Prescription Weight Loss Pills: Pros & Cons

If you are thinking about talking to your doctor about prescription weight loss pills, you really need to consider the pros and the cons in order to make an informed decision.   There are really only a few prescription diet pills available, but there is a lot to think about and contemplate.

Prescription Weight Loss Pills

Some of the prescription diet pills available are:

  • Orlistat
  • Phentermine
  • Meridia 

These are either classified as appetite suppressants, which mean they trick your brain into believing you are not hungry, or fat burners or blockers, which means they stop fat from absorbing in your body. 


The biggest positive when considering prescription diet pills is the fact that they are Food and Drug Administration (FDA) approved.  In order to be given as a prescription, they have to be researched with clinical studies and be approved.  Therefore, you will know what you are getting.  With over-the-counter products, you cannot be sure what the product actually contains, and since no studies have been done, you cannot predict their outcome.

Another pro to prescription weight loss pills is that since it is prescribed by your doctor, you are working with someone who is monitoring the effects to your body and system.  This means that if the prescription is not right for you, or is not working correctly, you will have the assurance that any ill effects will be caught before any major problems develop. 


The biggest con to prescription weight loss pills is that the long term effects are really not known.  Even though these pills are FDA approved and there have been some studies done, the drugs have not been used long enough to determine if adverse results will occur over time. 

Another con is that these prescriptions can be highly addictive.  They are related to amphetamines and are only intended for very short term use.  You need to make sure that your doctor is aware of your complete medical history, and knows about any addictions that may be a part of your family history. 

Prescription weight loss pills are only for those that are considered obese, and for whom other weight loss methods have not worked.  These are not for anyone just wanting to lose a few pounds.

Lastly, there is still the possibility of side effects with prescription pills.  Some side effects that can occur are:

  • high blood pressure
  • dry mouth
  • constipation 
  • insomnia

The fact is that, even with a diet pill to take, you will still have to work on making lifestyle changes.  Lowering your daily caloric intake is important in losing weight and maintaining the loss.  Incorporating an exercise routine into your life is just as important, even if that means walking for 30 minutes, three times a week.
