Clinical Description

Definition of Underdosing

Underdosing occurs when a patient receives less than the prescribed or recommended amount of a medication. This can happen for various reasons, including patient non-compliance, medication errors, or issues related to drug availability. In the context of T44.906, the underdosing specifically pertains to drugs that impact the autonomic nervous system (ANS), which controls involuntary bodily functions such as heart rate, digestion, and respiratory rate.

Autonomic Nervous System Overview

The autonomic nervous system is divided into two main branches:
- Sympathetic Nervous System: Responsible for the body's 'fight or flight' response, increasing heart rate and blood flow to muscles.
- Parasympathetic Nervous System: Promotes the 'rest and digest' functions, slowing the heart rate and enhancing digestion.

Drugs affecting the ANS can include a variety of medications, such as those used to manage conditions like hypertension, heart failure, and certain psychiatric disorders. Underdosing these medications can lead to inadequate control of symptoms and may exacerbate underlying health issues.

Clinical Implications

Symptoms of Underdosing

Patients experiencing underdosing may present with a range of symptoms depending on the specific drugs involved and the conditions being treated. Common symptoms may include:
- Increased heart rate or palpitations
