Adverse events<br />

No significant differences were detected between<br />

DEX <strong>and</strong> MPH treatments in <strong>the</strong> incidence <strong>of</strong><br />

headache, stomach ache, loss <strong>of</strong> appetite or<br />

insomnia. Data on weight were not reported.<br />

Summary<br />

One study evaluated medium-dose MPH<br />

compared with low-dose MPH. 50 This study<br />

reported significant effects in favour <strong>of</strong> MPH when<br />

hyperactivity was assessed by teachers, but not<br />

when assessed by parents. They reported no<br />

significant differences between treatments in <strong>the</strong><br />

incidence <strong>of</strong> headache, stomach ache, loss <strong>of</strong><br />

appetite or insomnia. Owing to <strong>the</strong> poor reporting<br />

<strong>of</strong> some methodological criteria, <strong>the</strong> results from<br />

this study should be interpreted with caution.<br />

MPH medium dose (15–30 mg/day) versus DEX<br />

medium dose (10–20 mg/day)<br />

One study evaluated medium-dose<br />

(15–30 mg/kg/day) immediate release IR-MPH<br />

compared with medium-dose (10–20 mg/day)<br />

DEX (Table 55; with additional information in<br />

Appendix 12). In this crossover study by Arnold<br />

<strong>and</strong> colleagues, 37 hyperactivity was assessed using<br />

four scales. The authors reported no differences<br />

between medium doses <strong>of</strong> MPH <strong>and</strong> DEX<br />

(Table 56). This study did not report on CGI.<br />

It generally scored well in <strong>the</strong> quality assessment.<br />

Adverse events<br />

Adverse event data were not reported adequately<br />

to be included in <strong>the</strong> analysis.<br />

Summary<br />

The one study that evaluated medium-dose MPH<br />

compared with medium-dose DEX reported no<br />

difference in hyperactivity scores between <strong>the</strong><br />

treatment groups. 37 This study did not examine<br />

CGI or adequately report on adverse events data.<br />

It rated well in <strong>the</strong> quality assessment, hence<br />

<strong>the</strong> results for hyperactivity are likely to be<br />

reliable.<br />
