First, if you are regularly taking prescription medications, talk to your doctor to determine whether you will need to adjust your medication schedule or dosage. Also, you may want to find out how your medication should be stored to best maintain its effectiveness.
Be certain that your doctor gives you a prescription for a sufficient quantity to last the entire trip, plus a few extra days to cover unexpected delays or schedule changes. Be sure to carry a copy of your prescription with you, in case your medication gets lost.
Second, plan to keep your medications with you as you travel.
For example, if you are traveling by plane, pack your medications in your carry-on baggage. This eliminates the possibility of your medication being lost, and avoids the extreme temperature changes that can occur in luggage compartments.
If you are traveling by car, avoid placing medications in the glove compartment or trunk, where it could be exposed to extreme heat.
In addition to your medication, it is a good idea to put together a "personal medical kit." Contents can vary, but consider including the following: bandages, pain relievers (such as Tylenol®), lip balm, sunscreen, thermometer, and an extra pair of glasses and/or contact lenses.
Third, if you are planning international travel, there are special considerations you will need to keep in mind.
Because some illnesses such as hepatitis A are common in certain parts of the world, it may be necessary for you to receive special vaccinations prior to travel. For other diseases, vaccines may not be available, and therefore it may be necessary for you to adhere to specific behaviors to prevent infection. These behaviors might include avoiding insects, and using caution not to ingest unpurified water.
Specific requirements for all foreign travel destinations are available by calling the Centers for Disease Control at 1-800-311-3435.
Finally, check with your health plan to be certain that you will still be covered if you need to see a doctor while away from home.
