Phentermine diet pills...are they safe and effective?

I think the only non prescription alternative to Phentermine are effective, like this: http://www.phenterminedispensary.com/

Also, from where can I order them online so as to buy the genuine article as I have seen wildly differing prices which makes me think someone is offering fakes !

Finally, I have found an informative and sensible website to ask about Phentermine ! My question is - does Phentermine 37.5mg have less side effects ?

I just visited my doctor, she advised me on phendermine 37.5 mg for the weightloss. I am very confused if I could really go on this drug.Is there any special diet to be followed while we are on this drug.

Phentermine is a good product but I don't really recommend it because it contains amphetamine. The chemical Amphetamine can be quite addictive even after you stop taking phentermine. So it is highly recommended that when takes it they gradually get off of it..because there have been cases where people grew quite dependent on the drug and was basically addicted to it. I've actually heard of a drug called Phentramin-D which is a Phentermine replacement it does not contain Amphetamine and has basically the same characteristics as Phentermine!

Phentermine is known to decrease the appetite. I am not very sure but it probably suppresses the appetite by acting on centers in the brain that control appetite. It is in combination with exercise and diet for the short-term treatment of obesity in individuals with a body mass index greater than or equal to 30 kg/m2 or greater than or equal to 27 kg/m2. It does have a risk factor for heart disease.

My sister's doctor prescribed phentermine and it also really worked for her. She lost 40 pounds while using the medicine and has now been off of it for about half a year and has continued to keep the weight off.

Her doctor was quite strict about how the medicine was used, in which people (the BMI of 30 is crucial) and for what time period. Over time, the medicine IS less effective, like Anon said, so it's not like most people would stay on it forever. I think she lost 20 pounds the first month, maybe 10 the second month, maybe 5 the 3rd and 4th months each, and then she went off of it. There are diminishing returns to being on it for a much longer period of time.

What was great about it was that it gave her motivation, support and a fresh start. To be able to see SOME results quickly gave her a boost in energy and in wanting to do well for herself. That in itself is important.

I think that by the time most doctors prescribe phentermine, they have patients that are in the obese category who just need some real help and motivation fairly quickly. Is it for everyone? No, especially because it does interact with other medicines. But used on the right people with the right doctors, it seems to be a very positive thing.

Has your friend considered a natural approach to weight loss?
I lost weight by a simple exercise program and sensible eating of healthy, non processed foods. This really is the best approach for weight loss for life. Drugs often have side effects and when you stop taking them, you are back to square one.
I wonder at doctors sometimes. The goal of weight loss is to be healthy and then Doc comes along and prescribes drugs rather than suggesting a healthy plan of action that is cheaper and more sustainable!
For some reason, we are convinced that we can't go it alone! We need chemicals or liposuction or a by pass. What about a bit of old fashioned exercise and eating smaller portions of healthy food?
