Precautions While Using This Medicine

Your doctor should check your progress at regular visits to make sure the medicine is working properly.

Do not stop taking this medicine without first checking with your doctor. Stopping suddenly may cause a serious change in heart function .

Dizziness, lightheadedness, or fainting may occur, especially when you get up from a lying or sitting position . This is due to lowered blood pressure. Getting up slowly may help. This effect does not occur often at doses of disopyramide usually used; however, make sure you know how you react to this medicine before you drive, use machines, or do anything else that could be dangerous if you are not alert . If the problem continues or gets worse, check with your doctor.

Disopyramide may rarely cause hypoglycemia (low blood sugar) in some people . (See the Side Effects of This Medicine section below.) If these signs appear, eat or drink a food containing sugar and call your doctor right away .

This medicine may cause blurred vision or other vision problems. If any of these occur, do not drive, use machines, or do anything else that could be dangerous if you are not able to see well .

Disopyramide may cause dryness of the eyes, mouth, and nose. For temporary relief of mouth dryness, use sugarless candy or gum, melt bits of ice in your mouth, or use a saliva substitute. However, if dry mouth continues for more than 2 weeks, check with your medical doctor or dentist. Continuing dryness of the mouth may increase the chance of dental disease, including tooth decay, gum disease, and oral yeast infections.

This medicine often will make you sweat less, allowing your body temperature to increase. Use extra care not to become overheated during exercise or hot weather while you are taking this medicine , since becoming overheated could possibly result in heatstroke.
