FDA Approved Appetite Suppressants

Based on statistics from the Centers for Disease Control and Prevention, close to 40 percent of adults in the US are obese. Weight-loss diets are often difficult to follow for an extended period, as people stay hungry while following them. Some people resort to prescription medicines to help them suppress their appetite, but this should only be done under medical supervision.

Who Should Use FDA Approved Prescription Appetite Suppressants?

It is well known that excess weight is detrimental to one's health and the risk for various chronic conditions, such as diabetes and heart disease, is increased. Although different strategies could help with weight loss, diet combined with exercise is the logical place to start.

If you have however eaten right and worked out for six months and still have no success, you may consider prescription medications, at the discretion of your doctor. The majority of these medications require that you follow a reduced-calorie diet and exercise plan. These medications are normally only prescribed for those who have a BMI of 31 or greater and are therefore regarded as obese. Prescription Appetite Suppressants approved by the FDA may also be appropriate for people classified as overweight (body mass index between 27 and 30) and have health problems such as heart disease.

Appetite suppressants are also known as anorexiants. They work by affecting norepinephrine and serotonin, two brain chemicals. The drugs work by keeping these satiety hormones circulating in the brain. This causes a feeling of fullness, resulting in people eating less.

Some weight loss medication contain stimulant drugs that the Drug Enforcement Agency (DEA) has classified as controlled substances. The FDA approved the first two appetite suppressant drugs in over a decade five years ago. These are Lorcaserin (Belviq) and Phetermine (Qsymia). Since then, other weight loss drugs have been approved, including Belviq XR, Liraglutide (Saxenda) and Bupropion (Contrave).

Prescription Appetite Suppressants Approved by the FDA


In an article published in the Journal of Menopausal Medicine, it was reported that phentermine is one of the FDA approved appetite suppressants often prescribed. As it can be addictive, it is only used short-term - up to six weeks. As is the case with many prescription medications, phentermine has potential side effects, which include constipation, a dry mouth, vomiting, or diarrhea. Heart palpitations, high blood pressure, insomnia, chest pain, leg and ankle swelling, shortness of breath and dizziness are some of the more serious side effects.

In a small study published in Obesity in 2016, it was found that Phentermine could really help those struggling with hunger. The results showed that Phentermine was especially effective in obese people who struggled with their diets because of hunger.


Phendimetrazine is another appetite suppressants approved by the FDA, which works the same as phentermine. It should not be used for more than 12 weeks. Its side effects include nausea, dizziness, diarrhea and constipation. People using it are advised to contact their doctor if they experience nervousness, mood changes, shortness of breath, headaches, chest pain, shakiness, changes in heartbeat, or problems when urinating.

This drug should be used with care. One case was reported where a 54-year-old woman using the drug experienced cardiac ischemia. With this condition, the heart receives too little blood and oxygen, and this could lead to heart muscle tissue dying.


Diethylpropion is also used to control appetite to help with weight loss. The drug is most effective when used in combination with a low-calorie diet. Just like the other appetite suppressants, diethylpropion could cause anxiety-related and gastrointestinal side effects. A doctor should be consulted when symptoms such as itching, skin rash, sore throat, breathing difficulty, blurred vision, chest pain, or fainting are experienced.


The next drug on the list of FDA approved appetite suppressants is bupropion, which is often used to treat multiple psychiatric disorders ranging from seasonal affective disorder to bipolar disorder. Bupropion is also used to assist people to stop smoking. As with all the other drugs mentioned, there is a long list of potential side effects.


Lorcaserin (Belviq) influences the chemical signals in the brain that regulate appetite. Lorcaserin will help you feel full with smaller meals and it is used to treat obesity that may be related to high cholesterol, diabetes, or high blood pressure. Lorcaserin will not treat any of the underlying health conditions. Side effects of this drug includes dizziness, headache, dry mouth, feeling tired, nausea, cough, back pain, constipation and low blood sugar.


Liraglutide (Saxenda) is comparable to a hormone that occurs in the body naturally. It helps control insulin levels, blood sugar and digestion. This injectable prescription medicine may help some overweight or obese adults who suffer from weight related medical problems lose weight and keep it off. It is used in combination with a diet and exercise program. Side effects include nausea, low blood sugar, stomach pain, vomiting, upset stomach, dizziness, headache, diarrhea, tiredness, or constipation.

FDA approved appetite suppressant drugs should only be used by obese people, or people who are overweight or obese and have a medical condition such as high blood pressure or type-2 diabetes. These drugs will not let you lose weight by themselves, but will add a boost to your weight loss diet and exercise program.
