How Long After Vyvanse Can I Take Klonopin?

VyvanseADHD – Attention-Deficit/Hyperactivity Disorder

It takes eight hours for Vyvanse to be eliminated from the blood and 2 to 3 days to be eliminated from urine. Vyvanse does not provide you instant relief as it may take at least one hour to kick in. Make sure to start with a standard dosage of 30mg and you may feel a little difficult to get used to the medication for 2 to 3 days.

The main advantage of Vyvanse is that it’s enough if you take it only once a day. Another important thing is that you have to take Vyvanse in the morning itself because its effect may last up to 12 to 14 hours. So, if you eat later your sleep will be disrupted and also you have to take it when you have some important meetings on a specific day or if you are having a large amount of work and so on.

You will get the energy, the focus, and all the good stuff through the Vyvanse as it is a good stimulant for our Central Nervous System. Klonopin is also known as Clonazepam. It is mainly used to treat panic attacks and different types of seizures.

Seizures occur when there is abnormal excitation of neurons and therefore Klonopin is used to enhance the inhibitory neurotransmitters that are, it slows down the electrical activity of the brain. Klonopin is also used to treat insomnia, generalized anxiety, restless leg syndrome, and so on. There can also be some side effects like dizziness, weakness, sedation, and so on.

Why Should You Wait For At Least 2 To 3 Days To Take Klonopin After Taking Vyvanse?

Before taking any drugs everyone should know about the drug’s interactions, precautions, and side effects. For example, taking an antidepressant with Vyvanse can create serious heart problems and so on. Having Vyvanse without any problems like ADHD is not good as the dopamine levels in the brain increase and there will be a disturbance in brain communication.

This may lead to euphoria. Vyvanse is one of the best medications for ADHD as it needs to be taken only one time a day and its effects last for 12 to 14 hours. Whatever stimulant it may be it should not be taken without any medical reasons. Citrus fruits and supplements which contain vitamin C should not be taken while under Vyvanse medication. Because this increases acidity in urine and is less effective.

Limiting caffeine products and avoiding consumption of alcohol is very important while taking Vyvanse, Klonopin, and also any other stimulants. You should follow whatever your doctor advised you. The standard dosage of Klonopin for epilepsy is 0.5 mg and should be taken three times a day. The quantity can be increased gradually and can be taken up to 20mg a day. For panic attacks, the initial dosage is 0.25mg and should be taken two times a day.

Taking Klonopin produces inhibitory effects throughout our body like drowsiness, decreased anxiety, relaxation of muscles, sedation, and much more. When the side effects are increased the dosage should be reduced accordingly. Therefore, it is clear that Vyvanse is used as Central Nervous System stimulant whereas Klonopin is used a Central Nervous System depressant. These two drugs have completely opposite purposes.


Before undergoing any medications one must know about the drug interactions of that particular medication. Just googling about some medicines and taking them without a doctor’s prescription is a bad habit and it may even lead to serious problems. This is a common problem among everyone these days.

One must first consult a doctor if they feel there is some problem in their body and then he/she should properly follow the instructions, precautions, do’s and don’ts, and everything said by his/her medical advisor. Avoiding alcohol and smoking while taking any medications will help you heal faster and avoid others risks and seriousness in your body.
