Which of the following is a common adverse effect of Procainamide?

Dizziness is a well-documented adverse effect of Procainamide, which is an antiarrhythmic medication used to treat certain types of irregular heartbeats. This effect can occur due to the drug's action on the cardiovascular system, as it can lead to reduced blood pressure or alterations in cardiac output, potentially causing a sense of lightheadedness or instability.

In addition, Procainamide can affect the central nervous system, which may also contribute to feelings of dizziness. This side effect is particularly important for healthcare providers to monitor, as it can impact a patient's ability to perform daily activities safely.

Other side effects of Procainamide include various gastrointestinal disturbances and effects on other body systems, which may not include dizziness. Understanding these common adverse effects is crucial for patient education and management when prescribing this medication.
