Taking more metformin than prescribed significantly increases your risk of lactic acidosis, a serious and potentially fatal condition. This happens because metformin lowers blood sugar, and excessive amounts can overwhelm the body’s ability to process it, leading to a dangerous buildup of lactic acid in the blood.
Gastrointestinal issues, such as nausea, vomiting, and diarrhea, become far more pronounced at higher doses. Expect these side effects to be more severe and frequent than you might experience with a standard prescription.
Vitamin B12 deficiency is another potential consequence of exceeding the recommended metformin dose. Metformin interferes with B12 absorption, and higher doses exacerbate this effect, potentially leading to neurological problems over time. Regular monitoring of B12 levels is crucial if you’re taking metformin.
Kidney problems can worsen with excessive metformin use. Metformin is primarily excreted through the kidneys, and high doses can strain kidney function, particularly in individuals with pre-existing kidney disease. Regular kidney function tests are necessary.
Hypoglycemia, or dangerously low blood sugar, is a risk at any dose of metformin, but significantly increases with overuse. Symptoms include dizziness, confusion, sweating, and weakness. Immediate medical attention is required.
Always follow your doctor’s instructions regarding metformin dosage. Never adjust your dosage without consulting your physician. Your doctor can help you manage your diabetes safely and effectively.
