Question

effects when combined? maximum dosage before becoming dangerous? any help will do please.

Answer 1

... your question kind of trailed...

My fiance is on that, he takes it for nausea, in pill form, put he has also had to intraveneously &amp; as a supository.

I&#039;m not sure the max dose, however www.drugs.com should be able to help you out.

Don&#039;t take to much, I know it&#039;s a pretty strong drug.

Answer 2

Either drug (in excess) can cause breathing to stop.  Together, they are a trainwreck,as they potentiate each other.

The amount varies with the individual, but it is suicidal to take either and/or both unless truly necessary for an illness, and then, never in excess.
