As manufacturer of Clonazepam we hereby state the following facts about the drug:


Therapeutic uses and effectiveness:

  • Clonazepam is off-white to light yellow crystalline powder with a faint odor. It is anticonvulsant and GABA modulator. It is a synthetic benzodiazepine derivative indicated for myotonic or atonic seizures, absence seizures, and photosensitive epilepsy. It is used especially in absence seizures (petit mal) including atypical absence; primary or secondarily generalized tonic-clonic (grand mal), tonic or clonic seizures; partial (focal) seizures with elementary or complex symptomatology; various forms of myoclonic seizures, myoclonus, and associated abnormal movements. But, it is rarely effective in generalized tonic-clonic or partial seizures.
  • Clonazepam is indicated as monotherapy or as an adjunct in the treatment of Lennox-Gastaut syndrome (petit mal variant). Additionally, clonazepam is also indicated for the treatment of the panic disorder, with or without agoraphobia. Panic disorder is characterized by the occurrence of unexpected panic attacks and associated concern about having additional attacks, worry about the implications or consequences of the attacks, and/or a significant change in behavior related to the attacks.  It can be used in infants and children for most types of epilepsy
  • Animal data and electroencephalographic investigations in man have shown that clonazepam rapidly suppresses many types of paroxysmal activity including the spike and wave discharge in absence seizures (petit mal), slow spike-wave, generalized spike-wave, spikes with temporal or other locations, as well as irregular spikes and waves. Moreover, the agent can also decrease the frequency, amplitude, duration, and spread of discharge in minor motor seizures.

Other related information:

  • Clonazepam is used predominantly as an anticonvulsant as adjunctive therapy in the management of epilepsy. Therapy with clonazepam is not associated with serum aminotransferase elevations, and clinically apparent liver injury from clonazepam, if it occurs at all, must be exceedingly rare
  • Clonazepam is a DEA Schedule IV controlled substance. Substances in the DEA Schedule IV have a low potential for abuse relative to substances in Schedule III
  • Benzodiazepines like clonazepam commonly cause drowsiness, ataxia, dysarthria, and nystagmus. Overdose with clonazepam is generally not life-threatening if the drug is taken alone, but may lead to areflexia, apnea, hypotension, cardiorespiratory depression, and coma

Increased salivation, hypersecretion in upper respiratory passages, chest congestion, rhinorrhea, and shortness of breath may occur in patients receiving clonazepam. In one study, increased salivation, mucous obstruction of the nasopharynx and bronchi, and difficulty in swallowing occurred in infants receiving the drug. The investigator reported that these effects occurred most frequently when clonazepam was used in conjunction with phenobarbital
