Do you have medications you regularly take? What do you do with these when you travel?
The Centers for Disease Control and Prevention has some recommendations for travelers and their medications.
First, check to see if your medications are available at your planned destination. This goes for non-prescription as well as prescription meds. You may need to get an extra prescription filled before you leave, especially if you're planning on being away from home for an extended period of time.
Next, keep a sheet of contact information for your doctor and pharmacy, along with your list of medications. This should be kept in the folder or place where you keep your important documents.
Also, get an official prescription from your physician. If you are flying, keep these with your carry-on luggage, not in your checked luggage.
If you're flying, be sure to show medicines to a TSA agent before going through security check.
If travel plans involve time zone changes, consult a doctor or pharmacist to create a specific travel schedule for this circumstance. As much as possible, stay on track when taking medicines.
