Picture
When seeing their physicians, patients may think that it's not important to mention the over-the-counter medications being taken. The truth is quite the opposite:

Your medical history calls for meds, 
Not just the ones prescribed on scripts;
But vitamins and supplements,
And others claimed without such slips.

Well known by doctors old and young
Are interactions these may have.
Some meds will meet with bonhomie
While others fight, requiring salve.

If best results you hope to find,
​Your gentler pills must share the light.
When harmful matchups are foreseen,
The plan must change, avoiding plight.
