It is important before you leave home that you make sure all of your medical prescriptions are up to date, including things like reading glasses and any medication you may need. It may be cheaper for you to do this before you leave your home country rather than in Sri Lanka, but remember to travel with a doctor’s prescription listing your name, to show the medicines are for your personal use.
