The half life of Klonopin (clonazepam) is
35 hours. What this means
in 35 hours after taking a dose, half of the drug is still circulating
in your system. In another 35 hours, half of that which was left at
the first 35 hours, is circulating. And so on and so on, until it is
gone, providing you are not taking anymore. If you are taking your
daily dosages, then you maintain a steady therapeutic dose; the
optimal dosage needed to alleviate disorder symptoms.
Valium is one of the most slowly eliminated benzodiazepines. It has a half-life of up to 200 hours, which means that the blood level for each dose falls by only one half in about 8.3 days. One of the only other benzodiazepine with similar half life is Librax.
Librax is a combination of two separate drugs. One of the drugs (chlordiazepoxide) is a benzodiazepine, a family of drugs which are most often prescribed for anxiety and tension. The other drug (clidinium) is an anti-spasmodic, used to relax the muscles in the gut wall.
Just FYI.
