Pharmaceutical "Specialists"

One of the challenges of living here is that if you need medicine, you kind of have to roll the dice.  Generally the pills we get are labeled in Russian and are not FDA approved.  Also, because most anything is over-the-counter here (and no, I don't mean in a black market sense), you can end up with some serious medication for relatively minor issues.

One of the pills that we have for pain relief is called Pentalgin.  We usually try to research the meds before we use them so I Googled it tonight.  The top hit was a random forum site which seemed promising until I got the following comment:

Ok I just finished some research and found this.

MAIN COMBINATION Metamizole PRODUCTS AVAILABLE IN RUSSIA: BRAND NAMES
AND INGREDIENTS
PENTALGIN (Metamizole sodium 300mg, Paracetamol 300mg, Caffeine
50mg, Codeine phosphate 8mg, Phenobarbitone 10mg)

So these pills have 8mg Codeine, not bad because I have like atleast 50 of them lol. However, what about the other idgrediants? Can I do a CWE? 

Are any of the other ingrediants recreational?

Anyways I dont wanna kill myself, so somebody knowledge please help me.

THANKS!

That's right, in the 3rd to last line he asks if any of the ingredients are "recreational," meaning high-inducing.  My suspicions were confirmed 2 comments later with this one (my family-friendly editing):

codeine with the phenbarb its almsot as good as hydro (-:
a little puff puff and you're set! just be carefull with the APAP(paracetamol), over 2g and your liver is on its way to the moon.

speaking about barns, I popped the last seconal pill i had...%@#$...i want to get some more for my veins...with H

I suspect that I am not getting what would generally be considered a professional opinion.
