Misc Expired Donnatal Elixer

ok. I found an ancient bottle of Donnatal Elixer. It's completely full and god damn do I hope it's still good. It expired in 1991. It's been stored properly and doesn't even look like it has been open at all. Any thoughts?

Donnatal ingredients:
Phenobarbital, USP ................................... 16.2 mg
Hyoscyamine Sulfate, USP ........................ 0.1037 mg
Atropine Sulfate, USP ............................... 0.0194 mg
Scopolamine Hydrobromide, USP ............. 0.0065 mg

Sweet Jesus I hope this is still good.

It should be fine, but phenobarbital is probably less fun than dropping sandbags on your head over and over. The atropine alkaloids won't help either.

Pheno was good for potentiating bupe in minuscule doses (under 20mg, more often around 5, and every other day), but that's it. Can't imagine taking a full dose. Unlike valium which also has a very long Half-Life, pheno is no fun.

Phenobarbital is not a fun drug to consume in recreational qualities unless you are going through benzo WD. Quit trying to be a drugstore cowboy and put the medicine back where you stole it.
