Before taking this drug for treatment of an irregular heartbeat, you should discuss your risks and benefits of treatment with your doctor or pharmacist. This drug should be used only in carefully selected patients. Many heart drugs like quinidine (antiarrhythmics) are very effective, but they can rarely cause new serious (possibly fatal) irregular heartbeats.

Diarrhea, nausea, vomiting, loss of appetite, stomach pain/cramps, or a burning feeling in throat or chest (such as heartburn) may occur. If any of these effects last or get worse, tell your doctor or pharmacist promptly. Remember that this medication has been prescribed because your doctor has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects. Tell your doctor right away if you have any serious side effects, including: vision changes, eye pain, muscle pain, signs of low blood sugar (such as unusual sweating, shakiness), signs of infection (such as sore throat that doesn't go away, fever, chills), easy bruising/bleeding, extreme tiredness, signs of liver problems (such as nausea/vomiting that doesn't stop, dark urine, yellowing eyes/skin), aching/swollen joints. Get medical help right away if you have any very serious side effects, including: severe dizziness, fainting, sudden change in heartbeat (faster/slower/more irregular). A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing. One type of reaction (cinchonism) can occur after even a single dose of this drug. Contact your doctor of pharmacist promptly if you notice symptoms such as ringing in the ears, sudden hearing problems, headache, blurred vision, confusion. Your dosage may need to be adjusted. Certain long-acting brands of quinidine may appear as a whole tablet in the stool. This is the empty shell left after the medicine has been absorbed by the body. It is harmless.
