How long to wait until eating the eggs?

[StarLover21]

We finished giving my hen her cold medication- Tylan 50 cattle medicine 9 days ago. She layed her first egg after the treatment 8 days ago. How much longer should we wait until eating her eggs? Another four days? I've heard two weeks...is that right?

I would especially if someone (some human) is allergic to whatever the active antibiotic is in that medication.
