You may have noticed the acronym “DM” on your cough medicine’s label or noticed it mentioned in the pharmacy. But what is DM, and what does it do?

Understanding Potential Risks of DM in Cough Medicine

While DM is generally safe when taken as directed, there are potential risks associated with the use of this medication. One of the most significant risks is an overdose, which can cause symptoms such as confusion, dizziness, and even seizures. Misuse of DM-containing cough medicine with other substances like alcohol or other medications can also be dangerous and potentially life-threatening.

Some people may also be at a higher risk of complications from DM-containing cough medicine. For example, individuals with liver disease, respiratory conditions, or a history of drug or alcohol addiction should be cautious when taking cough medicine with DM.
