Can I use phentermine if I have high blood pressure?
A history of high blood pressure is not an exclusionary condition to use of phentermine; however, blood pressure does need to be under adequate control (e.g., ideally systolic blood pressure <135 mmHg and diastolic blood pressure <85 mmHg) prior to beginning the program. We assess blood pressure at every visit, referring patients back to their primary care doctors for more adequate blood pressure control prior to their continuing in the program in the event it does become too high. However, as our results show, average blood pressure for participants in the program actually decreases from the first visit, and the number of patients who actually experience an increase in blood pressure as they progress through the program is quite small.
