Your doctor will check and make sure that other drugs your child is taking are compatible with Clonazepam. This is also important if you are giving your child herbal or complementary medicines. The doctor can check to make sure they are compatible.

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