Who can use phentermine?
For short-term weight management in adults over 16 years old, phentermine is a medication that the FDA has approved. The Food and Drug Administration (FDA) has authorized the use of additional weight-loss drugs in adults and children over the age of 12 including orlistat (Xenical) and liraglutide (Saxenda). When diet and lifestyle changes are insufficient to help a person lose weight, doctors will prescribe phentermine. The objective is to lessen the chance that being overweight or obese will cause health issues.
Your doctor will assess your BMI to decide whether phentermine is the best option for you. According to recommended guidelines, people with a BMI of 30 or more or a BMI of 27 or higher with a weight-related disease such as high blood pressure or diabetes may be administered phentermine.
It is important to remember that not everyone with a BMI above 30 should use drugs to manage their weight. A stringent low-calorie diet and lifestyle regimen that incorporates constant, high-intensity to frequent physical exercise might help some people reach their ideal weight.
What phentermine drawbacks are there?
Phentermine's poor reputation stems mostly from two factors:
- Chemically, phentermine is comparable to amphetamines.
Phentermine is listed as a Schedule IV prohibited drug by the U.S. Food and Drug Administration (FDA). This is so because phentermine shares a molecular structure with amphetamines, which are stimulant pharmaceuticals that may be abused and addictive. Phentermine is not an amphetamine, though. Studies have demonstrated that people taking phentermine for weight reduction do not experience misuse or addiction. It has not been discovered that using this medicine to treat an addiction causes phentermine drug cravings. Additionally, even after prolonged usage, there are no withdrawal symptoms if phentermine use is quickly terminated.
- Phen-fen included phentermine.
In the past, phentermine has been combined with different weight-loss medications. One such mixture, phen-fen, a weight-loss medication, attained enormous popularity in the 1990s. It was known as phen-fen because it contained phentermine and fenfluramine, also known as dexfenfluramine. When it was discovered that the fenfluramine and dexfenfluramine components of phen-fen were seriously causing heart problems, the FDA removed the medication from the market in 1997. The drug itself, however, was seen as secure.
Is Phentermine safe for all?
Phentermine is not a magic bullet or a substitute for a healthy diet and regular exercise. When your body mass index (BMI) is over 30, or when it is over 27, and you have a serious weight-related medical condition like diabetes or high blood pressure, you should only think about taking phentermine or another weight loss medication.
When used in conjunction with a comprehensive weight-management strategy that incorporates lifestyle changes and is administered under medical supervision, phentermine is safe. It can be extremely dangerous and illegal to obtain phentermine from non-medical sources and use it as a quick fix for weight loss. Remember that you will likely regain all the weight you lost if you don't make the necessary behavioral and lifestyle changes to maintain a healthy weight.
Why Phentermine Is A Schedule IV Controlled Substance?
A controlled substance classified as Schedule IV is thought to have a low risk of abuse and dependence. Schedule IV drugs typically have medical applications and value. Schedule IV drugs, however, are still regarded as having some addictive qualities and can be harmful if used in high doses alone or combined with other drugs.
