What Is Phentermine HCl?
Phentermine hydrochloride is a prescription sympathomimetic amine anorexiant — meaning it suppresses appetite by acting on the central nervous system. It is one of the most widely prescribed weight-loss medications in the United States and has been FDA-approved for obesity management since 1959. It is classified as a Schedule IV controlled substance.
How Does Phentermine Work?
Phentermine stimulates the release of norepinephrine in the hypothalamus — the brain region that regulates hunger and energy balance. Elevated norepinephrine activates the fight-or-flight response, which suppresses appetite signals. The result is reduced hunger, earlier satiety, and lower calorie intake throughout the day. Phentermine also slightly increases metabolic rate.
Who Qualifies for Phentermine?
Phentermine is approved for short-term use (up to 12 weeks) in adults who:
- Have a BMI ≥ 30 kg/m² (obesity), or
- Have a BMI ≥ 27 kg/m² with a weight-related comorbidity (hypertension, type 2 diabetes, dyslipidemia)
- Have not achieved adequate weight loss through diet and exercise alone
It should be used as part of a comprehensive program including behavioral changes, dietary modification, and physical activity.
Dosage Overview
- Phentermine HCl capsules/tablets: 15 mg, 30 mg, or 37.5 mg — typically taken once daily before breakfast or 1–2 hours after breakfast
Taking phentermine later in the day can cause insomnia. Some providers prescribe lower doses to minimize side effects while maintaining appetite suppression.
Side Effects and Precautions
Common side effects include increased heart rate, elevated blood pressure, dry mouth, insomnia, nervousness, and headache. Phentermine is not appropriate for people with heart disease, uncontrolled hypertension, hyperthyroidism, or glaucoma. It is a Schedule IV controlled substance and can be habit-forming if misused.
