Appetite Suppressants: What You Need to Know

Are you looking for rapid weight loss, long-term, sustainable weight loss, or both? Most likely, you would love to lose weight quickly and keep it off.

At WeightLoss+ in Louisville, Kentucky, we offer you a medically supervised weight loss program that can give you both, if you properly follow it. In addition to nutritional counseling, we can help you lose weight through the managed use of diet medications, including appetite suppressants.

Because some diet medications have been questionable – either because of health risks or lack of consistent performance – you may have some concerns. At our weight loss center, we will only prescribe safe, effective diet medications to meet your weight-loss needs.

Phentermine vs. Fen Phen

Depending on your needs, you may be prescribed a diet medication. One appetite suppressant that our Louisville weight loss doctor may prescribe is Adipex, which is the brand name for Phentermine. If you are panicked because Phentermine was one of the drugs in the controversial diet medication Fen Phen, don't be.

Yes, it is true that Phentermine was one of the two main drugs in Fen Phen. The questionable drug cocktail included Fenfluramine (Fen) and Phentermine (Phen). However, after receiving numerous reports of potentially serious side effects, including increased risk of heart valve disease, the U.S. Food and Drug Administration (FDA) requested the withdrawal of drugs contacting Fenfluramine and Dexfenfluramine (another popular weight loss drug used with Phentermine referred to as Dexfen Phen). The FDA did not and has never requested the withdrawal of Phentermine from the market place.

So, although Fen Phen was an unsafe diet medication, Phentermine is still and has been a safe appetite suppressant for over fifty years. You don't need to worry about any adverse health effects.

FDA-approved Prescription Diet Drugs

You may have heard of various diet medications either through ads, friends talking, or even your own research. However, the two main types of prescription weight-loss drugs are appetite suppressants and lipase inhibitors (fat blockers).

At our Louisville weight loss clinic, we may prescribe an appetite suppressant or fat blocker depending on your needs. The chart below outlines those FDA-approved diet medications.

Benefits of Diet Drugs

As noted above, several diet medications (mostly appetite suppressants) are available to treat obesity and aid in weight loss.

Some of the many benefits to using appetite suppressants include:

  • Average weight loss using appetite suppressants is 5 to 22 pounds, which is higher than the expected weight loss for patients not using diet medications.
  • Losing at least 10 percent of your body weight can reduce your risk for heart attack, stroke, and cancer.
  • After losing weight with the help of appetite suppressants, you will most likely experience an increase in your energy level.

Risks and Dangers of Diet Drugs

As with any medication, you should be aware of the potential risks of diet medications before you start using an appetite suppressant.

Some possible risks of using appetite suppressants include:

  • Diet medications can cause minor side effects including increased heart rate and blood pressure, dry mouth, constipation, insomnia, and headache. These side effects generally subside with continued treatment.
  • There is a chance that you will develop a tolerance to your appetite suppressant and your weight loss will level off after four to six months.
  • You could potentially regain your weight when you stop taking diet medications, if you do not take the other steps necessary to live a healthy life.

If you have any concerns regarding diet medications, speak with our weight loss doctor before you are given a Phentermine prescription. Because of these potential risks, you should not take appetite suppressants (or any prescription medication) without medical supervision.

Tackling the Diet Drug Plateau

Diet medications may have varying effects for different people. Because of this, a diet pill that works well for one of our Louisville patients may not work as well for you. There is also a chance that an appetite suppressant will work well for you for several months, but then you will find your weight loss tapering off and even stopping before you reach your weight loss goal.

This can be a very frustrating experience, but you are not alone in this journey. Because we offer a medically supervised weight loss program, your doctor can monitor your progress and alter your diet medication as needed. Also, by incorporating a healthy diet and exercise routine into your life, you can help yourself through these potential roadblocks to weight loss.
