New Diet Drugs Not Being Used

Diet DrugsA joint survey was conducted by the online medical news service MedPage Today, Everyday Health and The Daily Meal to evaluate physicians’ methods of treating obesity. They surveyed almost 1000 providers and found that the newer drugs such as Qsymia (phentermine/topiramate) are only being used by about 6% and Belviq (lorcaserin) in only 3.3%. Several of the survey respondents cited the high cost of the medications as barriers to use. One provider noted that “middle class (patients) and below cannot afford “these medications so he prescribes generic phentermine 37.5 mg one half tablet each morning with generic topiramate 25 mg twice a day with similar effectiveness.

Fat absorption blockers such as orlistat in it’s over the counter form “Alli” or its prescription form xenical were popular with over 20 % of respondents using those products. Generic phentermine was used alone by 16%. Other medications frequently mentioned included metformin the diabetic drug, and victoza another diabetic drug not yet approved for weight loss therapy.

The majority of the respondents prescribe diet and exercise to begin with. Weight Watchers is their favorite commercial diet with over 75% of those surveyed noting that it works steadily and safely. The South Beach Diet was the clear runner up. When the Atkins Diet was mentioned there was concern and controversy.

In our local clinical practice we are asked frequently about medication to lose weight. The survey did not look at the average age of the patients the respondents treated and their associated medical issues. Locally we have many elderly individuals using multiple medications for heart disease, elevated lipids, diabetes, heart rhythm control and other complex problems. It is much more difficult to find any oral medications for weight loss that do not adversely react with their prescribed medicines or that are not contraindicated due to their underlying medical problems.
