Medication, pacemakers and implants

Medication taken regularly

If you are required to take regular medication, you may encounter difficulties when flying into another time zone. If you have to take medication at regular intervals and are planning to fly across one or more time zones, we advise you to consult your doctor before your flight.


Since insulin injections are linked to mealtime rhythms, the time factor is especially critical here. In view of this, we have compiled a separate section for diabetics who are planning to travel by air (see “Flying with a medical condition” -> “Flying with diabetes”).

The pill

The best way to maintain the contraceptive protection offered by the Pill is by taking an extra pill if you are travelling west into a time zone that will extend your day by six hours or more. If you are travelling east, you can continue to take the pill at the usual time of day. We also advise you to consult your doctor on this in advance of your trip.

Carrying medication in your carry-on baggage

If you have to take regular medication, we advise you to take 1½ times to twice the amount you expect to need in your carry-on baggage. Flights can sometimes be diverted, and can also suffer occasionally substantial delays, even if you are already seated on board.

Taking medication and syringes through security checks

If you have medication or syringes in your carry-on baggage, it is advisable to carry a medical certificate with you (in English) confirming that these are medical supplies and/or materials which you need for your personal use.

Taking medication that needs to be kept cool in your carry-on baggage

SWISS cannot refrigerate medication for you. If your medication needs to be kept cool, a cool bag or vacuum flask may be appropriate, or you should discuss the options here with your pharmacist.

Losing medication

Just in case you should lose your medication, either during your journey or at your destination, you should get your doctor to provide you with a document stating your blood group and other key data about your health and medical condition, together with the names of the medications you take (including the names of the agents they contain) and the doses you require. You should also carry on you at all times all the documents you may need to obtain medical treatment or a prescription abroad. For further information, consult your doctor or contact your health insurance scheme.

Going through the security check with a heart pacemaker or metal implant

If you have a heart pacemaker or a metal implant (such as an artificial joint or metal wires or screws for a fracture), you will need to produce a medical certificate confirming this (in English) before negotiating the security check.
