Precautions While Using clorazepate
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. Blood tests may be needed to check for any unwanted effects.
Clorazepate may cause some people, especially older persons, to become drowsy, dizzy, lightheaded, clumsy or unsteady, or less alert than they are normally. Also, clorazepate may cause double vision or other vision problems. Make sure you know how you react to clorazepate 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.
Clorazepate 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 hay fever, allergies or colds, sedatives, tranquilizers, or sleeping medicine, prescription pain medicine or narcotics, medicine for seizures or barbiturates, muscle relaxants, benzodiazepines, or anesthetics (numbing medicines), including some dental anesthetics. This effect may last for a few days after you stop using clorazepate. Check with your medical doctor or dentist before taking any of the above while you are using clorazepate.
Do not stop taking clorazepate 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, nausea or vomiting, stomach or muscle cramps, tremors, or unusual behavior.
Clorazepate may be habit-forming. If you feel that the medicine is not working as well, do not use more than your prescribed dose. Call your doctor for instructions.
If you or your child develop any unusual or strange thoughts and behavior while taking clorazepate, be sure to discuss it with your doctor. Clorazepate may cause confusion, worsening of depression, hallucinations (seeing, hearing, or feeling things that are not there), suicidal thoughts, and unusual excitement, nervousness, or irritability.
It is important to tell your doctor if you are pregnant or planning to become pregnant before using clorazepate.
Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
