Addnok 0.2 mg contains buprenorphine, which may cause physical dependence when used for a long time. Stopping it suddenly can trigger withdrawal symptoms such as anxiety, sweating, nausea, tremors, and general discomfort. For this reason, it should not be discontinued on your own. A qualified doctor will design a safe tapering plan to gradually reduce the dose and minimise withdrawal effects. Always consult your prescribing physician or an addiction specialist before making any changes to your medication.
