If you have a prescription, you can get it filled at most pharmacies. 2.

As a brand, Adipex is often said to be more expensive than generic phentermine and some users have commented that Adipex is more effective than phentermine.

Phentermine and topiramate is an FDA-approved phentermine combination known as Qsymia. Some doctors choose to prescribe the two medications separately as opposed to prescribing the specific combination although this is essentially the same thing.10. How does phentermine help me lose weight?Contrary to what some people believe, phentermine is not a miracle pill which can help you lose weight without exercise or watching what you eat. Phentermine works by acting on the central nervous system to stimulate the release of neurotransmitters in our brain, including dopamine, epinephrine (adrenalin) and norepinephrine (noradrenalin). This causes phentermine to increase energy levels and alertness, reduce appetite and minimize cravings, therefore encouraging you to eat better and feel more motivated to establish a daily routine of activity to continue for the long term in order to reach and maintain your goals to lose weight with phentermine.11. When should I take phentermine?If your doctor decides that you are suitable for a phentermine prescription, he or she should provide you with clear instructions for when to take it. Phentermine should be taken at the beginning of the day and normally on an empty stomach. These instructions will vary with different phentermine brands, but you should take phentermine exactly as prescribed by your doctor and follow all directions on your prescription label. If you work shifts or during the night, then it is always a good idea to explain to your doctor how you need phentermine to fit in with your lifestyle, such as taking phentermine in the afternoon when you wake up, so that its effects are optimized when you most need them.12. What should I eat while taking phentermine?You should see the time that you are taking phentermine as the beginning of a healthier way of eating to continue in the long term. The best way to do this is to establish healthy eating habits, such as eating several smaller meals, drinking plenty of water, and to incorporate healthy, filling foods into your diet, such as these, which will also help to maximize the effects of phentermine. However, allowing yourself to still enjoy the foods you love in moderation will ensure that you do not feel deprived and slip up by bingeing as a result of an overly-strict eating regime. Remember that you need to eat to lose weight, so make sure to follow the guidance of your doctor about calorie intake and never eat less than 1200 calories in a day.13. Do I need to exercise to lose weight with phentermine?To maximize your results with phentermine then it is recommended that an important goal is to include some kind of physical activity in your healthier lifestyle. Exercise is an important part of your weight loss journey, not just to encourage weight loss and toning but it can help to boost energy levels, suppress appetite, minimize side effects and menstrual cramping, and boost your mood and outlook on life. As opposed to the list of things you can’t eat, exercise also gives you something that you can do to help your weight loss journey, as a pro-active way to improve your body. It’s important that you don’t see exercise as a chore or something you have to do; find an exercise you love, whether it’s dancing, hiking, yoga, or just going for a walk to clear your head and you’ll be sure to make time for exercise, rather than excuses.14. Should I take supplements with phentermine?Many doctors now prescribe vitamin B12 and 5-HTP alongside phentermine to help boost the effects and also to help with some side effects, such as insomnia and fatigue. However, here are phentermine.com, we recommend specific supplements which have been designed especially for those taking phentermine. The weight loss multivitamins Phen Vites, are the only multivitamins especially designed for weight loss, and which contains both 5-HTP and B12 to boost the effectiveness of phentermine while also helping to reduce side effects. Phen Vites also include all the essential nutrients your body needs for maximum weight loss potential and optimum health and wellbeing. Phen Drink, specifically designed to stop the dry mouth side effect of phentermine, is another recommended supplement as it also boosts metabolism and helps make water more interesting with its great fruity taste but is totally free of calories, carbs and sugar. We also recommend the weight loss supplement Phen Caps, which are an alternative to phentermine and work excellently alone, but can also be combined with phentermine to boost your results, especially if you think your phentermine isn’t working as well as you had hoped.We hope that we’ve answered all your phentermine questions, but please get in touch with us if you have any more questions by commenting below!
