Allow at least one month for adequate health preparation before departing on an international trip. Sometimes it may take two to three months to ensure that all required and recommended vaccinations are given in their proper sequence. Immunization against Hepatitis A, for example, can take 6 months before full protection is afforded.

Check the immunization requirements of the country you are visiting. Certain countries might require vaccinations against various diseases before you are allowed to enter, or before you are allowed to return home to your country.

Consult your doctor before you embark on any trip. Your doctor may be able to prescribe extra doses of medication and give you some tips on maintaining your health.

Buy and pack a supply of all medications you take regularly. Make sure your supply is sufficient to last the entire trip, including any unexpected delays. Make sure you know the generic name of the medicine you take, as brand names vary around the world.

Carry your medical supplies in your hand baggage. This way if you are separated from your checked luggage, your health will not be at risk.

If you are leaving children behind, make sure you leave a signed emergency treatment consent form on file with your hospital.

Check your insurance coverage before you leave the country. Most insurance policies do not cover medical expenses incurred abroad, and medical expenses may be prohibitively high for travelers without insurance. Confirm your coverage and/or get extra insurance to cover you during your trip.

Carry some form of identification which states your special medical problems or needs. An identity bracelet or metal tag on a chain, stating your allergies to certain drugs or the fact that you are a diabetic or epileptic, is an example of identification which should be worn at all times.

Carry a copy of your prescription with you. If you wear glasses or contacts or take any kind of special medication, it is a good idea to carry your prescription in case you need replacements.

Have a thorough dental check-up before you leave on a long trip. A dental check-up just before you travel prevents the risk of painful and expensive treatment abroad.

Always carry copies of your health records. In a situation where medical attention is necessary, your medical records can help determine the best treatment possible.

Leave your medical information with someone who is readily accessible in case of an emergency. Your emergency contact should also have all your medical information in the event of a medical emergency.
