Honeydew saidSide effects
deltalimen saidI'm eating phentermine out of a PEZ dispenser. It gives the illusion I'm eating candy, but the jokes on everyone else.
Good Lord... Just wait until you stop it. I wanna see how fun that is.
Generally, phentermine appears to be relatively well tolerated. It can produce side effects consistent with its catecholamine-releasing properties, e.g., tachycardia (increased heart rate) and elevated blood pressure, but the incidence and magnitude of these appear to be less than with the amphetamines. Because phentermine acts through sympathomimetic pathways, the drug may increase blood pressure and heart rate. It may also cause palpitations, restlessness, and insomnia. Additionally, phentermine has the potential to cause psychological dependence.More common
