Always carry a small kit with some basic medical supplies and first aid equipment in your hand luggage.

Your kit should include:

Disinfectant or Antiseptic cream/lotionGauzeCotton swabsAdhesive bandagesMedical TapeSoap (preferably antibacterial)Isopropyl Alcohol (small bottle or towelettes)ThermometerWater purification tabletsScissorsTweezersSturdy plastic bagCollapsible scale (doubles as a splint)Small rubber tube (can be used as a tourniquet)Elastic bandageSmall, sharp blade

If traveling with children be sure to also include:

Children's strength aspirin, pain reliever, cold and allergy medicineOral rehydration tablets for children

Remember to carry a small supply of general medications. Medicines for cold and allergies, painkillers, anti-diarrhea tablets, and motion sickness tablets are useful items to have while traveling.

If you suffer from recurring problems like constipation, menstrual cramps, or hemorrhoids you should carry adequate supplies of medicines for these conditions as well. Sometimes, when traveling, the correct medications may not be available when required.

Bring an extra supply of prescription medications with you so that you don't endager your health if your trip is unexpectedly extended. Also, bring a hard copy of the prescription, just in case.

Remember, it is always better to carry a small supply of medicine with you than assume the country you are traveling to has your required medicines available. Many over-the-counter remedies are considered prescription drugs in other countries, or are just not available.
