You will likely need some over-the-counter medicine while you travel.
This is a nice kit that includes 6 types of the most commonly used over-the-counter drugs.
What we like best about these, is that you don’t have to buy a big bottle, put a few pills into a plastic pill bag, then try to get the label off the bottle and into the pill bag. (Because you don’t want to have to carry 6 bottles with you!)
And this kit comes with directions for use.
Note: I do not bring the box. You can take the packets out of the box and put them into your First-aid bag.
