1. Monitor blood pressure closely in elderly patients on nifedipine, adjusting dosage with caution to avoid severe hypotension.

2. Initiate nifedipine at a low dosage in elderly due to reduced drug clearance and increased sensitivity to its effects.

3. Assess renal and hepatic function before prescribing nifedipine to elderly patients, as impaired function can affect drug metabolism.

4. Be vigilant for signs of edema or heart failure in elderly taking nifedipine, due to their susceptibility to volume overload.

5. Evaluate potential drug interactions with nifedipine in elderly patients, especially with medications affecting cardiovascular and renal systems.
