While abroad store your medicines in a cool dry place. If you are crossing time zones, do not miss out doses especially if you are diabetic or have a heart condition. If you suffer from any recurrent illness or are on regular medication check with your general practitioner. You may find a check-up helpful to ensure that you are fit to travel. A referral letter can be useful in case you you need treatment while abroad.
Immunisations are important at all ages.
Having had a disease previously, such as polio or diphtheria, does not always mean you are immune. If you are prescribed anti malaria tablets, be sure to mention if you are on any other medication. Read the small print of your insurance policy which should include repatriation in case of illness and ensure there are no important exclusion clauses. Remember to take care to with food and water hygiene and to avoid insect and animal bites. It is important to get the 'all clear' from your own doctor or obstetrician before departure.
