Getting Off Klonopin For A Drug Test

Taking Klonopin for longer than a few weeks can cause the body to develop a tolerance to the drug and physical dependence.

Klonopin dependence can make it difficult to stop taking it long enough to get a negative drug test result, due to cravings and other uncomfortable withdrawal symptoms.

If you’ve been using Klonopin for more than a few weeks, do not try to stop taking it all at once. To get off Klonopin, you’ll need to taper your dosage with guidance from a doctor.

Overcoming Klonopin abuse may require inpatient or outpatient drug treatment.
