Does Clonidine Show Up on a Drug Test?
Evidence-based answer reviewed against SAMHSA cutoffs and FDA assay documentation · Updated August 2026
Quick answer: No — not on any standard panel. Clonidine is absent from routine 5-, 10-, and 12-panel employment drug tests. Never screened.
Which panels screen for it
| Panel | Clonidine status |
|---|---|
| 5-Panel | ❌ Not included |
| 10-Panel | ❌ Not included |
| 12-Panel | ❌ Not included |
| DOT 5-panel (safety-sensitive) | ❌ Not included |
The details that matter
Clonidine (used for blood pressure, ADHD adjunct and opioid withdrawal symptoms) never appears on drug panels and produces no false positives in assay validations. Continue prescribed use normally.
If it IS detected, how long does it last?
| Test type | Typical Clonidine detection window |
|---|---|
| Urine | any: not tested / no interference |
| Saliva (Mouth Swab) | any: n/a |
| Hair Follicles | n/a |
| Blood | any: n/a |

How accurate are drug tests?
Lab-based immunoassay screens agree with confirmation testing ~97% of the time; confirmed GC–MS results are considered definitive. Home kits trade legal defensibility for convenience.
Do prescriptions count against me?
No — verified prescriptions report as negative through the Medical Review Officer. Declare medications at collection and answer the follow-up call.
