While eating a well-balanced, reduced-calorie diet and exercising regularly are the cornerstones of weight loss, certain drugs can serve as powerful adjuncts. One such drug is phentermine. One of the most popular weight loss drugs in the world.
It has been proven effective for short-term weight loss when used alongside a reduced-calorie diet and exercise.
What Is Phentermine?
Phentermine (Adipex-P, Lomaira) is an amphetamine-like prescription medication used to suppress appetite. It can help weight loss by decreasing your hunger or making you feel full longer. Phentermine is also available in combination with topiramate for weight loss (Qsymia).
Like other prescription weight-loss drugs, phentermine is intended to be used as part of an overall weight-loss plan. It is indicated for people who are obese, and who have failed to lose enough weight with diet and exercise alone — not for people who want to lose just a few pounds.
Uses
It is used by certain overweight people, such as those who are obese or have weight-related medical problems. Losing weight and keeping it off can lessen the many health risks that come with obesity, including heart disease, diabetes, high blood pressure, and a shorter life.It is not known how this medication helps people to lose weight. It may work by decreasing your appetite, increasing the amount of energy used by your body, or by affecting certain parts of the brain. This medication is an appetite suppressant and belongs to a class of drugs called sympathomimetic amines.
How Does It Work?
Phentermine belongs to a class of drugs called “anorectics,” also known as appetite suppressants.
Taking phentermine helps suppress your appetite, thereby limiting how many calories you eat. Over time, this can lead to weight loss.
While the exact mechanisms behind the appetite-reducing effects of phentermine remain unclear, the drug is thought to act by increasing neurotransmitter levels in your brain (6Trusted Source, 7Trusted Source).
Phentermine While Pregnant:
If you took phentermine before pregnancy, it should have no effect on your ability to carry a healthy baby to term. All traces of phentermine should pass through your body. Even if you took your last dose a week before conception, it shouldn’t have any effect on your pregnancy.
Dosage and Forms
Dosages for phentermine vary depending on its form and concentration. The available doses of phentermine were 15, 30, and 37.5 mg.
You should avoid taking the last dose too late in the day to prevent insomnia or difficulty falling or staying asleep.

Side Effects
Phentermine alone is designed for short-term use only, as there are no long-term studies on its safety.
While serious adverse effects are rare, studies report several side effects of the phentermine and topiramate combination.
The most commonly reported side effects include:
Dry mouth
Sleeping problems
Dizziness
Heart palpitations
Flushing of the skin
Fatigue
Constipation
Irritability
You shouldn’t take phentermine if you have heart disease, hyperthyroidism, glaucoma, or if you’re pregnant or nursing.
Phentermine should also not be prescribed in combination with monoamine oxidase inhibitors (MAOIs), a class of medications used to treat depression.
Your doctor will determine whether phentermine is appropriate and safe for you.
