Quinidine Gluconate ER is a generic drug manufactured by Sun and Mylan. No brand-name alternative is available at this time.
Quinidine Gluconate ER is a generic extended-release prescription drug that treats or prevents atrial fibrillation and atrial flutter. Both are irregular (arrhythmia) or fast heartbeats (tachycardia) caused by disorganized electrical signals in the top two chambers of the heart (the atria). Atrial fibrillation and flutter are the most common type of irregular heartbeat diagnosed
Quinidine Gluconate ER is also used to reduce sustained and life-threatening fast heartbeats due to problems in the lower chambers (ventricles) of the heart. It is not used for other irregular heartbeats in the ventricles.
Quinidine Gluconate ER interferes with the electrolyte mechanisms that are responsible for electrical signals in the nerves and muscles of the heart. By interfering with nerve signals and muscle contractions, Quinidine Gluconate ER slows the heartbeat and returns it to a more normal rhythm.
Quinidine Gluconate ER is taken as a tablet. The dose and schedule will depend on the severity of the underlying condition.
Common physical side effects include, but are not limited to, nausea, vomiting, diarrhea, decreased appetite, stomach pain, heartburn, lightheadedness, headache, fatigue, chest pain, and tremor. Serious but rare side effects include liver problems.
Quinidine is chemically similar to quinine, which can be toxic even in a single dose. Contact your doctor immediately if you experience symptoms of quinine poisoning such as ringing in the ears, hearing problems, blurred vision, confusion, and headache. Mental and mood changes include nervousness. Allergic reactions are very rare. This is not a complete list of side effects and others may occur. If you have questions about side effects, consult with your doctor or pharmacist.
