Looking For A Set With OTC/RX Medications, Recommended Dosages, And Safe Dosing Intervals

I’m brainstorming a project and while I’m sure a set like this exists in the world, I imagine the risk of misuse and liability makes it difficult for someone without a doctorate to get their hands on. Looking to you folks for even a mock dataset/csv that would have something like

Ibuprofen, 200-400mg, 4-6 hours

Eventually, I would like to work towards a more complete dataset that factors body mass where applicable but something to this effect with even just OTC recommendations would be a huge boon

TIA!
