Uses For Klonopin Wafers
Clonazepam is used alone or together with other medicines to treat certain seizure disorders (eg, Lennox-Gastaut syndrome, akinetic, myoclonic, and absence seizures). It is also used to treat panic disorder. Clonazepam is a benzodiazepine that works in the brain to prevent seizures. Benzodiazepines are central nervous system (CNS) depressants, which are medicines that slow down the nervous system.
This medicine is available only with your doctor's prescription.
Before Using Klonopin Wafers
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:
Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Appropriate studies performed to date have not demonstrated pediatric-specific problems that would limit the usefulness of clonazepam in children with seizure disorders. However, safety and efficacy in children with panic disorder have not been established.
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of clonazepam in the elderly. However, elderly patients are more likely to have confusion and severe drowsiness, or age-related heart, liver, or kidney problems, which may require caution and an adjustment in the dose for patients receiving clonazepam.
