Table of Contents

Clonazepam is a medicine that is used to manage seizures. It's also used to help people who are having panic attacks. Clonazepam belongs to the benzodiazepine family of drugs. It works by reducing abnormal brain electrical activity. you can purchase Klonopin online from a certified online pharmacy, but it is recommended to get a doctor's prescription first.

When using Klonopin, some people find it more difficult to exercise. As Klonopin users become more inactive, their activity levels drop, and they may engage in mindless eating or even binges. Depression and anxiety have been connected to weight increase, leading to changes in eating and activity levels. Clonazepam has been linked to increased depression, and overeating can be used as a short-term coping mechanism for uncomfortable feelings.

Connection Between Clonazepam (Klonopin) and Weight Gain?

According to studies on the drug's effects, there is a link between clonazepam and weight gain. However, it is exceedingly rare. Weight loss has been documented in more clinical trials than weight gain, which happens in less than 1% of patients, implying a minor link between the two. Despite the statistically unlikely link between clonazepam and weight gain in patients, it is a possible adverse effect of the medication that can usually be addressed with lifestyle adjustments.

Patients who are experiencing clonazepam-related weight gain may improve their condition by changing their food and lifestyle. These patients' doctors frequently encourage them to eat lean meats, fish, poultry, and plenty of fruits and vegetables. Exercising for half an hour on most days of the week is another smart approach to avoiding weight gain, minimizing saturated and trans fat intake. People who try to lose weight should avoid alcohol because most alcoholic drinks are high in calories and frequently take in excess. (Hooshang, H. and Masood, H., 1999)


Clonazepam can be taken as a pill. The tablets should be swallowed whole after being taken with water.

For Seizure Disorders:


The initial dose should not exceed 1.5 mg/day for adults, divided into three doses. Dosage can be raised in 0.5 to 1 mg increments every 3 days until seizures are under control. Depending on the patient's response, the maintenance dosage must be customized for each patient. The maximum daily dose that should be taken is 20 mg.

Paediatric Patients:

The initial dose for children and infants (to 10 years of age or 30 kg of body weight) should be 0.01 to 0.03 mg/kg/day, divided into two or three doses. Unless seizures are controlled, or adverse effects prevent further increase, dosage should be raised no more than 0.25 to 0.5 mg every third day till a regular maintenance dosage of 0.1 to 0.2 mg/kg of weight is attained. If the doses are not evenly distributed, the greatest dose should be given first.

Geriatric Patients:

Patients older than 65 should be started on low dosages of Klonopin and properly monitored.

For Panic Disorder:


The starting dose is 0.25 mg twice a day for individuals. After 3 days, most patients may receive a 1 mg/day increase in their target dose. The suggested amount of 1 mg/day is based on the findings of a fixed-dose trial. However, some people may benefit from doses up to 4 mg/day, and in those cases, the dosage can be raised in increments of 0.125 to 0.25 mg twice every 3 days.

Paediatric Patients:

Klonopin has no clinical trial experience in panic disorder individuals under 18.

Geriatric Patients:

Patients over the age of 65 should be started on low dosages of Klonopin and properly monitored.
