Clonazepam is a benzodiazepine drug sold under the brand name Klonopin. Clonazepam for anxiety acts as a tranquilizer that produces sedative effects: it functions by calming down one’s mind and nerves.

This drug is a controlled substance, so a prescription is required to purchase it. It is available in tablets and syrup but it might not always be offered in every strength or form that the brand-name equivalent has. Also, as a generic medication, it typically costs less Klonopin.

However, these are not all the key aspects you should know about Clonazepam. Read out to learn what Klonopin is used for, its dosage, and its side effects.

Clonazepam Uses

Clonazepam is usually used to treat seizures and epileptic seizures or keep them under control. In such a case, it is referred to as an anticonvulsant or antiepileptic drug. Additionally, this medication is prescribed for the following conditions:

Is Klonopin Good for Anxiety?

Klonopin is FDA-approved [4*] for the treatment of panic attacks and seizure disorders. Still, it can also be prescribed to patients with different forms of anxiety as it can ease its symptoms. Even while the full effects of Klonopin are noticed within an hour or so after taking it, in some cases, they may not be felt for up to four hours. But in comparison to some other benzodiazepines, this drug usually has a longer half-life, so its effects can last for up to 12 hours.

What Happens When You Take Clonazepam?

The exact Clonazepam’s mechanism of action is unclear. Still, experts have several opinions based on the effects of this drug and the causes of the conditions it treats.

Anxiety, mood problems, seizure disorders, and pain have all been connected to low GABA (gamma-aminobutyric acid) levels. This is because GABA is a neurotransmitter that blocks impulses between nerve cells in the brain.

As an anticonvulsant and a drug with sedative effects, Clonazepam operates on nerve cells to help calm abnormal electrical activity in the brain. So, according to experts, clonazepam keeps GABA at a high level in the central nervous system to impart its anticonvulsant, muscle relaxant, and anxiolytic actions. It does so by strengthening the affinity of the GABA-benzodiazepine receptor complex for GABA by strong binding.

Clonazepam Dosage for Anxiety

Klonopin dosage for anxiety will vary depending on the patient’s condition and symptoms. Only use Klonopin for anxiety as recommended by your doctor and also observe the label’s instructions.

Note: The following details are only the typical dosages of this medication. Unless your doctor instructs you to, do not alter your dose if it differs from the one disclosed below.


Starts from 0.25 mg twice daily. If necessary, the doctor might change the dose, not making it greater than 4 mg per day, though.

Alternative Meds for Anxiety

Even though Clonazepam has a positive average rating and reviews from patients and doctors, your doctor may substitute it with other anxiety medications. It can be done if this drug isn’t helping you or isn’t a good fit for you for some other reasons.

The two replacements for Clonazepam are alprazolam (Xanax [5*] ) and lorazepam (Ativan [6*] ). Xanax can be used to treat anxiety attacks or panic disorder, but it is more addictive, and withdrawal symptoms from it can be very uncomfortable. Ativan is used to treat anxiety too and also belongs to benzodiazepines. Both alone and in combination with other drugs, Ativan is a good option.
