Clonazepam
Klonopin / Generic tablets and orally disintegrating tablets
A guide for adults taking clonazepam.
Follow the directions on your prescription and your provider's recommendations.
Formulations: Standard tablets and orally disintegrating tablets are available. Follow the handling instructions for your formulation.
What it is used for
Clonazepam treats panic disorder and certain seizure disorders. Some other anxiety uses are off-label. A seizure-treatment schedule should not be changed to occasional use.
How it works
It enhances GABA activity, reducing excessive nerve firing. Its long duration can provide sustained effects, but sedation and impaired coordination may also carry into the next day.
What to expect over time
Effects can begin after the first dose. The timing and duration depend on the formulation and dose. Sleepiness or impaired coordination may last longer than the relief you notice.
Your provider should review whether ongoing treatment is helping and whether the dose or duration should change. Do not increase the dose when the effect seems weaker.
Taking your medication
- Follow the prescribed schedule and dose.
- For a dissolving tablet, use dry hands and let it dissolve in the mouth as directed.
- If you miss a dose, take it when you remember unless it is almost time for the next dose. Then skip it. Do not double a dose.
- Never stop abruptly after regular treatment, especially if used for seizures.
When to get help
Emergency symptoms. Call 911 for slow or difficult breathing, inability to wake, collapse, or a seizure. Severe confusion or hallucinations after reducing or stopping may be dangerous withdrawal.
Prompt medical advice. Contact your provider promptly for repeated falls, marked memory problems, unusual aggression, or needing more medication to get the same effect.
If you feel unsafe or have thoughts of self-harm, call 911 or go to an emergency department.
Possible side effects
- Sleepiness, slowed reactions, or fatigue
- Dizziness, poor balance, or falls
- Memory problems or difficulty concentrating
Keeping track of treatment
Some side effects resolve with time; others may require a change of medication. Discuss persistent or bothersome side effects with your provider.
Watch for daytime sedation, falls, memory changes, and breathing problems. Older adults and people taking other sedatives may be more sensitive.
Physical dependence can develop with regular use. Sudden stopping or a rapid reduction can cause severe withdrawal, including seizures. Dependence is different from addiction, but misuse and addiction are also possible.
If you take too much
For a suspected overdose, call Poison Control at 1-800-222-1222 immediately, even if you feel well. Call 911 for a seizure, collapse, trouble breathing, or inability to wake.
Before you start
Discuss sleep apnea, lung disease, liver or kidney disease, glaucoma, falls, and any history of substance use problems. Tell your provider about all opioids and other sedatives.
Discuss pregnancy, pregnancy plans, and breastfeeding with your provider. Treatment decisions should consider both the medication and the condition being treated.
Medicines and interactions
Review all your medications with your provider, including over-the-counter medicines and supplements. Have new medications checked before taking them.
Combining a benzodiazepine with an opioid can cause profound sedation, slowed breathing, coma, or death. Use such combinations only under a specifically reviewed treatment plan.
Avoid alcohol. Sleeping pills, sedating antihistamines, muscle relaxants, and other sedatives can increase impairment and breathing risks.
Medicines that affect CYP3A metabolism may change levels. Review grapefruit and all additional sedatives with your provider.
Everyday tips
Do not drive until you know how the medication affects you. Avoid driving whenever sleepy or impaired.
Keep medication locked away. Never share it, even with someone who has similar symptoms.
Arrange refills or taper instructions before you run out.
Your questions answered
Can I stop after taking it regularly?
Consult with your provider before reducing or stopping. A gradual, individualized taper helps limit withdrawal. Do not borrow medication or change the schedule to manage withdrawal yourself.
What if I feel unusually agitated?
Some people develop disinhibition, irritability, or agitation. Contact your provider rather than taking an extra dose.
Storage and safety
Keep medication in its labeled container, away from excess heat and moisture and out of reach of children and pets. Do not share it. Ask a pharmacy about disposal of unused medication.
