5. Trial of dietary modifications (2–4 wk) |

6. Trial of a previously preferred laxative agent (2–4 wk) |
|
7. Trial of a laxative agent supported by evidence from RCTs involving older people (2–4 wk) |

↵* Steps 1 through 3 should be undertaken concurrently.
↵† Step 4 should be undertaken concurrently with each of steps 5 through 8.
