What is Adipex-P

PhentermineThe Generic name of this drug
Treatment SummaryPhentermine is a medication used to treat obesity. It was first introduced in 1959 and became popular in 1960. It is a chemical relative of amphetamine, but is not known to be addictive and has been classified as a drug with low abuse potential. Phentermine was approved for short-term weight management in 1959, but it was later discontinued after reports of abnormal valve growth in nearly 30% of consumers. In 2012, phentermine was approved alone and in combination with topiramate for a new weight loss treatment that requires lower doses of phentermine.

Effectiveness

How Adipex-P Affects PatientsPhentermine is a drug used to help with weight loss. It works by reducing appetite and increasing resting energy expenditure. Studies have shown that people taking phentermine lose an average of 3.6 kg over 2-24 weeks, and can maintain the weight loss after treatment is stopped. Unlike other amphetamines, phentermine does not cause any stimulation, elevated blood pressure, or other side effects.
How Adipex-P works in the bodyPhentermine works by releasing a chemical called noradrenaline in the brain. This chemical stimulates certain receptors in the body, creating a "fight-or-flight" response which suppresses the hunger signal. It also weakly inhibits a chemical called monoamine oxidase, though this doesn't have a major effect.

Adipex-P Reviews: What are patients saying about Adipex-P?

Adipex-P for Weight Loss Management for an Obese Person
I started this treatment when I was 18 years old, and it really helped me lose weight. I didn't have any major side effects, other than feeling thirsty and my heart rate being pretty fast at times. Unfortunately, I gained the weight back after a year of college. But I'm starting the treatment again now and am hopeful that I'll be able to lose the weight and keep it off this time around.

Adipex-P for Overweight
Adipex has been a godsend. It completely suppressed my appetite and helped me lose 46lbs in just two months. I'm excited to see how much more weight I can lose now that I've started taking it again.

Adipex-P for Overweight
I took this years ago and it was very effective. I went from 193 pounds to 119 pounds within several months while following a 1200 calorie diet and doing short workouts 2-3 days per week. I was able to keep the weight off for 8 years by halving the dose and taking the pill every 2-3 days for 30 days.

Adipex-P for Overweight
I've been doing this meditation for about a month now, and I've already lost 21 pounds! When I first started, I had some side effects, but they went away after a little while. I'm really hoping to lose another 128 pounds, but even if I don't, I'm still happy with the progress I've made so far.

Adipex-P for Weight Loss Management for Overweight Person with BMI 27 to 29 and Weight-Related Comorbidity
This medication was incredibly effective for me. I started at 238lbs and after three weeks of taking it, I had already lost 20lbs. However, I would not recommend taking it later than 8am as it will make it hard to sleep at night. Other than that, I've been really happy with the results and am currently on my second round.
