Whether to add another blood pressure medicine depends on your current readings and how well they are controlled with the present treatment. You should consult your doctor, who can review your BP records and decide if dose adjustment or an additional medicine is needed.

A lower blood pressure (diastolic) can be due to stress, anxiety, excess salt intake, poor sleep, or irregular medication use. Regularly monitoring your BP, reducing salt intake, managing stress, and consulting your doctor can help identify the cause and correct it.
