How should I take quinidine?
Take quinidine exactly as directed by your doctor. If you do not understand these directions, ask your pharmacist, nurse, or doctor to explain them to you.
 | Take each dose with a full glass of water. |
 | Quinidine may be taken with food to lessen stomach upset. |
 | Do not crush, chew, or break any extended- or sustained-release formulations of quinidine. Swallow them whole. If you are not sure whether you have a long-acting form of quinidine, ask your pharmacist, nurse, or doctor. |
 | Do not skip doses or change your dosing schedule without talking to your doctor. Changing your schedule could make your condition worse. |
It is important to take quinidine regularly to get the most benefit.
Your doctor may want you to have blood tests or other medical evaluations during treatment with quinidine to monitor progress and side effects.
Grapefruit and grapefruit juice may interact with quinidine. The interaction could lead to potentially adverse effects. You should discuss the use of grapefruit and grapefruit juice with your doctor. Do not increase or decrease the amount of grapefruit products in your diet without first talking to your doctor.
