FDA Approved Weight Loss Drugs

  • Saxenda 
    First Injectable medication approved by FDA for appetite supression and weight control. Saxenda is a hormone (GLP-1) produced by our intestines after we eat. It binds to receptors in the brain to tell us we are full. However, enzymes in our body destroy the hormone within a few minutes. With technology advancement, scientists are able to make the hormone more resistant to degradation. The effects of Saxenda can last a whole day. One needs to self-inject daily with a very small needle.                                                                          
  • Qsymia
    Qsymia contains a combination of phentermine (3.75, 7.5 and 15mg) and topiramate (23, 46 and 92mg). Both are in very low doasge. The idea of using this combination is to have Synergistic effect (2 plus 2 greater than 4)on hunger and appetite suppression. Using low dosage of each medication will avoid getting side effects of either of the medication. Common side effects are dry mouth and numbness and tingling in fingers.                                                                         
  • Belviq
    A new medication that binds to a very specific serotonin receptors in the brain that supress our appetite. While some serotonin reuptake inhibitors e.g. Prozac, Paxil, Zolfot and Celexa regulate our mood, Belviq only works to decrease our hunger. It could be used in conjunction with people who are taking Serotonin Reuptake Inhibitors. Common side effects are headache and feeling tired.                                                                                                                              
  • Contrave (generic: Bupropion and Naltrexone)
    Again, Contrave contains two medications that has been around for many years. Naltrexone is commonly used for people who has  issues with taking alcohol and opiates while Bupropion has been approved as an Anti-depressant and Smoking Cessation. The combination can reduce appetite. Common side effects are nausea and dizziness.
  • Adipex (generic: Phentermine)
    Used for reducing weight in those that are overweight when combined with exercise, diet, and behavior modification. Phentermine is an appetite suppressant that works by helping to release specific chemicals in the brain to control appetite.
  • Tenuate (generic: Diethylpropion Hydrochloride)
    An appetite suppressant. It works by acting on the appetite center of the brain to cause a temporary reduction in hunger or craving of food.
