How should I take dofetilide (Tikosyn)?
Dofetilide is available only from a hospital or specialty pharmacy.
You will need to spend at least 3 days in a hospital setting when you first start taking dofetilide. This is so your heart rhythm and kidney function can be monitored in case the medication causes serious side effects.
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.
Dofetilide comes with patient instructions for safe and effective use. Follow these directions carefully. Ask your doctor or pharmacist if you have any questions.
You may take dofetilide with or without food.
Do not skip doses or stop taking dofetilide without first talking to your doctor. Stopping suddenly may make your condition worse. You may need to use less and less before you stop the medication completely.
Tell your doctor if you have a prolonged illness that causes severe diarrhea, vomiting, or heavy sweating. These conditions can cause an electrolyte imbalance, making it dangerous for you to use dofetilide.
Your blood pressure will need to be checked often. Your kidney function may also need to be checked with frequent blood tests. Visit your doctor regularly.
Store at room temperature away from moisture and heat.
