Although the drug or substance interaction can vary, certain common interactions are to be noted.

Here's a detailed look at what to avoid when taking clonazepam.

Opioid Pain Relievers

Opioids top the list. Opioids such as tramadol, oxycodone, and morphine, are usually prescribed for moderate to severe pain. When combined with clonazepam, these medications can cause excessive drowsiness and life-threatening respiratory issues. The FDA has issued a warning against this combination. If both medicines are necessary, you must follow the instructions of a healthcare professional. They will prescribe a safe dosage, and guide you on safe usage intervals. Seek immediate medical help if you experience excessive drowsiness or breathing problems.


Everyone knows what antihistamines are, they treat seasonal allergies. But they can increase drowsiness when taken with clonazepam. Older antihistamines like diphenhydramine (Benadryl) and hydroxyzine (Vistaril) pose a higher risk. If you want to take them necessarily because of your allergic condition, switching to non-drowsy antihistamines such as fexofenadine (Allegra) is recommended. Additionally, nasal steroid sprays like fluticasone propionate (Flonase) are safer alternatives.

Sleep Aids

Combining clonazepam with sleep aids can increase drowsiness. If you are using prescription sleep aids like ramelteon (Rozerem), zolpidem (Ambien), and suvorexant (Belsomra), they should be used under medical supervision. Over-the-counter sleep aids, including diphenhydramine (ZzzQuil), doxylamine (Unisom), and melatonin, also elevate the risk of drowsiness. If sleep aids are required, consult a healthcare professional who will advise on safe usage and monitor for serious side effects.

Other Seizure Medications

If you are someone who is managing seizure disorders with multiple medications, clonazepam interactions can worsen your condition. Medications like phenytoin (Dilantin) and carbamazepine (Tegretol) may intensify drowsiness or alter clonazepam’s effectiveness. Some, like carbamazepine and lamotrigine (Lamictal), might reduce clonazepam levels, necessitating dosage adjustments. Your doctor may also check phenytoin levels more frequently to manage potential changes in drug efficacy.

Other Medications That Cause Drowsiness

Various medications can enhance clonazepam’s sedative effects. You should be extra careful with muscle relaxers like cyclobenzaprine, MAOIs like rasagiline (Azilect), tricyclic antidepressants like amitriptyline, and beta-blockers like metoprolol (Lopressor). Consult your pharmacist or a healthcare professional about your medications to monitor potential drowsiness and other side effects.


Of course, alcohol significantly impacts your health if you mix it with any medications. If you take alcohol with clonazepam, it affects the brain. The combination will amplify sedative effects and increase the risk of severe respiratory issues. You should be very careful if you are consuming clonazepam medicine then you must take one drop of alcohol. If you consume alcohol regularly, discuss your habits with your doctor to ensure safe medication use and consider support for reducing alcohol intake.


Though research on cannabis and clonazepam interactions is limited, both substances can cause drowsiness and impaired coordination. Combining them could intensify these side effects. Inform your doctor about cannabis use to manage any potential risks effectively.

Herbal Remedies

Herbal remedies like valerian or passionflower used for anxiety and insomnia should be avoided while taking clonazepam. These herbal remedies have the potential to increase clonazepam’s sedative effects. Limited testing on other herbal supplements means their safety with clonazepam is unknown. Before adding any other supplements to your diet always consult your doctor.
