Your current blood pressure readings of 115/70 mmHg to 105/60 mmHg are within or slightly below the normal range, indicating effective control by Olmesartan. However, do not adjust your medication dose without consulting your healthcare provider.

Key points to consider:

1. Do not change your medication dose on your own. Reducing the dose without medical advice can lead to uncontrolled blood pressure later.

2. Monitor for symptoms. If you experience dizziness, lightheadedness, or fainting, inform your doctor promptly.

3. Regular check-ups. Your doctor may want to review your blood pressure trends and overall health before making any changes.

4. Lifestyle factors. Continue healthy habits like a balanced diet, regular exercise, and avoiding excess salt.

Please schedule an appointment with your healthcare provider to discuss your blood pressure readings and medication. They can provide personalized advice and adjust your treatment safely if needed.
