Can Concerta cause breathalyzer to give false readings?

Concerta, a medication used to treat ADHD that contains methylphenidate, is not known to cause false readings on a breathalyzer test for alcohol. Breathalyzers measure blood alcohol content by detecting ethanol, and Concerta does not metabolize into ethanol or interfere with the device's function. However, individual responses to medications can vary, and it’s always important to consult a healthcare professional regarding any concerns about medications and their effects.
