Diclofenac is a common medicine. It helps reduce pain and inflammation. Many people use it for headaches, arthritis, or injuries. But, can it affect blood sugar levels? This is a question many ask. Let’s explore this together.

Many studies show diclofenac does not raise blood sugar levels. This is true for most people who do not have diabetes. For these individuals, taking diclofenac is safe regarding blood sugar. However, there are some exceptions.
Effects On People With Diabetes
For people with diabetes, diclofenac may affect blood sugar levels. Here are some points to consider:
