5 Things To Know About Phentermine

Phentermine HCL

  1. How it works
    Phentermine causes the brain to stimulate the adrenal glands to release norepinephrine, a neurotransmitter which signals a fight-or-flight response, reducing hunger.
  2. Prescriptions
    As phentermine has a pharmacology similar to amphetamine, it is classified as a controlled substance and is therefore only available on prescription.
  3. Combinations
    The two most commonly encountered phentermine combinations are Phen-Pro, which is a combination of phentermine and a low dose of an anti-depressant such as Prozac, and Qsymia, a combination of phentermine and topiramate, an anticonvulsant with weight loss side effects.
  4. Withdrawal Symptoms
    The most common withdrawal symptoms are fatigue, weight gain, insomnia, and low mood.
  5. The Phentermine Alternative
    For those people who do not have a phentermine prescription, or similarly, for those who have tried phentermine and found the side effects to be intolerable, Phen Caps offer a great solution.
