How should I take metformin and repaglinide (PrandiMet)?
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.
Metformin and repaglinide is usually taken 2 or 3 times daily, within 15 minutes before eating a meal. Follow your doctor's instructions. If you skip a meal, do not take your dose of metformin and repaglinide. Wait until your next meal.
Your blood sugar will need to be checked often, and you may need other blood tests at your doctor's office. Visit your doctor regularly.
Know the signs of low blood sugar (hypoglycemia) and how to recognize them: headache, hunger, weakness, sweating, tremors, irritability, or trouble concentrating.
Always keep a source of sugar available in case you have symptoms of low blood sugar. Sugar sources include orange juice, glucose gel, candy, or milk. If you have severe hypoglycemia and cannot eat or drink, use an injection of glucagon. Your doctor can give you a prescription for a glucagon emergency injection kit and tell you how to give the injection.
Check your blood sugar carefully during a time of stress or illness, if you travel, exercise more than usual, drink alcohol, or skip meals. These things can affect your glucose levels and your dose needs may also change.
Your doctor may want you to stop taking this medication for a short time if you become ill, have a fever or infection, or if you have surgery or a medical emergency.
Ask your doctor how to adjust your dose if needed. Do not change your medication dose or schedule without your doctor's advice.
Your doctor may have you take extra vitamin B12 while you are taking metformin and repaglinide. Take only the amount of vitamin B12 that your doctor has prescribed.
