A generic form of the prescription Phentermine, Anoxine AM Oral can be used with a physician monitored and approved reduced calorie diet and exercise program, generally adopted for the rest of your life or at least an extended period of time, far past the use of Anoxine AM Oral. You should theoretically take this medication once a day 1 hour before breakfast or 1-2 hours after breakfast depending on what your doctor recommends. You can take it in doses anywhere from 8mg 1-3 times per day. Over the day, you can get anywhere up to 24mg. But this is essentially meant to provide a gentler dose for the same effects, depending on how sensitive your body may be at that time. This dosage is specifically made for more sensitive individuals. Therefore the side effects are less likely to be severe. However, just like its 37.5mg counterpart, it is only meant to be taken for a few weeks. Most copycats however copy the more popular 37.5mg dose.
