What other drugs will affect clonazepam?

Cold or allergy medicine, narcotic pain medicine, sleeping pills, muscle relaxers, and medicine for depression or anxiety can add to sleepiness caused by clonazepam. Tell your doctor if you regularly use any of these medicines, or any other seizure medications.

Also tell your doctor if you are using any of the following drugs:

• propantheline (Pro-Banthine);
• an antibiotic such as fluconazole (Diflucan), itraconazole (Sporanox), ketoconazole (Nizoral), or voriconazole (Vfend);
• an antidepressant such as amitriptyline (Elavil, Etrafon), doxepin (Sinequan), imipramine (Janimine, Tofranil), nortriptyline (Pamelor), and others;
• a barbiturate such as amobarbital (Amytal), butabarbital (Butisol), mephobarbital (Mebaral), secobarbital (Seconal), or phenobarbital (Luminal, Solfoton);
• an MAO inhibitor such as isocarboxazid (Marplan), phenelzine (Nardil), rasagiline (Azilect), selegiline (Eldepryl, Emsam), or tranylcypromine (Parnate); or
• medicines to treat psychiatric disorders, such as chlorpromazine (Thorazine), haloperidol (Haldol), mesoridazine (Serentil), pimozide (Orap), or thioridazine (Mellaril).

This list is not complete and there may be other drugs that can interact with clonazepam. Tell your doctor about all the prescription and over-the-counter medications you use. This includes vitamins, minerals, herbal products, and drugs prescribed by other doctors. Do not start using a new medication without telling your doctor.
