After a little googling i have come to te conclusion that these are not recreational. Even if high doses cause delerium, it would also probably include a host of undesired side effects like these:
hot, dry skin and extreme thirst;
severe stomach pain or constipation;
pain or burning when you urinate; or
urinating less than usual or not at all.
Less serious side effects may include:
dry mouth;
dry eyes, blurred vision;
mild constipation;
diarrhea;
nausea, mild stomach pain or upset;
dizziness, drowsiness, weakness;
headache;
sleep problems; or
runny nose.
Got those from Drugs.com
So, no dont take those. Just sell them to someone at your local middle school as "oxy"
