Clonazepam

About

  • Clonazepam is an anticonvulsant used to control seizures (fits).
  • It can be useful in several types of seizures such as epileptic spasms and myoclonic seizures.
  • It is usually used with other anticonvulsants in epilepsies that are difficult to control.
  • It can also be used for the emergency treatment of seizures or clusters of seizures.

Clonazepam must be prescribed by a doctor. You should never give your child anyone else's medications.

Interactions

  • Depression of breathing can occur, especially if used with other medicines that suppress the brain. This is particularly important in children with swallowing and breathing problems.

Need-to-know

  • Depression of breathing can occur, especially if used with other medicines that suppress the brain.
  • This medication should not be stopped suddenly as seizures may increase.
  • There is also a withdrawal syndrome in chronic use.
  • Clonazepam is prescribed in either a liquid or tablet form.
  • The liquid (oral) preparation requires great care in its usage to avoid overdose:
    • The oral liquid is measured in DROPS only (not in millilitres - do not draw up into a syringe).
    • The drops should not be administered directly into the mouth.
    • Drops should be counted onto a spoon and preferably given directly, or can be mixed with a liquid (e.g. water or juice) if desired. 
    • Ensure you discuss with your doctor exactly how many drops should be used for your child.

Monitoring and Levels

Pregnancy and contraception

  • If a pregnancy is planned, a discussion with your neurologist is recommended.
