Metformin Unveiled: 10 Essential Side Effects You Need to Know

2. Lactic Acidosis: A Rare but Serious Concern

Lactic acidosis is a rare but potentially life-threatening side effect associated with metformin use. It occurs when lactate builds up in the bloodstream faster than it can be removed, leading to a dangerous drop in blood pH. Although the incidence is low, patients with kidney impairment, liver disease, or heart failure are at higher risk. Symptoms of lactic acidosis include muscle pain, difficulty breathing, abdominal pain, and confusion. Prompt medical attention is crucial if these symptoms arise. Regular monitoring of kidney function and adhering to prescribed doses can minimize the risk. While lactic acidosis is a serious concern, it is important to note that metformin is generally safe for the vast majority of users when used appropriately.
