Abstract

Background

Polypharmacy can appropriately treat multiple chronic conditions, but it can also increase potential harm. Polypharmacy information for primary headaches is minimal, despite drugs being the main tools to manage headaches.

Objective

The aim was to evaluate the prevalence, characteristics and risk factors of polypharmacy in patients with primary headaches and examine whether these variables differ between episodic and chronic headache patients.

Methods

We analysed polypharmacy (simultaneous use of five or more medications), medication type, comorbidity, and risk factors in 300 patients (mean age 42.81 ± 13.21 years) with primary headaches, divided into episodic and chronic, afferent to a headache centre.

Results

Patients took an average of 4.37 medications. Polypharmacy was common in 40.7% of patients, and among chronic patients, it reached 58.8%. Most patients used medications (mainly nonsteroidal anti-inflammatory drugs; 73.5%) to treat acute headaches, and 30.4% of episodic and 64.7% of chronic sufferers underwent prophylactic treatment (P < 0.0001), mostly using antidepressants (77.3%). Up to 76.7% of the cohort was taking other medications, primarily for acid-related disorders (21.7%). Comorbidities were present in 59.7% of the cohort. Variables significantly associated with polypharmacy were comorbidities, prophylactic treatment, and triptans (P < 0.001).

Conclusions

Patients with primary headaches, mainly young adults, are exposed to high polypharmacy, comparable to that of the elderly. Because increased numbers of drugs increase the risk of adverse reactions, the many medications concomitantly taken by primary headache sufferers should be frequently reviewed.
