• Monitoring: Regularly monitor blood glucose levels and kidney function, as metformin is excreted by the kidneys.
• Medical History: Inform your doctor if you have a history of kidney disease, liver disease, heart failure, or if you consume excessive alcohol.
• Lactic Acidosis Risk: Be aware of the symptoms of lactic acidosis (such as rapid breathing, muscle pain, abdominal pain, dizziness, and irregular heartbeat) and seek immediate medical attention if they occur. The risk is higher in people with kidney or liver problems, severe infections, or dehydration.
• Surgery and Radiologic Procedures: Inform your healthcare provider if you are scheduled for surgery or certain radiologic procedures that use iodinated contrast dyes, as these can increase the risk of lactic acidosis. You may need to temporarily stop taking metformin.
• Vitamin B12 Levels: Long-term use of metformin can lead to decreased absorption of vitamin B12, so periodic monitoring of vitamin B12 levels is recommended.
• Diet and Exercise: Follow a balanced diet and exercise plan as advised by your healthcare provider to help manage your diabetes effectively.
