What should I discuss with my healthcare provider before taking quinidine (Quin-G)?
You should not take this medication if you have ever had an allergic reaction to quinidine or quinine (Qualaquin), including easy bruising or unusual bleeding. You should not take quinidine if you have myasthenia gravis or certain heart conditions, especially "AV block" (unless you have a pacemaker).
To make sure you can safely take quinidine, tell your doctor if you have any of these other conditions:
FDA pregnancy category C. It is not known whether quinidine will harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant while using this medication.
Quinidine can pass into breast milk and may harm a nursing baby. Do not use this medication without telling your doctor if you are breast-feeding a baby.
How should I take quinidine (Quin-G)?
Take exactly as prescribed by your doctor. Do not take in larger or smaller amounts or for longer than recommended. Follow the directions on your prescription label.
Your doctor may occasionally change your dose to make sure you get the best results.
Do not crush or chew an extended-release tablet. Swallow it whole. You may break the tablet in half if your doctor instructs you to.
If you need surgery, tell the surgeon ahead of time that you are using quinidine. You may need to stop using the medicine for a short time.
Ask your doctor how to adjust your quinidine dose if needed. Do not change your medication dose or schedule without your doctor's advice.
Use quinidine regularly to get the most benefit. Get your prescription refilled before you run out of medicine completely.
While using quinidine, you may need blood tests at your doctor's office. Visit your doctor regularly.
