Metformin, commonly prescribed for managing type 2 diabetes and polycystic ovary syndrome (PCOS), is generally safe but may cause some side effects. Commonly reported issues include gastrointestinal symptoms such as diarrhea, nausea, and stomach pain. In rare cases, metformin can lead to a serious condition called lactic acidosis, though this risk is low for most patients. Other potential side effects might involve vitamin B12 deficiency or changes in taste perception. It's important to start with a low dose and gradually increase under medical supervision to minimize these effects. Always consult healthcare providers about any side effects experienced while on metformin.
