Can someone who is taking Western medicine get Wigobi and Maunzaro together?

Hello. I am currently taking diet medication, but I feel that the effects are a bit slow with medication alone.

Can I get Wigobi or Maunzaro while taking diet medicine?

Of course, doing them at the same time wouldn't be allowed, right?

If I want to get Wigobi Maunzaro, do I need to stop taking Western medicine and wait a while before getting it?
