your essential medications
for diabetics this is your insulin, blood glucose tester, source of oral glucose, etc

analgesics such as paracetamol and ibuprofen

combine or sanitary pad to allow pressure on a bleeding wound - keep it compressed until bleeding stops - don't keep checking on it though
an aspirin in case of unexpected heart attacks if you are older than 35
a couple of triangular bandages with large safety pins
can be used as a sling for an injured arm or collarbone
can be used to splint an unstable fractured limb to a stick or similar
can be used to compress a bleeding wound in conjunction with combine or similar
cotton buds to remove dust or other foreign bodies from eyes or under the eyelids
cotton wool and Vaseline - can help with pressure sores / blisters and also the combination makes excellent fire starters
scissors
tweezers/forceps to remove splinters, etc
waterproof extra strong Elastoplast bandaids or similar for small lacerations or wounds
sterile dressings for open wounds

ideally a way to force potable clean water into wounds to irrigate them to stop infection
a 50mL syringe and blunt 18G needle is ideal to generate the pressure but a hole in a water bottle cap and squeezing the bottle will also suffice
ideally you should use around 1L of water to irrigate a sizable wound
