There is a very good reason why this question is one of the most frequently asked when Phentermine is in question. In fact there are two. The first one is that obesity is becoming more and more wide-spread, especially in the western world. The modern lifestyle is contributing to the growing tendency of people becoming obese and the percentage of people who are obese (not just overweight) has reached more than 20% in the US. Obesity is much more 
serious than some people think as it increases the chances for high blood pressure, high cholesterol, as well as diabetes which are all conditions that can have developments and can lead to episodes that might be life-threatening. The other reason why people are interested in whether they can start using Phentermine is that this medication is one of the most effective weight loss aids and that more and more people experience the beneficial effects of Phentermine.
We have started this website in order to give the people the information they need and we want to be as objective as we can. For this reason, we will not claim that Phentermine can be taken by absolutely anyone, as this is not true. However, it has to be said that the medication is well tolerated and that the large majority of people will be suitable for a Phentermine treatment that will aid in their weight loss program and melt away those extra few pounds that everyone is looking for when trying to lose weight.The first group of people who should not be taking Phentermine are people who are allergic to the medication or to any of its ingredients. These people are likely to develop allergic reactions to the medication and these reactions may be so severe that they might even be fatal if not treated immediately. Due to the fact that Phentermine may cause a slight increase in the blood pressure, people who have severely high blood pressure should also refrain from using Phentermine, as well as people with glaucoma, overactive thyroid, severe narrowing of blood vessels and people with blood vessel and heart diseases. It is possible that Phentermine will affect their conditions and the risk is considered too high for these people.
Also, if you have used medications such as MAO inhibitors, guanadrel, furazolidone, fanfluramine, dexfenfluramine or guanethidine in the last 14 days, you should also steer clear of Phentermine as the interaction between these medications and Phentermine may be very severe.
There are certain conditions that might also be affected by the use of Phentermine or that might affect your Phentermine regimen which is why you should discuss using Phentermine with your doctor if you have any of these. You will most likely still be able to take the medication, but your doctor will need to monitor your treatment more closely. These conditions include: high blood pressure, thyroid disorders and diabetes.
You will also most likely be discouraged from using Phentermine if you have been addicted to any drugs in the past as there is a possibility that you might become addicted to Phentermine, due to some of its properties. If you have any further questions and if you wish to be completely certain that your Phentermine will be risk-free, make sure you talk to your doctor.
