Use of Off-Label Drugs and Nutrition Supplements among Patients with Amyotrophic Lateral Sclerosis in Norway.

ABSTRACT

Materials and Methods: A cross-sectional questionnaire study was performed, where 41 ALS patients reported their use of off-label treatments, as well as self-perceived HRQOL using the RAND-12 questionnaire. Results: A majority of respondents used riluzole. Of the 41 respondents, 18 (43.9%) reported use of off-label medications and 18 (43.9%) used nutritional supplements. Low-dose naltrexone was the most commonly used off-label medication, whereas vitamins accounted for most of the nutritional supplements. The respondents' RAND-12 component scores were significantly lower than those of the general population. Low-dose naltrexone and vitamin B were associated with a better physical component score. Conclusions: Most of the respondents in our study adhere to the recommended treatment protocols, as less than half of them reported using off-label medications or nutritional supplements against ALS. Positive correlations between physical HRQOL and use of low-dose naltrexone or vitamin B were demonstrated. These results warrant further investigations.
