Can you drink Red Bull on phentermine? Can you take phentermine with energy drinks?

Red bull may also have a stimulant effect on the nervous system. When combined with stimulant medicines, it can induce dangerous side effects such as an elevated heart rate and high blood pressure. Because energy drinks generally include a combination of potent compounds such as caffeine, herbs, and other stimulants, mixing them with other drugs can be harmful, even fatal. Some people may purposefully mix energy drinks with drugs in order to enhance the effects of that medication.
