Metformin Alert: Skin Yellowing Signals Liver Risk
17 May
Summary
- Metformin, a common diabetes drug, can cause rare but serious side effects.
- Yellowing of the skin or eyes (jaundice) may indicate liver complications.
- Seek immediate medical attention for jaundice or severe unwellness.
Millions worldwide rely on metformin, a common medication primarily used to manage type 2 and gestational diabetes. It also aids in preventing type 2 diabetes and treating certain fertility conditions.
While generally well-tolerated with minor side effects like nausea, metformin can, in rare instances (less than one in 10,000 people), cause severe reactions. The NHS highlights jaundice—yellowing of the skin or the whites of the eyes—as a critical sign of potential liver complications.
Patients experiencing jaundice or a general feeling of unwellness accompanied by extreme fatigue, rapid breathing, or a slow heartbeat must contact their doctor or seek emergency services immediately. The drug can also lead to vitamin B12 deficiency and low blood sugar, requiring medical consultation.
In very rare cases, serious allergic reactions like anaphylaxis can occur, presenting with symptoms such as severe itching, swelling, or blistering skin. Anyone experiencing these severe allergic signs should call emergency services without delay.
