Which would possibly cause or have the most side effects if taken?
Would the side effects show up after a minimum of 24 hours from actually be taken?
How long can they stay in your system?
Darvocet is not as strong a drug as oxycodone. In fact given its relatively weak performance and the possibility of side effects and potential for addiction made panel to the FDA recently recommended that it be taken off the market - and replaced with other better drugs.
Most of the serious side effects - such as an allergic reaction to the drug - occur soon after a drug is ingested. This is because the longer the drug stays in your system the more it is broken down into innocuous components. Most pain drugs are broken down fairly quickly - after a couple of hours the active components are essentially gone. The metabolites from most narcotic drugs can't be detected in your urine after a couple of days.
