Clonazepam is used alone or together with other medicines to treat certain seizure (convulsive) disorders (e.g., Lennox-Gastaut syndrome, akinetic or myoclonic seizures). It is also used to treat panic disorder in some patients. Clonazepam is a benzodiazepine. Benzodiazepines belong to the group of medicines called central nervous system (CNS) depressants, which are medicines that slow down the nervous system.
clonazepam is available only with your doctor's prescription.
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 clonazepam, the following should be considered:
Tell your doctor if you have ever had any unusual or allergic reaction to clonazepam 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.
|All Trimesters||D||Studies in pregnant women have demonstrated a risk to the fetus. However, the benefits of therapy in a life threatening situation or a serious disease, may outweigh the potential risk.|
There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding.
Using clonazepam with any of the following medicines is usually not recommended, but may be required in some cases. If both medicines are prescribed together, your doctor may change the dose or how often you use one or both of the medicines.
Using clonazepam with any of the following medicines may cause an increased risk of certain side effects, but using both drugs may be the best treatment for you. If both medicines are prescribed together, your doctor may change the dose or how often you use one or both of the medicines.
Certain medicines should not be used at or around the time of eating food or eating certain types of food since interactions may occur. Using alcohol or tobacco with certain medicines may also cause interactions to occur. Discuss with your healthcare professional the use of your medicine with food, alcohol, or tobacco.
The presence of other medical problems may affect the use of clonazepam. Make sure you tell your doctor if you have any other medical problems, especially:
Take clonazepam only as directed by your doctor. Do not take more of it, do not take it more often, and do not take it for a longer time than your doctor ordered.
If you or your child are using the orally disintegrating tablet (wafer), make sure your hands are dry before you handle the tablet. Do not open the blister pack that contains the tablet until you are ready to take it. Remove the tablet from the blister pack by peeling back the foil. Do not push the tablet through the foil. Do not break or split the tablet. Place the tablet in your mouth. It should melt quickly. After the tablet has melted, you may take a sip of water.
The dose of clonazepam will be different for different patients. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of clonazepam. If your dose is different, do not change it unless your doctor tells you to do so.
The amount of medicine that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are using the medicine.
If you miss a dose of clonazepam, take it as soon as possible. However, if it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not double doses.
Store the medicine in a closed container at room temperature, away from heat, moisture, and direct light. Keep from freezing.
Keep out of the reach of children.
Do not keep outdated medicine or medicine no longer needed.
Ask your healthcare professional how you should dispose of any medicine you do not use.
It is very important that your doctor check the progress of you or your child at regular visits to see if the medicine is working properly and to allow for changes in the dose. Blood tests may be needed to check for any unwanted effects.
Using clonazepam while you are pregnant can harm your unborn baby. Use an effective form of birth control to keep from getting pregnant. If you think you have become pregnant while using the medicine, tell your doctor right away. Your doctor may want you to join a pregnancy registry for patients taking a seizure medicine.
clonazepam may cause drowsiness, trouble with thinking, trouble with controlling movements, or trouble with seeing clearly. Make sure you know how you react to clonazepam before you drive, use machines, or do anything else that could be dangerous if you are not alert or able to think or see well.
clonazepam may cause some people to be agitated, irritable, or display other abnormal behaviors. It may also cause some people to have suicidal thoughts and tendencies or to become more depressed. If you, your child, or your caregiver notice any of these side effects, tell your doctor or your child's doctor right away.
If you or your child have been taking clonazepam in large doses or for a long time, do not stop taking it without checking first with your doctor. Your doctor may want you to gradually reduce the amount you are using before stopping it completely. This may help prevent a worsening of your condition and reduce the possibility of withdrawal symptoms, such as convulsions (seizures), hallucinations, stomach or muscle cramps, tremors, or unusual behavior.
clonazepam will add to the effects of alcohol and other central nervous system (CNS) depressants (medicines that make you drowsy or less alert). Some examples of CNS depressants are antihistamines or medicine for allergies or colds; sedatives, tranquilizers, or sleeping medicine; prescription pain medicine or narcotics; barbiturates (used for seizures); muscle relaxants; or anesthetics (numbing medicines), including some dental anesthetics. Check with your doctor before taking any of the above while you are using clonazepam.
Along with its needed effects, a medicine may cause some unwanted effects. Although not all of these side effects may occur, if they do occur they may need medical attention.
