A law enforcement investigation determined that the boys also repackaged DXM powder into gelatin capsules purchased at a health food store in order to sell it to others in their high school. At least three nonfatal overdoses resulted from the repackaged DXM, two of which required ER treatment. Older adults may develop DXM addiction due to chronic pain management and the use of multiple medications. As highlighted by the National Institute on Drug Abuse (NIDA), this population is at risk of polypharmacy, where multiple prescriptions can lead to unintentional misuse of DXM. Treatment for dextromethorphan (DXM) addiction involves a combination of behavioral therapies, support groups, and emerging therapies. However, at higher doses, DXM acts as a dissociative anesthetic, similar to ketamine and phencyclidine (PCP).
What Are The Uses Of Dextromethorphan?
It is best known by its trade name, Robitussin, but is commonly found in other cough medicines such as Nyquil, Benylin DM, Coricidin Cough and Cold, and many more. Among other mechanisms of action, DXM and its major metabolite dextrorphan produce its dissociative effects by antagonizing the glutamatergic NMDA receptor. Below is a list of medications, supplements, and foods that can interact with dextromethorphan.
What Happens If I Miss A Dose Of Dextromethorphan?
In higher doses, the effects of DXM become more psychedelic in nature. The effects of high-dose DXM feel a lot like ketamine or other dissociatives. They disconnect the mind from the body which can be both freeing and terrifying at the same time. At the recommended dose, DXM has little, if any psychoactive side effects. In higher doses, DXM can induce states of inebriation similar to alcohol, dissociative states similar to ketamine, or full-blown psychotic episodes like PCP. Long-term misuse of dextromethorphan may lead to psychological dependence.

How Does DXM Addiction Develop?
While all of these over-the-counter medications contain DXM, certain varieties of cold medications are specifically targeted for misuse and abuse. Laboratory tests involve analyzing biological samples to diagnose conditions or measure substance levels in the body. Laboratory tests may be ordered to detect the presence of DXM or other substances in the body.
Brand Names Of Combination Products

One example is Auvelity, which contains dextromethorphan and bupropion. Also tell them about any herbs, vitamins, and supplements you use.

Other Types Of Dissociatives

In response to the rising non-medical use, the DEA convened two advisory committee meetings in the early 1990s, but came to no consensus on what actions to take. In 2010, an FDA panel voted against making DXM a scheduled substance, believing that the public health and economic benefits outweighed the abuse potential of the drug. If you’re interested in taking Delsym instead of dextromethorphan, talk with your doctor or pharmacist. To learn more about how generics compare with brand-name drugs, see this article.

This data specifically reported on calls to poison control centers, which are generally only called in the case of overdose. Trends in over-the-counter substance misuse are often less well-studied than prescription or illicit drug use. However, some data can shed light on the prevalence of DXM abuse. When people misuse DXM in order to get high, they take massive doses well above the recommended daily limit.
