Phentermine 37.5 mg is a prescription medication to be used in a person suffering from overweight. Losing and maintaining weight helps to prevent the numerous health issues linked with obesity, such as heart disease, diabetes, high blood pressure, and a shortened life span. With a doctor-approved exercise, behavior modification, and low-calorie diet plan, one can buy Phentermine online to lose and maintain weight. The FDA has approved it for short-term use of up to 12 weeks because using it for a long can increase the risk of dependence. As a Schedule IV controlled substance, it can only be used under the supervision of a doctor.
Phentermine 37.5 mg works as an appetite depressant. It belongs to a class of drugs called sympathomimetic amines. Drugs of this class work directly on the brain to increase the level of certain neurotransmitters called norepinephrine, serotonin, and dopamine. When the level of these three substances increases, the hunger level decreases. However, you may develop a resistance to phentermine’s appetite-suppressing effects within a few weeks. If this occurs, contact the healthcare provider who prescribed it.
Phentermine remains in your system for roughly four days following administration. Half of the medication leaves your system in around 20 hours. Many factors influence how long it takes for a medicine to exit your system. These include age, diet, renal and liver function, and other factors. After three months of taking this medication, the typical weight loss is 3% of your initial body weight and 5-7% after six months. If you haven’t lost much weight after three months of using it, a doctor may advise you to stop taking it.
