I have taking approximately 35 10-650 or 10-750 Lorcet tablets for the relief of pain due to an injury. I am about to take a urinalysis and I do not want this medication to be in my system even though I have the prescription bottle. I would like to have a clean urine test. Could you inform me on the length of time(such as 3,4,5 days?) that this medication stays in the system and give me some tips on how to rid my body of this medication as soon as possible such as drinking cranberry juice, taking what herbs to cleanse system, etc. Your advice would be greatly appreciated. Again I have the proof that this medication was prescribed to me, but I would rather have a clean urine test for my new job. Thank you again.
