Phentermine comes as a tablet, capsule or orally disintegrating tablet (ODT). Depending on the manufacturer, exact appearance of the medication differs.
For example, Adipex – one of the most popular brands of phentermine in the US – is a white tablet with blue specs. However, generic 15mg capsules of phentermine are typically yellow and gray. The now-discontinued brand Ionamin was also a yellow capsule.
