In general, these tend to be dose related with the higher doses resulting in higher reports of adverse effects. Because it is a benzodiazepine, abrupt discontinuation should be avoided. This drug needs to be tapered slowly, otherwise withdrawal symptoms can occur.
Withdrawal symptoms may include convulsions, hallucinations, behavioral disorder, tremor and anxiety. There is the chance of physical and psychological dependence on this drug.
Similar to other seizure drugs, there is also the risk of suicidal thought or behaviors in patients who take this drug. The most common side effects that led to treatment stoppage in the control trials included lethargy, somnolence, ataxia, aggression, fatigue and insomnia. Other common side effects include gastrointestinal issues, decreased appetite and issues related to depression or psychiatric problems such as aggression or insomnia. Most people who take clobazam have no side effects or mild side effects that go away in a short time with no lasting harm.
Serious reactions, such as a drug-related skin rash, have been extremely rare. Call your doctor right away if you notice a rash soon after you start taking clobazam. Like many other seizure medicines, clobazam makes some people feel sleepy or uncoordinated. If you've just started taking clobazam or have just had your dosage increased, be careful when doing things that could be dangerous until you know how it will affect you.
Be especially cautious if you tend to be sensitive to medications or if you are taking another medicine that could make you sleepy. One of the great dangers in using medications like clobazam is the tendency to increase the dose as tolerance develops. To a certain extent, this is necessary, but adverse effects may be increased more than seizure control.
If the dosage is increased gradually over a long period, subtle changes in personality such as irritability, depression, or decreased motivation or problems such as impaired memory may go unnoticed or be considered natural for that person.
High doses sometimes are prescribed for children and adults, especially those with developmental disabilities. Problems with thinking and behavior may be the result.
If the dose has been increased gradually over many months or years, it can be hard to separate the effects of the clobazam or other benzodiazepines from the effects of other medications, seizures, and other neurological and psychological disorders.
An important concern when people with epilepsy take clobazam or other benzodiazepines is the risk that seizures will become more frequent or more severe if the medicine is reduced or stopped.
Withdrawal syndrome usually begins as soon as the patient stops taking the medicine and lasts for 8 to 10 days. The longer the person has been taking clobazam and the higher the dose, the greater the tolerance and therefore the higher the risk of worsening seizure control. Even small, gradual dose reductions can temporarily increase seizure activity, but the long-term decrease in effects like drowsiness and depression often makes the change worthwhile.
On July 10, , an advisory panel was convened by the Food and Drug Administration FDA to review data that the FDA had previously collected from drug studies showing an association between many of the antiepileptic drugs AEDs and suicidal ideation and behavior, which together are called suicidality.
We again urge patients and families to contact their doctor before stopping an epilepsy medication because this may possibly lead to seizures and worsening of mood.
