The use of expectorants is not without considerations. Patients must be aware of potential side effects, which can include gastrointestinal discomfort, dizziness, and allergic reactions. Furthermore, it is essential to use expectorants under the guidance of a healthcare professional, as they can interact with other medications or exacerbate certain medical conditions. For instance, individuals with a history of asthma must be monitored closely when using any respiratory medication, including expectorants, due to their potential to induce bronchospasm if not personally tailored.
