How long will it take for me to feel the effects of clonazepam?1hr?i know it's slower than xanax (alprazolam)

Within an hour: Clonazepam is a longer acting drug than Xanax (alprazolam) and its' effects are less immediately evident. However, depending on your size, diet, metaboisim, etc. it usually takes less than an hour to begin working. The efffects will be more subtle, in that the purpose is to maintain balance over time rather than stopping a panic attack.
