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.
