Metformin, while generally safe and effective, can cause side effects. The most common are gastrointestinal issues like nausea, diarrhea, vomiting, and abdominal bloating. These usually lessen as your body adjusts to the medication. Drink plenty of water and consider taking it with food to minimize these effects.
Less frequent but more serious side effects include lactic acidosis, a rare but potentially fatal build-up of lactic acid in the blood. This is more likely in individuals with kidney disease, liver disease, or heart failure. Regular monitoring of kidney function is recommended while taking metformin.
Vitamin B12 deficiency is another potential long-term consequence. Your doctor may recommend regular B12 level checks. A low B12 level can lead to fatigue and neurological problems.
Metformin can also interact with other medications, such as certain contrast dyes used in medical imaging. Always inform your doctor and pharmacist of all medications and supplements you are taking. Temporary cessation of metformin may be necessary before certain procedures.
Allergic reactions, although infrequent, can occur. Symptoms such as rash, itching, or swelling require immediate medical attention.
