Can I take phentermine (37.5mg) once the Obalon balloon(s) are inserted?

Hi and thank you for your question! You can certainly take phentermine, or other weight loss medications, with an intragastric balloon.There is no contraindication for taking Phentermine after the placement of Obalon.  But as usual for taking this medication, make sure your physician has thoroughly examined you prior.

Yes!
You can certainly take phentermine, or other weight loss medications, with an intragastric balloon. Hopefully the balloon(s) would allow you to achieve your weight loss goals. However, we sometimes find that patients remain hungry even with an Orbera or Obalon balloon. It's not common, but it can happen. In this situation, I definitely recommend considering a medication. There are several good options. Phentermine is one. Saxenda, which helps to further slow stomach emptying, may also be a good option when the balloon(s) are removed, as it may help to keep weight off by working through a similar mechanism as intragastric balloons.
Ultimately, the goal is to help you reach your weight loss goals. I suggest using all approaches available.
