As IP-based video systems continue to gain widespread popularity in the video surveillance market, one of the benefits is the ability to capture high-resolution images through megapixel video. Also emerging is use of the HDTV standards that are prevalent in the consumer video market. The images produced by this new generation of cameras are often collectively referred to as high-definition (HD) or as megapixel images.
That said, Neurontin has an elimination half-life of 5-7 hours, if you have healthy kidneys. That means that half of the drug will be gone from your system in 7 hours, 75% gone in 14 hours, 87.5% gone in 21 hours, etc. As far as I know, commercial drug tests do not routinely screen for Neurontin and I don't believe there is any cross-reactivity with controlled substances.
With an elimination half-life of 10 to 19 hours, Phenergan will be mostly out of your system in two to four days (at least for most practical purposes). However, this should not be interpreted to mean that a drug test will not pick up Phenergan after two to four days.
