Y50.2: Methylxanthines, not elsewhere classified

Methylxanthines are a class of medications typically used to treat respiratory disorders like asthma and chronic obstructive pulmonary disease (COPD). However, improper usage or overdose can lead to harmful side effects, alluded to by the ICD-10 code Y50.2. These effects can include nausea, vomiting, diarrhea, insomnia, and restlessness. In more severe cases, you may experience palpitations, arrhythmias, or even seizures. Generally, these symptoms occur due to methylxanthines' stimulating effects on the cardiovascular and central nervous systems. The severity of the symptoms can depend on the amount consumed and the individual's tolerance level. Accidental intake or intentional overdose can cause these adverse effects, hence, it's essential to follow the prescribed dosage. This condition isn't transmitted from person to person as it's tied directly to drug usage.
