Metformin is a drug used to treat non-insulin-dependent diabetes in adults and children. It can be also prescribed to prevent this disease in people with a number of risk factors, treat polycystic ovaries and weight gain resulting from the use of antipsychotic medications. Unless told so by your doctor, do not combine metformin with other drugs to prevent dangerous interactions. You need to report a history or heart disease or liver disease to your doctor as these conditions can affect the efficiency of your treatment. Metformin side effects are: headache, gas, weakness, muscle pain, diarrhea, vomiting and stomach pain.
Lactic acidosis is a rare and dangerous side effect of metformin. If you experience the typical signs of lactic acidosis (muscle pain, cold feeling, shortness of breath, increased sleepiness, slow heart rate) seek emergency medical assistance as this condition can be fatal. Taking any other over-the-counter or prescription medication can change metformin effects. Do not start using any other drugs simultaneously with metformin without previously discussing it with your doctor. If you are pregnant or breastfeeding, your doctor needs to know about it before prescribing metformin.
