Can you take domperidone and tromadol together?

Hi I've just been prescribed Tramadol (Tramset, which is a combination of 37,5mg Tramadol and 325mg Acetaminophen) for muscle pain, and Domperidone (10mg original) taken at the same time to prevent nausea and vomiting from Tramadol. (by a doctor in Japan)

The first time i took Tramadol on an empty stomach, and after having dinner, i got a terrible stomach ache, so i took one 10mg Domperidone as suggested.

My stomach ache and nausea got a lot better, but i must tell you this combinations makes you very sleepy :) I think after a couple of days we will get used to it.

To conclude, from my experience it is safe to take them together (although I'm still on low dose).

I hope you find my info useful :)
