PharmChek® Drug Patch Products
PharmChem, Inc is the manufacturer of the PharmChek® Sweat Patch and the PharmChek® Overlay, which combine to form a continual testing device that cannot be easily adulterated, tampered, or substituted. Worn for 10+ days, all evidence of drug use during the wear-period is captured in the cellulose pad and submitted to the laboratory for analysis.
PharmChek® Sweat Patch
The PharmChek® Sweat Patch (or Drug Patch) by PharmChem, Inc. is worn on the skin for up to 10 days and uses sweat as the specimen source. PharmChek® not only acts as a deterrent to continued drug use, but also offers the following advantages:
- Ongoing window of detection
- Outcomes can be used as both reward or sanction
- Lab screen detects parent drug and drug metabolite
- Rapid application & variable removal date
- One patch can replace multiple urine collections
- No undetected substitution, dilution, or adulteration
- Gender neutral as no urine collections
The PharmChek® Overlay
The PharmChek® Overlay is made of the same polyurethane film as the PharmChek® Sweat Patch and can be used to extend the wear time of the PharmChek® Sweat patch.
Who May Need to Wear the PharmChek® Overlay?
Circumstances best suited for Overlay include:
- Individuals who may be exercising heavily.
- Individuals in strenuous work roles.
- Individuals residing in hot or humid climates.
These individuals may produce a large amount of sweat very quickly. Occasionally, the sweat cannot evaporate through the film fast enough, which may cause the adhesive to loosen. The Overlay’s construction allows a larger surface area for excess sweat to be reabsorbed by the body.
