I had Botox on the forehead 1 wk ago. My lids look droopy but I'm scared to take iopodine drops. Any suggestions?

I would recommend waiting a bit more time and then re-evaluate any drooping of your upper eyelids after the Botox treatment to your forehead one week ago.  In many cases, there may be some initial droop that improves fairly quickly with more time.  I would wait maybe 3-4 weeks to see if it gets better.  Botox results usually last about 3-4 months but can last longer for some people.  

The muscle that lifts your eyebrows is the same muscle that causes the horizontal lines of the forehead.  When using Botox in the upper forehead those lines relax but so can the eyebrows causing the "droopy" look you described.  Time is your friend and this will resolve.  Sometimes, treating the muscles in the glabella (between the eyebrows) and the crows feet can counteract the affect.  The forehead is one of the trickiest spots to get the dose "just right".  Too much and the brow droops, to little and you don't see the results you want.  Work with your provider to dial in the right dose for you.
