In brief: Phentermine

While it is uncertain, a prospective surveillance study1 of 579 patients—205 with primary pulmonary hypertension and 374 with secondary pulmonary hypertension—showed no relation between primary pulmonary hypertension and Phentermine (odds ratio 0·6, 95% ci 0·2—2·2).

In brief: Yes

Pulmonary hypertension occurs after consumption of appetite suppressing drugs such as Fenfluramine & Dexfenfluramine which have been commonly prescribed with phentermine.
When used alone, it can still cause pulmonary hypertension & a lot of other serious side effects. Please consult your doctor to discuss the risks versus benefits before taking any medication.

In brief: Yes

It has been associated with higher incidence of pulmonary hypertension but it is dependent on how long you are on it and certain predisposing genetic factors.
