Will diclofenac sodium cause fluid retention in older people?

Yes, diclofenac sodium can cause fluid retention, particularly in older adults. This population may be more susceptible to the side effects of nonsteroidal anti-inflammatory drugs (NSAIDs) due to age-related changes in kidney function and fluid balance. Fluid retention can lead to increased blood pressure and exacerbate conditions like heart failure. Therefore, careful monitoring and consultation with a healthcare provider are recommended for older individuals prescribed this medication.
