Phentermine is available in several oral dosage forms, primarily as capsules and tablets. Common strengths include 8 mg, 15 mg, 30 mg, and 37.5 mg [1][2].
What is Phentermine prescribed for?
Phentermine is a stimulant medication approved for short-term management of obesity, typically in conjunction with diet and exercise [3]. It works by affecting the central nervous system to decrease appetite [3].
How does Phentermine work?
Phentermine is a sympathomimetic amine, meaning it mimics the effects of adrenaline and noradrenaline in the body. It stimulates the hypothalamus in the brain, which helps to reduce appetite and increase metabolism. This can lead to a decrease in food intake and subsequent weight loss [4].
How long does Phentermine treatment typically last?
Phentermine is generally prescribed for short-term use, often for up to 12 weeks. This is because its effectiveness for weight loss may decrease over time, and the risk of side effects can increase with prolonged use. However, in some cases, a healthcare provider may extend treatment if the benefits outweigh the risks [3].
What are the potential side effects of Phentermine?
Common side effects of phentermine include dry mouth, restlessness, insomnia, and changes in taste. More serious side effects can involve increased blood pressure, heart palpitations, and psychiatric symptoms. It is important to discuss any concerns with a healthcare provider [3].
Are there different types of Phentermine formulations?
Beyond immediate-release capsules and tablets, some formulations of phentermine are designed for extended release, which can allow for once-daily dosing and potentially smoother effects throughout the day. These are often combined with other medications, such as topiramate, to enhance weight loss and manage side effects [4].
