It is well worth keeping a small stock of useful medicines at home in your (locked) first aid cupboard. For instance, pain killers (analgesics) such as Paracetamol, Ibuprofen or aspirin (children under 16 and people with asthma should not take aspirin), or Ibuprofen syrups  for children, Mild laxatives, Anti-diarrhoeal medicines, Indigestion remedy (for example, antacids) Travel sickness tablets, and Sunscreen – SPF15 or higher Sunburn treatment (for example, calamine).
