If you believe that someone close to you has been abusing Oxycontin there are several outward signs to look for. These include drowsiness, slowed breathing, slurred speech, constricted pupils, inexplicable nausea and vomiting, and profuse sweating. There are also a fair amount of behavioral signs to be aware of. For example, if someone is “doctor shopping” – making appointments with a variety of doctors in hopes of receiving as many prescriptions as possible – this is a very big indication of addiction. Attempting to forge prescriptions is also common among Oxycontin addicts, as is stealing medication or purchasing the medication from a drug dealer.
