Phentermine and High Blood Pressure

 Phentermine is a prescription weight loss medicine approved for short-term use. It is generally recommended that you talk to your healthcare provider before taking this drug if you have:
 
 
  • Agitation

There is a known link between phentermine and high blood pressure. The weight loss medication can potentially increase your heart rate and blood pressure. This can cause problems, especially if you already have high blood pressure or heart problems. You should not take phentermine products if you have moderate to severe high blood pressure.
