Diclofenac is a nonsteroidal anti-inflammatory drug (NSAID) commonly used to treat pain, inflammation, and fever. As with any medication, it's essential to be aware of the potential side effects of diclofenac to ensure safe and effective treatment. In this article, we'll explore the common and rare side effects of diclofenac, as well as provide guidance on how to minimize the risk of adverse reactions.
Diclofenac works by inhibiting the production of prostaglandins, which are hormone-like substances that cause pain and inflammation in the body. While diclofenac is generally well-tolerated, it's not without risks. The side effects of diclofenac can range from mild to severe and may affect various parts of the body, including the gastrointestinal tract, cardiovascular system, and kidneys.
Common Side Effects of Diclofenac
The most common side effects of diclofenac are typically mild and temporary. They may include:
- Gastrointestinal upset, such as nausea, vomiting, and diarrhea
- Abdominal pain or discomfort
- Headache
- Dizziness or lightheadedness
- Fatigue or tiredness
These side effects usually resolve on their own within a few days of starting treatment. However, if they persist or worsen, it's crucial to consult with your healthcare provider.
Gastrointestinal Side Effects
Diclofenac can cause gastrointestinal side effects, including:
| Side Effect | Frequency |
