Klonopin's Dosage: What to Know
This drug has
Risk of misuse and addiction. Taking benzodiazepines, such as Klonopin, can increase the risk of misusing or becoming addicted to the medication. (Misuse means taking a drug differently from how your doctor prescribed it. This is sometimes called abuse.) Misusing benzodiazepines can result in serious complications, including overdose and, in some cases, death.
Risk of dependence and withdrawal. Taking benzodiazepines, including Klonopin, for an extended period may lead to dependence. (With dependence, your body needs the drug in order to function like usual.) Physical dependence can cause withdrawal symptoms if you stop taking the medication abruptly. (Withdrawal symptoms are side effects that can happen after you stop taking a drug that your body is dependent on.) Withdrawal symptoms can be severe and life threatening in some cases. To minimize this risk, your doctor will gradually decrease your dosage if you’ve been taking high Klonopin dosages or taking the medication long term.
Risk of serious injury or death when taken with opioids. Taking benzodiazepines, including Klonopin, with opioids can lead to serious side effects. These may include slowed breathing, excessive sleepiness, coma, and in some cases, death. Due to this risk, doctors may not prescribe Klonopin with opioids unless other treatments do not work. If your doctor prescribes Klonopin with an opioid, they’ll monitor you closely for signs of serious side effects.

Below are some common questions related to Klonopin’s dosage.
Is Klonopin used for sleep? If so, what’s the dosage for sleep?

What’s the recommended dosage of Klonopin for panic attacks or anxiety?
For panic disorder, the starting dosage is typically 0.25 milligrams (mg) twice per day. Your doctor may gradually increase your dosage until you have the desired effect from the drug.
Panic disorder is a type of anxiety disorder. However, there’s no specific Klonopin dosage for anxiety. That said, your doctor may prescribe this dosage if panic attacks are a symptom of your anxiety disorder.

Your doctor will consider several factors when prescribing the dosage for Klonopin. These factors include:
- your age

- the condition you’re taking Klonopin to treat
- the severity of your condition
Your prescribed dosage may also vary based on other medical conditions you have.
Recommended adjustments in dosage
If you are age 65 years or older, you may be started on a lower dosage of Klonopin to treat your condition. Older people may have an increased risk of side effects. These may include sleepiness, lack of coordination, or dizziness. Your doctor will likely monitor you more closely for side effects.
If you have kidney or liver problems, be sure you let your doctor know before starting Klonopin. Kidney or liver problems may affect how well your body breaks down the drug and increase your risk for side effects. Your doctor will likely prescribe a lower dose of Klonopin if you have kidney or liver problems.

If it’s difficult for you to swallow tablets, see this article for information on taking this form of medication. Talk with your doctor or pharmacist and ask if they have other suggestions to help you take the medication.
If you find it challenging to read the label on your prescription, tell your doctor or pharmacist. Certain pharmacies provide medication labels with large print or braille. They may also offer labels containing a scannable code that your smartphone can convert from text to speech. If your pharmacy doesn’t provide these choices, your doctor or pharmacist may be able to recommend a pharmacy that does.
If it’s difficult for you to open medication bottles, ask your pharmacist if they can dispense Klonopin in an easy-open container. They also may recommend ways to help make it easier to open the bottles.
If you miss a dose of Klonopin, take it as soon as you remember. If it’s almost time for your next dose, skip the missed dose. Then, take your next dose at the regular time. Do not take two Klonopin doses together to make up a missed dose. Doing this can increase your risk of side effects.
