Medicine in Colombia (Bogotá)

Hi,
I have a regular prescription but I would be able to bring amount for only a few months

My question are:
1. Do you have any experience with shipping medicine from your country to Colombia? (just a small amount for personal use of course)

2. What about over the counter drugs - is it common?

3. Is there a Colombian website where I can search from a list if they selling my medicine in Colombia?

Thanks in advance
