicine be used?

Quinidine is available in oral tablet form (quinidine sulphate) and extended-release (long-acting) tablet form (quinidine gluconate). Tablets of quinidine sulphate are typically given every six hours. It is typical to take extended-release quinidine gluconate pills every 8 to 12 hours. Take quinidine every day at roughly the same time. Ask your doctor or pharmacist to explain any instructions on your prescription label that you are unsure about following. Follow the quinidine directions exactly. Never take it in larger or less amounts or more frequently than directed by your doctor.

It is possible to divide the extended-release tablet in two. Do not chew or crush the tablets; instead, swallow them whole or in half.

Quinidine aids in managing your illness but cannot treat it. Even if you are feeling fine, keep taking quinidine. Quinidine should not be stopped without first consulting your doctor.

Other uses for this medicine

Malaria is sometimes treated with quinoidine. The dangers of using this drug for your illness should be discussed with your doctor.

What special precautions should I follow?

Before taking quinidine,

  • If you have an allergy to quinidine, quinine, or any other medications, tell your doctor right away.
  • Inform your doctor and pharmacist about any additional prescription and over-the-counter drugs, vitamins, and dietary supplements you are currently taking or intend to take. Incorporate any of the following: antidepressants, acetazolamide, amiodarone (Nexterone, Pacerone), felodipine, nicardipine (Cardene), nifedipine (Adalat, Procardia), nimodipine, or verapamil (Calan, Covera, Verelan, in Tarka), calcium channel blockers (such as diltiazem, Cartia, Diltzac, etc. Digoxin (Lanoxin), diuretics (‘water pills’), methazolamide, mexiletine, phenobarbital (Dilantin, Phenytek), phenytoin (Dilantin, Phenytek), propranolol (Hemangeol, Inderal, Innopran), sodium bicarbonate (Arm & Hammer Baking Soda, in Zegerid OTC), and warfarin are some examples of (Coumadin, Jantoven). Your physician might need to adjust the dosage of your drugs or keep a close eye on you for side effects. Tell your doctor about all of the medications you are taking, even any not on this list, since many other drugs may also interact with quinidine.
  • Inform your doctor if you have heart block, immune thrombocytopenia (ITP; idiopathic thrombocytopenic purpura; a chronic condition that may cause easy bruising or bleeding due to an abnormally low number of platelets in the blood), or myasthenia gravis. Heart block is a condition in which electrical signals are not normally passed from the upper chambers of the heart to the lower chambers (a disorder of the nervous system that causes muscle weakness). Your physician might advise against taking quinidine.

Keep this medication tightly closed in the original container and out of the reach of children. Keep it away from excessive heat and moisture at room temperature (not in the bathroom).

Unused prescriptions must be disposed of carefully to prevent pets, kids, and other people from ingesting them. You should not, however, dispose of this medication in the toilet. Instead, utilising a medicine take-back programme is the easiest approach to get rid of your medication. To find out about take-back programmes in your area, speak with your pharmacist or the garbage/recycling department in your city. If you do not have access to a take-back programme, see the FDA’s Safe Disposal of Medications website at http://goo.gl/c4Rm4p for additional information.

Although many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and are simple for young children to open, it is crucial to keep all medications out of sight and out of reach of children. Always lock safety caps and promptly stash medication up and away from young children where it is out of their sight and reach to prevent poisoning. http://www.upandaway.org
