Some medications are prescribed with this taken into account actually.

For example if a medication has sedating effects (such as some antidepressants) it may be advised to be taken before bed so this side effect is turned into something generally beneficial (more sleep) and less prevalent during waking hours).

Statins (cholesterol lowering medications) are usually prescribed at night time as this is when your cholesterol catabolism is most active.

Pain relief is often varied around sleep schedules

Insulin is scheduled around meals and sleep

Etc etc.

Things like insulin may be driven by life events and as needed. But I'm talking about regularly scheduled medication.

Antidepressants may be advisable to take before bed as a rule, but it's an excellent example of drugs that are supposed to be taken at the same time every day. Irregularly moving around the hour you take the antidepressant makes them less likely to work.

That's why irregular sleep schedules aren't a good reason to move medication.
