If possible, carry enough medication to cover your needs for the length of time you plan on traveling. Most states allow for the transfer of prescriptions from a pharmacy in another state and written by a prescriber in another state. Certain types of controlled substances may only be transferred once during the life of the prescription. Health Maintenance Organizations often don't allow for payment to pharmacies outside their geographical area. If you will be spending an extended amount of time in one place, your regular pharmacist may, for a nominal postage fee, mail your refilled prescription to you.
Smaller bottles are usually available.
Ask your pharmacist to provide you with properly labeled bottles for ease of packing. The following information should be applied when traveling outside the United States. Anticipate your needs and have ample supply. Never store prescriptions in checked luggage. Always place in your carry-on bag.
