Metformin Side Effects: What Nurses Should Know

When dealing with a client who has a new prescription for metformin, it's essential for nurses to be aware of the potential side effects of this medication. Metformin is a commonly prescribed oral antidiabetic drug used to treat type 2 diabetes. As a nurse, it's crucial to educate clients about the possible side effects of metformin to ensure they understand the medication's benefits and risks.

Common Side Effects of Metformin

While metformin is generally well-tolerated, some clients may experience side effects. The most common side effects of metformin include:

Diarrhea: Metformin can cause gastrointestinal side effects, including diarrhea, abdominal pain, and nausea. These side effects are usually mild and temporary, but in some cases, they can be severe.
Vitamin B12 deficiency: Long-term use of metformin can lead to a deficiency in vitamin B12, which is essential for the production of red blood cells. This deficiency can cause symptoms such as fatigue, weakness, and neurological problems.
Lactic acidosis: Metformin can cause a rare but serious side effect called lactic acidosis, which occurs when the body produces too much lactic acid. This condition can be life-threatening if left untreated.

Headache: Some clients may experience headaches as a side effect of metformin.

Hypoglycemia: Metformin can cause hypoglycemia (low blood sugar) when used in combination with other diabetes medications.
Weight loss: Metformin can cause weight loss in some clients, particularly those with a high body mass index (BMI).
Muscle pain: Some clients may experience muscle pain or weakness as a side effect of metformin.
