Quinora Oral Warning

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 infrequently cause new serious (possibly fatal) irregular heartbeats.

Quinora Oral Side Effects

Diarrhea, nausea, vomiting, loss of appetite, stomach pain/cramps, or a burning feeling in throat or chest (e.g., heartburn) may occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.

Remember that your doctor has prescribed this medication because he or she 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.

Seek immediate medical attention if any of these unlikely but serious side effects occur:

severe dizziness
fainting
sudden change in heartbeat (faster/slower/more irregular)

Tell your doctor immediately if any of these unlikely but serious side effects occur:

vision changes
eye pain
muscle pain
unusual sweating or shakiness (signs of low blood sugar)

Tell your doctor immediately if any of these rare but very serious side effects occur:

unexplained fever/signs of infection (e.g., persistent sore throat)
easy bruising/bleeding
extreme tiredness

persistent nausea/vomiting
yellowing eyes/skin
lupus-like symptoms (joint/muscle pain, chest pain, change in the amount of urine)

A very serious allergic reaction to this drug is rare. However, seek immediate medical attention if you notice any symptoms of a serious allergic reaction, including:

rash
itching
swelling
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.
