Description

Phentermine 37.5 mg is a prescription medication used primarily as an appetite suppressant to aid in weight loss. It is often prescribed as part of a comprehensive weight management plan that includes diet, exercise, and behavioral modification. Phentermine is a stimulant that affects the central nervous system to help reduce hunger and promote weight loss.

Active Ingredient

The active ingredient in Phentermine is phentermine hydrochloride. It is a sympathomimetic amine that functions similarly to amphetamines.

Mechanism of Action

Phentermine works by stimulating the release of neurotransmitters in the brain, specifically norepinephrine. This action influences the central nervous system to:

• Reduce Appetite: By altering neurotransmitter levels, phentermine helps to decrease feelings of hunger, making it easier for individuals to adhere to a reduced-calorie diet.
• Increase Energy Levels: It can enhance physical activity levels, indirectly supporting weight loss efforts.

Indications

Phentermine 37.5 mg is indicated for:

• Weight Management: Short-term management of obesity or overweight in conjunction with a reduced-calorie diet and exercise program. It is typically prescribed for patients with a Body Mass Index (BMI) of 30 or greater, or a BMI of 27 or greater with comorbid conditions such as hypertension or diabetes.

Dosage and Administration

• Weight Management: The usual dose of phentermine 37.5 mg is one tablet taken orally once daily, usually before breakfast or 1-2 hours after breakfast. The medication is generally prescribed for a short duration, typically 12 weeks, due to the risk of dependence and diminishing effectiveness over time.

Phentermine should be taken exactly as prescribed. It should not be used for longer than the recommended period due to potential risks of tolerance and dependence.

Side Effects

Common side effects include:

• Central Nervous System: Insomnia, restlessness, dizziness, and headache.
• Gastrointestinal: Dry mouth, constipation, and nausea.
• Cardiovascular: Increased heart rate, elevated blood pressure, and palpitations.
