Hi, Welcome to icliniq.com. It would take anything between two to four weeks to get her blood pressure to a safer level (140/90 mmHg or less) if she takes her medicines regularly. Other activities you need are salt restricted diet (less than 2gm/day), daily walking normal and slightly brisk pace for 30-45 minutes. Increase potassium in diet, for example bananas and potassium containing salt. Do meditation, slow and deep breathing.
