Clonazepam is a benzodiazepine medication used as a supplement to other antiepileptic drugs to treat a variety of seizure types in children. It is taken by mouth, usually two or three times daily. A variety of side effects may occur in children taking clonazepam; these side effects can affect many systems and parts of the body.
Heart and Lung Related Side Effects
Children on clonazepam may experience low blood pressure. A decrease in breathing rate, fewer than normal breaths per minute may also occur.
Central Nervous System Side Effects
One of the most common side effects of this medication is drowsiness. Children taking clonazepam may also feel dizzy, experience headaches or feel confused. Changes in personality, aggressive behavior, depression and decreased concentration have all been noted as potential effects. Finally, clonazepam may lead to the development of suicidal thoughts and behaviors especially in older children.
Neuromuscular Side Effects
Children taking clonazepam may experience strange movements called choreiform movements; these are fast, jerking movements that the child has no control over. They sometimes also experience tremors.
Digestive System Side Effects
A child taking clonazepam may feel nauseous and vomit. Diarrhea or constipation may occur. Dry mouth, also called xerostomia, may be present due to a decrease in the amount of saliva produced by the salivary glands in the mouth. Alternatively, the child may experience hypersalivation, an increase in the amount of saliva produced. Clonazepam can also cause a decreased appetite in children.
Eye-Related Side Effects
Clonazepam can cause blurry vision. Nystagmus, a condition in which the eyes move rapidly from side to side and appear to be shaking, is another side effect experienced by some children taking this drug.
Other Side Effects
Other side effects such as rashes, blood cell abnormalities such as anemia and physical and/or psychological dependence may occur in children taking clonazepam.
