What is a major side effect associated with Rythmol (propafenone)?

Rythmol, or propafenone, is an antiarrhythmic medication primarily used to treat certain types of irregular heartbeats. Among its potential side effects, visual disturbances are notably significant. Patients taking propafenone may experience adverse effects such as blurred vision and other changes in visual perception, stemming from the medication's impact on the central nervous system and the visual pathways.

Visual disturbances are particularly important to monitor, as they can affect a patient's daily activities and overall quality of life. Understanding this side effect is crucial for healthcare providers in guiding patients about the potential risks versus the benefits of their treatment plan.

In contrast, while bradycardia (a slower than normal heart rate), seizures, and hyperglycemia (high blood sugar) can be associated with various medications or medical conditions, they are not as characteristic of propafenone's profile or as commonly reported by patients on Rythmol. This highlights why visual disturbances are a crucial side effect to be aware of when assessing the medication’s impact.
