Phentermine is a prescription weight loss drug that is used to suppress appetite. It is a stimulant and is similar to amphetamines. Phentermine is primarily used for short-term weight loss in obese individuals. The drug is typically prescribed alongside a reduced-calorie diet and regular exercise program. Phentermine is not recommended for long-term use due to its potential side effects and the risk of dependence.
How Phentermine Works
Phentermine works by suppressing appetite and increasing energy levels. The drug stimulates the release of neurotransmitters in the brain, such as norepinephrine and dopamine, which help to reduce hunger and increase feelings of fullness. This helps people to eat less and lose weight.
Phentermine also increases metabolism, which increases the rate at which the body burns calories. This can lead to weight loss, as the body is burning more calories than it is taking in. Phentermine is also believed to enhance the body's ability to burn fat, which can further aid in weight loss.
Phentermine is available in several different forms, including tablets, capsules, and extended-release capsules. The recommended dosage of phentermine varies depending on the form of the drug and the individual's weight loss goals.
For immediate-release tablets, the recommended dosage is typically 15-37.5 mg per day, taken once daily before breakfast or 1-2 hours after breakfast.
Extended-release capsules are typically taken once daily in the morning, with a recommended dosage of 15-30 mg.
It is important to follow the recommended dosage instructions and not exceed the prescribed amount of phentermine. Taking too much phentermine can increase the risk of side effects and may be dangerous.
Side Effects of Phentermine
Phentermine can cause several side effects, ranging from mild to severe. Common side effects include:
- Dry mouth
Less common but more severe side effects of phentermine include:
- High blood pressure
- Fast or irregular heartbeat
- Chest pain
- Shortness of breath
- Severe headache
- Vision changes
It is important to seek medical attention if any of these more severe side effects occur while taking phentermine.
Precautions When Taking Phentermine
Phentermine should be used with caution and under the guidance of a healthcare provider. The drug is not recommended for people with certain medical conditions, such as:
- High blood pressure
- Heart disease
- Overactive thyroid
- History of drug abuse
Phentermine may also interact with other medications, so it is important to inform healthcare providers of all medications being taken before starting phentermine.
Phentermine can also be habit-forming, so it should only be used for short-term weight loss goals and under the supervision of a healthcare provider.
