Cordarone is used in treating irregularities in heart beat and other conditions if prescribed by your doctor.
Following the dosage instructions of your doctor is the best way to use any medication. If you are unsure or do not remember the instructions then you may read the medicine label for more detailed information.
You may choose to take Cordarone with a meal to avoid an upset stomach or without one. You must avoid grapefruit while taking Cordarone.
Please drink a full glass of water with Cordarone.
It is very important that you complete the dosage schedule and do not interrupt it in between without seeking prior consultation from your doctor.
Taking your medication at the same time each day is a tried and tested method to avoid missing any doses.
Despite your best attempts at remembering, if you still miss out on a dose, then take it as soon as you remember about it. But keep in mind that you will have to adjust your next dose by spacing it out by 4 to 5 hours. If this is not possible, then the best thing to do would be to skip the missed dose and continue with your normal dosage schedule.
Never try to compensate for the missed dose by taking a double dose together. It may cause adverse effects.
Store Cordarone at room temperature (read medicine label if unsure). Always keep it in a cool dark place that is not directly exposed to sources of heat or moisture and sunlight. Protect it from kids and pets.
