Generic name: clonazepam [kloe-NAZ-e-pam] Clonazepam has been found to be effective in the acute control of non-convulsive status epilepticus; however, the benefits tended to be transient in many people, and the addition of phenytoin for lasting control was required in these patients. [103], Combined use of clonazepam with certain antidepressants, anticonvulsants (such as phenobarbital, phenytoin, and carbamazepine), sedative antihistamines, opiates, and antipsychotics, nonbenzodiazepines (such as zolpidem), and alcohol may result in enhanced sedative effects. [92], Clonazepam may aggravate hepatic porphyria. The site is secure. This further results in an inhibition of synaptic transmission across the central nervous system.

[77][78] Chronic use of benzodiazepines can lead to the development of tolerance with a decrease of benzodiazepine binding sites. If clonazepam is used during pregnancy or breastfeeding, it is recommended that serum levels of clonazepam are monitored and that signs of central nervous system depression and apnea are also checked for. [9], The elderly are especially susceptible to increased risk of harm from motor impairments and drug accumulation side effects. Clonazepam's mode of action is to decrease abnormal electrical energy in the brain. You should not take clonazepam if you allergic to it or if you have: a history of allergic reaction to any benzodiazepine (including alprazolam, diazepam, lorazepam, Valium, Xanax, Versed, and others).

Some withdrawal symptoms may last up to 12 months or longer after stopping this medicine suddenly. A recurrence of symptoms of the underlying disease should be separated from withdrawal symptoms. These values do not apply to results that are converted to other units of measure. Vomiting and diarrhea can disrupt normal absorption and metabolism of medications and reduce excreted amounts to undetectable levels. Both the parent drug and 7-aminoclonazepam are unstable in biofluids, and therefore specimens should be preserved with sodium fluoride, stored at the lowest possible temperature and analyzed quickly to minimize losses.
