Hormonal

Sympathomimetic obesity drugs (phentermine/topiramate, bupropion/naltrexone) increase heart rate and blood pressure, posing a potential cardiovascular risk despite weight loss benefits.

Sympathomimetic weight loss drugs can raise blood pressure and heart rate. If you have hypertension or heart conditions, these drugs may not be suitable, or require close monitoring.

GoodRefutesHIGH confidence
Like other sympathomimetic drugs, phentermine plus topiramate increases heart rate in clinical trials... Bupropion plus naltrexone increased heart rate and BP more than placebo.
