Medical Information

Health regulations

Valid certificates of inoculation and/or vaccination may be required in certain countries. This information may be obtained from the local health authorities in your departure city.


You are required to have a prescription or a note from a physician if you are carrying syringes or hypodermic needles for medical reasons. Please do not dispose of used syringes or needles without the protective cap or in the seat pockets. Inform our cabin crew should you need to dispose of a used syringe or needle while onboard the aircraft.

As a guide, Singapore Airlines will require medical clearance from a Singapore Airlines appointed doctor when fitness to travel is in doubt, as evidenced by recent illness, hospitalization, injury, surgery, or instability.

Medical clearance is also required in cases that require special attention or use of special medical equipment onboard, e.g., use of a stretcher, supplementary oxygen tank, or similar type of medical equipment. The objectives of medical clearance are to provide safe, healthy travel and high levels of customer satisfaction. When in doubt, please consult your medical practitioner on fitness to travel.

If medical clearance is required, please print a copy of the (Singapore Airlines' Medical Information Form (MEDIF)) and fax the completed form to the nearest Singapore Airlines office. Alternatively, you can obtain the form from any of our appointed travel agents or from any Singapore Airlines office.

Please note that there may be a delay in obtaining medical clearance if information provided is incomplete. Hence, it is advisable that you inform us of your travel plans early.

Generally, medical conditions should not inhibit you from flying. However, due to cabin pressure equivalent to an atmospheric pressure at 5,000 to 7,000 feet altitude, special precautions are sometimes required. For more information, please read the details below.

If you have any specific medical questions or concerns, please consult your medical practitioner on your fitness to travel and bring sufficient medication for your trip. Do note that we require medical clearance from our appointed doctor when fitness to travel is in doubt.

You should also ensure that you keep your medication in your hand luggage (not in the checked-in luggage) and have a letter on hand outlining your condition and medication(s), in case you encounter difficulties while overseas.

1. Asthma and other chest conditions
Asthma and other chest conditions   
Allowed to fly If your asthma condition is under control; it should not prevent you from flying.

Make sure you are well-stocked with your usual inhalers and avoid anything that may trigger an attack.


If you are wheezy before your flight, seek medical advice and treatment.

Special attention required If you experience breathlessness even at rest, cannot manage a 50-meter walk or one flight of stairs without breathing difficulty. If in doubt, get a formal medical evaluation from a medical practitioner who specialises in respiratory conditions.
2. Heart conditions
 Heart conditions  
Allowed to fly As a general guide, people with heart disease who are able to walk up 12 flights of stairs without any problem, or people whose hypertension is well-controlled, should be fit to fly.
Precautions If you recently had a heart attack (myocardial infarction), you are usually advised not to fly.
Special attention required Patients with frequent chest pains (angina attacks) should take extra precaution, as they are twice as likely to suffer an attack in the air as on the ground. They should consult their medical practitioner regarding their fitness to travel, and ensure that they have sufficient medications available to relief chest pains.
3. Diabetes

Ensure that you have your meals on time and an insulin shot in the middle of the night, if necessary. Special meals may be arranged at time of booking.


People with diabetes are often confused by long-haul travel across time zones, that is, when should they eat and when should they take their diabetic medication or insulin. An advice would be to stay on home time throughout the journey and readjust to local time only upon landing.

4. Deep vein thrombosis (DVT)
 Deep vein thrombosis (DVT)  

DVT is a blood clot that forms in the deep veins within the calf and leg muscles.


It is usually a spontaneous condition that occurs to people, especially those with heart disease, or the elderly. However, periods of prolonged leg immobility can also trigger this occurrence.

Symptoms Warning signs are pain and tenderness in the leg muscles, redness and swelling of the area.

For your safety, if you are prone to DVT, we require that you either sign a Letter of Indemnity or have your medical practitioner provide a medical certificate on your fitness to travel. Please also inform our reservations personnel of your condition when making your reservations.


While flying, we advise that you keep exercising your leg muscles. If possible, take regular walks around the cabin, except when the 'fasten seat belt' sign is displayed. While seated, perform a few simple exercises as shown in the well-being section of this site or refer to the inflight magazine or video.


Avoid alcohol as it increases the risk of developing such a condition. Instead drink more water to keep yourself hydrated as well as to maintain your physical well-being.

5. Others
Allowed to fly

Recent stroke:
A minimum of a three-week lapse is recommended for anyone intending to fly after a recent stroke. Medical clearance is needed to confirm your fitness to travel.


People with epilepsy are fit to fly but not if the last fit was within the last 24hrs. Medication to control epilepsy should be taken.

Precautions Epilepsy:
People who are prone to regular fits may need to increase their medication onboard on the advice of their medical practitioner, and reduce intake upon arrival at their destination.
Special attention Anaemia:
People with severe anaemia (blood count or haemoglobin less than 8.5 mg/dl) are usually not advised to travel.

Service dogs into and out of Uganda
A service dog accompanying its owner can be accepted in the passenger cabin in any class.

If you intend to carry service animals on board our flight, please contact your local Singapore Airlines office in advance to make the necessary arrangements. If your itinerary involves other carriers, separate clearance must be obtained from those carriers prior to travel. You must ensure that all government regulations and documentation requirements for the uplift, transit, and disembarkation airports are complied with.

The service dog is regarded as unchecked baggage and will be carried without charge, in addition to your free baggage allowance. The dog will not be occupying any seat and must not be seated in a location that would block escape routes in the event of an emergency. You are required to provide moisture absorbent material that will be placed on the cabin floor, underneath the dog at all times. The dog need not be muzzled and harnessed during the flight but a muzzle must be made available when required.

We do not accept any other type of service animal other than dogs.
