Not things you want to have in your system at the same time however a minimal dose of DXM (you determine what that means) probably won't kill you once propylhexedrine has been wearing off but definitely do not dose them together and honestly if you can help it not on the same day. I mean not within 12 hours at least to sound safest. 24 hours of each other would be even safer yadda yadda.Please someone
I will be taking a low dose instead of a moderate dose then. You sir sekio are incredibly knowledgeable aren't you now?It's not very safe, DXM is a pretty strong SNRI even at low doses and taking it with/after propylhexidrine (norepinephrine releasing agent, probably serotonin releaser too) can lead to hypertension, anxiety and panic, and in severe cases serotonin syndrome. At the very least I would expect its effects to be potentiated, especially the stimulating part of DXM.
