I take a 10mg tablet of hydrocodone for occasional severe back pain due to disc deterioration in my lower back - not every day but a least 3-4 times per week. I do have a legal prescription for this medication. My life insurance company is doing a routine exam including a urine test as I have applied for additional insurance. I don't want them too think I'm some addict or something, so I'd rather them not find it in my urine. How long should I withdraw from taking any medication prior to the exam. Thanks!
